First let me say the delivery was fast and arrived before the date expected.
I am only an armature photographer, and enjoy taking macro shots. I bought this lens because you can get up really close and having taken several shots with it using my Sony alpha 77. I was very impressed I took a close up of my mint plant and moved in on the smallest leaf (which was about the width of a pencil), the picture filled the screen in Lightroom 5. It was very crisp and the hairs on the leaf were very clear. this lens was a great buy and is a must for macro. the price was very reasonable, and I shall be using this lens more than any of my others, it is also good for portrait to boot
