| p.1 #13 · Nikon D2X - How do you use your AF ON button? |
Anyways, I tried it for a while just to see what all the frothing fanatics here were talking about and how they love it so much and found it really pointless, and obnoxious.
There's quite like nothing like pressing two buttons to take 1 photo.
Your snark is entertaining, but I find the AF-ON button invaluable. There's nothing I hated more than finding perfect focus only to lose it again the moment I touched the shutter release button again. Especially in situations where I'd had to hunt for focus in the first place, the last thing I need is the camera and lens hunting for focus repeatedly once I've already gotten it dialed in. I primarily do portraits, and I use AF-ON in conjunction with continuous tracking. I focus on the eyes and hold AF-ON while recomposing. Then I can release AF-ON and fire away without worrying about ensuring perfect focus again and again with each capture.
I don't take people photos, so maybe I just don't get this, but how the heck are you 'hunting" or losing focus of a person in a portrait setting? Then you mention getting perfect focus and firing away. Your subject is moving to fast for a correct AF lock or they're suddenly not moving at all and you can take a bunch of photos?
Anyways, I did notice that I never hesistate to set the C-S-M switch to M and just start to focus manually when the AF is just going to waste time and be annoying, like when shooting though a window or with junk in the way, like a fence. If the AF can't cut it, I turn it off, like matrix metering. When it's wrong, it's very very wrong.
For moving subjects I suppose it's the same. For the first shot of each burst, I suppose it's the same. But if both my subject and I are stationary, I like the ability to only focus once and shoot several times. I hated it wanting to reacquire focus with each shot with the default setup.
