“QUESTAR IN KENYA On Safari With The 700”, the complete six (6) page full color illustrated brochure featuring a series of color photographs of wildlife taken by Eugene J. Cohen, M.D.. during one of his annual visits to Kenya.
The photographs in this brochure were taken with his Questar 700, the first production version of the patented 700mm f/8 catadioptric telephoto lens that were introduced in 1976. This demonstrates the kinds of results that one could expect to attain when safely photographing wildlife from some distance with the compact and relatively lightweight (about 4 lb.) Questar 700 lens using a camera with the then recently released (1977) Kodak EKTACHROME 200 Daylight consumer slide film. Wildlife shown in the brochure include: Lions, Cheetah, Eland, Gazelles, Giraffes, Zebra, Hippopotamus, Wildebeest, Impala, Dik-Dik (captured in mid leap), a Rock Hyrax, and others. Also shown are several birds including a Gray Crown Crane, Augur Buzzard, Crowned lapwing (Crowned plover), and more. Some of the animals were photographed in repose, while some were captured while in motion showing how sharp the image could be even when photographing at f/8.

Keep in mind that in the late 1970’s and through to the digital age, these were very good photos. As famous and well-regarded as the EKTACHROME film was, many of the most memorable NASA images were taken with this film, we at Company Seven wonder at what results could be obtained today using the Questar 700 lens with a state of the art digital SLR camera with images processed with modern software.
