| I think another benefit with the 55-300 will be distortion. I've not experienced the 28-300 or 18-250, but I have toyed around with the Nikkor 18-200, and I'm really not all that happy with the distortion. If the 55-300 keeps distortion to a minimum and acheives sharp images above 200mm (a traditionally 'soft' spot for most consumer zoom lenses, granted that some are better than others but they're all a little soft) I would be willing to shell out ~400 for it. |
