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.

Are use this Lens mount on my new canon M 50, unfortunately the camera was defective but the lense mount did its job.

I use the jeadphones for business amd personal use. I read several bose vs sony reviews anf many bose and sony reviews on Amazon and tried both at best buy. Bose has mucj better voice quality on a call. Sony has better bass but bose has better tonal clarity.Noise cancelling is about the same Sony is $50 cheaper but $50 didnt factor into the equation on somethibg i expect to have for 3-5 years.I dont want my voice to be anything less than crystal clear when on the phone no matter what so the the decision was easy. - boseThe headphones have a sophisticated micriohone array and circuitry thst filter out wind / other noise so the person in the other end hears you like you were in a quiet room.Swiping in the side of the headphone for volume up / down. Forward / backward etc. Wirk good.As many have said the app is klunky but you really only use it whwn settibg up the headpho es first time or when you change the power down timer valie.I love the headphones.calls and to block out noise so i can concentrate better.

Good product. Great price. Prompt shipping. Fits my new Sigma 50-500 mm. Took photos with it. The pictures came up in a good quality.

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

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

Why i first went with the Sigma 35 i have no clue! Ended up getting this one after my sigma took a fall and was getting repaired. I know am selling my Sigma 35m because it can't compete with the canon version. Its worth every penny.
