Wide variety of photographic equipment can be found on line - unfortunately, most will suffer from common or age-related problems. As a user or collector, you should be certain that the item you are buying is in good working condition. I will not hide behind such statements as "Was OK when put away three years ago" and "Not sure if it works, but the shutter clicks and all the dials turn". Please read the whole text carefully and rest assured that this item was thoroughly checked and is accurately described. Zenza Bronica Zenzanon 250mm f/5.6 is a manual-focus prime telephoto lens designed for the Bronica ETR series (ETR, ETRS, and ETRSi) 6x4.5cm medium-format film camera system. The 250mm focal length on a 6cm x 4.5cm negative is roughly equivalent to a 145mm focal length lens on a 35mm negative. The lens delivers a narrow field of view well-suited to isolating subjects at a distance, ideal for portrait work, nature, and detail-focused shooting on medium format. Optical construction consists of 6 elements in 6 groups, the lens is praised for its sharpness, good contrast, and excellent build quality. Cosmetically in wonderful condition, with practically no signs of use. Focusing action is smooth and fluid; there is no oil on the aperture blades, no haze or scratches on the optics. Automatic aperture mechanism operates correctly; diaphragm blades are clean and snappy. Focusing mount has no dents or dings; filter mount has no dents and accepts filters effortlessly. PLEASE NOTE: I do not own an ETR series body anymore, thus cannot check the shutter function. Bring your own Bronica body to check full functionality - judging by the cosmetic condition of the lens, I am sure all is well. Includes front and rear lens caps.
