A shame the NEX cameras don't report anything below 1.0, you should actually get 0.9
Try Aperture priority, and you should find "1.0" at the two widest settings, one of them is actually 0.9
That is how it worked with my Canon 50 mm 1.0 L, but that lens with the SB is another story.
Has anyone tried an Nikon F-mount with Nikon to Canon converter + SB ? I can't seem to wait for a proper F-mount version and besides all my lenses are MF (AI/AIS)

It works!
I have the Planar 50 1.4 ZF.2 on it right now, and will bring it with me today and see if I can get a real photo with the "look".

I'd mentioned that the 58/1.2 Rokkor wouldn't allow the shutter to open unless I wiggled it a bit (the mount to the SB is slightly loose), a 24mm VFC Rokkor that Jim converted for me, as well as a 24/1.4 FD that I bought converted and appears to have one of Jim's mounts (wide adapter) sit firmly and I can't get the shutter to open at all. I would guess that it shorting a couple of pins that the firmware doesn't like. Tonight I'll tape the pins to see if they start working. If they do perhaps Metabones could fix that with a firmware update (presumably they short the same pins on a Canon body yet don't affect it). By the way when I go into the menu it won't allow me to switch the Release W/O lens to ENABLE. I keep this option on ENABLE and when I put a lens on that's OK it defaults to that....Show more →
Nah, not firing is the correct behaviour here. It forces the user to tape the contacts and prevent a short circuit from taking place. Why would any 100% mechanical lens want to make contact with the electronic contacts? (Pun intended.)

The adapter really looks short, it feels more like using an M adapter than an N adapter.
The design is also very nice, one end matching the mount and the other matching the lens.

Sweet. Thanks for all the test shots, very insightful.
However, what I would love to see is how the total image compares between the SB on a NEX and the same lens pared with a FF sensor - ultimately I think this is what will matter most to me. If I want sharp corners for a landscape my OM-D can give me that in spades with the current m4/3 line-up, but I want to see how out of focus areas look. Will it have that same "pop" and subject isolation that a larger FF sensor provides?
For example, this is a shot I took the other day with the 6D and Zeiss C/Y 85 2.8 wide open. What I want to see is whether the SB will yield the same "look" with the same lens....

Thanks for all these details on lenses fitting the SB.
Are your CY adapters ones with electric contacts?
If so, are adapters with electric contacts better in order not to short the adapter?
John
A SB test thread has started at mflenses, so far with similar but less detailed OM results, http://forum.mflenses.com/metabones-speed-booster-test-thread
John, no, none of my adapters have chips.
Bo, I guess that makes sense, I just wonder why they work OK on an EOS body.. any idea?
Michael, I have been out all morning taking paired shots (much of the time) with a 1Ds3 or 5D2 and the same lens on the Nex7. I'll download tonight.
Well you mentioned you had to wiggle the lens a little bit, so I guess the metal is just dangerously close to the contacts on EOS but actually makes contacts on Speed Booster. (They are spring-loaded pins, so there's got to be variations between different springs.)

Good news: the upcoming m4/3 version optimizes for the smaller image circle required and had sharper corners.
The takeaway from the test image crops, is that you don't get the same "pop" from what is in focus. The SB adds a glow, some USM (8 px 25%) will be necessary to try to make it look like without the SB Adapter. Note that this is for Category 1 comparisons (vs same lens on FF camera).
Infinity focus is indeed a problem with the Planar 50 ZF.2 and Novoflex adapters. The adapter with aperture lever is worst
I uploaded some images @50% (res, not crops). LR4 default inport, no sharpening on export to jpg.
I have a few to add labels (the airplane, brainfart on lenses and setting at the moment).
Labels say it all I hope, all Nex7 with SB
Lenses used; Leica R 28 and 60 Elmarit, Rokkor 58/1.2 (only worked for a while) Rokinon 35/1.4, C/Y 18mm, OM 90/2, Canon FD 35mm T/S
I hope I got the lebels right I'm doing this in a hurry. If some are wrong (eg apertures reversed etc) I'll fix later today or tomorrow.
Heading out soon for some more comparisons. http://www.pbase.com/mike_broomfield/speed_booster&page=all

PS. 1st couple of photos with the Nex 7 I didn't notice I'd bumped it to Auto ISO so they are at 800.. grr...

Thanks for the photo upload. I have noticed a warm cast with the SB + Nex7 as compared to the neutral color of the 1ds. Is it just a WB issue or they're on the same settings?

The "glow" you mention was evident in some of Roger's images from his LensRentals review of the SB. If its easily correctable in LR then it won't bother me, but the "glow" that was present in his images seemed like something that might not be so easy to fix.
Michael, I added 2 more pairs from the 35/1.4 Rokinon at the front of the gallery. The photos of the fishing boat doesn't isolate very well as it's so far away, but the tail of the airplane does. There is also a pair of the boat taken with the OM90 at F2. I don't care for the bokeh from the 90/N7 combo and was surprised to see it.
