The math is not very difficult. From the pics (if this is indeed a pic of the lens we'll see), would have a front element of about 12.5mm by my measurement. If the lens falls in the middle of the FL range indicated on an older Q roadmap, then it should have a FOV EQ of @ 92mm for the Q, which works out to @ 17.5mm in actual FL. With this FL and entrance pupil size, this works out to @ f1.4 max aperture.

I think this would be an acceptable spec for most users, and if it's a 1:1, all the better. The only problem with looking at FOV EQs with macro lenses is that the actual FL is what counts for MFD/working distance at 1:1. Working distance will likely be pretty short, but the low weight and small size of the lens/body should allow for easier handling than a 1:1 DSLR setup. Don't forget that the Q with a 1:1 lens shows almost a 4:1 apparent magnification (size of subject in relation to the image frame), so this is a pretty extreme macro setup at MFD. Working distance could be improved by pulling back and shooting at a 1:1 apparent mag.

I think that it's a good idea to announce and show prototypes of this lens even if it will be a while before actual introduction. It gives current Q system owners something to look forward to and potential Q system buyers IMO, this lens and the 06 tele zoom should have been among the first available for the Q system (as well as the K to Q adapter) since they dramatically illustrate the size differential between the lenses (and therefore the total multi lens system size) of the Q system against any other ILC system.

size of the entrance pupil is not the same as size of the front element (again look at the 01)

but yes ... technically its possible .. with a nightmarish image quality at the boarders.
