Tamron 150-600 G2 Vs Sony 200-600

By | 14/10/2022

The lens choice for Sony Due east-mount users has grown considerably in the by few years. I retrieve testing several cameras with the 100-400mm GM and 1.4x teleconverter, which at the time were the only options to get close to a 600mm accomplish (excluding adjusted lenses of class).

Today, there is a much meliorate variety of native telephotos, not only thanks to Sony releasing more products, simply also Tamron and Sigma.

In this commodity, I take a await at iii of the most popular options. If yous’re hesitating betwixt them, I hope you’ll discover this article useful.

Ideals statement: nosotros rented the Sony and Tamron lenses, whereas the Sigma zoom was kindly provided by Sigma Great britain. We were not asked to write anything most these products, nor were nosotros provided with whatsoever sort of bounty. Inside the article, there are chapter links. If y’all purchase something later on clicking the link, nosotros volition receive a pocket-sized commission. To know more well-most our ideals, yous tin visit our full disclosure folio. Requite thanks you!

Design and Ease of Use

Let’south tackle dimensions and weight first. The Sony is the longest, largest and heaviest of the three. It is also the simply one with an internal zoom mechanism, which means that it doesn’t extend when zooming in.

The Sigma closely follows the Sony when it comes to weight and bore, but it is 5cm shorter when retracted. When extended to 600mm nonetheless, it becomes a few centimetres longer than the Sony lens.

The Tamron is the smallest and lightest of the three, and y’all come to really capeesh its more than than compact dimensions. It remains shorter, albeit non past much, when extended to 500mm.

All iii lenses are weather sealed and feel very well built.

The Sony has the smoothest zoom ring but in that location is no pick of locking it at whatsoever position.

That of the Tamron has more resistance which I don’t dislike to be honest, considering in that location isn’t a lot of friction, and the ring has a ameliorate adventure of staying in identify when you set it. The arc of rotation is brusque at only 75˚, which means yous tin can become from 150mm to 500mm and vice versa with a relatively small twist. When not in apply, you tin lock the zoom at 150mm with the dedicated switch.

Tamron’s designers likewise added something very clever that they call Flex Zoom Lock mechanism: the zoom ring tin can exist clutched forrad to be locked in whatsoever position.

The execution is a bit disappointing unfortunately, considering if y’all concur the lens with your hand on the zoom band, which is the nearly natural position, you finish upwards moving the ring upwardly and downwards all the 4th dimension while taking pictures. In other words, it could accept done with a stronger machinery. To make it work, you lot demand to concur the lens with your manus touching some other function of its surface, which is not e’er comfortable.

The Sigma lens has a dedicated torque switch on the side to lock the zoom ring at 150mm, or cull two unlike levels of resistance: Tight or Smooth. The T setting offers a high degree of resistance, so it’southward very unlikely yous’ll movement the ring by mistake.

The switch is a bit capricious at fourth dimension (at least on my copy), and changing positions tin be a tedious operation because the switch refuses to move. The workaround is to rotate the zoom ring a fiddling until information applied science works once more, or even zoom all the manner out to 150mm.

The Sigma lens has what the visitor calls a Dual Action Zoom mechanism, which ways that y’all can employ either the ring to zoom, or pull the forepart of the lens dorsum and forth. Pulling dorsum and forth is a quicker solution every chip the rotation arc of the zoom ring is the longest amidst the three zooms.

So we take the concrete controls, and hither all three lenses offer like options, including:

  • AF / MF switch
  • Focus limiter switch with three positions
  • Optical Stabilisation switch

The Sony and the Tamron take a second OSS switch with three modes that control how the stabilisation behaves (more on this in the defended affiliate further down), whereas the Sigma offers ii modes just, incorporated in the On/Off switch.

The Sigma has one extra switch you won’t detect on the other two lenses, chosen Custom Switch. On newspaper, with the aid of Sigma’due south USB Dock and Sigma’south Optimization Pro software, you can create 2 separate combinations of settings related to the stabilisation and focus limiter, that you lot can so retrieve at whatever time with the switch. At the time of publishing this article, the Eastward-mountain version of the Dock is not nevertheless bachelor.

The Sony and the Sigma have a custom push button, repeated three times around the barrel, whereas the Tamron has none.

The Sony has a clever quick release mode for the tripod collar: just rotate the lock lever and press the safety push to remove it. Quick and piece of cake. It’s a shame that it doesn’t fit an Arca Swiss tripod caput straight.

The Tamron features the classic tripod neckband pattern, and you can remove it entirely by unscrewing the defended knob. It is compatible with Arca Swiss tripod heads.

Sigma has opted for a different solution that I don’t like as much because it doesn’t let you to take the plate out hands. You demand to remove four small screws (thankfully the hex fundamental is provided) just you are even and then left with a hump. The plate is Arca Swiss compatible.

All iii lenses come with a plastic hood and plastic caps. Sigma also provides a squeamish soft padded comprehend, an culling to the default plastic front cap.

Finally, strap attachment points are available on the three lenses.

Field of View and Discontinuity

The zoom range is non exactly the aforementioned for each lens: the Sigma and the Tamron outset at 150mm versus 200mm on the Sony, and the Tamron ends at 500mm versus 600mm on the other ii lenses. Here is a visualisation of the difference in existent globe use.

The fastest discontinuity range is likewise unlike. Below I reported the largest aperture bachelor at each phase of the zoom range.

Sony Fast. aperture
200-299mm f/five.6
300-600mm f/half dozen.iii
Sigma Fast. discontinuity
150-173mm f/five
174-365mm f/5.one-half dozen
366-600mm f/half-dozen.3
Tamron Fast. discontinuity
150-241mm f/5
242-389mm f/5.half-dozen
390-499mm f/half-dozen.three
500mm f/half dozen.7

Notation that the divergence in terms of exposure betwixt f/v and f/v,one-half-dozen is minor (ane/3 of a total stop), and that of f/half-dozen.3 and f/vi.seven even smaller (nearly 1/one-half-dozen of a total stop).

Optical Quality


All the sharpness tests were performed with the A7R 3.

Before analysing the images side by side, hither is a summary of the performance for each lens with the about important points to remember.

Sony FE 200-600mm Key Takeaways near sharpness:

  • optimal sharpness is found at f5.6, f6.3 and f/8 from 200 to 600mm
  • At 500mm and 600mm, acme sharpness is at f/viii, just f6.3 and f/eleven are very close
  • f/eleven and f/16 evangelize decent quality beyond the unabridged zoom range
  • f/22 delivers softer images due to diffraction, just the quality is acceptable at 600mm

Sigma 150-600mm Fundamental Takeaways almost sharpness:

  • from 150 to 300mm, acme performance is constitute at f/five.6
  • from 400 to 600mm, the all-fourth dimension results are at f/eight
  • good quality at f/xi, decent at f/sixteen
  • f22 is softer upwards to 400mm, simply acceptable at 500 and 600mm

Tamron 150-500mm Key Takeaways nearly sharpness:

  • From 200-500mm, sharpness is at its peak at the fastest apertures and f/eight
  • At 150mm, it is a chip softer at f/5, but information technology improves from f5.one-half dozen already
  • f/11 maintains a good level beyond the unabridged zoom range, f16 is very decent at 500mm
  • f22 is soft, except at 500mm where it is acceptable

To avert bloating the commodity likewise much, I didn’t include every unmarried discontinuity and focal length in my side by side shots. Instead, I concentrated on the examples that show you the near important differences betwixt the 3 lenses.

At 150mm, the Sigma is a bit sharper at f/5 and f/v.six, then information engineering is the Tamron that has a small reward at f/viii. Either style, we’re talking almost small differences that are not similar shooting fish in a barrel to find at outset glance. The quality is very like at f/eleven, f/16 and f/22.

At 200mm, they all share similar results at f/5 and/or f5.half dozen. At f/8, the Tamron is a bit softer, whereas at f/11 and f/16 the Sony does slightly ameliorate. Over again, nosotros’re talking virtually very small differences.

At 300mm, the level of sharpness is most identical at f/five.6 and f/6.iii. At f/viii and f/eleven, the Sigma is a fleck softer than the other two lenses. At f/16 and f/22, they are all very close over again.

At 400mm, the Tamron has the edge at f6.three, and the Sony does better than the Sigma. Over again, nosotros’re talking about pocket-sized differences. At f/8 and f/xi, the Sigma is slightly backside the other 2 zooms.

At 500mm, the Tamron really starts to polish at the fastest discontinuity, but the other two lenses are shut. From f/8 to f/16, the Sony and the Tamron are at the aforementioned level, with the Sigma right behind them.

Finally, at 600mm, the Sony is the sharpest past a small-scale margin, whereas from f/8 to f/11 both the Sigma and Sony are at the same level.


These are non lenses that evangelize outstanding bokeh and flossy out of focus areas. In fact, on many occasions, you lot’ll accept to bargain with an out-of-focus background that appears more distracting than yous would similar it to be only, to be honest, information engineering science’s no unlike from what I saw on other lenses of this kind. In this respect, the 3 zooms evangelize similar results.

Of form, when y’all zoom all the way in, or have a more distant groundwork, the blur intensity will increase and make the background less distracting.

1 of the almost challenging situations is a small-scale bird surrounded by branches. In the examples beneath, y’all tin can detect how some areas look very ‘decorated’ with hard edges and double lines.

In other situations, y’all’ll besides discover a hint of a swirly event in the background.

The only fashion you’re going to come across flare is with direct calorie-free in your frame, and here all three lenses can showroom visible ghosting.

The Sony tin render larger ghost flares than the Tamron, whereas the Sigma too produces rainbow flares.

Other Characteristics

All 3 lenses deal with chromatic abnormality really well, and I couldn’t find any visible traces anywhere. In a very high dissimilarity scene, the Sigma may showroom a tiny bit on the edges, but the level is then low that you lot lot shouldn’t worry most it.

When the lens profiles are enabled on the RAW file, vignetting is well corrected on the Sony and Tamron, at the shortest and longest focal length. The Sigma still has some left at 150mm and f/5, but yous tin easily correct it in post.

There is pincushion distortion on the three lenses but that is minimised when the lens profile is applied. Curiously, the Tamron is the ane that needs less correction than the other two models.

Finally, y’all might accept noticed in some of the adjacent images that the Sony tends to return cooler colours in comparison to the other two lenses.

Autofocus and Transmission Focus

Having already had experience with the 200-600mm on multiple Sony cameras (A7R IV, A9 Ii, A1), I was curious to run into if I would go the aforementioned fast functioning from the other 2 lenses.

With static subjects, all three lenses deliver fast and authentic focus, and I didn’t come across whatever unwelcome behaviour or item problem during my two weeks testing them.

Even with pocket-size-calibration birds perched on a tree, and lots of branches and leaves effectually them, I got good results using the smallest AF bespeak available (Flexible Spot Due south) or the Expand Flexible Spot area. Sure, in that location were a few misses if the bird was moving backside a branch, and sometimes the body would be more in focus than the head, but these are more than due to the challenging situation itself rather a camera/lens problem.

Birds in Flight

For birds in flying and my usual carmine kite examination, I found some differences yet, testing the iii lenses with the same camera (Sony A7 III).

The Sony and Tamron zoom delivered excellent performance, giving me the all-fourth dimension score I ever registered with the A7 3. The Sigma, still, was most ten% less efficient (you can find out more than nearly my BIF score in my defended article).










Notation: the first percent (green) calculates authentic focus just, whereas the 2d (blueish) includes sligthly soft results.

The A7 III struggled more with the Sigma 150-600mm. The number of out-of-focus shots was college than the other two lenses, and in that location was a lack of focus precision in several images. I did the test twice with the Sigma to be certain, and I got the same results each time.

Transmission Focus

Concerning manual focus, the focus ring on the Tamron lens is non equally polish every bit the other two at start glance. However, after focusing manually several times for my sharpness and shut-upwardly tests, I found that it is the Sigma lens that gives yous the almost accurate and pleasant experience. With the Tamron and the Sony, it is a scrap more than than hard to smash focus precisely.

That said, the Sigma rapidly turned my sharpness examination into a nightmare when I realised that the focus bespeak was shifting when irresolute aperture. Focus shift is a trouble that ordinarily occurs with fast aperture lenses: the sharpest focus airplane moves astern or forwards when you stop down. It is acquired by spherical aberration (y’all can read this excellent caption on Photographylife).

I never experienced it on a lens with ho-hum apertures similar f/five and f/one-half-dozen.iii, and information engineering science could exist that not every sample is afflicted. For example, The Digital Moving picture tested the zoom and stated that this particular issue didn’t occur on their sample.

It might not be a concern system for y’all either fashion, considering I but found this trouble during my sharpness test using transmission focus. In real world use with AF, the lens seems to slice of piece of work unremarkably. Merely, if for some reason you need to focus manually and capture the same subject at dissimilar apertures, it’due south worth testing the lens to run across if information technology has the problem or non. If it’s there, y’all lot’ll have to re-focus every time you change apertures.

Minimum focus distance

Finally, we have the minimum focus altitude. Hither the Tamron shows improve capabilities by maintaining a similar magnification at 150mm and 500mm. The minimum focus at 500mm especially is much shorter than what the Sigma and Sony tin exercise at 600mm.

The Sigma offers first-class shut-upward capabilities at 150mm, outperforming the Tamron by a minor margin.

The Sony is less impressive, especially at 200mm.

Optical Stabilisation

I performed my usual tests to come across how far I could go at irksome shutter speeds earlier seeing a decrease in sharpness and details. I tried various tedious shutter speeds and took x pictures consecutively at each speed, using a subject like the one in the moving picture below. And and so I analysed how many images were sharp, and how many were ruined because of move blur.

Sony 200-600mm Key Takeaways about OS:

  • To accept peace of mind, you lot need to stay at effectually i/125s or faster, at 200mm and 600mm.
  • Slower shutter speeds such as i/30s, i/15s or fifty-fifty one/8s are possible, simply the keeper rate decreases considerably.

Sigma 150-600mm Cardinal Takeaways well-virtually Bone:

  • I got a perfect score at one/60s, both at 150mm and 600mm, and then the Sigma seems to be 1 stop more than than efficient than the Sony lens overall.
  • Deadening shutter speeds are possible only the keeper rate is lower as well, and so make sure to take multiple pictures in a row

Tamron 150-500mm Key Takeaways nigh Bone:

  • Information technology tin tin handle 1/60s at 150mm without problems, merely information technology’southward improve to stay at 1/125s or in a higher place when working at 500mm.
  • Forget annihilation slower than i/30s when working at 500mm

Hither are all the results.

On the Sony and Tamron lenses there are three modes for the optical stabilisation:

  • Style i

    compensates in all directions
  • Mode 2

    is designed for panning shots, then for example it volition merely recoup for vertical shakes while panning horizontally
  • Mode 3

    is designed to requite yous lot a more stable view in the viewfinder. It compensates in all directions like Mode one.

On the Sigma, in that location are merely 2 modes and they work exactly like i and ii described above.

Information technology’s not immediately easy to understand what Mode three does exactly, only it’s really non complicated.

With Fashion ane and Mode two, you lot don’t see the stabilisation effect in the viewfinder until you printing the focus button, or half press the shutter release button. In other words, stabilisation starts to work when y’all lot press either of these buttons.

With Fashion three, the stabilisation preview is active even if you don’t press whatsoever buttons. In other words, it starts working every bit soon as you plough on the photographic camera.

Both Sony and Tamron say that Fashion three is useful when post-obit erratic and unpredictable subjects. I explanation for this is that when the stabilisation is activated, at that place can be a sudden shift in your limerick, or jerk, as a outcome of the transition from a not-stabilised prototype to a stabilised epitome, or vice-versa.

With Mode iii, this sudden shift in the frame doesn’t happen considering stabilisation is active at all times, whether I start focusing and taking pictures or non.

And so if you are post-obit unpredictable subjects that modify direction all the fourth dimension, and you’re panning very fast in dissimilar directions, Style 3 can aid you frame your subjects more precisely.

With that said, I didn’t detect that Manner 3 gave me a relevant do good when taking pictures of the red kites flight. However, I observe data technology useful for static subjects when composing at 500mm or 600mm hand-held. The stable view in the EVF helps y’all frame meliorate and move the focus point with more than precision.


The Sony 200-600mm is the only lens in this test that is compatible with teleconverters: the ane.4x and 2.0x that are designed for Due east-mount specifically.

Hither is the zoom and discontinuity range you lot become with each teleconverter:

  • TC 1.4x: 280-840mm, F8-nine
  • TC 2.0x: 400-1200mm, F11-thirteen.

With the TC 1.4x, the level of sharpness remains very good from f/nine to f/xvi. In fact I’d say the deviation in quality without the converter is not-existent. Stopping downward to f/22 gives you lot decent result, whereas from f/32 diffraction is more visible.

With the TC ii.0x, the results are similar, if non a tad less abrupt, merely it really is a small-scale difference. The all-time results are found at f/xiii and f/sixteen, with f/22 existence more than than acceptable. F/32 is decent all things considered, merely after that the image is much softer.

I oasis’t noticed a substantial decrease in autofocus functioning, at to the lowest degree when working with static subjects. I didn’t observe the take chances to use the converters for birds in flying.

Tamron hasn’t released whatsoever converters for Due east-mountain cameras, whereas Sigma has designed two TC uniform with mirrorless bodies, simply simply for L-mountain products and so far (Panasonic S, Leica SL and Sigma fp full frame cameras).

According to a reader on Marc Alhadeff’southward Sony Alpha Web log, the reason Sigma hasn’t release an E-mountain version of its teleconverters is a simple question of agreement: Sigma is licensed from Sony to design E-mount lenses, merely non E-mountain teleconverters.

That’south a shame, because teleconverters would brand the Sigma lenses similar this 150-600mm, as well as their smaller 100-400mm, more than highly-seasoned in my stance.


The Sony 200-600mm is the nearly expensive lens mentioned here, with retail prices beingness around $2000, £1600 or €1800.

The Sigma 150-600mm is less expensive with a cost of $1500, £1200 or €1400.

The Tamron is the near affordable option depending on where y’all lot alive. It can exist institute for $1400, £1380 or €1600.

Video Review

Yous tin watch a video version of this article on our YouTube channel.


This was a very interesting comparing to produce considering the results I encountered were more often than not unexpected. Mainly, I was pleasantly surprised past the performance of the Tamron 150-500mm. Certain, you have to settle for a shorter focal length at the telephoto finish, and at that place are no teleconverters to recoup for that. But what the visitor did here is offering a more meaty and lightweight alternative without sacrificing quality.

The Tamron delivers the same level of optical operation as the Sony lens beyond nearly the entire zoom range when information engineering science comes to sharpness. The AF motor is also as proficient as the Sony, and the optical stabilisation provides practiced support when shooting manus-held. Information technology’due south well built and has most of the controls a lensman could maybe desire (it is but missing a custom button). Add together in the competitive price, and I take no hesitation in proverb that the 150-500mm is the all-time bang for the cadet hither.

Isn’t 500mm likewise short? Sure, it tin exist. At that place volition exist times that you want to zoom in more than. You take to accept into consideration how often y’all intend to apply the lens, and for what purpose exactly.

For example, if y’all are mainly interested in nature reserves that permit you to get shut to the animals, information technology tin be all that you need. Another idea is if you own a Sony camera with a loftier resolution sensor, you lot can get a bit of actress achieve with the APS-C style (or past cropping in postal service). A Sony APS-C model is also a good candidate for this lens.

If budget is not an result, and yous want peace of heed about getting the lens that delivers the best operation overall, the Sony is your answer. Information technology’s larger, heavier, only is every bit well flawless on all levels, and it is the but lens that can extend your attain further with teleconverters, offer more than possibilities when you tin can’t become shut to your discipline surface area (something that happens a lot with wildlife photography).

So nosotros have the Sigma and I’ll acknowledge I’k a fleck disappointed with it. Certainly, it delivers good optical quality overall, merely the AF motor’southward performance was slower than expected for fast moving subjects such as birds in flying. The lens’ design doesn’t offer a real reward in terms of size and weight, and there are no teleconverters. The simply surface area where it shows meliorate capabilities is optical stabilisation, but non to the indicate of making a relevant departure.

Would I recommend the Sigma at all? Well, depending on where you alive, information technology could exist less expensive than the other 2, and that might be all you need to hear. Just if the toll is shut to that of the Tamron, I would personally go with the latter.

Choose the Sony Atomic number 26 200-600mm if:

  • you want the all-time quality and peformance
  • you want the actress achieve with the teleconverters

Cull the Tamron 150-500mm is:

  • you lot want a more affordable lens without sacrificing quality and operation
  • you lot want to carry around a smaller and more meaty lens

Choose the Sigma 150-600mm if:
