Returned the lens for exposure errors. It was and excellent piece of work beyond that issue.

Summary: Lens was tight, bright, and accommodated macro views. It was the right size and permitted reasonable filter acquisition. The manual focus clutch feature is great in a small macro. Problem was the one I received exposed at 1.5 to 2 times over normal, creating washed out images. I returned it. If I was assured of a good one, I would likely buy it again.
The best normal macro available at the time of purchase

Summary: There was none available at this focal length for DX cameras when I shopping for this lens. This lens is super sharp and well built. Although not a big fan of push-pull focus ring I haven't had big problems with it. Lens hood for this lens is only for screwing on filters and not for others reasons that we typically use lens hoods for. I have not tested Nikon 40 2.8 Macro and can't speak for which one is better.
Summary: This lens is great, the image quality is very good, the colors are nice and vivid. the snap thing from manual to auto is easy and practical when you get used to it. the only drawback of the AF/MF switch, is that sometimes (not very often)(when the camera is in the bag)the ring gets stuck half way, between manual and auto focus, so you have to check the position of it. This is why i dont rate this lens five stars.
Summary: On my search for a normal or little wider lens in the up to $500 range, I tried the Tamron 17-50mm F/2.8 (non VC), the Canon 28mm F/2.8, and the (manual) Voigtlander Ultron 40mm F/2.0, before ending up with the Tokina. I tried two copies of the Tamron, each with severe quality issues (possibly due to sub-par protection in manufacturer box). The Canon was just OK and most importantly failed to reach infinity focus.
Summary: Overall, this lens will get you fantastic results, but the design of it will leave you wanting a little more. I own a couple of Canon USM lenses (15-85 and 70-300 L) and this lens makes it difficult to get used to the focus handling. Even compared to Canon's common AF micro-motor lenses such as the 18-55 kit lens, 18-135, and 18-200, the Tokina is noticeably louder. But it is less noisy than the Canon 35 f2 which sounds like a box of angry mosquitos.
Great Prime (normal) lens for APS-C DSLRs with Macro capabilities

Summary: This is a 35mm lens suitable for Nikon DSLRs with F mounts. It is designed for the Nikon line of APS-C sensor cameras from their Pro-Sumer line like the D90, D7000, D5100, etc. As such it is like a "normal" lens with a 35mm equivalent of about 53mm. This is also a macro lens and probably the least expensive way to get into macro photography on a Nikon. Nikon's 105mm Micro lens is much, much more expensive.
Summary: I bought this lens because it was extremely cheap and looked like it would work for a set of macro shots. It is definitely a sharp lens and the shots ended up coming out great. you can literally touch the object(in this case it was a ring) with the lens, and it gets it in focus. This would be good for some smaller gigs, and to experiment with macro photography.
Summary: I was so excited to receive my first copy of the Tokina 35mm f/2.8 Macro for my Canon T2i a week ago. This would be my second lens after the 18-55mm IS that came bundled. I immediately attached it on and took some sample shots. After about ten shots on Aperture Priority Mode (taking sample shots in all the aperture settings), the camera had a communication error with the lens.
Summary: Thie is the first lens I bought for my new Canon 7D. I had the 50mm but I am finding this lens a lot more usable. Also, the 50mm was so small and just didn't feel the same on the new camera. I love taking pictures of people so this is a useful tool. I will add more lenses but, at this time, I'm enjoying this lens. Worth the price.
