Teleconverter Canon

Will any teleconverter work with my lens?

I’m getting a Sigma 17-70 2.8 lens for my Canon XTi. If I get a teleconverter in the future, what do I need to do? Will it automatically fit?

I’d agree with the above in that it doesn’t make much sense to use a teleconverter with that lens. Although you double (or 1.6x) the focal length, a teleconverter exaggerates any faults with the lens. Maybe if you keep the focal length at 70. But a teleconverter is one of those things you use if there are no other options, but there are fairly inexpensive telephoto lenses out there, which would be a much better solution. The jump from using a 200mm lens to a 400mm lens in price is astronomical, so people get a teleconverter to use in that situation if they REALLY need that distance.

Try out the 70-200 4.0L. It isn’t as fast as the 2.8, but it is also quite a bit less expensive and much lighter. The 80-200 isn’t being manufactured anymore, but I’ve heard good things about it so if you see one used pick it up. I used a teleconverter with my 70-200. The teleconverter itself wasn’t particularly expensive, but the trip I used it on was. I came back with exactly two workable photographs while using the teleconverter. The slight change in focus just wasn’t worth it to me as well as the lost light.

However, to answer your question, yes, physically I think the lens will fit on the teleconverter as long as you buy the canon lens. If it would actually work well with that lens, I don’t think so.
