Very nice quality in small package.

Picked up two of these to go with my two new Hoodman viewfinders. Simple enough to use, and I keep the strap on at all times so I'm ready to attach it if needed.

After putting this on my Olympus M10 Mark 111, I found it worked fine. I could see the screen clearly and read everything. However, most of the time I just hang the Hoodman Loupe around my neck. This is nice to have in your bag just in case you do need to get the Hoodman Loupe on your camera, it is handy to have. You will use it from time to time. Jim, Charlotte, NC.

Works perfectly to hold the Hood Loupe in place while doing video with a DSLR, such as a Canon 5D Mk2. A must-have for doing video to view LCD monitor, but not really needed if you're only doing stills.

You pretty much have to buy this as well with the LCD Hood. I think it has a bit much slack to begin with but that's a quick fix.

I needed help to shoot better video on my Canon DSLR. Sun glare on the view screen and difficulty aiming made it a challenge under many conditions. This set-up solved those problems, especially from a tripod.

Works

Holds the hood-loupe in position when doing live-view and video with D90, D300s, D700, & D3s. Without this you will have to hold this to the rear of the camera (somehow) while you are manipulating the camera controls. If you have a nose like an aardvark then you don't need this; you can hold the hood-loupe on with your nose. If you don't, then you DO need this. Get it.

If you cross the bands over the top of cam, even works with the tiny Canon G16. Just check to be sure the big squeezy nuts don't interfere with lens extension.Several reviews complained about price calling it just a ring with a couple of rubber bands. Very unfair. They're not just rubber bands, seeming very substantial to me--at least as stout as my hiking boot shoelaces with a stretchy, braided, sheath.I also have a Canon 7D for which I use Houdloupe's crane. Tried it on the G16; but the loupe extends vertically downward too far for the little cam. I found a BH offering that might solve that. Haven't called them to ask yet to be sure. It's BH #HOHBST, Hoodboost micro 4/3 adapter. It appears to mount in the hot shoe and raise the crain, mounted in it.I would prefer using the loupe with the crane because of its flip-up flexibility as opposed to the rubber bands. We shall see if the crane will not be too cumbersome with the little G16. Actually, it should provide a better shooting grip with a third stabilizing hand being eye pressure against the loupe's eyecup--not to mention more mass.Convenience? Well, that's another issue. I carry the G16 in a belt pouch and always have it with me. Guess I'm going to have to get a shoulder strap for the loupe and crain, eh?

I bought this for the BMPCC and gave it a 3-star review above. That being said, for the Ricoh GR, it's just amazing. Fits it perfectly and protects it in all situations -- bottom of bag, beach, etc. Can't beat it. If you have a GR, this is a must-have. Also great for iphone/watch/etc in a pinch.
