Hello!
Can you also enlarge 35mm negatives using an Anaret 4.5/80 (on an Opemus 5), or do you need a 50mm lens?
As always, thanks for your advice.

Yes, you can. However, the maximum zoom level is lower.

I usually enlarge my 35mm negatives for smaller formats using an 80mm lens, so that I don’t have to position the enlarger head too low. It also ensures that the negative is correctly projected right up to the edges (after all, a medium-format enlarger has a larger image circle than one for 35mm).

... and the exposure time would also be longer, as the light is still spread across the 6x6 format and only a fraction of it is used (if a condenser is used, the one for 6x6 must of course remain in place). But this only becomes a problem with larger formats or larger quantities, doesn’t it?

No. The exposure time depends on the aperture. The image circle of the lens has nothing to do with it.

You would gain an advantage if you changed the condenser system or the light mixer so that the light from the bulb is concentrated onto the smaller negative.

Uwe, I suppose my answer wasn’t detailed enough. Compared to the ‘proper’ solution – namely a 50mm lens and a suitable condenser (or mixing box) – you do end up with a longer exposure time if you place a 35mm negative in an enlarger set to 6x6. After all, a lot of light is then blocked out by the 35mm mask. I actually do this sometimes too. If I’m mainly using roll films and only a little 35mm, I’m too lazy to switch to 35mm.

One more note for Mario: The 35mm negative in the 6x6 enlarger must be masked properly, so no light must pass past the negative onto the base plate, as this can easily lead to fogging (highlights turning grey). With high negative density, the light coming through the perforation holes is enough to cause this.
