The Sony pinch caps seem to hold better than other brands lens pinch caps .I don’t know about canon or Fujifilm but use Nikon and Sigma . Live the new Sigma Magnetic Caps the best . Nikons pinch caps are just ok and the Sigma pinch caps are hard to get on and the square edge on the outside of them let them get knocked off easy . I’ve lost quite a few Sigma Art lens caps by popping off from knocks . The Sony caps hold tight and are shaped not to have an edge to catch .

I don't no what some of you are talking about saying it dose not work with sigma. It dose work with both of my Sigma 70-200mm sport and 150-600mm Sports but the Auto Focus dose not work with I don't mind and it dose not fall off. I love it and it works really well. I just got it.

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!

So far very pleased with this little tripod. Great for videoing while I am creating in my art studio. Which was my intended purpose. My camera has the mount on the bottom side instead of in the center so I have to be careful and balance it properly, but that is not the tripod's problem. I also have a phone mount and I can attach it to the tripod and video tape or do photo shoots with my iPhone. Light weight and small enough to pack and take with you if needed.

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.

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.
