Once attached to the E520 not go unnoticed: Is very tired in his hand. Opposite the Kitlinsen course to saddle a lot of weight, but the feel and value, as well as the benefits that one gets when working with the objective perspective, the extra weight immediately.
The lens has a brightness range of f2.8 (12mm) to f4.0 (60mm).
The full aperture performance is very good, indemnify succeeds effortlessly with a good bokeh. Even at full aperture the lens features sharp right into the corners.
Wavy distortion in the range 12-14mm are visible, but can be corrected easily and quickly through programs such as Olympus Studio 2 and PTLens.
Color and contrast are very good, chromatic aberrations not an issue.
As a portrait lens well suited to use as a wide-angle lens and super reportage.
Autofocus is incredibly fast, unerringly and even in low light you meet with this lens autofocus still where 90% of the other lenses must give up. Even more light-lenses as the Sigma 1.4 / 30 or the Olympus 2/50 at a disadvantage here.
Thanks SWD technology can intervene manually at any time, should be desired or necessary corrections.
The 12-60mm SWD is sealed and so does not have to fear most adverse conditions.
I have had my lens from +30 degrees to -20 degrees in use, at -20 degree of zoom is a little sluggish, but the AF remains unerringly and errors occurred under any conditions.
The only downside of the lens on the Olympus E520 is that you can no longer use the internal flash when the lens is attached. By the dimensions of the lens you get circular shadows on the image (below) because the flash just not "over it" comes. Since I have an external flash (FL-50R) does not irritate me but.
Conclusion: Quite cheap, it's not just, no flyweight, but it's worth every penny and the weight into perspective by the feel immediately.
I can pronounce the lens fully 5 star and an absolute buy recommendation!
