Both look great!
The ov2715 especially is something we will look into, thanks for your suggestion. The housing is a bit bigger (10x10mm it seems) and will not fit in the case (our default sensor is 8x8mm).
For the ov5640, we do not provide power to pins 23 and 24 which are used by the autofocus. But a version of that sensor with fixed focus should work fine. Those two pins are no connect on our board. So you could also provide the autofocus power externally to these two pins. You will need to get the correct voltage (usually, 1.8V or 2.8V), which you can get from one of the header pin pads on the JeVois PCB.
