Thanks for the review!) Love ttartisans and the other chinese brands for their price, quality and the ability to choose bayonet you need.

I have 3 TTArtisan lenses, and they've been great value and very usable. I have the 50mm tilt lens. It's too soft wide open, but I can just stop down a little and add a little more tilt for exactly the depth of field I want - I VERY much enjoy using it. I have been known to use it as a walkaround with just a degree or so of tilt thrown in to make the background interesting. I also have the little Fisheye - and it simply works well. No fuss and a great price. Lastly, I have the 90mm f/1.25, and to be honest, I don't get much use out of it, but I do want to keep trying - it should do amazing things with portraits. Again, like any old school lens, it's just a bit too dreamy absolutely wide open, and the depth of field gets SO shallow that it's a real challenge to use. It's also HEAVY. But, it absolutely does the job it's designed to do and does it superbly considering the price. If you don't mind a fully manual lens, and you pick the right model (some of the 50mm f/.95 lenses just SUCK), these new Chinese manufacturers are making great lenses at very fair prices. The Chinese lens I get the most use out of is the Laowa 100mm f/2.8 macro - I also have the Canon RF L, but the Laowa has a higher magnification and simply delivers more than the Canon can close up.

Looks quite decent for the price. Nice review! Corner problems should be less an issue with APS-C sensors.

I think those soft corners are due to mechanical vignetting and the image circle being too small for 50mm f2 full frame than a lens feature. because its still a relatively sharp lens at the corners but suddenly drops in IQ at the extreme corners.

Like your reviews, incredible hobby for not soviet man :)

Too bad for the soft corners, reminds me of the Pentacon 29. I've been curious to try their lenses, but... well, they haven't answered me yet 😅

Looking at the optical design, I'd say you got the wrong Helios lens. Take a look at the Helios 81N; the groups and the shapes of the optics are nearly identical.

can you please do a video comparison?

Is price point similar to price?

It's to much money for a lens that is only sharp at f 11.

Алекс привет! А я снимал макро фото через макромех и зеркалку

Quality seems pretty damn bad.
