stickan1 Posted January 31, 2012 Share #1 Â Posted January 31, 2012 Advertisement (gone after registration) I just bought a Ricoh GXR with the M-adapter as I sold all my DSLR stuff. But I would like to be able to do some macro work (not 1:1 perhaps, but shorter distances than 0,7 meters). I have tried to find an extension tube and there seems to be old ones as part of the Visoflex system (Leica OUFRO/16469). But they are difficult to find and collectors items. I am not a collector and can buy third party products. Â Have anyone spotted alternatives? There shold be a market coming up now with EVILs and Leica M adapters.

duckrider Posted January 31, 2012 Share #2  Posted January 31, 2012 How will You get into correct focus? M9 does not have preview.

Erik Gunst Lund Posted January 31, 2012 Share #3 Â Posted January 31, 2012 OUFRO MACRO LEICA EXTENSION TUBE ADAPTER 16469Y Or 'Macro tube adapter' should give you some hits on the bay Link to post Share on other sites More sharing options...
stickan1 Posted January 31, 2012 Author Share #4 Â Posted January 31, 2012 Thanks for your answers Thomas, The idea is to use an EVIL body and Leica and Zeiss Glass. Then you focus with live view. Erik, I have searched and found a couple of the old ones, but my question was if there is anyone who has started to produce new ones? Link to post Share on other sites More sharing options...

bill Posted February 1, 2012 Share #8 Â Posted February 1, 2012 So, just as an alternative, I use a GXR with M Mount and a 60mm Elmarit-R with a Leitax mount. The two are joined by a Novoflex Nikon F to Leica M adaptor which I bought from SRB Griturn. Â This is the sort of result I am getting, handheld, wide open.

rickp13 Posted February 1, 2012 Share #9  Posted February 1, 2012 my 'inexpensive' solution on a panasonic G1 with M adapter was to use any combination of the three inexpensive LTM tubes (euro 10+) shown below with LTM/M adapter and whichever ltm lens was available (90 elmar, 135 hektor etc). the results were acceptable for my purpose.  good luck  rick Welcome, dear visitor!

christer Posted February 3, 2012 Share #11  Posted February 3, 2012 Here are two shots I just made with the 90mm f/2.8 Elmarit-M mounted on a NEX5n (eeeasy to focus) with a Novoflex adapter. Both shots were made at approximately minimum focusing distance. One of the shots was made using the OUFRU (see above with link to eBay) and the other one using just the lens.  With the OUFRU the smallest object field is just under 10 cm wide compared to 22 cm without.

christer Posted February 4, 2012 Share #12 Â Posted February 4, 2012 I should have said that the net thickness of the ring is 10 mm. Â With Rick`s rings totaling over 100 mm you should be able to get real close.... Link to post Share on other sites More sharing options...
SJP Posted February 4, 2012 Share #13 Â Posted February 4, 2012 For the DIY - Heath Robinson types (a few members come to mind) I guess it would be possible to make an extension tube from a body and lens (M-bayonet) cap. Glue together and then cut out a circular opening with a hot wire/soldering iron. With some machining skills even a threaded version would be possible I guess, using nylon, PVC tubes as variable length element. Â This is where live view would be useful, OTOH you could make a focusing aid "ruler" for a specific geometry of the extension tube & lens (e.g. string & bead). This would require a single calibration shot to determine the focus (set lens at infinite, or closest focus & keep that as the default macro setting). Â I smell a project Link to post Share on other sites More sharing options...
christer Posted February 4, 2012 Share #14  Posted February 4, 2012 Yes, that project would be the logical next step from the pin hole contraption.  (Picture made with 50mm Cron and OUFRU on a NEX 5n.)

Focusing is easy enough I guess;)  I have no scans, just this snapshot.  The picture itself, as well as several others, all pin hole photos, was sold at my 2010 exhibition.  Yes focusing is easy. Holding the camera steady during exposure is quite difficult. Welcome, dear visitor!

stickan1 Posted February 16, 2012 Author Share #17  Posted February 16, 2012 I bought an OUFRO and it came today. I works fine. I tested with a couple of lenses and the shorter the lens the greater the effect as expected. With a Biogon 21mm the min distance was very short but so was the maximum distance, measured from the film plane it was from 12 cm to 13 cm. But with a 90 mm lens you have a working distance between 40 cm and 80 cm. Here is a test shot with a 90 mm lens, it is a focus stack of 4 images, the DOF gets extremely short. The camera body was a Ricoh GXR with M-adapter. I think that this rig will work for me. This image was taken with a 90 mm Konica Hexanon lens, no cropping.  Welcome, dear visitor!

christer Posted February 16, 2012 Share #18 Â Posted February 16, 2012 A rather large box it was, wasn't it? Â With regard to shallow depth of field, the type of set-up you used allows easy testing of how different apertures afffect the depth of field with the results being available more or less instantantly. When I tested with the OUFRU I was pleasantly surprised to see how little diffraction there was when I used small apertures. Â BTW, with "small aperture" I mean f/11 or f/16 and not f/4 - but I have noted that some "digital experts" now call f/4 a small aperture because 4 is smaller than 11 or 16. I wonder if they use the same logic for describing sensor sizes. Link to post Share on other sites More sharing options...
