KatzEye and K-5: does it need calibration?

I have a question for those, who are using KatzEye with K-5.

I am thinking about getting KatzEye for my K-5, however one thing makes me warried.

When I had KatzEye with K20D, I had to calibrate it. Calibration was easy, because at that time I lived in Melbourne and had zero problems getting calibration shins from CR Kennedy.

Now, however, I live in place where I doubt that I will get calibration shims easy.

So, my question is: did your KatzEye+K-5 need calibration for precise focus?

My k20d needed no shims but the k-5 does. I didnt worry why, just broke out the yellow sticky pads for some cheap shimming.

I installed KatzEye on my K20D and I was lucky - no shimming required. I presume that you are aware that KatzEye will install, shim and test for you?

I had installation of the screen in my K5 done by KatzEye (who did a great job). And yes, it did need different shims.

my stock shim was too thick for the katzeye so i ordered a full set from Pentax and used one two sizes thinner (cant remember which number specifically).

Thak you for your responses.

Unfortunately it seems that KatzEye and K-5 need calibation and basically that a no-go for me

Hi
My K-5 with Katz most definitely focuses perfectly without shims. Transplanted it from the K-7 (which also was not shimmed). Just installed it tested it and it works spot on.

Greetings

if you think about it, using a split prism type screen is giving you better accuracy in focusing a very shallow DOF; this is a level of precision beyond what the stock screen can offer. The factory installation of the stock screen permits much more "slop", which is revealed with a screen upgrade. So, the issue is nobody's fault, it is just whether or not the factory installers "guessed" right with the original shims.
With the Katzeye (or any other split type screen), you want to get the shimming exactly right because if you are even slightly off, you defeat the purpose of having such precision. I have thus come to conclude that anyone who upgrades their screen should expect to need new shims to get it right.

personally, i dont find the swap out to be difficult, but every time i remove and replace screens and shims, i introduce more dust and risk dropping or scratching the mirror or screen, so it is not my favorite thing to do. good luck!

It's not a problem for me to replace shims. I've done that before on my K20D.

The problem is that I don't really know where to get those shims.
