This thread definitely feels like deja-vu.
For me, manual gives me the most control over how I want a photo to look.
I have a good idea of what I want my DOF to be like and whether I want to freeze motion or not (streams/panning)
One (of many) thing(s) I'm not as good at knowing is what ISO is needed right off the bat when doing urbanscapes at night. Ideally I'd like to shoot everything at 100, but can't. Sometimes I need a couple of test shots to dial in the ISO.
I get people preferring exposure compensation when using Av mode, but that isn't nearly as intuitive to me as manual.
Certainly there are starting points and the camera can help me measure that, but rarely does the camera do exactly what I want it to do, and for me, manual is as (more) fast and more reliable then exposure compensation. Plus, those starting points help determine/teach me what the camera wants to do and therefore, what I need to do to overcome it.
Without a doubt, I'll shoot some things, using Av mode. But rarely are those shots that I consider to be stand-outs. They might be a really decent snapshot, but still, only a decent snapshot.
As skiers, many of the examples given are in regards to moving quickly through a backcountry lap or at the resort.
That's a fine place for Av and exactly what it is used for. But "we are moving quickly through the environment", meaning, we are skiing and taking pictures, not photographing skiing. There is a difference.
In many cases we aren't hiking a different ridge for a good vantage point or skiing an aspect based on sunrise or sunset light in those examples. If we have put that much effort into a shot, then I would argue that manual would be the way to go.
True, many wedding photographers shoot in Av for the same reasons given. And it is certainly do-able in the situation. But there are many wedding photographers and if they are worth their salt, they, at the very least, are probably using manual in the formals. And if they've been doing it a while, they are likely using manual in much of the other work. Or only have one camera set to Av. But just because many are using it, doesn't prove much. There are a lot of people doing wedding photography and they aren't all very good.
btw truth, lonnie looooves his sony NEX point n shoot (winkeez lonnie!)
I did get to handle one of those though, and while it's a great little camera and maybe a harbinger of things to come in mirror-less, it is far from my DSLR.
