Having long hesitated between a macro lens and a 300mm quality, today I do not regret my purchase with this beautiful stones, with which I enjoy and makes amazing photos. Me which previously was at best the proxyphoto, literally the difference is obvious therefore that we pass to the ratio 1: 1. I also hesitated between taking the unstabilized version thereof with a stabilizer (100 difference between the two), according to my extensive research on the Internet and the different opinion, it is best to take this one , I can not compare the two goals but for me for 100 more it is better not to take a risk and choose the stabilized because it is an investment for the long term and it is desirable to protect themselves from surprises (remember hostess of the stabilizer when you are on tripod if it is the opposite effect to that desired will happen). The only flaw of this goal is that the autofocus may tend to spin endlessly, especially in case of lack of light, I always go into manual to counter this phenomenon, and then I really get what I want to be in this mode. PAD is ultra quiet with its new ultra-sonic motor (compared to 90mm Tamron available only there a short time, which made him an incredible racket). I have enclosed my review 6 photographs, two butterfly, one of a fly, one of a drop of milk in the dye, a dive strawberry in milk, and a last of associated colors pencils. Do not hesitate, in this price range and this level of performance, Tamron 90mm this is what is does best.
