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.

49mm is the go-to size for Sony NEX lenses, the kit zooms and the 16mm, 20mm, 35mm, 50mm all have 49mm threads. This is a well-made replacement.

Got this as my 1st wheel for racing F1. Love the easy set up and use just wish I had more time to use it more often!

Very nice lights.4 Stars because the connection box is too BIG.

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

Light works well but it small. I was hoping I would be able to mount my Sony a 6400 in the center but it’s too small. You would definitely need a very tiny camera. I have my camera on it’s own tripod behind the light in my photo attached. Light has a nice brightness, multiple settings and does the job.

Good, solid mount.4 stars only as there is room for improvement.I need to use a pair of pliers to tighten the "T" bolt.If tightened by hand (and I have a very strong grip), it still allows the camera to tilt over.
