jaapv Posted February 19, 2013 Share #721 Â Posted February 19, 2013 Advertisement (gone after registration) Wilson, I was referring to the flanges that are sold for coding lenses. They have quite a good reputation. Â http://www.ebay.nl/itm/6-bit-flange-adapter-for-Leica-M8-M9-lens-28mm-90mm-/360389035614 Â Â Â Â . Â Jaap, Unlike many of the chinese adapters, Amedeo's are machined from very high quality brass, which is then hard chromed for longevity, rather than quite soft aluminium that many of the chinese adapters use for both male and female bayonets. I know the chinese M to micro 4/3 rd's adapter I have, is horrible and only fits where it touches. In due course, I will probably get a Elephoto or Rayqual one to replace it.

wlaidlaw Posted February 19, 2013 Share #722 Â Posted February 19, 2013 Wilson, I was referring to the flanges that are sold for coding lenses. They have quite a good reputation. Â Jaap, Â Those would not work for the way that Amedeo has designed this adapter to make it very rigid for long lenses. This is the reason he has used male and female M bayonets with tubular flanges, which are a tight fit over the extension tube and held in place by three Torx screws. This is much more robust than a face to face connection with a standard flange, held in place by four M1.7 countersunk screws, which would then carry any bending load across the adapter. This is the reason, as I explained to Luigi, that there was no off the shelf bayonet available. Â Wilson Link to post Share on other sites More sharing options...
jaapv Posted February 19, 2013 Share #723 Â Posted February 19, 2013 I see the reasoning. However, somehow Leica has the flat flanges for even the heaviest R lenses. your design seems to me to be more robust. Link to post Share on other sites More sharing options...

I understand  (even if when long are REALLY LONG... is the lens that supports the body, not vice-versa... ) Welcome, dear visitor!

wlaidlaw Posted February 19, 2013 Share #726 Â Posted February 19, 2013 Luigi, Â .....but think of the weight of an M240 with multi function handle and EVF-2, all hanging off the back of a lens. That is quite a bit of leverage, particularly if you have your hand on the camera as well, maybe moving the whole assembly round on a tripod head. I felt it was just too much leverage for 4 x M1.7 screws, with very fine threads, so agreed the tubular flange design with Amedeo, where the whole diameter of the locking screws are in shear, not just the threads in tension.

k-hawinkler Posted February 19, 2013 Share #729 Â Posted February 19, 2013 I think it's more the force one can put on that connection when controlling a large lens on a tripod by positioning with the camera. Link to post Share on other sites More sharing options...

This lens appears to be quite rare to non-existent on the used market. Any thoughts on what a good copy would cost?  Thanks.  John,  I too have been put off by the current prices for this lens. My current thinking is maybe to re-acquire a Zeiss Contax CX/Y 28-85 zoom instead. The later Japanese MM model is better than the earlier but usually more expensive German made AE model. I used to use one of these on my Contax RX and RTS2 cameras and it was as good as I could wish for, with a very small amount of softness and distortion at 28mm. More data here: The Carl Zeiss Vario-Sonnar T* 28-85 mm f/ 3.3-4 C/Y Lens. Specs. MTF Charts. User Reviews.  Now for the downsides: It is a one touch zoom, which a lot of folks don't like. The adjustment for the focus to remain fixed while zooming is tricky and needs a real lens expert to re-adjust if it goes wrong. I would not buy a lens which did not stay in focus while zooming, as the adjustment cost would make the purchase uneconomic.  The major issue at the moment is that all the available CX/Y to M adapters either bring up the 35/135 frame lines or the 50/75 on an M body. I have got Dirk Rösler to explain the situation to Miyamoto San, who makes the excellent Rayqual adapters. He says he understands why we would want an adapter that brings up the 28/90 frame lines but has no current intention of making a run of his CX/Y to M adapters to do this (why not???????). It is not a particularly easy alteration post manufacture, as you have to add metal onto the frame lines tab. At the manufacturing stage, it would be a very minor change in the CNC file to cut slightly less metal off the framelines tab to arrive at 28/90. I suppose Malcolm Taylor could alter the adapter for me and mill the coding pits.  Wilson Link to post Share on other sites More sharing options...

marknorton Posted February 27, 2013 Share #739 Â Posted February 27, 2013 I paid more for mine than I would have liked but it is mint and I was slow off the mark. Still, it was less than a 35mm Summilux. Even if Leica was to introduce a replacement, it is hardly going to be cheap. Link to post Share on other sites More sharing options...

Â Given Leica's experience with the Tri-Elmar lenses, it might be feasible to reintroduce them in less mechanically complex forms for use with live view and with the full zoom range.
