Scott Root Posted October 21, 2009 Share #1 Posted October 21, 2009 Advertisement (gone after registration) My 50 summilux asph works on my visoflex III, but within a very short range of focus that achieves focus within just a few inches of the subject. Can an extension tube be used to extend the range of focus of this lens on a visoflex III? Link to post Share on other sites More sharing options...
Advertisement Posted October 21, 2009 Posted October 21, 2009 Hi Scott Root, Take a look here extension tube possible with 50 lux asph on visoflex III?. I'm sure you'll find what you were looking for!
carstenw Posted October 21, 2009 Share #2 Posted October 21, 2009 The further you move the lens from the camera, the narrow the depth of field. You need a slimmer Visoflex There are some lenses designed for use with the Visoflex. Try getting an older 135/4 Tele-Elmar with removable optical elements, and get the special focusing adapter for it. Then you can focus from infinity.

wparsonsgisnet Posted October 21, 2009 Share #3 Posted October 21, 2009 I believe that the shortest lens that will focus to infinity on the viso is the 65mm (rather costly). I will look for the lens diagram from the Leica book; it's in another thread. Link to post Share on other sites More sharing options...
carstenw Posted October 21, 2009 Share #4 Posted October 21, 2009 Hmm, my answer was rather incomplete, in hindsight. There are several lenses which can focus to infinity on the Visoflex, the 135/4 is one, and the 65mm, a macro lens, is another. I think there is a 90mm Summicron (not the pre-Asph, even earlier) which can also be used on the same focusing adapter as the 135/4. Link to post Share on other sites More sharing options...
wparsonsgisnet Posted October 21, 2009 Share #5 Posted October 21, 2009 I didn't find the thread with the diagram. I'll get it from my book, tonite, and post the layout. Link to post Share on other sites More sharing options...
michali Posted October 21, 2009 Share #6 Posted October 21, 2009 I've tried to focus my 50mm Summilux with Visoflex III & using the 16469 extension adaptor and it doesn't work in the true sense, you end up barely achieving focus a few millimetres from the subject. It works more like a magnifying glass that's barely focusable. I've also tried it with a bellows attached to the front of the Visoflex, I did this some time ago and if I recall it works but only slightly better. The 65mm Elmar was made for Visoflex so no problems with that, I often use it. Interestingly my 1939 50mm collapsible Elmar works on Visoflex via a Screw to M mount adaptor coupled to the the 16469 adaptor then mounted onto the front of the Visoflex. By extending or collapsing the lens one is able to achieve focus. Link to post Share on other sites More sharing options...
michali Posted October 21, 2009 Share #7 Posted October 21, 2009 Advertisement (gone after registration) I believe that the shortest lens that will focus to infinity on the viso is the 65mm (rather costly). I will look for the lens diagram from the Leica book; it's in another thread. Bill is this the diagram you're referring to? Trying to read this chart is like learning trigonometry all over again... If you look on the left side of the chart at the bottom you will see that you can't focus to infinity on either the 35mm or 50mm, even with the 16469 adaptor. Bill & Carsten are right, moving along the bottom of the chart you will see that the 65mm is the shortest focal length that will focus to infinity via the 16464 extension adaptor.

Scott Root Posted October 22, 2009 Author Share #8 Posted October 22, 2009 Thank you all for this information. What lens on the chart would you consider the sharpest? Link to post Share on other sites More sharing options...
michali Posted October 22, 2009 Share #9 Posted October 22, 2009 Thank you all for this information. What lens on the chart would you consider the sharpest? Scott- IMO and experience the 65mm Elmar is by far the sharpest, others may have found differently. I have a black 1962 in mint condition, it's a beautiful lens. There are several versions of the 65mm Elmar, Black- made in Germany & Chrome- made in Canada. The original early 1960's model needed the 16464 (OTRPO) focusing & extension adaptor. The lens screws into this is adaptor which has an M bayonet at the back which fits onto the front of your Visoflex M. The later (after mid-1960's) 65mm lenses came in an M mount. They're not difficult to find, prices range from EURO450.00 up to EURO1, 000.00 Have a look at these 2 links to see what I'm talking about: https://www.leicashop.com/vintage/leica-visoflex-lenses-elmar-3565-black-c-1000_1005_100502.html https://www.leicashop.com/vintage/leica-visoflex-lenses-elmar-3565-chrome-c-1000_1005_100501.html Link to post Share on other sites More sharing options...
michali Posted October 22, 2009 Share #10 Posted October 22, 2009 The later (after mid-1960's) 65mm lenses came in an M mount. Let me correct myself to avoid confusion, they all need the 16464 adaptor it's just that the later models came with a matching black adaptor. Link to post Share on other sites More sharing options...
carstenw Posted October 22, 2009 Share #11 Posted October 22, 2009 The 135 Tele-Elmar is apparently also sharp, but not as sharp as the 65mm. The 65mm lens is one of the most expensive non-current (non-collector) Leica lenses, and although it is good, there has been some discussing whether it is in proportion to the price. Still, if you need one, you need one. Link to post Share on other sites More sharing options...

Scott Root Posted October 23, 2009 Author Share #13 Posted October 23, 2009 Thanks for this information, but the 65 elmar is rather expensive and perhaps it would be better to double that investment and get a used 90 macro elmar with goggles.

wparsonsgisnet Posted October 23, 2009 Share #14 Posted October 23, 2009 Scott, Look for the lenses shown along the bottom of the chart. You ought to be able to find a 90 'cron or 135/2.8 in the $500 range. I have the 90 and had the 135 and both are good lenses. In the case of both of these lenses, the front element, the part with the glass in it, unscrews and fits into a tube specified in the chart. I have acquired tubes in the past in the $150-200 range. I suggest you do a search on the Forum for visoflex. There are several threads discussing various lenses. Link to post Share on other sites More sharing options...
UliWer Posted October 23, 2009 Share #15 Posted October 23, 2009 Thank you all for this information. What lens on the chart would you consider the sharpest? The lens head of the 2.8/90 Elmar together with the 16464-Adapter gives very good results. By the way, I just tried a very odd combination with the 4/200-Telyt on the Visoflex. The photos are not meant for serious, but if you focus correctly you get astonishing results from a distance of about 1.50 meters: http://www.l-camera-forum.com/leica-forum/leica-sammler-historica/103293-warum-hat-oufro-nicht-9-mm-2.html#post1090702 If you really want to use the 50luxasph on Visoflex, you might try it on the bellows II. It is in no way practical, but just to find out that this excellent lens gives the worst results on close distances, any old 50 Elmar is much, much better (it is really good!). The modern 50lux was never made for such purposes. The simpler constructions from old age could cope with extreme situations. Link to post Share on other sites More sharing options...
thirdwheel Posted October 25, 2009 Share #16 Posted October 25, 2009 Thanks for this information, but the 65 elmar is rather expensive and perhaps it would be better to double that investment and get a used 90 macro elmar with goggles. They are quite different I think, because the 90mm Elmar cannot focus as close as the 65mm with the 16464 adaptor and the Viso. Nevertheless I have the 90mm Elmar, and can say that it is a very good lens. See these pictures taken with it on an MP, no photoshop. The only issue is that there is a limit on how close you can go.... Welcome, dear visitor!

thirdwheel Posted October 25, 2009 Share #17 Posted October 25, 2009 Again this was not Photoshopped in any way. It's close enough if you have a big enough subject, but capturing small flowers in macro perspective for example may be difficult.... Welcome, dear visitor!

michali Posted October 25, 2009 Share #19 Posted October 25, 2009 Nice watch. Thanks for sharing your excellent photographs.
