I meant focal length and image quality...
There is no way a superzoom fixed lens "casn replace", be the "same", or be "more significant" than an SLR lens with a teleconverter. As I said earlier, IQ
is a product of sensor size, and the smaller sensor of a fixed-lens superzoom compact will always involve more noise and less light sensitivity. If you had to be able to stick a camera in a pocket, then that's one thing but if you are after quality images, you should really be using an SLR with the lenses.
And by the way, just about any image(of an aircraft) @ 1000mm focal length is going to look pretty bad, shooting through all that atmospheric distortion. Stick with 500mm or less. If you need more than that, you're not close enough.
