so, "all things being equal" autofocus speed is a function of the lens, not , the camera body. What about aquisition, Common sense ( if there is such a thing :-) ) would tell me a body with more autofocus points would AQUIRE focus more quickly, but what about sensors ?....do sensors make a difference in focus aquisition ?
The reason for my question. I hope to someday actually have time for this hobby and I really enjoy photographing birds, especially "in flight". I currently have the 450D body and a 100-400L series, focusing on a flying bird in a nightmare, I don't know if going to a faster prime would help or not ( if I could afford one ), so I was curious if in the future I might consider a new body.
thanks for your thoughts
regards,
mike
