I use this particular Viewfinder for DSLR films with the 5dmk2 and MagicLantern in daylight or sunlight or strictly speaking, almost always, when it comes to the matter film. Finally really sharp questions and recognize all of the settings just fine. The results are technically better. The Committee due to incorrect exposure or blur is reduced to almost zero. The assembly with the adhesive frame works, but of course not for eternity. For me, the initial installation, with careful design, held around 1 year. Then I renewed with double-sided tape, no big deal and work. Yes sure, there are also Viewfinder with base plate. Basically, a good idea to me is the mounting plate but too small or with use of heavy equipment such as the 5dmk2, with a correspondingly large lens, not stable enough. What good is the best stable video tripod with large mounting plate when the plate for the viewfinder does not carry the camera weight. There are shaky shots. The frame serves as a screen protector. All good.
