After more than 100 images with the Ojektiv on a Nikon D90, I can only share the good to very good opinions. True, everything has to be done manually in the digital age and the then direct display, it is yes but no longer a problem to take good pictures with the correct settings quickly. Especially the manual experementieren that seek the particular perspectives and to the need for the money super processing and super optical performance from aperture 8 leave you wanting more. Tip: Always nice to take pictures up, especially if you are traveling in an old town. Even before manual flash should have no fear. With the wrong perspective then the brightness falls backwards quickly what can lead to great results in portrait. (It Twilight Zone & Co. greet). For this diffuser ago the manually throttled flash (with me on SB26 1/8 tel performance at f 11-16). Always ran to the object. As you can read, you can go into raptures when you feel like "different" does photography. This lens transmits at least for a really good contribution. Compatibility note, nothing for automatic fans, but you have to be a pro to have fun with the lens.
