The Hexanon 300/4.5 is an ideal lens for wildlife photography. It can also be used for sports, but fast action shooting is made difficult by its relatively long focus throw. It was one of the best 300mm lenses on the market in its day. It is an excellent lens that gives surprisingly sharp images with great color rendition from edge to edge even when wide open. When stopped down a couple of stops the image becomes outstanding. It is not a very large lens considering its focal length, merely 2cm longer than the 200/3.5, and it has a tripod collar. In good lighting conditions and at speeds higher than 1/500s it can be used hand held with very good results.

Excellent lens of very modest dimensions for this focal length and, for this very reason it is a bit dark. It is the only Hexanon lens to contain a fluorite element. Fluorite is a rare mineral that exhibits a low ratio of light dispersion so lenses with optical elements made of fluorite are less prone to chromatic aberration. The Hexanon 300/6.3 is extremely rare and very expensive. It is said that the lens was much appreciated at one time by the Royal Canadian Mounted Police.

The Hexanon 400/4.5 is a carry-over lens from the F-mount era. It exists in the high-gloss black version and the rubber focusing ring version. Its manual aperture operation makes it a slow lens to use. It was replaced in 1976 by the automatic Hexanon 400/5.6 UC. The Hexanon 400/4.5 is a very solidly-built lens of excellent optical performance, with good sharpness and color rendition but contrast tends to be better with the later models with rubber covered focusing ring. It has a built-in hood and tripod collar and takes drop-in filters.

The Hexanon 400/5.6 UC is Konica’s largest fully automatic lens. It replaced the much heavier Hexanon 400/4.5 which was a carry-over from the F-mount era. As an UC lens, it has a closer focusing capability than other lenses of similar focal length and advanced coatings that give it splendid color rendition and superior flare control. The Hexanon 400/5.6 UC is a very sharp and contrasty lens. It is a solidly-built lens that has a built-in tripod collar. It is a highly sought-after lens that is seldom seen today as, apparently, only about 600 were manufactured.

The Hexanon 800/8.0 is somewhat reminiscent of a Penzerfaust and was, it is said, entirely made by hand. There are supposedly only a dozen or so in existence. It is an extremely well-made manual lens that originates in the F-mount era. It has excellent contrast and sharpness for this focal range, which is surprising for a two-element optical design. The lens’ extreme length and the not entirely judicious placement of its tripod mount make it difficult to stabilize as it tends to tip forward. A heavy tripod with a solid head is a must. A specially-designed accessory tripod was offered with the initial version of this lens. I know of only one person who has one and only saw one twice.

The Hexanon 1000/8.0 mirror lens is somewhat more common than the Hexanon 800/8.0. I have seen several on auction in the last few years. The first version was produced for only a year or so and the second version was introduced in 1968. Konica’s two mirror lenses are unusual in that they are fast for mirror lenses and in that they had a means to adjust the amount of light penetrating into the lens by means of neutral density filters mounted on a dial. Most mirror lenses have a fixed aperture value. Mirror lenses are, in a way, little more than large metallic tubes that contain an imposing volume of air, In the sun, this air warms up, causing turbulence within the tube with the result that one can guess. Such lenses are thus painted white in order to reflect sunlight.

Mirror lens which used to adorn certain advertising brochures prior to 1970 and was available on special order for an undisclosed price. It would seem that Konica made two of these and it isn’t known if either found a buyer. Witnesses claim to have seen one exemplar with their own eyes at international photographic exhibitions.
