Hi all, I've recently purchased a Pentax K1000 and am in need of a little advice. Looking through the viewfinder it looks quite hazy/milky (sorry, not sure of the correct terminology) is this normal? The centre is clear but the surrounding area that is hazy makes it hard to see if I am in focus or not. Could you kind folk advise me on wether this is normal or does it need a good cleaning? Could the old lenses I have for it be the problem? Thank you in advance for any help you can give.
