Anyone with excellent eyesight will know if a screen works with
a lens or not. Most don't work

Unfortunately not many people open their eyes when using
cameras and for years we have had a lot of total nonsense
about DOF preview levers etc. and whether cameras should
have them or not.

It's not rocket science... just common sense but it is
beyond most users

Shims are made and supplied by Pentax to adjust screens.

Even if you sort the screen out the focus adjustment on
the lenses is far too coarse. Then there is focus shift
as the lens is stopped down.

A 5x4 is much better having rack and pinion focusing and
usually ground glass and a fresnel.

Here's yet another article on the Canon screens, this time
by a Nikon user:

You need to watch you're metering too. In theory (if not using masks) you should under exposue each shot by a stop for two shots etc, but if there's a significant difference in densities, this doesn't always work.
You then finish up with two shots neither of which have been exposed correctly. Just expose as normal. What happens is that the bright bits of one shot override the dark bits on the other.

We never missed not having shake reduction with film camera SLR's. The K110D didn't have it either and saved a good few grams (75g to be precise) off the weight of the K100D. More than 13% lighter. I wouldn't mind not having it and have always suspected it's more of a marketing gimmick.

Did you mean to post this on the 1st April

Switched over to SKY seems better.... but still Wet!
The big problem with digital is the compression, if they lose
key frames it takes some time to reconstruct the picture

Sorry so it is... I've got a mint MX manual here that I've
never read

You also have to keep hold of the film rewind crank after
tightening it. It also adds one to the counter.

At around the time the MX came out I bought a Minolta Autocord
mainly for double exposures..... you simply pressed a button
and turned the film crank backwards... still got it. It was
a big earner on weddings... mostly the couple in a Champagne
Bottle or wine glass... My drawings of both with a felt tip
are still on the ground glass

I doubt if it's in the manual
The trick is holding down the rewind button and having the
film tight.
