kenghor Posted January 4, 2004 Share Posted January 4, 2004 To ease and speed things up, save on the gaffers' tape. Set camera to AV mode. Press the lens lightly against the lens mount of the body. Shift yourself to attain focus. Just trigger off! Link to comment Share on other sites More sharing options...
pete1 Posted January 4, 2004 Share Posted January 4, 2004 Where did you get that nobby focussing attachment for the noctilux and are they available for other lenses such as the 75 lux and 90 cron? Link to comment Share on other sites More sharing options...
fotografz Posted January 4, 2004 Author Share Posted January 4, 2004 Here's a crop of my Nocti image. Usually when going up this far some color fringing starts showing up. These M lenses are really highly corrected if this is any indication.<div></div> Link to comment Share on other sites More sharing options...
mark_rutledge Posted January 4, 2004 Share Posted January 4, 2004 Picked up a homeade rig off EBAY for $10.00. It's an M-mount part(#16469, not knowledgeable enough about Leica gizmo's to know what it's from) epoxied to Canon EOS T-mount adapter. It leaves the lens pretty far from the film plane so I was thinking of mating it to a M42-EOS adapter. It would still be macro but perhaps give a little more minimum focus. I contacted S.K. Grimes about an adapter and they said they had and can make a custom job. I had heard from a photographer friend in town that he knew of a guy that had Grimes make an adapter and used it shooting some annual reports.

fotografz Posted January 4, 2004 Author Share Posted January 4, 2004 Pete, it's called a "Steer" and is an item from Lutz (a forum member here). I have one on my Nocti, 75 Lux and 90AA. Another shot with the "Gaffer Tape" adapter...<div></div> Link to comment Share on other sites More sharing options...
fotografz Posted January 4, 2004 Author Share Posted January 4, 2004 Can you believe it? I have a Mac 23" cinema display and can fill the screen with these images without loss of quality !! It looks like Medium Format stuff. And this was just the 10D. What the hell will it look like using the 1Ds I wonder? I need this to shoot jewelry assignments. Diamonds cause all kinds of problems when shooting digital that these lenses may help solve for me. Leica, wake up for God's sake. Link to comment Share on other sites More sharing options...
dan flanders Posted January 4, 2004 Share Posted January 4, 2004 Could the Fresnel principle be employed to make a screen that would straighten out the rays from the shorter lenses so that they reach the focal plane in parallel rays? Link to comment Share on other sites More sharing options...
jay_. Posted January 4, 2004 Share Posted January 4, 2004 14167 M (Viso) to R adaptor, plus Novoflex R-EOS adaptor. I used my 400/6.8 Telyt-V on my D30 all the time. Any of the removable-head M lenses with the appropriate short-mounts would work on that combo also. Stephen Gandy www.cameraquest.com has Japanese-made versions of the above adaptors as well.

EricM Posted January 4, 2004 Share Posted January 4, 2004 Marc, I can see it now! Your clients will arrive with secure case's and ultra expensive product, and you'll whip out a camera with duct tape holding the lens on... Good work man, if it wasn't for people like you, we'd still be on a horse and carriage! Link to comment Share on other sites More sharing options...
b_n_f Posted January 4, 2004 Share Posted January 4, 2004 Spectacular images, Marc. Can you produce the same shots with another manufacturers' lenses so that we can compare, even just a little bit? Then again, with your skills, the equipment doesn't seem to be the biggest variable in the shots. The composition, lighting, framing....all make the shots work.

gary_ferguson1 Posted January 4, 2004 Share Posted January 4, 2004 Wouldn't you get even better results by reversing the lens, so that its front element was closest to the Canon body? Link to comment Share on other sites More sharing options...
fotografz Posted January 4, 2004 Author Share Posted January 4, 2004 Tried your suggestion Gary. Doesn't work. Zero focus even moving in as close as possible. The lens is to far away from the sensor. Link to comment Share on other sites More sharing options...
lutz Posted January 4, 2004 Share Posted January 4, 2004 Hi Marc, thanks for your confidence in my craftsmanship, but in this case I would have suggested what Jay says. Nice light, as always. Next time I need product shots I'll send you my prototypes... ;o) Link to comment Share on other sites More sharing options...

andy_piper2 Posted January 4, 2004 Share Posted January 4, 2004 Ingenious, Marc! Like Jay said - there is an adapter path already in existence. The M-to-R adapter adds a bit of depth, so your results would be "more" macro than just using the gaffer's tape. Except, of course, with the short-head lenses. I did a similar trick hand-holding a 90-M against the front of my Leicaflex SL at a time when I had no macro lens for the SL - same scale, different capture material. Does the 10D have mirror-lockup? It might be interesting/fun to (carefully!) try the Leicaflex-mount version of the old 21 Super-Angulon f/3.4 (same optics as the M-mount version, different mount/barrel). It would give a good idea of just how much corner fall-off and other artifacts really would result from using a short-focus "true" wide-angle on an imaging chip. The apparent focal length on a 1.6x-mag-factor chip would be 34mm or so. Should allow infinity (scale) focusing. Also - Cosina now makes SLR mirror-up versions of the 15mm lens (and I think even the 12mm), at least in Nikon F mount. I think cameraquest has Nikon F-to-EOS adapters. They would equal 24 and 19mm fields of view on a 1.6x chip. Seems like you could cobble together a pretty decent 'proof-of-concept' rig that covers all the "M" focal lengths out to infinity. If we could demonstrate that lenses with really short backfocuses can, in fact, be used with current image sensors and produce acceptable images, we might be able to get some manufacturer to move off the dime and make a body to use them.

billsr Posted January 4, 2004 Share Posted January 4, 2004 Long before digital came along, in 1960 or so, my friend used to photgraph his stamp collection by hand holding a reversed lens against his camera to make very good macro shots. Best regards, Bill Link to comment Share on other sites More sharing options...
jack_lo_..._t_o Posted January 4, 2004 Share Posted January 4, 2004 A company in Japan makes OM lens adapters for EOS cameras. It's on a thread by Neil D. in the Olympus Forum on Sept 05, 2003. Just look up the archives of the Olympus forum. The address of the company is even mentioned. Good to see you so excited, Marc. Still, it gives me a "Handwriting is on the Wall" feeling. Needed therapy, so I went out and took about 50 shots of my favourite bridge... Link to comment Share on other sites More sharing options...
jake_tauber Posted January 4, 2004 Share Posted January 4, 2004 Call the Smithsonian!! Very cool. Now, isn't there an electronics guy on the forum who can glue a CMOS sensor to the pressure plate inside an M body? Link to comment Share on other sites More sharing options...
john_morris4 Posted January 4, 2004 Share Posted January 4, 2004 Cool. I could probably put a 10D or 1DS sensor in the back of an M, if I thought it were worth the trouble (and if I could afford one). Mark, the test I would really like to see -- and you're just the guy to do it -- is to lock the mirror up on a 1DS, put a shorter Leica lens in there (like a 24, 28, or 35), focus at normal distances (by trial and error, I suppose), and see how bad the performance at the edges REALLY is. Leica (and others) keep saying that we'll never see a full frame M because current sensors won't work with the sensor so close to the lens. But I'd like to see what really happens. Are there color problems? Is the main problem just light falloff (which could be largely corrected electronically)? Does the antialiasing filter in front of the sensor make the sensor more tolerant of non-perpendicular rays? If a 1DS sensor makes good images with a Leica lens, then someone could certainly put that sensor (and electronics) in a Leica body. Link to comment Share on other sites More sharing options...
rico_tudor Posted January 4, 2004 Share Posted January 4, 2004 Sorry, John, but EOS lacks MLU capability, only mirror pre-fire. Unless Marc <i>tapes</i> the mirror up (and that sounds dicey), symmetric WA's are out. I've played the "hand-held" adapter game with Contax SLR lenses in front of a D30 - fun stuff! For Leica and CV M lenses, you need the real-deal MLU from the RTS III, Nikon F, K1000, etc. Link to comment Share on other sites More sharing options...
mark_bohrer1 Posted January 5, 2004 Share Posted January 5, 2004 Steve Gandy/www.cameraquest.com sells M or R to EOS EF adaptors. Visoflex lenses used with them focus to infinity.

kenghor Posted January 7, 2004 Share Posted January 7, 2004 Checked with Stephen Gandy. He has no adapters for M on EOS, but may have such an adapter for closeups later this year. Link to comment Share on other sites More sharing options...
