Hello everyone! I tried searching the forum for this problem but can't seem to find a similar question posted previously. I hope you can figure that out.
I have run into a strange problem, namely I am not able to produce prints smaller than 18x18cm (about 7X7").
I use a Kaiser V-System enlarger for formats up to 6X7 and shoot 6X6. The original lens was a 50mm. As it could not cover 6X6, I got a rodagon 105/5,6. Now the problem: the new lens illuminates the whole negative, however I am only able to go down to about 18X18cm print size - the enlarger head won't stretch any further (it's already stretched about 20cm). I would like to make prints on 10X15 paper- can you please advise?
