Sebboh, The Sony FE 70-200mm F/4 is almost exactly the same size and weight as the Nikon 70-200 F/4 VR lens. Why would you expect have expected the lens to be even bigger than an SLR version?

The AF is fast , that's for sure. I don't read nor speak Korean but I got the impression that the lens tested pretty well there. When is the lens going to be available in the US again? I thought it should be available yesterday, 21 April.

because of the extra distance the nikon has from flange to sensor. telephoto designs don't change much for mirrorless and the extra 20mm of flange distance has to be added to the lens rather than the camera. i'd expect the lens to be 10-20mm longer than the canikon versions with the same diameter.

When you have more freedom of placement, aberration correction can be more relaxed. The question is WHEN you can actually gain something from this.
The main (master) lens in most mid-tele constructions is in most cases and constructions about 100mm. The front group (most often a Donder's type afocal) then adjusts the system total from ~70 to ~200 by varying the size of the projection sent to the front pupil - this is what keeps aperture constant when you zoom...

Having slightly more freedom of construction might make the lens smaller, but seeing that most modern 70-200 types have rearmost elements (BFD) that aren't even close to the mirror-clearance minimum I'd guess that no performance is gained by making the lens grow "backwards".

Hence; most large aperture constant zooms are pretty constant in size from front lens to sensor no matter what format or flange distance you construct them for. As long as the format isn't 6x6 or larger...

Hi All,

So I did a comparison b/w the A7r + 70-200 F/4 and my 5DII + Canon 70-200 F/2.8 II with both lenses at 200mm. I will try to post some comparison shots when I get a moment but here are my initial impressions.

Sony lens is definitely producing a good bit more resolution on the A7r, even wide open at f/4 vs. the 5DII with the Canon lens stopped down to f/4 (where the Canon is laser sharp).

Corners look great to me at 200mm even at f/4 but they appear excellent at f/8

vignetting seems very well controlled wide open

Autofocus is surprising fast when decent light and contrast is present. Not quite as lightning fast as the 5D with the Canon beast but still very quick. In low light / contrast situations it's a completely different story with long focus times and some hunting, clearly no match for the phase detection on the 5DII combo. I found the lens is very hesitant to focus at or near MFD, although I can not say for sure.

Size / Weight is a very personal assessment, but from my point of view the Sony combo is not excessive. Personally, if I am shooting any type of 70-200 not on a tripod, I am usually doing so with a "sling" style strap so I am not hand-holding for hours on end. With the RRS L-bracket I find the combo to be comfortable enough to where it would not deter me from using it, and it is significantly lighter than the Canon combo (clearly, given the heft of the f/2.8 II (1 extra stop) zoom and the weight of the body)


I have not taken any real world shots yet but I will update my thoughts when I do.


Best,

Dimitri Kavalieros

pixelreaper, where did you get your Sony 70-200 f/4 copy from? I'm looking to get this lens too. Even though i already have the Canon f/2.8 ii version, i still prefer native lens instead of using the metabone adapter. AF only work on couple Canon lenses.

Hi Bubble,

I was amongst the first pre-orders on Amazon.

I agree with you regarding the native lens, especially with one as large as a 70-200. While I love the Canon (my favorite lens on the 5DII along with my 17 ts-e), I just can't see using this lens on the A7r very often.

I am still undecided on the Sony 70-200mm because it is more limited in use for me. I think this is because I would miss having the C-AF performance of the Canon combo for sports and kids. Also, for a lighter weight travel tele zoom, mainly for landscapes, there might be a cheaper alternative to the Sony. I will update my thoughts as I get more time to use the lens.

Thanks,

Dimitri

Dimitri,
Thanks for your first impression. Did you get yours from a retailer here in the US? Never mind, Amazon, it is. So, it is readily available then, huh?

Amazon lists it as "Usually ships within 3 to 4 weeks."

Got mine yesterday from a Sydney city retailer. They had three in stock. Couldn't resist.

So far, so good. I've yet to critically examine the files but build quality is excellent. OSS switch on lens is welcome. Focus is fast and more importantly, accurate. Hood is smaller than I was expecting (it's not a petal hood). Balance with A7 is very good. I've tried with grip on and off. Tripod collar is pretty smooth and easily removed if required.

Pics if I get something reasonable, this weekend.

If you have a chance, please post about the OSS and handhold-ability below 1/f. Thanks!

Has anyone compared this to the ef 70-200 f4 is? They seem to be more or less the same size, and the canon lens is legendary

I got to shoot with one for a week. I found it awesome up to 150mm, but rather soft longer than that. I suspect my copy was a bit decentered at the long end so I'm reserving judgement until I get to see more copies.

I'm interested to see how this does for fast sports. Its the only reason I still keep my D700 & 70-200/2.8VR2.l

Hi everyone,

As promised here is a quick test of corner performance of this lens at approximately 70mm, 100mm, 135mm & 200mm at f/11. The test is my standard resolution and chromatic aberration torture test; the live oak trees in my back yard on a bright cloudy day.

Test notes-

-All images were taken with the Sony A7r at ISO 100 on a very sturdy RRS tripod with OSS turned off.
-These crops of the top left portion of the frame shown at 100% (~1300x800), were converted from raw in LR 5.4 at JPEG 90% with my standard Sharpness 40, Radius 1.0, NR set to 0, Lens correction and Chromatic Aberration correction turned off.
-Some of the shutter speed were very slow (1/10) so you may see some motion blur from a slight breeze, but I think you will still be able to see the edge performance is very strong.
-I am finding the lens to be beautifully sharp corner to corner with only a negligible fall off in performance on the edges. Although the autofocus performance has been very slow in low light, I have not had any issues with it in good lighting. It definitely makes a interesting addition to my current landscape kit listed below-

A7r
Samyang/Rokinon 14mm FE mount
Canon 17 TS-e
Canon FDn 20mm
Zeiss FE 35mm (very sharp corner to corner at f/4 and smaller! not sure why this lens is not getting better feedback)
Zeiss FE 55mm
Sony FE 70-200 F/4 G


Thanks,
Dimitri Kavalieros

Also to add to the above, the right side of the frame showed very similar and balanced sharpness, like the left. The center is even sharper with very good micro contrast and resolution.
