Hi Everyone and happy new year! Thank goodness for 'The Beginner's Place' forum topic because I feel kind of slow not being able to figure this out. I just bought a Canon Rebel XTi and so far love it. I am a bit further along in my composition skills because I deal with a lot of imagery and simple photography as a graphic designer. Where I lack knowledge is in the equipment side of things. At first I thought I wouldn't need a new lens until later, but after experimenting with the EF-S 18-55mm lens that came with it I am quickly noticing its limitation especially when shooting on site, when I can't get as close to a subject as I would like with the effects that I want, mainly DOF and blurring the background. So now I am looking for a telephoto lens (is this what I need?) Now my dad has an old Konica with a telephoto lens. Is it safe to use that with my XTi? We're talking a 15-20 year old lens, possibly more... Thought I would ask before spending a few hundred on a new one. Thanks for your help!
