  1. <p>Yes and no: there is no mirror shake. But the m4/3 cameras aren't rangefinders. The viewfinder helps in low light because the image is corrected for exposure. It becomes as light or dark as the actual exposure. So you can see the depth of focus without the image becoming darker like on a SLR.<br>

    The GF1 focusses faster because of the high frame rate, the Olympus cameras have IS.</p>

  2. <p>If you count the threads in the shutter cloth, you will see it matches the dark bands in the photo. It is about 50 pairs. This cloth is lead around a metal strip to create the shutter slit.<br>

    Like stated earlier, a little dirt on the edges of the shutter cloth can cause the dark bands. This may be a little residue from lubrication.</p>

  3. <p>Maybe the flange distance is a little bit off. That could mess up things. The lens itself is pretty straightforward. As long as you don't guess 2m to be 0,3m, you should be fine.<br>

    Is it focus-unsharp or motion blur? That can happen at 1/30 or 1/15. Did you check with shorter shutter times to rule that out or can you see it is focus unsharpness?<br>

    If it is focus unsharpness, take the new camera back.</p>

     

  4. <p>I sold the 40 Rokkor pretty quickly after getting my CLE. Maybe I shouldn't have, but I like my 50 Quinon Sonnar a lot. Especially at longer distances I found out the frames match very well. Just imaging the frame a little tighter.<br>

    I don't have a 28mm lens either... 25mm works miracles at the full frame. And the old Canon is a wonderful small package.</p>

  5. back door...back door.

    Did you notice the different colour of your light streak? That is because the light coming from the back creates a different colour on film than light coming from the front.

    Light coming from the front can't cause the streak starting a few mm into the frame. Back door leak will do this.

    Been there, cured that.

  6. Have a look at the back door. Top of the image means bottom in the camera. The streak starts at some point in the frame, this means back door. You may have had the camera in more light than with the other shots, explaining why only this shot.

    This is not a shutter hole.

    You can add some felt-like light trapping material between body shell and back door. Not too much ofcourse.

     

    good luck!

  7. No.

     

    It is all about film to flange distance. Have a look at:

    http://www.markerink.org/WJM/HTML/mounts.htm

    for more info on lens registration.

    Adapters - without glass elements - are only possible to adapt lenses for larger registration distance systems to cameras with smaller registration.

    Such an adapter simply fills the gap. That is the case with screw-to-MD or -Maxxum adapters. The other way around would require image-degrading optics or it would restrict you to macro, or loss of infinity focus.

     

    cheers, Rob.

  8. Fitting the winder takes some fiddling. It is almost like a normal baseplate, but not quite.

     

    When I got my M4-2 motor it was banging very loud. You could feel it banging against the plastic housing.

    The cure for a loud winder (as most without maintanance are) is very simple. Somewhere on this site (I think) is a thread with detailed photos of howtodo. But it's pretty straightforward.

    Originally there is some buffering material that was gone in my motor. Instead I put a little piece of glazing rubber (about 3mm thick) and glued it in its place. Then the movement of the rotor has to be limited so it can just make the rotation and stop the current. Then the winder will be as whisperquiet as it can be.

    I tried the winder without film, the shutter is still in order. YMMV I guess. Not making a habit of shooting blanks though.
