I own a Rebel XTI and have been a Canon loyalist for a while but lately have gotten into some professional work, mostly shooting outdoors and sometimes in lower light. I am doing a lot of active portraiture and need about 200mm of telephoto but use my wider range at about 50mm too. My question is; What is one of the most versatile and best quality lenses out there that would work well in various situations. I've been looking at some of the Canon L-series and the ones that seem most versatile are too expensive for me, but if I am gonna spend a lot on a lens, which lens is best for the least amount of money, or where is he best place to buy lenses with the best deals? If I could spend 500 dollars on a lens, which one would be the ultimate? Where should I get it? What about the Image Stabilization technology? Are there any places that sell used or refurbished lenses at good prices? Just some purchasing advice, please! Thank you so much.
How about a 70mm-210mm f2.8 (or equivalent) and a 50mm f1.8.
But if you don't need the 2.8 fixed aperture, you can probably save $1000 by getting a slower zoom.
Be careful where you purchase. If you find a better price than B&H, it's probably gray market and doesn't come with a Canon USA warranty.
Adorama sells refurbished gear, I picked up a lens(just ordered a refurbed flash a couple hours ago also) from them and couldn't tell it from new aside from the box it came in. Heck, I'd almost rather buy refurbs all the time knowing that a tech has checked everything out and it's good to go compared to it just coming off an assembly line.
You can also by used from Adorama/B&H/KEH, I've heard that KEH underrates some of their gear occasionally.
