Sony RX100 Continuing to focus

[drd1135]

Hey folks. I have a new RX100 set to AF-S and it seems to continue to focus on its own when I just point it at anything. I also turned off face tracking. What have I missed?

Which setting is the mode dial on? AF-S operates only in the PASM modes.

The 'Welcome to Sony' sign. From how I remember it the AF system on your RX100 is always on duty, in either AF mode, same as on my NEXes, unless you set it to DMF mode (saves some energy) but then you can't use the control ring for anything else but manual focusing.

You're right, but this is overcome by setting the centre button function to AF/MF control toggle. This allows focus/recompose shooting, and the control ring is available for the zoom function when the DMF has been toggled to OFF. The only real disadvantage is that after toggling to DMF for focus/recompose shooting, one needs to remember to toggle back again.

Thanks. I don't actually mind it focussing but I assume that will drain the battery much more quickly. I bought it for my wife and she'll probably just turn it off between pictures. Impressive IQ, BTW.

Again same as on my (ex-)NEXes, I've just been too lazy to list all those options. The issue I'm having with DMF is that it doesn't allow manual focusing unless the AF has locked first but then my (ex-)NEXes don't need that much contrast as my X-Pro1. The X-Pro though does AF in MF mode and allows manual intervention at any time so I just leave it in MF mode most of the time.

Nothing to worry about, just grab a couple spares.

Impressive IQ, BTW.

Some weeks ago I had the Mark III for a couple days, played with some RAWs and couldn't believe it. It's even better but I have that ongoing strange relationship with my little Fujis.

It's a neat little camera. It is really small in the hand. If it were mine I'd get a grip of some kind. My wife will really enjoy the small size and the nice array of automated features. She's especially keen to see how well it does for night shooting. It will get a work out next week at Disneyworld.

Hi , I don't know which RX100 you have, but on my M3 you go to:
Menu
Second tab from the left
page 2
lowest option: Pre-AF.
So you can switch it off. (I did)

Hope this helps.

Thanks. I have version 1. I'll check, however.
