It was purchased as a second lens for a whale 18-105, to be used on a D90, with the intention of using it for macro photography. We decided to concentrate in the full manual mode, so we bought an additional set of macro rings that did not include lenses. I have to admit, everything lived up to my wildest hopes! The background is blurred to a wadded-up uniform state, which is something I have only seen on costly macro lenses with a price that is not compatible with such a ludicrous price - 3,900 glass is new in the store, and a pair of rings costs 900 dollars. When everything is brought into sharp focus, you will be able to make out all of the pattern changes on the grasshopper's leg! On the 18th of the year 105, it does not happen or pass. And this is on the most miniature of the macro rings! Certain insects, such as bumblebees, bees, grasshoppers, beetles, and others, do not seem to care that you have to get up close and personal with them in order to get a good shot. However, you will need to focus on them at this distance. Obviously, this is the work of a novice. I didn't shoot many landscapes with it because the angle is narrow and the clarity isn't any better than the 18-105, but it still manages to portray colors in a more authentic way. In conclusion, a fantastic low-cost lens for artistic purposes; it may also be a decent portrait lens, but I haven't tried it out in that capacity.
