But:
On the one hand it is supposed to increasingly give photographers who recognize the benefits of fixed focal lengths not quite. This be warned: The Objektivchen has a zoom ratio of just 1! The focal length range extends from 25 to 25mm. Cut change so exclusively through relocation.
Also, the part is of course not just a miracle of light intensity - for increasing light intensity means a greater entrance pupil and therefore more volume. And even more complex correction and thus again more volume.
In addition, the objective good for the price picture performance of this play (after all, quite cheap offer) objectively looking straight into the top league. The sharpness, no matter what aperture, a skin not really socks off. The thing tends to CAs (which can be corrected well, after all, in the EBV).
And - even if the lens at the 4/3-sensor the same section shows how 50mm in KB: It has a nominal focal length of 25mm and also behaves as a low-priced 25mm lens. That means: It lists. By the time you look at the world for comparison by the described combination, and then by the combination KB / 50mm, a steeper fall the perspective clear eye. Important in portraits (long noses !!).
Nevertheless, I am satisfied with the combination, because I have been looking for something, which accompanied me on walks, and nothing makes a good figure in the studio.
The point deduction, there is * not * for imaging performance - which correspond in principle to what one would expect from such a very cheap and super compact lens - but especially for the fully verkasperten screw, with which the lens is delivered. Whoever comes a moronic idea on so, should be tarred and feathered and run out of town (although the glass thereby perhaps is still a hypothetical millimeters flatter).
