[0.015 lb] As with all Match Technical products, top quality engineering with the finest materials. Large button is very comfortable and using them on all my Fujifilm X cameras.

[0.015 lb] I use this shutter button on my Leica M10-D and it's been great. It's subtle, minimalistic, and functional.

[0.015 lb] Works as advertised - and its red!

[Black] This little add-on makes such a difference in ergonomics. When recording yourself on video, it's so easy to hit the target to get things started. But I'd have to say the biggest difference is the feedback when taking photos. It's much easier to gauge the half-press for the focus on my Fujifilm X-T4. It's much easier to hit the focus on the half press, frame the shot, then full press for grabbing the photo.

The o-ring helps keep things tight. I haven't had it loosen at all yet after 2 weeks...but admittedly, I shoot mostly in studio and do give it a check whenever I start shooting just because some other reviews made me paranoid about it. Haven't had it loosen at all yet. Maybe the other people just didn't tighten it enough.

[0.015 lb] It goes well with the X100F.

[0.015 lb] Perfecto, lo utilizo en mi camara fujifilm y el resultado es perfecto a la hora de disparar, el material es bueno y comodo para el dedo

[0.015 lb] This provides a very nice, smooth release. Only problem is that they are extremely easy to loose when used with the Fuji X-series bodies. This is because the shutter release is used to turn the camera on/off and therefore it's easy to inadvertently loosen the button. Once loose it falls out and is rarely found unless you're inside or notice immediately that it's parted with the camera. May have to resort to using blue Loctite.

[Black] I use it on a Leica M4-P, and am quite pleased with it. No downside to this simple button.
