The tilt function gives me excellent opportunities to control the sharpness of the course.
Distortions or so-called. Miniature effects hereby are available to me. The lens is top handles. Focusing is done by a very wide rotating ring. This has absolutely no play on and can be controlled with just one finger. The lens needs time and leisure for conscious photography, a tripod and at best, a L-shaped bracket. It delivers stunning results, however, depends on a photographic training with large format cameras or at least require a intensive study of the lens. Having the lens no autofocus, probably explains by itself, however, should not go unnoticed. The optical performance is optimal to my D3 and D3s. Since I magnify any images on 6x9 meters :-) and I therefore have no D800 in action, I can not judge the statements of the previous speakers with regard to the sharpness. Thank you to read this review for your time.
