Naturally spoke initially be relatively cheaper price of purchasing this Objetives. And I've been buying the lens does not regret, especially since I was able to beat a certain extent "two birds with one stone".
Firstly, the objective is simply a wonderful macro lens. Close succeed perfect and razor sharp. What more do you want? A magnification ratio of up to 1: 1 really leaves no wish unfulfilled. Two small "downsides" are for me in truth no: Although you have close-ups fairly close approach to the subject, but I preferably plants, especially flowers Scan, does not bother me in the least. (It may be that someone who frequently photographed insects should better use a micro-lens with a longer focal length.) It is also true that the autofocus is relatively slow. But the one I take that in view of its precission gladly accept, secondly, this is at least partly due to technical reasons, and third, has the objective of a switch, with which you can choose the autofocus area (either the entire distance range or the range of 20 cm to infinity), whereby the focus can be accelerated.
On the other hand, the lens is also a practical normal lens. It is pleasantly light and compact, and if you do not always feel like it, lugging around a heavy zoom lens with it, it makes sense to also for everyday use beyond the macro range. Goethe already knew: In the limitation to only shows the master. One does not always have a zoom lens, and with its focal length of 40mm (equivalent to 60 mm in small picture or FX format) between standard lens and lightweight telephoto, it is also a practical all-round lens and a handy companion at about outings (you can also make beautiful landscapes and the beautiful flowers along the way photographed) or in family life, especially since this small and compact lens not as aggressive acts like an out at Danger on the directional to be photographed zoom lens. When I photographed analogy, I had two fixed focal length (28 mm and 50 mm) as well as a zoom 70-300 mm in use. Now when I go in, I have to admit that I determined 90% of all shots, and it was mostly the best, have done with the 50-mm standard lens. If you then consider that with regard to image quality and light intensity a fixed focal length is superior to any zoom lens, it is clear to me that this objective will continue to often and often come as a single entrained lens used.
