I was unsure if this would fit the Sony FE 50mm F1.8 lens… fits perfectly and appears to be the exact same lens cap model that lens comes with!

A very good filter. It’s very smooth and has a stopping point. I used this on my sigma art lens for a shoot. No vignetting!

Hab den Filter für mein neues Sigma aus der ART-Reihe gekauft um das gute Stück vor Schmutz und anderen äußeren Einwirkungen zu schützen. Der Filter ist total stabil und wertig verarbeitet. Bei einem Bildvergleich mittels Stativ und 1:1 Konfiguration habe ich keinen Unterschied in der Abbildungsleistung festgestellt. Werde zukünftig nur noch Hoya kaufen...

I ordered the 52mm filter because the 30mm f1.4 sigma lens for sony e-mount cameras has a 52mm thread but after lens arrived, I couldn't fit it on.But after-service support was pretty helpful in telling me this

This camera is an absolute dream to work with. I have Sigma Art primes for my portrait work, and got the rf 24-104 f4 lens for hiking/landscape photos. This has been a seamless tool for my travel photography business.

Let's be clear, this is NOT the best 50mm prime you can get. It's not even great in comparison to them. Arguably, that crown sits atop the new Sigma 50mm F/1.4 Art. Having used the sigma a bit (admittedly, not a lot), it's at least 200% better. Maybe 300% or more, but you'd have to be really adamant about some of the particulars. Make no bones, the Sigma is a tremendous lens. The thing is, it's also an absolute STEAL compared to the former champion, the Canon 50mm 1.2L, $400 more expensive at $1350. If you're following the math, I'm saying this lens is possibly 1/3 as good as a lens that costs nearly 8 times as much, and is already a bargain at that price. There's a reason it's the best selling lens on the market, for any camera system.Yes, your kit lens has 50mm in its range. But F/1.8 opens a whole new world of artistic expression for the beginning or intermediate photographer over the F/5 or F/5.6 that lens opens to at 50mm, and for the price, you'd be insane not to go for it if that even interests you in the slightest. And if $125 is too much to ask for your budget especially if you're a student, get a body $125 cheaper to make room for this lens.

Works very well on my Sigma 17-50 lens. Thank you.

I debated for some time between this and the Sigma Art series 35mm. The color and saturation are stunning with this lens-- it's on my camera now >90% of the time (with 24-70L and 135L as other options). It's fantastic for indoor low-light photos. I have no regrets about this purchase.
