Re: PanaLeica 10-25mm F1.7 Questions

If possible, could you please evaluate this lens on an Olympus EM1-II and on a BlackMagic Pocket Cinema Camera 4K? I think performance on the latter may be of considerable interest to videographers, as on paper the lens looks like it may be ideal in the ultra-wide to standard focal length area. Is the knurling on the focus, zoom and diaphragm rings sufficient to attach a side control device such as used in manual follow focus on a video rig? Others have already asked about focus breathing while zooming, clearly important in video.

For still photographers, a comparison with all the primes covered in that focal length range would be very interesting. Although clearly bulkier, could it replace, hopefully with even better image quality, lenses such as the 12mm f2, 17mm f1.7, 20mm f1.7 & 25mm f1.8 (maybe even the 25mm f1.4?) ? If the answer is "yes" to that question, then the size/weight becomes less of an issue (but not the cost for those already invested in the above lenses).

Also, functionality on Olympus MFT cameras will be very important. I would expect it to work well on Olympus cameras, as other Panasonic Leica lenses do, but it would be very helpful to have that confirmed.
