I would be interested to know what is the mimimum print size you are able to make when printing 5x4. Here is my problem - I use a Durst Laborator 1200 fitted with a 135mm EL Nikkor enlarging lens. I want to make some 11 x 8 prints for scanning but can't get the enlarger to focus at that magnification. I have to go up to about 13x10 before I can achieve correct focus an even then the enlarger bellows near maximum extension. Unusually I can manage if I fit my 80mm lens but this cant be right surely. When I make 14x11s I have no problems but the bellows are still fairly extended. When I use this enlarger for 6x6 with the 80mm lens fitted everything is fine. I would be grateful for any advice the readership has to offer. Thank you.
