Durst M601 problem
I have just bought a Durst M601 enlarger. Mounted it and started playing with it.
It came with two lenses: 50mm and 105mm.
With 35mm I have no problems, image looks ok but the problem is when I try it for 6x6 negatives.
I think the condenser light is not covering fully 6x6, I have mounted it as the manual says (curved face to curved face). This is how it looks without lens:
And how the enlargement looks (with the 105) I've tried minimum and maxim size, still the same:
Some info on photo.net here:
Just to clarify, the 'square' condensor is called a "Sivocon 80" (it's written on the side). The 'round' one is a "Sivocon 50" and has the same square frame as the 80.
For 6x6 you use two 80's, with the curved surfaces facing each other. For 35 mm you use one 80 and one 50, again with the curved surfaces facing each other. I actually put the 50 on the bottom, not the top, which gives you a little bit more light, but the illumination is even whichever way up you have them.
You can use the 6x6 setup for 35 mm, but the light level will be lower and you'll have longer printing times. The 35 mm setup leaves the corners of a 6x6 frame very dark.
So you are missing one of the two Sivocon-80's needed?
There's two on German ebay right now, shipping ww.
Thank you, exactly that's my problem. Unfortunately the manual misses this information. Probably the person before used it only for 35mm, the seller on eBay missed this information, somebody will get a bad review .
Oh, there is another set here, in Belgium. Cheaper than the one on ebay. You can always ask the guy if he wants to ship to Cyprus.
I had an M-601 years ago, left the condensers in the 6x6 position all the time. I shot more 6x6 than 35mm and did not find the extra printing time inconvenient.
What is a master but a master student? And if that's true, then there's a responsibility on you to keep getting better and to explore avenues of your profession.

I have a 601, and I also only have the 6x6 condensers. I've thought a few times about getting a 50, but haven't found one at a reasonable price...
I bought my 601 new in 1975 or 76. It's a good enlarger. I usually use the color head for multigrade printing. The color head has different mixing boxes for 35mm and 6x6. That's another option, if you can't find the condensers. It will also give you more diffuse light.
Problem is that I have the color head but it's not working. I don't know if it is the transformer of the bulb, I will need to check but I don't have the necessary tools for now.
I have another question, if I'm still here. In the filter drawer, I can put any type of color filters I want, or I need something heat resistant ? I found something no-name (but on a well known film store), I'm on a budget now as my darkroom expenses lately were huge
Thank you all, very much!!!
The filter drawer is sufficiently far from the light source never to get hot, only just a bit warm (in the sense of making your negatives 'pop', not melt). Your filters should be at least as tough as your negatives, think of it that way.

I haven't used mine for a while, but if I remember correctly, the thin (film) filters can sometimes bow upwards from the heat of the bulb if you use a high wattage. Usually, a tiny filter frame was enough to keep it from doing this. Just check it after a few minutes with the bulb on. If it bows, you could either try a thin frame or even a same-size piece of thin glass would work, though you'll have to remember not to yank open the drawer and accidentally flipping it out of there.
