@kokfa

Alas I cant afford Leica glass...I once passed up the opportunity to get a Leica R 2x teleconverter that was going for about £40 but thats the closest I got.

Sorry, I'm not an expert in lens and adapters, but in this videos I assume that no adapters are used? So is it true that all canon lenses can fit onto the sigma SA mount? And will it lead to any loss of image quality or autofocus function? :)

Thanks!

@recbo You sure your not using M42-PK adapter by mistake?

M42-PK adapters are several mm shallower than M42-SA adapters and they have open bottoms which allow the AA pin to touch the dust protector on the camera.

You might not be able to resell lenses with clipped pins as the pin can be essential or the lenses aperture mechansim may not work correctly on some cameras.

Use a proper M42-SA adapter which has a flange built in to compress the pin and you will never have to clip AA pins again!

Well now the SD1 has been announced and with an "accuity" of 46mp on tap it will beat even medium format cameras.

You only get autofocus with Sigma SA mount lenses or Canon EF lenses that have been converted to SA mount...All other lens options are manual focus only.

Dont worry Barry, there is no sound on the video anyway. Sigma lenses can be converted from Sigma SA mount to Canon EF mount and visa versa so you could convert your 17-70 to SA mount no problem but you would need a donar SA mount lens to supply an SA mounting plate and contact block...But that seems a bit pointless when you could simply buy that lens in SA mount.

, but you will need

The SA mount is based on a bayonetless Pentax K mount. (Which is why the rear lens caps are interchangeable between the two lenses.

I recently got hold of a Canon FD 85mm f1.2 L and am converting it to SA mount...Converting the aperture dial to fully manual operation is very simple. The moving rear element and the fixed rear element are both missing however so I'm looking for replacements before I can finish the job. I'm wondering if replacing them with rear elements from the current EF version would be possible...If it is, then it should negate the need to machine the rear of the lens down to retain infinity focus.

[g7vgg]

As the Canon EF & Sigma SA mounts share the same 44mm registration distance its not possible to make an adapter to mate one to the other whilst retaining infinity focus unless your prepared to put up with at least 1.5x or more extra magnification with each lens as the only way is to modify a Canon EF or Sigma SA teleconverter to make an adapter. You could convert each EF lens to SA mount though, and whilst that is reversable alas, its not a simple, quick job to keep swapping the mounts over.
