Whereas the PGM can deliver 100, 000 bases of DNA code in a two-hour time frame, plus sample preperation, the MiSeq can deliver 250, 000 in eight hours, including prep time.
Speaking of the sensor, we got a chance to do a brief comparison between the A99 and Sony's RX1 compact that packs the same full-frame CMOS. As you can see in our sample shot, the sensor does its job regardless of form factor -- you'd be hard pressed to determine which pictures were produced with the DSLR and which came from the compact camera.
