Anyone familiar with the "Gold Trim" Objetive is insane, because here, in contrast to the position 24-70 the zoom ring has been reversed with the focus ring, the 28-300. I reach constantly in the focus when I want to change the focal length. Is time the sun visor in terms of transport and put it upside down to fast times in this position (ie upside down with an attached sun visor) are photographed, you break up half the finger to reach the zoom ring. The sun visor itself does not lock properly on or dissolve on their own.
Thus, it is obtained Allerd a 10x zoom with excellent sharpness, very good PR and a 77 filter thread, which has established itself as a quasi Standdard. Buy recommendation for photographers who must respond with a single body quickly to changing Sitationen.
