    I've noticed that my manual focussing is sometimes a little out.

    I'm a glasses wearer and I find that the diopter doesn't adjust enough for me to use the camera without my glasses, but with glasses I can't see the whole view finder as I can't get my eye right upto the camera.

    I've got a Pentax *ist DS. Is it possible to get the view finder adjusted or buy something to rectify the problem?

    I'd heard that manual focus on these camera was difficult. There are other screens available for them, but not a split screen.

    You might be able to buy stronger diopters for the eyecup, but I find these give me a headache.

    You might also find that faster prime lenses will be easier to focus compared to the slower kit lens.

    Surely changing the lens will do no good until I can see the view finder!?!? I run out of adjustment on the diopter before the image in the view finder is sharp!

    I always go the impression that one the strong points of Pentax cameras was their view finders because they use their Penta Prism system!?!?

    A faster lens will give you a brighter image in the viewfinder, and should make it easier to focus.

    Just checked, and it appears that you can't buy the extra diopters for modern DSLR's. sorry - my mistake.

    How about contact lenses?

    I stand corrected. I have to say I thought that split screens would interfere with autofocus. They must have solved this problem.

    I do wear contacts from time to time, but I don't want to have put lenses in every time I use my camera!!

    Going back to the faster lens, I understand your point, but the issue is the fact that sans glasses/contacts I can't focus the viewfinder so I could have the brightest image in the world but it would make no difference as the image in the view finder is out of focus to me!?!?!?
