+ Sharp fine biler (with nikon d40)
+ Perfect focal length for macro in my opinion
+ AF works well and quickly, even when the AF limit is not set. A little noisy when the AF motor only works, not quite as quiet as Nikon's AF.
+ Excellent as a macro, can shoot really close and a whole new world opens up :)
+ Good and solid feel in control and focus ring
-Very very shallow depth of field at the closest focusing distance, it comes to putting the focus accurately and keep still, it can be a little tricky to get to the handheld but is fine after a little practice. So nothing specifically with this lens but most can be useful to know.
-Minimum Aperture 2.8 only at the focus to infinity, the focusing distance creeps up to 5.6. Maybe not specifically with this lens but can be useful to know. It takes some bright alto gain ISO to get fast enough shutter speeds.
Thinking of letting this replace my 50 1.4 and instead get something more wide-angle and bright. Very satisfied!
