Those who think it's the camera that makes or breaks a photo is nothing but a hardware worshipping snapshooter or pretend-photographer troll. They have proved themselves no sort of photographer by claiming just so.

However a pro - a person who makes a living taking photographs - would not depend on a camera that *might* be capable of taking a good photograph. A .22 rifle *might* stop the charge of a charging lion, but the serious hunter would want to be better armed. -- Tony Cooper - Orlando, Florida

I think we have somebody close at hand who would be able to stop that charging lion with a pointed stick, and capture the "tack sharp, frozen in mid-stride" image of the event at the same time. -- Regards, Savageduck
