.. as soon as you buy something, the next generation is released the very next day. Having just bought the Sony RX100 mark IV, the RX100 mark V has been announced and is due out this month.
That said, while the mark V introduces even faster auto focusing through 315 AF phase detection, with auto focusing reduced to around 0.05 seconds, it’s also £400 more expensive than the mark IV. Plus the mark III is continuing to sell just as well. The mark V doesn’t offer a better electronic viewfinder, nor does it offer a touchscreen. What the mark V does that the IV does not – 24 fps continuing shooting in RAW. Impressive for a non-DSLR. Otherwise the specs remain mainly the same as mark IV.
The mark V’s 4K video system has improved, but I reckon they’ll still only limit it to 5 minutes per clip given how small the camera is, and how hot it’s going to get to be able to process the video. I have a solution to that, but I won’t reveal that for a little while as yet.
In any event, best strategy is to let others tinker with the new model for a bit to see how things pan out over a period of several months. I’ll be perfectly happy with the mark IV for a couple of years. By the time I’m ready to upgrade, the mark VI or VII will be out that will probably make marks III, IV and V look like tinker toys. Or maybe I’ll upgrade to DSLR? We’ll see.
