I'm looking at getting a DSLR camera and a couple of lenses. I've pretty well worked through my strategy with the help of the participants in this forum, but one question remains: What is the availability of manual focus aids such as split screen and microprism? I see very little on this topic in discussions and advertising. Is it a thing of the past, given up for matte screens? Is it a high end thing, beyond my reach (I'm in the Rebel XT range)? I've seen the Brighscreen product via their web site, but not in person. Is this avenue worth pursuing? Does anyone use it? I assume from what I've seen, it adds this functionality to the display screen, not to the viewfinder. Any thoughts are appreciated. Why am I even interested? One of the many reasons I've decided to get back to the SLR format is better control over focus, specifically the ability to manually focus when AF just isn't working. I kind of like the idea of a little extra help when I manually focus to ensure crisp focus where I want it.
