I purchased it as the main one for the D5000 bodysuit and at first it simply suited me as a given. it was possible to really appreciate its merits only after buying a 35 / 1,8 fix, which, compared to 18-105, turned out to be not a lens, but some kind of accessory (which was very upsetting, since it has a nominal maximum aperture of 1,8, itโs really possible to shoot only possible with 2.5). screwed on the protective UV filter, attached the cover with a fishing line (it takes about 15 minutes without any holes and damage: carefully, one by one, slightly pull back 2 thin "clamps" at the back and remove one of the spring keys of the cover, put a small loop on the pin inside the groove from the key and we put it in place. on the second ring we make a loop on the throat of the lens so that it does not get off it, but it is not tightened either, otherwise you wonโt put it on when changing lenses. thatโs it, it wonโt be lost.). I RECOMMEND! for enthusiastic lovers, the lens is wonderful! Z. Y. instead of a fishing line, it turned out to be more optimal to adapt a thin elastic band.
