A-fs/A-fc

[madmardle]

I understand the difference between the two focussing modes, and why it's better to chose A-fc for moving subjects, but what would the dis-advantages be in leaving in that mode for portraits, landscapes etc. I'm just thinking of having less to do and remember, or have I missed something obvious.

i wouldnt see any big dis advantage for landscapes but for portraits it may keep hunting unless camera and subject are both very still

OK thanks, I knew there must be a reason, I just couldn't think of one.

I dont think you can focus and recompose with AF-C?

You can if you use rear button focusing, and disable focusing with the shutter release

Or use AF Lock button although this will also lock the exposure if you're not in manual mode.

Without digging out my manual, does my Nikon D50 have a back focussing button?, although as I shortly hope to upgrade to a D90 I assume they do

AE-L/AF-L button can normally be configured to do the focussing. If not on the D50, definitely on the D90.

the d50 is in the menu. pencil image then #14, and then it's the bottom option.

this thread has reminded me to charge my battery for tomorrow, thank you.
