I have got quiet a few of the Pentax Manual A lens and as my eye
sight gets worse with age I find it more difficult to focus the
manual lens on the ist D. I have read about interchangeable focus
screens being available.
Was wondering
1. Which interchangeable focus screen would be best.
2. Where would I purchase one from
3. Could I change it myself, if so any one know where I would get
instructions to do this. Or is it a professional job.
The screens available from Pentax are essentially the same as the
stock screen with some additional scribed lines as compositional
aids. Yes, they are user-serviceable and come with instructions. In
the US, I ordered the LL60 "Divided Matte" screen direct from Pentax
USA. This is a screen with scribed reference lines, H&V, useful for
aligning horizons and vertical elements.
Tekade.de produced a short run of screens with split-image
rangefinder focusing aids, but I don't think they're making them any
more. They have some problems with spot metering accuracy.
A useful accessory to aid focusing, particularly when working on a
tripod, is a Pentax Magnifier FB. It gives you a 2x enlargement of
the central portion of the viewfinder and then flips out of the way
for framing purposes. I find it useful occasionally when using a 14mm
to 24mm lens even when shooting hand held.
