Sigma vs Tamron Telephoto Lens Quality
I'm considering buying a Sigma 150-600mm Contemporary lens, and have also looked at the Tamron SP 150-600mm lens. The specifications seem to be similar, the major difference in aperture ranges which is not an issue for me. Does anyone here have some hands-on experience with either or both of these lenses, and an opinion on their overall quality? The price of the Tamron is about $170 less than the Sigma (at B&H), but I've had some bad experience with Tamron lenses in the past and I'm not sure if the savings is worth it.
Thanks for any help,
