Sigma 322965 85mm F1.4 DG DN | A For Sony E, Black

Product Information

The Sigma 85mm f/1.4 DG HSM Art gives minimal chromatic aberration at f/1.4 and shows minimal (invisible to the naked eye) barrel distortion. In my experience, the lens reaches its ultimate sharpness between f/2 and f/5.6. One last point that we discovered during these tests. One of these lenses is not a true 85mm. Basically, the Sigma is visibly longer in reach than the Sony, this isn’t necessarily a pro or a con just something to keep in mind. Minimum focus distance (sharpness close up) as a long time GM85 user, i can definitely know it's sharpness at F1.4 and i could never seen similar sharpness on Sigma F1.4 shots available on the net so far. GM85 at F1.4, in terms of sharpness, winner.

lets review... YOU started this off by specifically claiming that eye-af doesn't work, and you still haven't posted any proof of that. The official minimum focusing distance of the Sigma is 85cm although we were able to focus as close as 78cm. The Sony’s official close-up distance is 80cm and that is exactly what we got in our test. The macro magnification of the Sigma is only 1:8.4 compared to 1:7.6 of the Sony – both considered low but quite common for this type of lens. All we've had till now is the model shots from the Sony event that you attended. I'm sure I speak for many forum readers when I say we would appreciate a gallery of real world shots taken by you guys, like you've done here for the Sigma and other lenses. We didn't experience too much "hunting", either in good or bad light, with the lens accurately focusing almost all of the time. It's also a quiet performer, thanks to the built-in HSM (Hyper Sonic Motor), which makes this lens quite well-suited to video recording.In general autofocus is fast and reliable. Eye AF works like a charm on my a7RIII. For portraiture I have absolutely no complaints. The day you find a lens where the stars in the corners are just as round and sharp as those in the center, and the stars don't have red and blue halos... that's the day you've found a good lens. However when you are in the market for a 85 mm lens with very fast AF this will be the better option. Great review. I just recently bought the Viltrox MkII and am very happy with it, except for the lens hood, which is a pain to attach. The beauty of third-party manufacturers is that they can provide lenses for all the different brands. The Sigma 85mm f/1.4 DG HSM Art was specifically designed for full frame DSLRs. As a result, it is compatible with a variety of mounts like the Canon EF models (like the EOS 6D, EOS 90D, and EOS 5D), Nikon F models (like the D750, D6, and D850), the Sony E, and Leica L.

Is it a fast (responsive) lens, or rather slow because of the large optical groups that have to be moved ? Is AF with zoom lenses faster or slower ? At the center of the frame wide open at f/1.4 the Sigma is actually very sharp, sharper than the Sony at f/1.8. Both improve somewhat when closing down (the Sony more than the Sigma). Even mounted on a 20MP Nikon D5, the results were better than a 42MP Sony A7r II with a Zeiss Basis F1.8, which is no mean feat! His expertise with equipment doesn’t end there, though. He is also an encyclopedia when it comes to all manner of cameras, camera holsters and bags, flashguns, tripods and heads, printers, papers and inks, and just about anything imaging-related. Pincushion distortion is a glaring issue with the Sigma 85mm f1.4 DG DN Art. The above image was shot with the Sigma with lens distortion compensations disabled. The pincushion distortion is rather significant. This is problematic if there are lots of straight lines within your frame. There’s noticeable vignetting towards the wider end as well. Be sure to enabling lens distortion compensation to remedy both issues. They can also be rectified during post-processing if you’ve been shooting with distortion compensation disabled.To decide between the two you should decide whether the higher weight and higher price are worth the difference in bokeh rendering. I own quite a bit of Canon-L glass. I have yet to find one that's actually very good at any of this. By the time you stop them down to where they actually work reasonably well, you've lost all the advantages of the wide aperture.

An 85mm f/1.4 prime is a classic portrait lens. Some people may find that they prefer a 50mm or a 105mm instead, but it is a pretty safe bet to consider an 85mm if you do any type of portrait photography. Families, kids, couples, fashion, you name it. Having an 85mm prime is a good idea. Portrait Photography no, that's not correct, e-mount adapters don't always cripple the af modes... the mc-11 in particular comes to mind. Interestingly my comparisons revealed the lens displays greater pincushion distortion than Sigma’s 85mm f1.4 DG HSM Art so some users may want to apply a small amount of manual distortion correction in post.

User reviews

Also, when Sigma “goes for broke”, and creates a lens like their DSLR f/1.4 primes, or their Sony E-mount 35mm f/1.2 DG DN Art, the results are, well, massive. Because of this, I was fully prepared for an obnoxiously big and heavy 85mm f/1.2 prime, or even an oversized 85mm f/1.4 prime. Sunstars have never been high on Sigma’s priority list and the Sigma 85mm f/1.4 is no exception. The eleven not perfectly aligned aperture blades result in rather fuzzy sunstars with 22 rays. This is a portrait lens though, so complaining about sunstars is a bit unfair. Coma

Honestly? If you really like 85mm, whether for serious portraits, low-light journalism, or just casual artistic imagery in general, get this lens to go on your Sony E-mount body, or your Sigma/Panasonic/Leica L-mount body. You won’t regret it. it is important to manual focus on test charts etc. your eye will find the best result - which is indeed, important for the dprev image quality test. From what I have seen here the Zeiss Otus delivers similar outstanding results, but I`m quite sure I will be able to use it untill 2050 and maybe longer… 😉 The rumored Sony 85mm f/1.2 has zero appeal to me, no matter how good it’s likely to be optically, because of its probable size and price. (I could probably buy BOTH the Sigma 85mm f/1.4 DG DN and the Sigma 90mm f/2.8 for less than what the Sony 85mm f/1.2 will undoubtedly cost). Based on this I really can’t say that the Sigma is much sharper at infinity. Wide open at infinity it has a bit less glow than the 1.4/85 FE, but furthermore I don’t see much difference.Between the two, the additional light capturing capability of a low f-number lens is either lost, or image quality is severely impacted. However the Sony has even nicer bokeh to my taste, with some undercorrected SA and less optical vignetting. In terms of sharpness the two lenses are very equal near infinity, at closer distances the Sigma seems to be a bit sharper. The Sigma seems to have an edge regarding AF speed, but I did not have the chance to compare them myself. The Sony seems to be significantly more flare resistant though. In terms of resolving power, it’s one of the best choices that you can find on the market. It can even compete with such alternatives like the Zeiss Planar T* 85mm f/1.4 Z F.2.
