i use it heaps! I do make an effort to use this lens though. I believe that using a 50mm as much as possible will make me a better photographer. It's just too easy to reach for the wide angle!

i have avoided getting a wide to short tele zoom for this reason.

Hi,

I'm new to nature photography and also to digital.(just got a 40D). Anyway I am

interested in how people make use of the AF-on button(or *) for nature

photography. During my first attempt at bird photography last week i found it

hard to actually keep the shutter button half depressed during AI servo focus

and kept either taking a photo when i didn't want to or losing pressure on the

shutter completely. I also wanted to shift between One shot and AI servo focus

more easily as bird are often flying and then still while perching.

I believe a have found a solution but have not yet put it into practise yet and

would like to hear other peoples opinions. I set the custom function so that

the AF-on button acquires focus and metering while the shutter button meters

only. That way i can easily keep the button depressed with AI servo tracking

and can keep the camera on AI servo and simply press the AF-on button for an

instant to get focus on a static subject and then prees the shutter to take the

photo. no need to switch to one shot focus.

Does this sound like goos use of the AF-on button? I'm also interested in other

things people find usefull about this function.

thanks,

edi
