C1 with the hot folder is fairly fast on the a900. It is almost as fast as the Sony software which is not an elegant solution, especially on the output.
On lightroom the hot folder is painful slow and and not very suitable for fashion and beauty work. yet for my taste it has the best user interface and functionality, even slightly better than Aperture. the web gallery panel, with direct upload on ftp which can be done in parallel while you are doing other tasks in lightroom, it is hard to beat.
But so far C1 is still the best solution I have found for tethered shooting with the a900. It would be great if it could be as fast as with the Phase backs. Shooting with a phase back and c1 is a joy. You just plug the cables set a folder and it plain works. you plug and unplug the cable as you wish. turn off the camera. no problem.
On a different note, I have plaid with Phocus and the Hasselblad files and although it is OK, it made me appreciate C1 even more. C1 despite its little quirks, which are almost sorted out, gives a better experience for shooting and processing the files.
