-3.5 is fine for Macro, don't sweat the 2.8 that much
-True-to-life colors
negative:-AF is garbage. It's actually humorous how bad it is.
-1:1 macro adapter is a bummer to use.
comment:Have you ever stuck a fork in a garbage disposal? That sound is roughly equivalent to this thing autofocusing.

I really loved this lens. I sold it because I needed some quick cash, but I've missed her from time to time. It's a fun lens to use, it's pleasantly sharp, colors are fantastic.

The build is trash, but to the lens' credit it is quite light. The barrel extends really far when focusing close, so be aware of that. You also need a proprietary adapter to go down to 1:1 full macro, so if you buy one make sure it comes with the adapter.
