jaapv Posted March 25, 2007 Share #1 Posted March 25, 2007 Advertisement (gone after registration) Contrary to my expectation, it turned out to be quite easy to make macro shots with the M8 and VisoIII .Success rate was about 40%.I tried a whole range of lenses, and the best results were with the 2.8/50 Elmar M and the 135/4.0. All shots are handheld and natural light. The lenses were wearing their IR filters.And I am quite pleased. 135/4.0: 50/2.8: 135/4.0: 50/2.8 Quote Link to post Share on other sites More sharing options...

jaapv Posted March 26, 2007 Author Share #9 Posted March 26, 2007 And the technique is so simple: Mount the Visoflex, slap on the lens of choice, and start shooting. However: a few caveats. Don't use lenses that protrude into the body, like the Summicron 35 asph etc. as they will foul or damage the mirror. Don't collapse lenses, for the same reason. On the M8, don't push the shutter release too fast. The exposure meter will attempt to determine exposure with the mirror down, resulting in complete overexposure. Soft release is less sensitive for this. Don't attempt to focus, move backwards and forwards This is standard macro technique. I use the lenses at about f8 or wider open. These are not macro lenses, so diffraction at smaller apertures is very real. Quote Link to post Share on other sites More sharing options...
lars_bergquist Posted March 26, 2007 Share #10 Posted March 26, 2007 ----- I use the lenses at about f8 or wider open. These are not macro lenses, so diffraction at smaller apertures is very real. Jaap, diffraction is caused by light wavefronts being deflected as they pass close to the edges of the aperture blades. Unless we are dealing with some really outlandish lens designs, the iris diaphragm of, say, a 50 mm lens will be found in more or less the same place and be of the same size (smaller diameter = more light passing close by the rim = more diffraction). Period. The question whether the lens is marked ‘Macro’ or ‘El’ or ‘Use-it-on-everything’ is immaterial. Remember that for instance f:8 means that the diameter of the diaphragm opening is 1/8th of the focal length. The only difference in this respect between different makes or types of same-length lenses is how quickly standard aberrations decrease when you are stopping down, and thus how soon you will observe the effects of increasing diffraction. Very highly corrected lenses go ‘diffraction limited’ sooner than bad ones, which never may do so! The main points of distinction of real macro lenses are the same as for enlarging lenses: a) they are flat-field lenses (no noticeable curvature of field), they exhibit no linear distorsion, and c) they are normally corrected for closer working distances than lenses for general photography, which are usually corrected for infinity. Hence an enlarging lens, e.g. a 90 mm, is very usable for macro if you can live with a fixed reproduction ratio. A screw to bayonet adapter will fit it to the front of the Viso.

jaapv Posted March 26, 2007 Author Share #11 Posted March 26, 2007 I know that, Lars. But these lenses are not properly corrected for such small distances. So it pays not to add to image degradation by coming close to the diffraction aperture which on most Leica lenses in in the order of f 11. On a true macro lens it will be less necessary to be so paranoid about it imo, as these will be producing a higher macro performance in the first place. I tried the 35 summicron asph as well, screwed out to 1m to clear the mirror. Useless for Macro, compared to the two I posted here. Quote Link to post Share on other sites More sharing options...
sharookh Posted March 26, 2007 Share #12 Posted March 26, 2007 Jaap - Do you retract the 50/2.8 into the M8 when stored? Just wanted clarification on this as I have the same lens. New generation - I think. Best Sharookh Quote Link to post Share on other sites More sharing options...

So it pays not to add to image degradation by coming close to the diffraction aperture which on most Leica lenses in in the order of f 11. I thought the "safe" area was between, of course, wide-open, and somewhere around f/5.6 as a general rule. Perhaps I'm wrong. Quote Link to post Share on other sites More sharing options...

New generation - I think. Best Sharookh I collapse it without qualm on the M8. No possibility of a problem. On the Visoflex, however it cannot be collapsed. That would damage the mirror.

Perhaps I'm wrong. 5.6 or 8. In macro, there is not much of a difference. f 8.0 is fine in my experience. Even more critical users might consider 5.6 the limit.

Hans Roggen Posted April 18, 2007 Share #16 Posted April 18, 2007 Got the Viso Jaap! Here's the very first picture. This thing is fun... This was a hard colour to get right. Shot with the 50mm summilux. Thnx, Hans Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

jaapv Posted April 18, 2007 Author Share #18 Posted April 18, 2007 Does a Macro forum exist then? Actually the thread is about the technical aspects of using the Visoflex with macro. Quote Link to post Share on other sites More sharing options...

Shot with the 50mm summilux. Thnx, Hans Very impressive, Hans. It is often maintained that the Summilux is not the best lens close up. But I really love the soft sharpness to oof transition. It suits the subject perfectly. Darn! I knew I should not sell a Visoflex to a pro - it gives me an inferiority complex:rolleyes: Quote Link to post Share on other sites More sharing options...
