KatzEye Optics: Pentax K-3 Focusing Screens Now Available

Hi

No: I don't work for Katzeye I just like their screens.
Received in my inbox.

Dear Fellow Photographer,

We are writing you today because you expressed an interest in the KatzEyeT
Optics focusing screen for the Pentax K-3 camera. We are pleased to
announce that this model is now available! Thank you very much for your
patience during our development period. A complete description of the new
screen can be found at:

Focusing-Screen--prod_K7.html

Orders can also be placed at the URL above. A brief summary of the features
is as follows:

Original Viewfinder Markings: Viewfinder markings unaffected, all AF points
function and light normally, AF brackets available optionally.

Surely it will be the same as the K5?

Yes...one would think so. I had contacted them to be certain.
Hence the email response.
Never buy anything without the manufacturer assuring compatibility.

Question: Is it worth losing spot metering to have a split focus screen in a camera like the K3 if you have focus peaking already built in?

I would suggest - don't worry about it.

You don't lose it But metering can be compromised some what.
Simply learn how much and adjust according to the lens you are using.
Fast lenses don't have problem.

If the K-3 meters after focus there really should never be a problem.
I would have thought metering should always happen after focus.
Otherwise the meter doesn't know what light it is seeing.

Again...
It's a matter of learning the advantages and deficiencies of your gear.
Then working within these boundaries.

This will never change.

I simply moved my Katzeye from my K-5 to my K-3. Works perfectly.

Also, unlike the K-5, the stock shim works fine in my K-3. Certainly a lot more convenient than making a makeshift shim with Post-it notes like I did with the K-5.

Thanks for contributing Cannikin.
If or When I get a K-3 I have the option.
A custom screen or my current Katzeye.
I have some ideas of what I would like to use.

Agreed but then it is true that, for some, the split screen would be less of a need with focus peaking.
Though it is still an issue very much like EVF vs OVF.

I admit sometimes I wished my view camera ground glass came equipped with focus peaking

Tx, good to have it confirmed that the Katzeye focusing screens for older models will also be compatible with the K-3. Though indeed, it could be assumed to be the case since Pentax lists the same focusing screens as for previous models in the accessory list of the K-3. I have a custom screen that I got for my K-7, then moved it to my K-5, and now I'm looking forward to migrating it to the K-3 as soon as I get it.

I never quite understood where you put the shims. Are they placed on the stationary part of the focus screen housing? Or do the go on the part that swings open? Do you just place it on the housing?

Confused......

Shims go between the focusing screen and the pentaprism. The whole purpose is to adjust the spacing between the lens and the screen in order to match the plane of focus. If the screen front focuses, use a thinner (or no) shim to move the screen further away from the lens. If it back focuses, use a thicker shim to move it closer.

Putting it on the swinging part would do nothing because it would be on the outside of the focusing screen assembly and thus not alter the position.
