I decided to use the A mode in my camera for a change, only because so many people say that manual is not the only way to shoot and occasionally you need to use the other I tried. Normally, 100% of the time when I shoot in manual I make sure that my shutter speed exceeds the focal length of my lens. So if I am shooting with my zoom lens ( which is most of the time) and I have it set at 300mm then my shutter speed will no doubt be set at 1/320 sec. or above, leaving my ISO as low as possible and my f /stop as wide as possible for the shot.

In aperture mode of f/5.6 the camera chose to set the shutter speed to 1/40 sec. even though the focal length of the lens was set at 150 mm. So what happens when the shutter speed is lower than the focal length and no tripod.....distortion. While it is not so noticeable in the above photo, it is definitely noticeable when the photo is enlarged.

I know where I focused (eye) but when I pressed the shutter release button apparently something moved. So the question is ......should the f/stop been increased or........?

I am open to suggestions but truth be known I am more inclined to stick to manual mode. Sure there are times that I have lost a shot because of the time that it took me to set everything up, but in the long run I feel like I am in control or am I? :)

I use A mode quite a lot. What I do is set my preset of the iso open. I have 3 presets, one stands on iso 200 to 800, the second on 200 to 1600 and the last one 1600 to 6400 iso. Can change between them  if shutterspeed gets to slow. Going for a bigger apperture gives you a faster shutterspeed. Like f2.8.For no movement I use S mode,if you have to be fast.

Unfortunately, I don't have an answer to your question, but I hadn't realized the correlation between zoom length and shutter speed and distortion. Glad I read your post, because now I have something new to think about! For what it's worth, I get a lot of wonky results when I use A on my camera too. I love this photo though!

Manual or shutter speed or aperture priority for sure.

I see someone can't make a decision ;) I presume you mean all of the above but definitely not auto ;)
