no i didnt mean photo is soft...your 85DG DN lower left corner is softer than other corners of 85DG DN.Also fill extreme corners with texture and you'll see more pronounced softness on the lower left corner.

I don't really want to continue this discussion ... we all have different standards obviously and for me this kind of difference between corners is acceptable. Is it flawless/perfect, of course not. Is it soft, also not.
The thing is, I'd have to call all my lenses decentered (my 135 GM even more so) if the threshold is already met on the Sigma. I'm also testing handheld, so there is some variability to it, even though I try to limit it and do repeat some tests. Since you have still not provided your 135 GM samples, I also still don't know what threshold you are talking about.

Anyways, I wish you a good life without me in it. Bye!

Hmm, this is actually funny.
Maybe my eyes are wrong though:
can anyone tell me if this is soft - (lower left corner):

To make it easier, here's upper right corner for comparison:

Take a look please only on the left side of the photo, as the right side is Samyang.


I don't see softness is the lower left corner.

Thanks guys, I thought I was losing it for a moment .
I mean the corners are not identical, but not soft either .


I can see a slight difference, but I would not call the lower left corner soft.

the texture is not is extreme corner, i call it mid corner, once he filled the extreme corner , he will have clearly softer corner,,,sigma DG DN samples i've seen so far are all decentered to a degree unfortunately.

i'm sorry to see you bothered that quickly, wish you big luck in life, you really need it
here's the gm sample , these are the very extreme corners, not mid-corners like your samples.

That seems like a pretty big assumption. Truth is we don't know what those very last pixels in the corner would look like on this lens. For what we can see the lens isn't soft right up to the very extreme corner. I am not going to assume that it gets soft in the small amount of corner not tested, and to assume decentering we would have to assume that such softness doesn't occur in the other corners. Suffice it too say the pictures presented do not show strong evidence of decentering, but do not rule out mild decentering that affects the extreme corners.

Decentering is of course a relative issue. If we look hard enough with a camera with enough pixel density we will see some mild decentering on many lenses. The question becomes how much decentering are you willing to live with, not is a lens totally devoid of decentering. Personally for this lens and for the uses I would plan for it, this test would indicate to me that any decentering that does occur would not be of a concern to me, YMMV.

As Steve noted you are assuming here and have NO DATA to support this claim.

hey dear good character,

i've two decentered sigma 85DG DN i provided photos like below, both of them has right-upper corner softness, i can clearly see clear softness on right upper side with my landscape tests at F1.4, these lenses are decentered, sad but true,
https://imgupload.io/image/Rfko
https://imgupload.io/image/Rua1



You provided photos from your 85DG DN and even the photos are from mid-corner not from extreme corner, your lower left corner is clearly soft and your lens is also decentered, in extreme corners it'll be more obvious.

Here is the guy who reviewed his 85DG DN also reports decentering,
https://www.cameralabs.com/sigma-85mm-f1-4-dg-dn-art-review/4/

Also a youtube review i watched had clearly decentered 85DG DN , i can find that video if you want.

Thanks.

for those interested in both GM135 and sigma 85DG DN, here's my unscientific test,

center area comparison,
https://imgupload.io/image/sigma85gm135-center.Rw8N

mid-corner area comparison
https://imgupload.io/image/sigma85gm135-corner.RzWM

sharpness results are consistent with all photos in favor of GM even on 24mp sensor.

Probably would've made more sense to compare them at the same aperture.

Also in MF since the A7II isn’t exactly known for its AF, especially with 3rd party lenses.

Anyone shooting this 85? Not many love... does people went with the 105 instead the more portrait oriented 85?

No, not really. And the comparison is invalid, anyway.

I'm still using mine, but it's winter season now around here so most of the time I spent indoors, where I find 85mm too tight in most cases to take an interesting photo (well I also did another semi-outdoor decentering test after that fruitless discussion in this thread, but that doesn't count as shooting I guess )...
I think 105 is not really an actual rival given the size&weight difference, for me at least.
Sigma 85 dg dn for me is the best overall package for that focal length available in e-mount, so I don't think I will be leaving it soon (unless I fell a strong need to downsize my kit and decide to replace both my 50 and 85 with the new 65 ).

A couple from the last walk I took it on:

yes infact you cant compare at all..Sigma is really excellent only in center - a small circle,, little bit off center , closing to corners, resolution drops signaficantly never satisfied, and that distortion without correction makes you look 10kg less , lol.
GM135 on the other hand, center to corner, AF to distortion, a masterpiece.

Completely not true.
You should have a defective lens, or something else...
