Hi TieuNgao, I try to shoot the fast jets at about 1/1250 sec, (propellor aircraft at about 1/100 sec), so that was set in the shutter priority mode. The aperture was then set by the camera, and the camera was in auto ISO between 100- 800 ISO, so that too was determined by the camera. Hope this explains, and thanks for the comments.

Thanks for the explanation, but I still wonder why the camera did that. For example, in one photo the aperture is f/14 and ISO=640. Wouldn't it be better if the aperture is f/7 (2 stops wider) and ISO160 (2 stops lower) for the same exposure? Did I miss something here?

Fair point TieuNgao, I can't answer that one. I guess that's the thing when you introduce an element of "Auto" into the mode, you just get what you get.

TieuNgao's point is a good one, if you are looking for any real advice. On a sunny day, best to set your ISO to 100 or 200. You can still shoot Shutter-Priority and let the camera pick the aperture. In bright sunshine, that ISO should be enough to do almost everything you want outdoors. The first jet pic was ss 1/1250, ISO 640, and the f-stop was only 6.0, so maybe you needed the higher ISO for that shot.

For slower shutter speeds to get blurry propellers on a sunny day, you have to keep the ISO as low as possible. You could even use a polarizing filter or neutral density filter to reduce the amount of light getting into the camera. Your helicopter was f29. Really high f-stops reduce sharpness, though at 1/125 and a 400mm lens, you're going to lose sharpness anyway from camera shake.

All that said, your pictures looks great! I'm still trying to figure out where you were when you took that first pic.

Hi Blade Canyon, thanks for the advice, any comments like this are a great help. Regarding the first picture, I was on the side of a mountain near where I live. The military aircraft do low flying exercises through the valley there. The Hawk that is photographed is based at a training facility near there.
