Been a while since there was a post in here, but what do you guys think about getting the Tamron 90mm f/2.8 on a crop sensor? I shoot with a D7100, so the 90mm will effectively be 135mm. Will that still be suitable for shooting macros of corals? I'm guessing it'll be fine and if I want to shoot something larger I'll just have to back up a bit from the subject.
Looking to shoot some cool stuff soon
