Got it less than 2 years ago but only used a few times. Good lenes for macro as well as portraits. AF speed is quite decent for a 3rd party macro lenes. I pick this lenes over the original Nikon because I more reviews that states that it performs better over the original. Never regret getting this lenes. Release this lens because I'm changing system. You can check out the lenes at my studio before you decide if you want to buy. Kindly book an appointment. Thanks!
