Does anyone use split-focus viewfinders on cameras with AF? I used to use one on my old Canon FTb film body, and I quite liked it.

Is it worthwhile on new cameras? Can you actually put them in aftermarket?

Split focusing screens are rad, and are REALLY useful if you use manual lenses, but the Chinese ones suck, and good ones (Katzeye, for example) cost a shitload of money. Also, they fail at apertures smaller than f/5 (thus, they will render lenses like 500/8 totally useless)

Reading up on this myself now, the Katzeye ones do sound really fantastic, albeit expensive, but I'm wondering about this "blackout" part.

So basically, if I use anything smaller than f/5, I can't see shit?

I just had a look on their website at the one for the Nikon D80. Apparently their 'Plus' series is OK up to F11.

No, you can still see the matte part of the screen. Just the split image and/or microprism collar black out.

Also, it's only the maximum aperture of the lens that's relevant to the focusing screen, since focusing happens with the diaphragm fully open no matter what aperture you're shooting with.
