  1. Re: Linhof Technika 4x5 parts... Need 2 screws... Hard to get!

    Shouldn't be hard to make. But need more dimensions to make a replacement. Things like diameters, thread type, length of the threaded part, place and diameter of the cross hole and type and size of...

    Re: identifying an Omega enlarger

    Thanks for that one. I had found a D2 manual, but this one is better legible and corresponds better to the enlarger I have. So it is now clear to me that this is a D5 with optional turret but without...

    Re: identifying an Omega enlarger

    If you mean the large knob, yes, that is present (other side of the one I took a photo of). It was stuck because the grease had hardened. Bit of cleaning with some petrol loosened that up nicely.

    Re: Preferred Format, and why?

    I really like the 2x3 ratio. At least it has an obvious direction, something I miss in 6x6 or 6x7. So for me it would be 6x9 as preferred format but sadly I haven't found any camera to my liking in...

    Have been looking there, most of what I wrote is from what I found there. Looks mostly like a D5 with the covered rails but with a tree-lens turret.

    identifying an Omega enlarger

    I got hold of an Omega enlarger. It was advertised as a "D2 with color head". As Omega isn't that much around here I took it for granted that is what is was.

    Now I looked a bit on the net and...

  12. Re: "The big two" - Please tell me about your japanese lenses!

    I like it a lot. I made a fix focus one with the same lens as you did, but a rangefinder is better. Can you really use it handheld without being forced to use high iso film?

    mA rating has nothing to do with this so it should be safe. What can be a problem is that the voltage over time is different. Mercury cells have a very flat discharge curve, their tension varies...
