looks like a moth

SinnerBuyer, the guy writes about using compressed air to make it clean again. As a pro you're expected to be able to take care of your own stuff.

chiggy, SHARP!!! OW!

dark lenanza, actually P mode makes a lot of sense especially for landscapes, or if I assume he was using the 70-400mm and he'd go between a 70mm landscape and a 400mm sports shot.

Program Mode works like this:

1) Set aperture to brightest and ISO to lowest of Auto ISO range (e.g. 300mm F2.8 ISO200)

2) Calculate reciprocal of focal range as your "needed shutter speed"

For an APS-C body, 300mm * 1.5 = 450mm equivalent, so 1/450s is what is used. But that doesn't exist so they round it up to 1/500s.

3) If shutter speed is faster than "needed shutter speed", stop down the aperture so that the shutter speed is correct.

Let's say at 300mm F2.8 ISO200, it meters at 1/8000s. So it picks F11, so it becomes 300mm F11 ISO200 1/500s.

4) If shutter speed is slower than "needed shutter speed", increase ISO so that the shutter speed is correct.

Let's say at 300mm F2.8 ISO200, it meters at 1/30s. So it increases the ISO to the maximum defined by Auto ISO, let's say ISO1600 - now it's at 300mm F2.8 ISO1600 1/250s. Sure, it's not able to hit 1/500s... but that's where Super SteadyShot helps!

As you can see, Auto ISO prefers to use a good shutter speed to avoid having to use Super SteadyShot much.

On the A900 however, Auto ISO is a bit more relaxed... at 135mm for example, it picks 1/100s as the "needed shutter speed" instead of 1/160s.

I know a lot of you love Aperture Priority, to maximize bokeh, but here's an example where Program Mode works great:

Shot at 135mm F10 1/100s ISO200 on the A900.

If it was shot at F1.8 you certainly would not be able to make out any people, and it would reduce the story-telling aspect of the picture. Not that there is much of that, here...

ryzan76, I like how it looks like it's sneezing!
