K10D + LL-60 Focusing Screen + K/M lenses

It Works !!!

Just got my new LL-60 Focusing screen, and installed it into my K10D eager to test that green button magic.

IT WORKS !!!

Tested on
Pentax SMC A 50 1:1.4
Tokina AT-X 80-400 1:4.5-5.6
Vivitar 2X Macro Tele Converter + the SMC 50.

Each lens tested both with Av mode and then M mode + green button at 3 apertures - opened, closed, in between (of course the TC + 50 was only tested manually as the TC has no contacts). The Tokina was tested at 80/200/400. The TC was also tested in 1:1 macro mode.

Conclusions - It works.

Now, if you can answer my 2 questions :

1. Why doesn't Pentax equip the K10D with the *ist screens ?
2. Any recommendations for a good K/M lens to look for ?

Hope this will help some of you

Another thread on the subject raised the issue of the (in)accuracy of manual focusing with this focusing screen.
As I didn't pay to much attention to this in my original testing, I tested the (manual) focusing accuracy today. Testing was done with 2 lenses at several focal lengths again a focusing chart and in real-life situations.

NO PROBLEMS WITH THE FOCUSING WERE FOUND.

(I did find that my SMC A 50 mm 1:1.4 suffers from CA - never noticed it before .... it's a lesson for me - don't test !)

Are you saying it fixes the M/K metering problem? What sort of screen is the LL-60?

That's exactly what I'm saying.

The screen itself is designed for the *ist line of cameras but fits perfectly in the K10D (seems exact same size). There are 3 different screens for the *ist's and the only difference between them is the lines etched on them - so any will do the trick. They are easily bought new (mine is from B&H)

I didn't realize there was a focusing issue with the K10! Could someone explain what problems they've been seeing?

It's not a focusing issue - it's a metering issue with K/M lenses. The K10D does not properly meter by using the green button with non-A lenses.

Apparently, using a focusing screen from the *ist series corrects this.

I think I'm going to pull the screen out of my D and give this a try before ordering one.

I'd appreciate it. Another data point would be nice. Sounds like this might be an easy way around this issue.

Thanks to the OP, as well.
