dkCambridgeshire Posted February 4, 2009 Share #1 Posted February 4, 2009 Advertisement (gone after registration) Anyone have any thoughts on possibility or feasibility of a SHIFT adaptor for the MFT format? As FD and M lenses cover twice the image circle there seems to be scope for a shift adaptor. I bought a G1 today and now need an M adaptor so will be investigating same and checking the threads here.

andit Posted February 5, 2009 Share #2 Posted February 5, 2009 Hi Dunk, There was a long discussion and links for these adaptors in this thread http://www.l-camera-forum.com/leica-forum/digital-forum/76701-m-lens-adapter-g1.html Good luck, and post some images. PS: I see that there are FD adaptors for the G1 as well. Those tilt and shift lenses should do a stunning job on the G1. Andreas Link to post Share on other sites More sharing options...
sean_reid Posted February 5, 2009 Share #3 Posted February 5, 2009 It is an excellent idea and something John Millich might want to consider. He and I once talked about making a shift adapter for the 20 Flektogon (on EOS) and I know the basic concept intrigues him. Cheers, Sean Link to post Share on other sites More sharing options...
marknorton Posted February 5, 2009 Share #4 Posted February 5, 2009 In theory, it's possible, the difference in imaging circle sizes would allow shift of 10.8+ mm in any direction. However, space is tight. Mount a 24mm Elmarit on a Novoflex adapter and that 10.8+ mm reduces to 3.4mm in any direction because of the internal diameter of the bayonet, 35.9mm, and the diameter of the rear of the lens, 29mm; do the same with a CV 15mm and it's a little better at 4.4mm. There's then the question of whether the lens contacts in the G1 would make contact with the edge of the lens as you shift - they currently fill the circular space between the lens and adapter. Finally, the G1 sensor is deeply recessed and if the exit pupil is moved off axis, there's the danger of the sensor shrouding casting a shadow on the image.

dkCambridgeshire Posted February 6, 2009 Author Share #5 Posted February 6, 2009 Seems as if a shift adaptor is not really feasible ... thanks for the info. I ordered an M adaptor here Adapter Leica M - PANASONIC G1 micro 4/3 four thirds su eBay.it For 35mm SLR, Camera Lenses, Photography and hope to have it by next week. It seemed to be the most reasonable price. Buying direct from the Far East would entail additional VAT and duty and a Royal Mail admin/collection fee.

Hi Mark, As you know, I'm not an engineer by any stretch of the imagination. But 4.4 mm of shift, in that format, would be quite a lot. The latter issue you raise seems like it could be a problem.

TimF Posted February 6, 2009 Share #7 Posted February 6, 2009 Advertisement (gone after registration) Quite. The idea is great though, and I can confirm my old Nikon 35mm PC works fine with the G1 even at maximum shift. Using a purpose designed lens via two adapters isn't the same as using a regular lens on a special adapter though, sadly. Link to post Share on other sites More sharing options...

If so, are there any non-Panasonic 4/3 to MFT adaptors available? Cheers dunk Link to post Share on other sites More sharing options...
