A:Answer290 additional focus points on the newer model RX100 V -- 24 frames per second on the V vs 16 on the IV -- Phase Detection AF is superior than the contrast detection on the IV. Check cameradecision.com for detailed comparisons.
A:AnswerHello. We actually don't have a DSC-RX100M5B. We have an DSC-RX100M5A and DSC-RX100M5. Both "M5A" and "M5" have a "/B" at the end of them to reference the color (in this case B is black). The DSC-RX100M5A is the newer body with an updated processor. -Nick
