I've been having increasingly worsening vision problems for the past few years and was recently diagnosed with a vision disorder that makes my eyes slow the change to differing light levels. This has left me with a couple issues that are making it increasingly harder to frame and shoot my cameras (D7000 & D600).
The first is that I can't see live view in daylight -- it all looks completely washed out. Plus, I find it nearly impossible to fine focus manually using live view. I know that there are some hoods for use with the LCD -- but I wear glasses and have never had much luck with any hood I have to use with glasses.
What I'd really like is some means of using the viewfinder. With it, I can take off my glasses, and by adjusting the diopter, I can get a reasonably in-focus view. However, the image is so small, I have a hard time with fine focus of the small image. I know there are a couple of magnifiers that fit on the viewfinder (and I have the DK21M), but they tend to crop the image significantly and/or only provide a center focus magnification.
So, what I think I'm looking for is something that magnifies the entire viewfinder, that you can hold up to your eye, and has a good diopter adjustment.
A couple of other points: I want something that I can use w/o a tri/mono pod, and I'd like something that I can use in the same manner as the viewfinder, as I like the additional stability I get from the camera resting against my faces (vs holding it at arm's length to see the live view screen).
Any suggestion here? I'm also not looking to spend hundreds of dollars and would prefer something that works on both a D7000 and D600.
Thanks in advance!
