Yeah, one of those "help me buy my crap" threads. I'm going to treat myself to a macro lens for my birthday in March. I've been researching the various macro options, but wanted to get some input from folks here with practical experience. I have a D7000 body. I've been debating between: Tokina 100mm 2.8 AT-X: $489 Nikon AF-S 60mm 2.8: $559 Tamron 90mm 2.8: $449 (with $50 mail in rebate) The Nikon 105mm is more than I want to spend, my budget is about $600 or less. I'm leaning towards the Nikon 60mm, simply because it has internal focusing so the barrel length doesn't change. Has anybody else used any of these three lenses on a Nikon crop body? Care to share your thoughts/example shots?
