The only fellow on KZfaq who makes reliable honest reviews. Thank you.

i remember when the original 50mm ART came out, man was that an eye opener. i had paired it with my trusty 6D, holy moly i remember thinking it didnt get any better. glad to see it has indeed gotten better!

As ever Dustin, an excellent review! This 50mm Sigma is certainly a lot better in regards to sharpness and bokeh, however, the original Sigma Art lens had virtually no distortion at all, indeed I used it on many commercial jobs where buildings were featured, but why Sigma couldn't replicate the near zero distortion for this 50mm and the new 85mm is puzzling. But all in all a fantastic performing lens at the price!

Been eyeballing a solid, affordable 50 as a friend for my 24-70, cool option here!

Another excellent review, Dustin. I'm now thinking of selling my Sony Zeiss 55mm 1.8 and getting this one. Thanks!

Great review and beautiful shots!

Thank you ever so much for another great review, very much appreciated.

just waitng the sony gm 50mm 1.4 :)

Thank you for these great reviews. Have you considered adding a section that would go over the rendering and micro contrast for primes, as part of the review? That would be much appreciated.

Great review. I'll wait for the sigma 50mm F1.2

Seems to be a top contender going forward, as the DSLR versions of this were already well received by many photographers. Looking forward to the point in time when all these 3rd party lenses get a chance at competing with Canon's RF glass.

Should I keep my samyang 50mm 1.4 ii or get this one 🤔

Dustin, thank you for the very comprehensive review. I'm a big fan of your testing methods and expertise you have acquired using lenses in your possession. I have been doing a lengthy research for 50mm and 35mm lenses and finally decided on going with 50mm f/1.4 and 35mm f/2. Interestingly few websites, namely Lens Tip, Optical Limits, and EPhotozine are using Imatest and Sony A7R 2or 3 cameras to test the lenses, Because of that their tests are comparable. Still, I have found that some of their values vary quite a bit. I understand that there are variances between lenses but Sigma supposedly tests each of their premium lenses to be within specs. I'm not sure whether you came across something similar when the test values would differ considerably. I wonder whether this could be attributed at least partly to a test shot that is not critically in focus.

How is this lens on the fx30 or other apsc cameras?

Great video. I know you used to use Sony Zeiss 50 mm 1.4. How do you think this one compares to that one? I have the Zeiss and am perfectly happy with it but the photos from this one look very tempting.

Was hoping this new Sigma 50mm will be the best for astro, but at least based on other reviews it doesnt handle CA very well. Looks like I will have to wait for the new Tamron 45mm

Thanks for putting out that review. Excellent work. The distortion and the CA is really not my cup of tea. It should be better than that.

Seems like everything Sigma puts out these days are top notch.

Good job as always!! God bless

I’m confused I have a sigma 1.4 for Sony emount. What is the difference

I think the best option here would be the new Sony 50mm f/1.4 GM. As for the f/1.2 GM I would rather jump to Laowa 35mm or 45mm f/0.95 for a notable upgrade in bokeh and low light performance but of course no autofocus.

I’m quite puzzled tbh, saw a review from Gerald Undone in which he was complaining and showing very extreme chromatic abberations, which really put me of this lens. He even had a talk with Sigma and they seem to think that this is normal….

I like my Sigma 65mmF2 DG DN lens so much that this one will not be bought....😉 Thanks for the awesome review as always

I want to know winer of sigma 40mm vs 50mm dgdn.

Is the video sped up or I've had too much coffee?

The uba expensive, if excellent, Sony G master has strong competition, certainly on a value for money basis.

Please bug them for a DN 70-200 too.

Focus by wire is truly evil.

That "bokeh"🤢😭😭😭😭😭😭😭😭

I think this is the one. Half the price of GM

THe best bang for the buck 50mm is the Zeiss 55mm F1.8.

Canon is the worst

Too many introductory adverbial "And so as you can see..." repetitions when, actually, none is needed, and all should therefore be omitted. William Strunk, Jr.'s Elementary Principle of Composition No. 13 is, "Omit needless words," and "As you can see..." is entirely needless. What's more, endless repetitions of an idiosyncratic phrase gets to be tiresome and boring. "As you can see, this lens is..." can and therefore should be shortened to "This lens is..." with no loss of clarity, emphasis, or meaning, and no little savings in time.
