These were taken with my T2i and Tamron 90 mm macro. I tend to grab that camera whenever I want to take a few quick shots. I own the non-L 100 mm but I think the Tamron is a very good lens as well. In fact, it's been the only lens mounted on my T2i for probably 2 years.
How do you respond to the following compliment: Hey, that's a nice photo, you must have an expensive camera. It's a compliment in that they like your photo enough to comment on it, but it seems like they are giving all the credit to the equipment used and none to the person behind it.
