Might as well start a separate thread now that the lens is officially released.

Received mine today and took the obligatory pet shots as it was already dark when I got home. It is a big lens but feels lighter than the Otus and pairs nicely with a gripped D810. I think it will carve out a nice niche in between the Nikon and Zeiss and adds the benefit of AF. So far I am very pleased.

Thanks for starting this thread. Hoping to see dozens of pages of glorious photos in the future.

I took about 15 shots with it last night so not enough for a fair assessment. Initial impression was that it was on par with my 35 art on my D810...in other words I didn't find it lacking. Hit my focus point and it didn't hunt. Going to do a little further testing with it on the D5 this weekend and over the holidays.

My 50mm ART is certainly a step up from my non-ART 85mm sigma so I'm hoping this one will be similar.

Glowing review from lenstip: http://www.lenstip.com/491.1-Lens_review-Sigma_A_85_mm_f_1.4_DG_HSM_Introduction.html

The only thing they didn't like was vignetting wide open. They say that aberrations are well controlled too which is nice to hear.

For comparison:

Non-ART sigma:


ART:


Looks like Sigma has done it again with the ART series.

Serious? What fast prime doesn't have cats eye bokeh? This is getting ridiculous... unless your joking...

that doesn't have to do with the lens. It has to do with the object in the image and its relation ship to the center of the film. Re cat's eyes

I agree with you completely.

I did notice, however, that lenstip saw fit to comment on how significant the extent of the cat's eye truncation is ("a bit worrisome," in their words), especially given the generous dimensions of the lens.

Cat eye bokeh is a mechanical vignette, which is why it reduces when you stop down. You're literally seeing the limitations of the lens body's ability to bring light through it.

I don't think I've ever seen a fast prime lens that didn't have this. My 135L has it like no other...but that lens is considered "legendary". The only way to make this lens have less cat eye is to make the body larger...I think it's safe to say the same people complaining about the bokeh shape would be the first to complain about the size and weight of the lens. Haha

Cats eye happens because of this, see figure 2 here:

http://toothwalker.org/optics/vignetting.html

It is UNAVOIDABLE. Unless of course you have a front element that is so huge that it makes the lens unusable.

Looking at lenstip, the cat's eye extent wide-open seems comparable to the Zeiss 85/1.4 lenses, but noticeably more than, say, the Sony 85 GM (77 mm filter).

Here, scroll to the cat's eyes:

Again, not something I personally care about.

Some shots I took with the Sigma 85 1.4 Art, honestly, if you really care about the contrast of an image and vignetting, this Sigma 85 Art is very contrasty and controls vignetting pretty good, other than that, the 86mm Filter Thread and the huge size of the lens may be a turn off for some.

Did a youtube video putting the Sigma 85 Art against the Nikon 85 1.4G , seen here, thanks!

The Sony 85GM is very good in this respect. Only in the very far corners you can see it a bit, compared to the Batis (similar to the Tamron 85):






Dustin Abbott in his review says the Sigma to be no true 85. It was significantly wider than the Tamron 85, for example.

I saw Dustin's review, it was very good. I don't think it was a significant difference because I asked him if maybe the Tamron was longer than 85mm and he confirmed that the Tamron is probably and 86-87mm and the Sigma is an 83-84mm when compared to a Canon 70-200, which I believe may be a little longer than the focal length markers indicate. I'm really enjoying the lens so far and the focal length difference is very negligible in actual use so I wouldn't have even thought it was "short" if I wasn't being told/shown it was a little short of 85mm.

Talking about a few mm seems pointless. All lenses focus breathe and comparing to a zoom which focus breathe even more seems pointless.

The nikon 70-200 VRII becoming at 135mm at close focus - that is something to care about.

Here the difference was there at infinity, too. So not related to focus breathing at MFD. I am not concerned about the Nikon 70-200/2.8 breathing, never bothered me. But that is of no concern since I will sell it anyway. Like to use primes more and will exchange my Nikon gear with Canon 5div.
