Zyyini Camera Viewfinder, Professional 3.0X Magnification LCD Viewfinder, for Camera Camcorder with 3in/3.2in Screen SLR Viewfinder

Works well at keeping light out but makes my compact camera (Cannon EOS M) as bulky as my SLR. I'll keep it for when most of the expected shooting is not in bright sunlight, and I want to use the compact.Would really like to find one that collapses but the "folding box" sunshades don't work at all for me.

This is very well built and is done with hard plastic. However, I could not see anything when I put it on the highest diopter. It is rated for +3 to -3. As it is a hard plastic, one could file off some of the plastic carefully bit by bit till it fits your eye strength (if it is - if It is + you could add a frame). It would be nice if they provided a larger offset for the lens as some others do. However, the reason I did not do it is that the eye cover does not fit my face it is way too big for me and thus even if I would make the modification it would not fit properly for me. I have not tried the adhesion and would not do it as a flip screen would no longer be able to be closing onto the screen. For those that have a different face form and the diopter calibration works I think it is a good value despite being big.

Work great on my Canon t6. Been eyeing it up for months. Now that I got it I wish I got it sooner. Great for wedding.. family events... you name it...
