Marcin 3M: Funny observation on this image:

http://www.dpreview.com/sample-galleries/9303055313/sony-fe-24-70mm-f2-8-gm-samples/4452946735

Guys are in-focus (sort of, but o'k). Then sharpness can be found in the lower left corner of the image (very close to the camera) and on the apparatus and bag on the right side of the image - both elements are located "deeper" on the scene than the "fighters".

Conclusion? IMO lens is "tilted". Speaking another words: in QC field "business as usual".

AshMills, then its even worse (except one like to have lensbaby built into camera).

Marcin 3M: The answer from Nikon will be double golden ring lens series. Canon will introduce "L-extra white with fluoride" series.

Not only Sony. Also Nikon and Canon are in "decentering" business.

Yes, I know. BTW, I hoped for the new qc standards from "master" series. No way, even 24-70 mg samples from dpr exhibits quite heavy "tilt" effect.

Image quality from the lens looks awesome. If the production samples won't be spoiled by QC (alignment and centering) issues, this will be the new standard for quality.

Marcin 3M: Sorry, but Sony looks like Nikon 1 series. Few lenses covering almost exactly the same fls, with minor differences between them, and many bodies (in different colours) with fine features. And user that needs less standard optics has to grab Metabone and Canon...

Considering that I usually carry 4 lenses (in different configurations), from which most are not available in sony lineup, then I would have to put 3 converters to avoid costant fiddling with mounting/removing it from bayonett.

On article Nikon 24-70mm F2.8 ED VR real-world sample gallery (137 comments in total)

I wanted to buy non-vr 24-70 from the first batches that arrived to my country. Tried two, and both were horribly decentered on my d300 (and decentering was consistent between lens copies). I made second approach several moths later, and the lenses were better, so I picked one. The truth about the lens wes revealed after I bought D700 - this one I have bought was also decentered. Fortunatelly Nikon service repaired it, and lens is fine even with d800.
So probably we have to wait for next batches...

Ball bearings did not prevented DP samples from signs of heavy "tilt" of the lens.

davev8: i think Sony should watch this

Dave, they did. They enabled use of third party lenses with new Sony A7.
ijustloveshooting, not only Sony. Decentered Nikon lens is nothing unusual.

Sad. I hoped that QC of equipment manufacturers is improving together with price increase. Apparently not.
And I mean not only Canon - it is the problem with almost all of them.

timotale, don't You think, that grass-sky is almost parallel to the sensor's plane, and plant is in about 2x larger distance than the man?Grass on the left side is oof.
If You still don't see it, look at the second image.

timotale, have You seen this kind of installations from smaller distance? We can see stairs and ladders there. If this plant was not constructed by leprechauns or the person is not a giant - then these objects are not equidistant.

Bildsee, look at the man, the grass and the plant. The plant is sharp, and the man is sharp - and the plant is behind the man. The grass is sharp only under the man's feet, and loose its sharpness towards the left edge.

In reply to:

surelythisnameisfree: Guys - to cover the whole scene with a wide angle lens they have to get pretty close. So much so that the edges are much further from the lens than the centre. With a longer focal length they could stand back and everything is the same distance from the lens.
Think about standing up close to a painting with your nose touching it - You will only see the very centre clearly. Doesn't mean your eyes are no good!

In reply to:

win39: I understand what is being said about curvature of field, but I put in the Nikon D810 as a comparison it seems to be notably sharper in every area of the target. Am I missing the place where you explain what lens was used? I have never found it in your reviews. Is the lens on the D810 a similar focal length to the lens on the Sony? I also wonder whether on the Sony it is field curvature or as you also say it is a lens very close to the sensor. That would be softness due to non-parallel rays which is very different. Soft corners due to field curvature don't happen in a three dimension subject, but inability of the sensor to capture light at the corners because of the angle of incidence is not really recoverable.

surely, haven't You noticed, that most lenses should have rather flat focus plane, and most companies have no problems with this untill less than 24mm?

In reply to:

RichRMA: Wondering about construction. Every Manfrotto I had from monopods to tripods that used plastic clamps or related items eventually broke. This one looks all-aluminum. I hope so.

Digitall, my 055 looks fine too. But small impacts - year after year - on the the clamps caused that almost all of them were broken.
Luckily I got plastic replacements. I'm almost sure that they will last for the rest of life (mine or tripod's).
RichRMA, yes I know that they should be adjusted. But in case of mine the "wing" part was broken.

My 055 from 1994 had all metal clamps. None of them survived. My 190 which is little younger works fine despite its plastic clamps.
