[Red] This button is not only a fun character to bring to serious photography but it is well designed so that every press is soft and brings added satisfaction to pressing the shutter.

[Red] Convex soft press proponent here because why would you want something that effectively repeats what your shutter release does? I have two, one for my Leica M10-R and one for my Leica M4 and it's so very perfect for both. Having it on makes me super confident that I'm not over pressing to the point of camera shake and thus increases my confidence and concern over a shot, which translates to more shots!

[Threaded Screw] Works as described and is an essential upgrade. No more fidgeting around to get to the too-small shutter-button. Offers a better touch and shooting is more steady. Looks good, too.

[0.03 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.

[0.03 lb] This soft shutter release has a great feel on my finger and enhances the usability of the shutter on my Fujifilm X-T4. An already great shutter on the camera is made even better with this device. Plus, I've not experienced any of the issues with the soft shutter coming loose that were mentioned in reviews of other devices - of course, I'm a bit paranoid about losing it, so I do check it periodically. Plus I think the red color looks great (silly perhaps, but true). Highly recommended.

[0.03 lb] Love the feel of this on my camera. No guess work. Perfect.

[Red] Nicely made, quality soft shutter release by Match Technical. Anti-slip rubber o-ring prevents the button unscrewing. This size seems ideal for the Fuji XT-2 as it does not interfere with the camera's on/off switch in any way. I purchased the concave button which works great for me (especially effective when wearing gloves) I believe that they also make a convex version. Great product which enhances the already excellent ergonomics of the XT2.

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

[0.03 lb] I use it with my Fuji X-T20 and I would say that the button is a bit large in diameter. Its around 10mm. Half size would fine. No problem with shutter release, but still, it hits the shutter speed dial.
