Hi, everyone,
Currently, I am the owner of a Canon G3. It has performed for me very well thus far and I have been quite happy with the quality of the photos and the camera in general. However, a few of its limitations have led me to ponder the switch to a digital SLR, although I'm not 100% it will address my concerns, so perhaps you could offer some advice?
I am considering getting the 20D when it arrives, with the EF-S 17-85MM f4-5.6 IS USM. I figure this would be good for the sort of day-to-day photography I'm primarily interested in. (I guess I could be considered a "serious amateur") I think I'd probably add the EF 70-200mm f/4L USM and EF 50mm f/1.8 II shortly thereafter.
The first problem is the obvious shutter lag, which I know an SLR would help with. Having a slow shutter response time doesn't help when, for instance, the snake I'm photographing decides to jump out at me just as I hit the button.
However, I'm not so sure about the other problems. One problem I have is that the camera seems to be slow to focus at times. It seems as though it will sort of make a wrong guess on the direction it needs to go to focus, and thus fail or take a long time. If I try again, it will often get the focus correct, but this doesn't help when you are trying to catch pictures of people and/or animals in their natural setting. Would an SLR tend to focus more quickly or not?
The other issue I'd like to address is taking pictures where more zoom is necessary. I have the Canon tele-converter for my G3, however, pictures taken with it rarely come out well. They are usually extremely blurry and noisy. I'm wanting to take pictures of the wildlife that often finds its way into my back yard, which is why I got the tele-converter. However, animals like the deer only come out in the evening, when the light is rather dim. With the G3, I'm usually forced to use ISO 200 at f/2.0 and a shutter speed around 1/60s. Would the 20D and the EF 70-200mm mentioned above make for more focused, well-exposed pictures?
What it boils down to is that if a digital SLR isn't going to give me the ability to get better pictures in these situations, then it's probably not worth my spending the $2500+ (It's already questionable whether or not it's worth it
). I have to say that the prospect of having an SLR is very exciting. So as a final question, would there be a noticeable difference between the pictures taken with the G3 and those taken with a digital SLR such as the 20D?
Thank you very much for your help!

then you'd need a long tele so that you're sure they don't reach you.
