Katz Eye Split prism
I find that the green hexagon usually comes on, stays on, then goes off, as I move the focus ring. I think this may be because the focus sensor picks up other objects in it's range. Say if you want focus on the *front* of one particular apple on a tree, there may be other things (twigs, leaves, othe...

Tommy Cooper would have advised... Don't focus on the *front* of one particular apple on a tree then! :shock: :mrgreen: :wink:

Katz Eye Split prism
As a rule, the green hexagon comes on and stays on if the split screen suggests that a shot is in focus, which I guess is what you would expect if everything is working OK. For me, the big advantage of the split screen is not that is makes focussing more accurate - but that it makes it much faster ...

Katz Eye Split prism
I have a KatzEye on my K20, and it's a great improvement for manual focussing. It doesn't affect autofocus, but as andrewk says, it affects spot metering. Centre-weighted and 'green' metering seem about the same.

Katz Eye Split prism
One thing you should be aware of when fitting a new focussing screen for accurate manual focussing is that you may also need to fit a new focussing screen "shim" as well. The "shim" is a little washer type thing that ensures that the focussing screen is positioned at the correct distance from the le...

Manual focus lenses on Pentax K-5 II
I'm a bit confused with Steve's last comment. As far as I understood AF in a DSLR it uses a separate path to an AF sensor normally situated at the bottom of the camera under the mirror and is not affected by the focus screen. I thought the focus screen is only required for manual focussing and even ...

focus adjustment k10d
Hi all, can I ask the really thick question here? (at least I admit to it):lol: With the K10D I didn't realise about all this BF type of issues, do they apply to just the autofocus mechanism and focus confirmation or what appears to be focused in the viewfinder when using manual focusing? For ...

K110D AF Back Focus - All Lenses
Hi Team! I used both the Nikon (booooo) and Pentax (yea!) focusing charts to check out the Auto Focus on my K110D. Used a whole whack of AF lenses, including my 31mm Ltd. The tests were shot initially wide open (Max aperture) on each lens. All results had major back focusing issues which on...

K110D AF Back Focus - All Lenses
AF accuracy has nothing to do with the focusing screen. In fact AF still works even without a screen fitted. You need to examine the photographs rather than the viewfinder image to check AF accuracy. If it is consistently wrong with all lenses, you may be able to fix the problem by altering a "se...

K110D AF Back Focus - All Lenses
Pete, Thanks for clearing that up! Hey Don, Pete says I can run around blind with no screen and the camera on AF - that way all my shots will be surprises (and probably better than what I'm getting when I actually try!) I'll save that for when you come down. You like stuff like that. Other...

black spots in viewfinder
The shims do affect focusing, but only manual focusing - how focused the image appears on the focusing screen. The camera's auto-focusing is unaffected by anything you do with the screen. Spot metering is a mode of the light meter. It can be affected by the focusing screen, but this has nothing t...

Exposure problems with new focusing screen
Were you using spot metering? I have only heard of problems with spot metering and split screens, not with specific lenses. Mine seems to neter fine with the katz-eye screen I bought from axl. Best wishes, Kris.

Installing Katz-eye screen.
Hi all, I am planning to purchase a katz-eye screen for my *istDL2. The firm makes it for my camera and what read from their faq's is that there is a very good user manual provided for installing this screen. The question i have is: I there anyone here who has actually done this by experience and ...

Installing Katz-eye screen.
I have fingers like courgettes, and I fitted a Katz Eye to my K10D. I was terrified, but it was very very easy.

Installing Katz-eye screen.
It is quite easy. Try to wear disposable plastic gloves so you dont get a fingerprint on the screen or mirror. I find a wooden toothpick quite good for manoeuvering the screen into the carrier, and a pair of tweezers for holding the screen tab. If you can get plastic tweezers, all the better. ...
