With a tilt-shift Ojektiv is a very special variant of photography, based on which one can play with the specific focal planes and / or in the case of architectural photography which occur with conventional lenses falling lines "of buildings are preventable. After an objective of this class is very high-priced and you will furthermore also forced to manually configure all settings due to lack of automatics, it is rather nothing for the clippers "but for very serious photographers or professionals who earn their money. Through the aperture ring makes you feel back in old times set back and it gets forced back targeted thoughts before you press the shutter button. A tripod is almost mandatory, since one the shutter speed / aperture combination usually performs without moving the lens, then adjust the offset. By vertically Tilting sharpness over the entire range can be extended, for example, at a slanted object. When shifting to avoid the said converging lines. Once called a lens with these features its own, you will certainly make to get to know the way to take photographs with all possible settings. Thus, getting to know "absolute duty until you can routinely handle it. Now to the product itself: The packaging looks a little cheap - after all, should be in a 1000, - are objective. On the other hand, lets you look at them not distract anyway long, you want the product ... The lens itself acts already very robust at first glance. Unfortunately, a sun visor is missing, this is a bag with it, wherein the lens undergoes a degree of protection when it is not used in the camera bag. I did not test the lens on a full frame camera, unfortunately, and thus has to deal with the crop factor. When my camera is still working perfectly 20D Canon, who accompanied me faithfully for many years. Through the crop factor is from the 24er-wide in about a still sufficient 36er-Wide, which narrows the angle a bit, but is still effective enough for me. Initial tests without any shifting or Tilting out of hand already showed the very high quality of this lens and I would imagine that it therefore often use as normal with me "justified Wide. The light intensity is pleasant enough and already as a normal" lens underlying focus is reflected without any blemish. In the field of landscape photography, it seems to play off its strength in the middle aperture range. Distortion I consider acceptable - if alternative lenses easily cost twice particular. The little screw "for the shift functions are initially some getting used to - especially when both are at the same level you move the beginning I was often a little hectic." And thus slips a the level manchesmal equal to the largest setting level. Here you learn very quickly that also extends a subtle turning the little screw - and: the one as in the past should take some time for the photo itself again. As I said, a tripod is very helpful here, because you've lost out of hand using shifts almost. A manual focusing is compulsory and thus learns new know his camera again, because it often has been mode M "rather neglected. The Sharpness setting on the lens is smooth and leaves absolutely no negative point. Likewise, the aperture setting, as these locked discreet and you thus experiencing no surprises here, but what vorkahm when adjusting to the camera from time to time. You can choice the panel thus put all his attention on the focus and in the process to the desired displacement of the objective level. All in all I think the lens in its price, performance ratio than absolute tip. In particular, the ambitious photographer could thus, without having to spend the same money twice to turn a further variety of his hobbies. By brilliant in my eyes Ablichtungsqualität it will probably be my new main objective in landscape photography - fortunately also take him to the fact that significantly increase the varieties. Absolute recommendation!
