I have seen a lot of confusing information about the Tamron 28-300 VC... some who have it seem to say it does well, and many who don't immediately jump in with "you might as well by a Rebel" type answers. I would like to get some experience from people that have actually use the lens on a 5D2 or 5D3.
I am trying to thin down my kit a bit, and after just buying a 5D3, I have on the shelf a 50D with Canon 18-200IS. I've also got a lot of L glass, including the 24-105, 24-70, 70-200, etc.. I use the 50D with that lens a lot as a carry around camera if we are going to the zoo, going to a family gathering, going on the boat, etc.. I don't want to haul around a bag of gear, and I don't want to be changing lenses on the boat when switching from close ups in the boat, to a bird, or to a wakeboarder. Plus, I'm not even usually operating the camera. The shots we get with the 50D combo are light years ahead of the iPhones or point and shoots. Are they L quality, heck no. But they are good for what we use them for... posting on Facebook or printing a 4x6 for the scrapbook.
I could certainly keep the 50D combo around for this purpose, but I'd really like to have the other benefits of the 5D3, and I'd like to cut down on the amount of stuff I have. If the 28-300 VC on a 5D3 can produce similar quality as the 18-200 IS on 50D, then I'd be happy.
Thoughts?
