Focusing with a Durst M605 color enlarger

greenspun.com : LUSENET : B&W Photo - Printing & Finishing : One Thread

I recently started printing my own photographs. I own a Durst color enlarger (M605) that I am using to print black and white photographs. Everything, so far, seems to be working OK. However, there is one dilema I can't figure out: the optimum focus for any size print I make is with the focusing bellows compressed almost completely. It doesn't matter what size print, or how far up and down I move the head on the rail, the compressed bellows gives the clearest focus.

Why is this? I can't figure out why they have a bellows that will extend 8-10" if you never have an application to use this. There aren't a lot of switches, levers, and knobs on the enlarger; it is pretty basic. And everything I have tried, with my limited knowledge, has not effect. If anyone has any ideas, please advise.

The last year I have used the photo-clubs M605 so I'm pretty sure what causes your problem. Let me guess: you are using a 50 mm lens but with a lens board for the M305? Or, you are using the M605's flat lens board with a 50 mm lens? If any of those are what you do, than you will have trouble to get any focus at all, because the distance from the negative carrier to the lens will be too long. You need a recessed lens board. Right or wrong?

Good luck.

I am new to the list, and I see your query goes back to Feb'99. Just in case you have not solved the problem yet, here goes. Your M605 should have been supplied with two lens panels. The one that you are using, intended for 75mm focal length lenses and longer, Code SIRIOPLA, And a recessed one Code SIRIOTUB for 50mm lenses. Both have M39x26 TPI screw threads. You should be able to get a SIRIOTUB panel from your Durst dealer. The M605 is a good enlarger. Good printing
