I concur. The main camera is superb, and does pretty darn well in low light without a flash, too.
The 735 is 4G and single SIM whereas the 730 is 3G only and Dual SIM.
The 735 is the best smartphone I've ever own. Not that I've had that many, but it trounces every Samung Galaxy I've owned, and compared with the Moto G 4G which has identical processor, gpu, RAM, storage space, and screen resolution, well, the 735 has superior cameras, stability, screen, speed, and also has NFC.
I'm hoping to buy a 2nd 735 - just waiting for the price to stabilise here in the UK - as it is one amazing phone for the price point.
