Other collecting activities?

Unless it's something seriously obscure, I'd not worry too much about it. Anyway, is it impossible to modify the projector to use some other bulb? Err... I am not tlaking about the horrible point-n-shoot things made in the late 70's/early 80's. I am talking about quality old cameras. Many of them had a good range of shutter speeds, and the shutter will still give repeatable timing (much more important than accurate times for most work) if it's cleaned and lubricated _properly_ (note that flooding a shutter with lubricant will do a lot more harm than good, I am talking about putting 1 drop of watch oil on the arbors of the escapemnet mechanism, and so on). And some older cameras haev pretty decent lenses. Put it this way : I am sure a good 1950's or 1960's camera will give better resolution than a consumer-grade digitial thing! Hmmm.. Most old focal plane shutters will do 1/1000 s. Some will do 1/2000. Leaf shutters are generally limited to 1/500 (and cheaper ones to 1/250 or 1/300), although the Prestor shutter in the Werra does 1/750 (that's one interesting shutter...) But if the only reason you need faster shutter speeds is to be able to use fast film in daylight without stopping the lens down too much (if, indeed it will stop down far enough) then consider using neutral density filters. I am going to have to try this. Yes, and indeed it does hold them base-to-base. I've never seen it, so I can't comment on how well it works (I do have at least 2 Werras...) It shouldn't be that hard to make one. What about the focussing slide be the only person who digs in the junk box at camera shops looking for items to mofify...) I have a book which gives strip-down and repair instructions for it (along with many other Russian cameras), and I've seen _one_ on sale at a rather high price. -tony
