just returned to film-making after a long time.
I've started running film tests with my Nizo (bought 10 years ago) recently and have reluctantly come to the conclusion that the image may not be sharp. In all other aspects the camera seems to be running smoothly.
a. The lens appears to be OK - glass clear, no dents and the focus ring turns smoothly. What other reasons could there be for a soft image? Cartridge alignment? Are there any checks I can do myself to help analyse the problem?
b Is there anywhere I can get a Nizo serviced in the UK (or anywhere else)?
Thanks for any ideas.
