Stupid thing i didnt type it as written. I think you get what I am saying. Heaven help us if they make a 50 to 500 lens. It will need and handle as would a 500 fixed lens. While talking about long lenses they usually have tripod mounts. Make up an ad...
One rule for zoom lenses they must always be thought of as being their longest focal length. E.g. 25 to 50 handles like a 50 50mm. 100 to 400 treat it as a 400 50mm lens. Use the zoom lens which will just do it all with the one lens if you can.
