Sony Alpha A7 Iii Vs A6600

by -154 views

The A6600 is the most advanced APS-C photographic camera in the E-mount series, and although information technology doesn’t necessarily have all the characteristics of a true flagship, it certainly deserves the championship of “high-finish model” in the line-up.

The A7 III is non at the top of the class in the A7 series, but it is by far the nigh popular. If you’re torn between a full frame or APS-C body, you lot’ll probable meet these 2 products. Hither is how they compare!

What they have in common:

  • E-mountain
  • 5-axis IBIS with 5.0Ev compensation (CIPA standards)
  • 4K video up to 30p, Full HD up to 120fps
  • Built-in Interval-time shooting
  • WiFi, NFC, Bluetooth connectivity
  • dust and moisture resistance

Ideals statement:The information supplied in this article is based on the official press release for the A6600 and our directly experience with Sony cameras.

one. Sensor

Although both cameras give you an output of 24MP (6000×4000), the sensor found within their bodies is unlike.

The A6600 uses the APS-C format whereas the A7 Iii has a 35mm format sensor, which is about 2.3x larger.

The A7 Iii sensor has a BSI structure (back-illuminated) whereas the A6600 chip features a copper wiring layer to improve transmission. Both have a front-stop LSI chip to increase the processing speed.

The A7 camera has an ISO range of 100 to 51200, with extended values going up to 204800 ISO, or downward to 50 ISO. The A6600 normal range stops at 32000, and the extended values get upwards to 102400 ISO.

RAW output is 14-bit on both cameras but only the A7 Three allows you to choose between compressed and uncompressed.

2. Autofocus

The A7 3 features a vast array of focus areas: 693 phase detection and 425 contrast detection points that cover 93% of the frame. Although not as fast as the flagship A9, the A7 III has proven to exist an excellent performer in our tests which include sports, birds in flying and low-light events. The tracking capabilities are also very skilful, fifty-fifty in challenging light weather condition.

The a6600 has 425 stage and contrast detection points that cover 84% of the sensor’south surface. More of import, the photographic camera features existent fourth dimension tracking which is Sony’southward latest autofocus marvel. It works by analysing colours, patterns, faces, eyes and depth when tracking the subject field. AI and machine learning applied science is added to the mix to brand the performance faster and more accurate. We tested this on the A6400 and it’s safety to say information technology is the best tracking arrangement we’ve experienced to date. It works for stills and video.

The A7 III has a bit of an advantage in low light because the minimum sensitivity is -3Ev versus -2Ev on the A6500 (both with an f2 discontinuity).

Both cameras characteristic Face up Detection and Eye AF. The latter works in real-fourth dimension and is bachelor for humans and animals (yous demand firmware iii.0 on the A7 III). Information technology works really well and is very handy when photographing all sorts of animals, although I couldn’t get in work for birds.

One affair that only the A6600 has is Middle AF for video. The A7 III can only use face detection when working in movie mode.

three. Speed

The A6600 has a slightly faster maximum burst speed of 11fps, whereas the A7 III stops at 10fps. At 8fps, they both brandish a live view with blackouts. With the electronic shutter, the APS-C model goes up to 8fps whereas the A7 tin can utilize its full speed.

Another small difference concerns the buffer capabilities.

The A7 III can record 177 frames in JPG or 89 in compressed RAW at 10fps. The A6600 does 116 JPGs or 46 RAW files at 11fps.

The A6600 has a maximum shutter speed of 1/4000s, whereas the A7 III goes upwardly to 1/8000s.

Both models include a start electronic curtain and a full electronic (silent) mode.

The A7 III likewise has an anti-flicker way that reduces flickering when shooting still images, which can be caused by fluorescent lights.

4. Video recording limit

The A6600 and A7 Iii share most of the same video specifications including 4K video recording with full pixel readout, South-Log2, S-Log3, HLPG profiles and much more.

Merely i thing the A6600 does that the A7 3 does non is lift the limitation of thirty minutes per clip usually found on this kind of product. Information technology is the 2nd Sony camera later on the A6400 to practice so.

5. Design

The about noticeable difference when it comes to blueprint is the viewfinder. The ane on the A6600 sits inside the body on the left side (rear view), whereas the i on the total frame camera protrudes from the meridian.

Sony has updated the design of the front grip on the APS-C photographic camera then that it looks similar in size to the one of the A7 III.

The A7 Iii is the largest of the ii, albeit non past much, and is also heavier:

  • a6600:
    120 x 66.nine x 69.3mm; 503g with battery and memory card
  • A7 Three: 126.9 x x 62.7mm; 650g with battery and memory menu

The A7 III has more than physical controls like the AF Joystick on the rear, the exposure compensation punch on height and the extra dial on the front end which makes exposure control somewhat easier than on the A6600.

6. Viewfinder and LCD monitor

The two products have a built-in electronic viewfinder with ii,359k dots of resolution (OLED panel).

The EVF on the full frame camera is larger (0.five-in vs 0.39-in) and offers a higher magnification of 0.78x vs 0.7x on the A6600. Still the A6600 EVF tin can work at 120Hz (100Hz if you are in PAL fashion) whereas the A7 has a refresh rate of nearly 60fps.

On the rear, you’ll find a bear upon LCD screen on both cameras. The touch on capabilities are mainly related to the focus area, with the possibility of activating tracking on the A6600.

The APS-C photographic camera has an advantage with regards to the tilting mechanism: it rotates up 180˚ and downwards 74˚, whereas the A7 3 monitor tilts xc˚ and 45˚ respectively.

vii. Memory and connections

The A6600 has 1 SD carte du jour slot, which can be accessed from the battery compartment at the lesser. Despite existence released in tardily 2019, it is however not compatible with the faster UHS-Ii standard.

The A7 Three on the other hand not only has a defended memory bill of fare compartment, simply besides offers two slots with the get-go beingness UHS-Two compliant.

Concerning the physical connections, both have a mic input, headphone output, micro HDMI output and a micro USB 2.0 port. The A7 3 has an additional USB C port.

viii. Battery life

The A6600 uses the same battery pack as the A7 3, the NP-FZ100, which has a larger chapters than the previous battery. There is a departure even so in the battery life rating.

The A6600 tin can tape nigh 800 frames (720 shots when using the viewfinder merely, or 810 shots with the rear monitor). The A7 III tin do 610/710 frames which means it is a bit more power-hungry. Go on in heed that these figures don’t reflect real earth conditions. I’ve managed to capture more than i,500 shots with my A7 3 in a day with just 1 battery.

Both cameras can be charged via USB port and come with a separate wall charger in the box.

If you lot want to extend the battery life further, you lot tin use the official VG-C3EM vertical battery grip for the A7 series. In that location isn’t ane for the A6600 at the moment but information technology might come up via third party brands in the near future.

ix. Lenses

Both cameras use the aforementioned mount then you can employ full frame lenses on the A6600 and APS-C lenses on the A7 III (with a crop) if you wish.

Now while the possibility of having interchangeable lenses from unlike formats is a welcome choice, it is worth dedicating a few paragraphs to the APS-C and 35mm lens selection.

Sony has adult an impressive array of total frame lenses over the past five years, and A7 owners can also count on products from Zeiss, Samyang, Sigma and Tamron. All these lenses volition work flawlessly on the A6600 but some of them might be a bit also large (or expensive) for such a photographic camera.

If you want to proceed your prepare up as minor and meaty as possible, then you tin plough to the APS-C range but it is non as well furnished as the total frame range.

Sony recently appear a xvi-55mm f/2.8 zoom, which is the outset 2.8 zoom in the serial for APS-C, and y’all tin can find fast ane.8 and ane.4 primes (thanks to Sigma in item). There is an overwhelming number of slow telephoto zooms withal, including the recently announced 70-350mm.

x. Toll

The A6600 is being launched at the retail price of $1400, £1450, €1600.

As y’all can imagine, the A7 mark Three is more than expensive at around $2000, £1800 or €2000.

These prices are for the body but. Special offers and instant rebates might reduce the toll for a express time in certain countries (peculiarly for the A7 Iii which is an older model).


For some, the difference in sensor size will be the sole determining factor in making the decision between the 2. For others, the disparity in cost volition exist enough.

The popularity of the A7 III has reached levels never before seen in the mirrorless earth, and it is entirely justified. The quality yous get at this price is hard to crush at the moment. If you’re looking for a groovy full frame camera, this is one of the very best.

The A6600 is no less interesting in my opinion. It brings interesting improvements to the APS-C series (battery life to proper name 1), offers outstanding autofocus operation, and remains compact and light despite its larger grip.

Perhaps information technology lacks a few actress specifications that would go far more appealing, such equally a significantly faster burst shooting speed or updated video specifications. But if you want a more than compact body and to spend less, it’s hard to go wrong with the A6600.
