Hi guys, I am new to the forum and have been messing around with my DLSR 350D for a little over 2 years. I recently bought a used Tamron 28-300 zoom lens off of craigslist. I wanted a lens that would suit just about every need that I had at the time. Below are a couple of the pictures I have taken with the new lens. Recently I have been thinking about upgrading to the 40D and using the kit lens that comes with it. What do you guys think, sell the 350D and upgrade to the 40D or, keep the 350D and buy some better glass? I take about 4-5000 pictures a year. Thanks for any help or suggestions.
