Originally posted by borysr I am really tempted to get one from focusingscreens.com, and wonder, If someone who own it can share thoughts?
what accessories included besides the screen itself ? (I mean tweezers, cloth, box , shims ? )
Do I need to get anything extra ?
also, I wonder if it is microprism area goes black with f4+ or both microprism and split image area too?
Don't want to throw money into focusingscreens and then go back and buy katzeyes one.
Hi.
Make sure the one you buy comes with tweezers that have soft plastic tips so you don't scratch the screen. (Most do.) Also, you'll need a clean sheet of paper to lay the screen on if you need to, and I'd pick up some latex surgical gloves. Where I live, you can get a bag of 20 for a dollar, so they're cheap. I wouldn't use cloth to lay the screen onto, because it might pick up fuzz from the cloth.
Also, if you install the screen and the focus is off, you'll need to pick up a set of shims from Pentax ($6 plus shipping) and calibrate the focus.
Blackout is usually gradual. Even at the point they start to black out, you can adjust the position of your eye when looking thru the viewfinder to compensate. My cheap screen starts to get a little iffy around f5.6, but is still quite useable. At f8, not so much.
I have both a cheap eBay screen and a KatzEye with Optibrite. The KatzEye doesn't black out at all, even with my f8 mirror lens attached, and it's a little brighter. I'd say the cheap screen is about 80% as good as the KatzEyes, and 1/8th the cost. Unless you're going to do a lot of shooting with a lens slower than f5.6, I'd go cheap.
Good luck,
Bobbo :-)
