S-Type focusingscreen

I have a S-Type focusingscreen once bought for K-5. I no longer have the K-5 and would like to use the screen in my K-30 instead. I've tried twice with no luck and in recent attempt I got few fibres on the screen. I'd like to keep it as clean as possible so Im here asking for clearer directions for this specific combination (S-Type screen for K-5 to be used on K-30).

Hmm?

You mean K30 screen dimension is different from the K5's?

The screen fits K-30. Sorry I didn't mention that. Question revolves the shims, how many to use - and which ones, there are the normal and a "black" one, or if they would be sufficient at all. I'm asking because I do not want to fiddle too much as that increases the risk of getting dust and whatnot.

I have a focusingscreen FSB in K100DS.

The number of shims is trial and error, using the calibration method described on their website instructions. (Photos of a ruler at an oblique angle.)

I had a problem with the instructions - somehow I got the orientation wrong so the screen was upside down. Does not work properly. (The problem was that the pictures had the body upside down.)

Then I went back and changed it. I needed the stock shim and two of their clear ones.

The job is tedious and leads me to get a bit shaky - which is not normally a problem.

Ok, i do not wish to write down a full detailed description. So i'll put it briefly:
-The further the FS from VF (thicker shim), you'll make the DOF move nearer
-The closer the FS from VF (thinner shim), you'll make the DOF move further

Therefore,
-Place NO shims, and observe the DOF; it's stupidly obvious with this screen, trust me..
-If it looks like it's behind the central AF point, i.e. the focus confirmation beeps but you see that the DOF is behind, add shim/s. How many exactly, not sure but all i can say is, if it's not too far behind, just add one.
-Rinse and repeat.


PS: Or you can just start off with at least ONE thin shim, and take it from there.

Thank you. I was hoping someone knew exactly how many shims are needed and which ones, but I will give it another go.

The number of shims varies from camera to camera. Since no two are exactly the same.

Just follow this tip of mine and you don't need to guess too much on how many is needed:

-The further the FS from VF (thicker shim), you'll make the DOF move nearer
-The closer the FS from VF (thinner shim), you'll make the DOF move further

Thanks - I haven't given it another go yet. Was at a wedding today and did some manual shooting. I already had the impression that the default screen is good and today's pics showed that I got many good shots using manual focus using 85 and 58mm lenses @ typically f2 but also down to f1.4, in rather dark environments where it was hard to see though the VF.

Now I'm not even sure if I want to change it, tbh.

Zafar, if you have one of those handy rocket blowers, just hold the screen up before installing it and blow the dust/fibers off it. That's what I did while I was installing it. I just held it up to a light source and blew any dust I could see of it (using tweezers of course to hold it and not my hands). I also cut a little piece of paper in a triangle shape and placed it on top of the DSLR mirror so it lessens the risk of getting it dirty or even scratched.

Good luck! It takes a a couple tries to get used to it, but once you do, changing out the screen and adding or removing a shim becomes really quick and easy.

Haven't been too motivated to install the screen till now. Just spent an hour and almost gave up and started to suspect I have a wrong screen when all of the sudden I realized, after googling for instructions, that I had to remove an existing metal shim from the camera... doh!!!

Don't think I haven't missed a better focusing screen than the stock one - I've shot plenty of photos using manual focus and each and every time it felt like I was gambling

Tried some manual focusing before I attempted the install to get a fresh idea of how bad it is. 90+ % out of focus (very low light) using 50mm f2.8 - it's not even one of my 1.4 lenses :P

After the install - tried 4 times. Nailed it 4 times

Don't know if I overlooked something but I had no idea about the existing shim. No wonder I was having such a hard time installing it!

I've manually focused plenty of times but mostly during event and under low light situations and it's therefor been vague how accurate I've been - I've been having a feeling that it been very hard to focus manually (harder than when I used to it it with my K-x and costum focusingscreen). Now that it's warmer, I photograph outside as well and it stands clear the focusing is off. I used the "special" shim, which gave me best accuracy - what could I have had done wrong?

Sounds silly, but are you sure you have not accidentally put the screen in upside down (wrong surface facing the mirror)?

I found the focusingscreen online instructions were easy to confuse because of orientation of the pictures and the natural way to hold the camera when doing the job.

The thought crossed my mind but I also kind of vaguly recall, if it was turned upside down then it was rather clear it wasn't good to focus with.

Been having a lame headache so I didn't bother with the camera too much but I'll have a look shortly, and try reversing the screen.
