It's true that the Novar is not the best lens ever made (and not the best triplet design - to me, the best of these is the Meyer Trioplan) but it...
Many years ago I was looking for a 28mm lens for my Leica/Canon7 bodies but did not want to spend $$$$- So I bought a M42 28mm f/2.8 as cheap as...
First thing to check are the contacts of the battery tray. Contacts and wires which are close to (former) mercury cells are prone to corrosion....
The shutter seems to be a clone of a german Prontor shutter. Anyhow, if you are new to camera repair, you should not try yourself. Usually these...
My experience with the Moskvas is that it mostly depends on the general shape of the camera. Obviously there are many worn out samples around,...
Actually I never stumbled across the unit designator "cmp" although I was raised in a metric country where pond was used as a physical unit. But I...
It will not be possible to solve this problem without disassembling the focus mount. To get it loose again, you should warm up the lens mount...
Hello, sorry this was years ago, I don't know where I got the CdS resistor from. I faintly remember that it was a standard item from an electronic...
Over the years I had had many cameras in my hands and fixed quite a few of them. Also, I have a degree in precision engineering. And all this...
As far as I know there were just a few zoom lenses available from VEB Pentacon in M42 and/or Praktica B mount towards the end of production of the...
<p>Just a warning: Sometimes even the normal shutter mechanism (or blades) are stuck and the shutter does not fire at all. Some people think that...
<p>A "press focus lever" makes sense only on cameras where you control the focus on a ground glass. Like some others, I rather think this is the...
<p>All the leaf shutters I had in my hands (and there were quite a few) did not have any kind of interlock for keeping them open. The blades are...
<p>I do not know whether I ever looked through the shutter when firing without battery but you find pretty often the information that the shutter...
<p>The "power" of a lens (or luminosity) is NOT affected by crop factor/frame size etc. A lens with a max. aperture of f/1.8 has the same light...
<p>I have done a few weird things with cameras but never managed to damage the advance gears. In most cases, if you hear strange sounds when...
<p>I think so too. The galvanometers in cameras usually use a quite simple toe bearing system. In some cases you might be able to push back the...
<p>As (probably not only) German mechanics say, "a little oil can do wonders". You may try to apply VERY LITTLE of gun oil with the tip of a...
<p>Probably not... 110lpm would be a very excellent value, and also it does not make sense to give one value only since lens resolution is not the...
<p>Concerning soviet lenses, they probably often suffer from inadequate repair attempts. The Jupiter f/2 85mm lens, for example, has three...
