I have a few more questions. I see in some of the threads about focusing screens that meetering will be affected. Can that be a negative effect when using AF lenses.
I have also seen metioned by some that flash is behaving different. This worries me a litle as i use flash very much.
I do have to consider if its worth putting a splitscreen in the camera, because i use AF lenses and flash more than i use manual lenses.
So...im not really sure what to do
Focus screens do not affect AF. Split prisms are known for affecting Spot Metering in particular. The Katz Eye people post a warning concerning the use of their screen and Spot Metering at their site.
Only you can decide if you need a split prism. Split Prisms are a boon to those of us who have fast, older galss and want to enjoy it. That said, Split Prisms in no way slow me down from using my newer, AF glass, nor flash for that matter.
Like everything else in life, choices come with consequences (costs)--only you can weigh the various costs vs benefits and decide accordingly for your situation.
So gather all the facts and make the best choice you can--good luck.
