Manual Focusing tips

I have just been looking on Katzeye website and Ebay. Big difference in price 105 USD to £13.40. Are they different technically does anyone know?

The cheap ones are rubbish, they blackout after f8 making the screen unusable.
That's what I found anyway and as I do a lot of macro it was pointless keeping it in the camera.

They also list for the K10D and K20D on http://www.katzeyeoptics.com/cat--Pentax-DSLRs--cat_pentax.html

K20D uses the same screen as the K10D, by the way.

Changeable by whom? By oneself! Here's that video again: http://uk.youtube.com/watch?v=YqZCjT-jr1s

Katz Eye screens are expensive but one is very well worth owning if you want to use manual focus lenses, or just have assurance that AF is working.

A statically charged brush is handy for removing dust from focusing screens. There is the electric Arctic Butterfly (that is supposed to be for sensors), or I'm sure you could use a more ordinary (but good quality) camera brush and charge it by rubbing it on something.
