Camera Viewfinder, Professional 3X Magnification LCD Viewfinder Magnifier for 3in/3.2in LCD Screen, Adjustable DSLR Viewfinder for Camcorder, DSLR/SLR Camera, Camera Screen Sunshade Hood

I was really hoping that this would work for my birding/sports videography work on my FX3 but the mounting screw slot on the viewfinder is about 3/16" too short to mount it to the camera. Another issue is that the mounting bracket partially obscures the cooling fan vent. as I wasn't able to use it I do not know how much this impaired the cooling efficiency. Too bad, this viewfinder has many nice features that I won't be able to take advantage of.

Arrived perfect. Exactly as listed.

I found this item bulky, cheep, and didn't fit well.

Good quality but heavy and not practical to use.

Without a battery grip, this works great. But the adjustable side rails are not long enough to work with my battery grip. So I’m going to be sending it back.

Find another way....

lightweight and expensive is what it is could use optical focus

Very cheaply made and not working from the beginning. The mounting plate does not work with the part that attaches the eyepiece. Feels like dollar store bargain bin material at best. It is a complete disappointment.
