You folks around here tend to lust well beyond what I can even imagine. I had to have a son in order to justify the purchase of my D70. That said I need some help. I currently have the kit lens (18-70, 3.5-4.5G ED) and the Tamron 70-300 LD 4-5.6 My question is this. I am considering the Tamron 28-300 as a walk around (fishing) lens and wonder what sharpness I am going to give up on the long end compared to the 70-300 I have now. I am well aware that the kit lens is superior in it's focal range but the 28-300 would eliminate switching lenses on those rare occations that I catch a fish and want my buddy to take a picture. Currently I leave the longer lens on for those times that wildlife pops out of the brush for a quick hello. Any help would be apprieciated. Oh yeah, no need to recomend those "mythical" lens like with fancy VR's in their name. I dream about them, but then I also dream about having an airplane, riverboat, sailboat......etc. So what do you think replace the 70-300 with 28-300 or not? I will be keeping the kit lens either way.
