Hi,
I am working on a Holga 120 Pan conversion to accept a "real lens"...
Looking at various 90mm F6.8 Angulon lenses with a Compur shutter I might want to have the shutter checked out. To make sure the shutter speeds are correct (as a antique lens can be...).
Any idea if this is something I can do myself or know where to have this done at what cost?
BTW if you happen to have a lens available I am happy to hear from you
This is the inspiration for my project:

Looks like a fun project. The Angulon 90/6.8 is a good candidate. I use one on 4x5. Compared to a Super Angulon, it does go soft in the corners, but the 6x12 format should deal with the worst of that. It has good sharpness and contrast, and is super compact.
Most good camera repair people can give a leaf shutter a CLA. I would not do that myself, although some on the forum do. The cost varies, but could be as much as the lens. The Angulon is one of the best bargains out there. I got mine thrown in with an accessory I was buying. The controls on it are kind of stiff, but other than that everything is as good as it could be.

Thanks, I just checked the Super Agulon. Don't think that one will fit my FrankenHolga ;-)

As suggested above, I use one of these as my wide(ish) lens on a 4x5:

I paid very little as the elements are starting to seperate at the back, but image quality is still very good. its pretty damn compact too, ideal I'd say.
if you have a PC and soundcard you can quite easily rig up a small circuit with a battery and photodiode to measure shutter speed.

You are right that the Super Angulon own't fit, the rear element is too big to go inside the Holga body. But the 90mm Angulon is a superb lens, covers the area without breaking into a sweat, and it is very sharp. Terrific results can be got from this conversion, but it is well worth taking the whole camera apart and starting from scratch, making sure it is light tight and constructed just a bit better than the original donor body. It is also supremely light when finished, making the slog to the top of a hill bareable, unlike some larger format cameras.

Making progress.
The hardest part was to make a 32.5mm hole in a M42 lens cap. This week I hope to calibrate the helicoid. Not sure about measuring the distance. Either a rangefinder mounted on the hotshoe or a hand held laser range finder..
