I’ve been shooting with both the Sony FE 70-200mm f/four G OSS and Iron 70-200mm f/ii.8 GM OSS for a few days. It’s a pair of lenses that I’ve been wanting to compare for ages.
In the UK, these eyes retail for £1,509 and £2,500 respectively. In the US it’s $ane,398 and $ii,598. That’south a pregnant cost deviation then many Sony A7-serial users are weighing up which they should buy.
Sony FE 70-200mm f/4 vs f2.8: The fundamental differences
Aside from the one finish difference in the maximum aperture of the 2 lenses, in that location are a few other differences between them. The f/4 version has a minimum focus altitude of 1-1.5m when focusing with the AF system and 1-i.35m when focusing manually. The f/2.viii optic can focus equally close every bit 0.96m regardless of the focal length and focusing method.
This ways that the f/4 lens has a maximum magnification ratio of 0.13x while the f/two.8’southward is 0.25x.
Their structure is too unlike. The f/4 is synthetic from 21 elements in 15 groups while the f/2.8 has 23 elements in 18 groups.
Naturally, there’s a size and weight difference. The FE seventy-200mm f/4 Thousand OSS measures 80 x 175mm and weighs 840g without the tripod mount. Meanwhile, the Iron 70-200mm f/two.eight GM OSS is 88 10 200mm and 1480g. It’due south the weight divergence that you detect in utilize rather than the size.
The f/4 lens also takes 72mm filters while the f/2.8 optic has a 77mm filter thread.

As usual, I’ve been making an Ottofocus comparing with the two lenses by photographing my dog, Otto. I’ve been shooting with the A7 III and A7R Three, swapping the optics between the ii cameras.
Even in quite dim daylight, I didn’t really detect any divergence in the speed of focus conquering. And the tracking adequacy seems very similar whichever lens I use.
I’ve also been shooting in the photographers’ pit at Fairport’s Cropredy Festival. This has given me the chance to compare how the lenses perform with a range of lighting atmospheric condition. And again, they give very similar performance with the Sony cameras’ Eye AF is proving very useful.
In very low low-cal conditions, there’s a slight suggestion that the cameras’ AF systems cope a bit amend with the FE 70-200mm f/2.8 GM OSS mounted. Just to be honest, the Iron seventy-200mm f/iv M OSS does such a good job it’s difficult to say for sure. I tried continually swapping between the ii lenses in the dark conditions and there were very few occasions when either lens missed the focus.
Obviously, with an actress stop of light getting through the Fe lxx-200mm f/2.eight GM OSS there will be occasions when information technology enables the AF system to work and the Iron seventy-200mm f/4 Grand OSS doesn’t, merely I’ve yet to encounter it. That’s despite shooting in very overcast conditions and at night during the festival.
In short, the f/4 lens stands upwards really well confronting the f/2.8 with respect to autofocusing.
Both lenses are capable of capturing a lot of abrupt particular. On the whole, however, the Atomic number 26 lxx-200mm f/ii.8 GM OSS does a better chore of rendering that item across the frame.
The 200mm end is commonly the nearly used point of a 70-200mm lens, so I’ll look at that in detail.
At this focal length and f/22, the FE 70-200mm f/2.8 GM OSS is a little sharper at the eye and better in the corners than the f/four lens. At f/two.viii, however, the FE seventy-200mm f/ii.8 GM OSS isn’t equally abrupt equally the Atomic number 26 lxx-200mm f/4 Grand OSS at f/iv at the centre.
When set to f/4, the lenses are quite closely matched for detail at the centre. And although still a little soft, the f/2.eight optic is better at the corners. At f/5.6 both lenses are very sharp at the centre, but the improvement in the corners from the f/2.8 lens is more noticeable.
Closing downwardly to f/11 or f/sixteen significantly enhances corner sharpness from the f/2.8 optic. The f/4 lens’ corner sharpness likewise improves, but not to the standard of the f/2.viii.
By f/22 both lenses evidence slight signs of diffraction. It means the results are but a shade softer than those shot at f/16. But they are still very good.
Distortion and Vignetting
Neither lens is troubled excessively by distortion or vignetting. However, at that place’south a trivial more than pincushion baloney visible at the 200mm end of the Iron 70-200mm f/iv K OSS than the Atomic number 26 70-200mm f/two.8 GM OSS. It doesn’t leap out at yous though, even if the scene has lots of direct lines.
Similarly, there’southward a hint of barrel distortion with both lenses at the 70mm end.
If yous’re shooting a compatible subject area, you lot may notice a little corner shading (vignetting) when shooting at the widest aperture with either lens at 70mm. It’southward more noticeable with the f/4 lens, but it all but disappears when the discontinuity is closed by a stop. However, it’south controlled well so it’s really non much of an consequence.
Sony Atomic number 26 70-200mm f/four vs f2.8: Conclusion
The Sony FE lxx-200mm f/4 G OSS is an splendid lens. It’s a nice size and weight for utilise with a Sony A7-series photographic camera and it lets the AF systems in the A7 Three and A7R III do their thing. Information technology means you lot get moving subjects sharp and the Center AF works well.
Its sharpness at the eye of the frame is superb. Notwithstanding, it can’t match the Iron seventy-200mm f/2.8 GM OSS into the corners. The f/2.viii lens maintains image quality just a bit ameliorate towards the edges, specially if you stop down a footling.
And of form, if yous shoot in very low light on a frequent basis, that extra stop of lite brought by the f/2.eight is useful. However, at the 200mm terminate, images shot at f/2.8 aren’t quite as sharp at the centre equally those shot at f/4 with the Fe 70-200mm f/2.eight GM OSS.
Should I purchase the Sony Iron 70-200mm f/iv K OSS or FE 70-200mm f/two.eight GM OSS?
For the majority of photographers, the FE 70-200mm f/4 Chiliad OSS makes a swell option. It strikes a good balance between price and image quality. However, if yous want the accented all-time results and you lot don’t heed the actress weight, the FE seventy-200mm f/2.eight GM OSS is the lens to go for.
