EVF4RVW Viewfinder with 3.5" Retina LCD Display, 960x640 Resolution

Great product

I work in the professional film industry with lots of high quality and very expensive equipment (Film, RED, ALEXA etc). For my own personal low-budget projects I have recently been using the Nikon D800 in a Run & Gun style for small projects and documentaries. This EVF is extremely useful for focusing and getting spot on exposure with a camera that has limited dynamic range and relatively lousy lenses (for motion picture anyway - great for stills).I am happy with the price.I am extremely disappointed with the engineering as far as the strength of the body especially the 1/4-20 female jacks. It is like an afterthought. Attached to the body with very tiny screws (look at the picture carefully). If you tighten an Israeli arm or ball-head with just a little too much force those screws with shear right off. Secondly the battery plates are weak plastic and the Sony batteries I have been using are loose on the plate, I have to tape it up or use small bungees to keep it tight.Finally Cineroid customer service is NON-EXISTENT. I have been trying for months, I cannot find the battery plates anywhere and they have basically told me good luck (chum).Well Good luck to you folks out there. The product has amazing potential and I like it very much except for those annoying issues.UPDATE: This is an old review I posted for another website. Everything above remains the same, except I have moved on to Sony mirrorless for my video needs.But I want to emphasize that ***CINEROID SUPPORT DOES NOT EXIST***

It does everything I need it to, the display is excellent, and the features are amazing. I must say it's hard to justify the price tag though - one could get a 60" HDTV with better resolution for less. You're paying for the SDI input and it's hard to not feel robbed. Two things - the focus peaking function is basically useless - it shows thick red lines that aren't really helpful for critical focus, also, I REALLY wish it had HDMI OUT! I bought it for the Blackmagic Cinema Camera since it uses SDI cables, HDMI would help a lot in that I could output the picture to a regular monitor.

Does everything you need it to do, IMO is better than the Alphatron. The software and interface in particular. The Alphatron has a lousy OSD and is a larger, heavier unit. The Cineroid is a little delicate like people say, but if you don't throw it around it's going to last awhile.
