Look at the optical diagram



and



these are quite different designs. It's true Metabones revived the idea on mirror-less first, but they can only patent their particular optical design. I actually welcome the competition.

.... just want native fov and dof ...


yes, thats the desire of everybody using the old lenses

did you ever compare a helios 58mm with a rokkor 58mm or a canon 55 1.2 ? the differences are huge, but significant...

I went out a bought several Nikon to EF adapters and Speed Booster works great with my collection of Nikkors:

55mm Micro-Nikkor f2.8
50mm f1.2
85mm f2

I'm looking forward to using some of my FD lenses.

Any chance of speedbooster for EOS-M->EF system.... That will help me in picking cheaper option instead of going to NEX-6..

you could just get a NEX-5N or C3 instead for less money. they have sensors that are just as good as the NEX-6 (and better than the canon).

Interesting.. I didnt know about 5-series... I was thinking that all 5-series are older models (I think, its NEX-5R which has same sensor as NEX6)... Only thing which EOS-M has, hot shoe... That I have found is very critical for any good system... But EOS sensor royally sucks for high ISO (just compared on dpreview again)... I may wait for drop in price for NEX6 for used one.....

5N is basically the same sensor but without the phase detect pixels of the 5R and 6. apparently the 5N scores slightly better sensor wise on DXO than the 5R, some say the phase detect pixels are slightly detrimental for iq...

you do need the 6 or 7 for a hotshoe. i've never used mine though, can't imagine using anything that mounts in a hotshoe on such a tiny camera.

I now have my NEX 6. Chinese Lens Turbo is on the way. I already have a Nikkor 50/1.4 AIS, debating between 28/2.0, 28/2.8, or 35/1.4 (AIS). A lot depends on which i can find for a reasonable price first.

How does this work at macro level (with macro lenses)... Does magnification ratio changes for macro setting...
This is more of theoretical question. If it changes, no use (as magnification can reduce only). If not, just a pieces of glass in between....

I've used the 43 on my 7 a few times. It's actually not as awkward as it sounds/looks as long as you're using a lens larger than, say, the Lux-M 35 pre-ASPH. And the shoe is far more sturdy than the lens mount, so it handles the weight nicely.

Magnification ratio is based on the size of your subject relative to your capture media, so a macro lens that is designed to go to 1:2 on 35mm FF camera will go 1:1.5 on a APS-C sensor (because you've effectively cropped away part of the image the lens was designed to produce). Since the speed booster changes the effective focal length, and therefore the smallest magnification ratio that can be achieved, your 1:2 macro will be closer to a 1:1.8ish.

If the smallest possible magnification ratio with a common SLR macro is what you're after, take the Speedbooster out of the equation and get a native 1:1 macro like the Contax S 60.

Thats not right... The lens which goes 1:1 on full frame will go 1:1 (same magnification ratio) on APS-xx format. APS-C cameras are nothing but the smaller sensor cameras compare to full frame... hence your capture area decreases, not the magnification.

Has anyone taken a chance with the chinese ones? The canon fd is very attractive at the moment seeing as how metabones hasn't announced one.

I am STILL waiting on a Fuji XF to EOS mount version.
I would LOVE to have one that has electronics, not for the AF, but to power the lens.
I have two Canon EF lens that focus via wire that I would LOVE to use on my FujiFilm X-E1, Canon EF 50/1.0L and Canon EF 200/1.8L
Those would be killer to use on this body.
