There's an old saying that the early bird gets the worm, but the second mouse gets the cheese. For the Minolta camera company, this saying is especially appropriate. Minolta's Maxxum 7000, introduced in 1985, was the world's first auto-focus SLR. That camera was also the first to use integrated computer chips in the camera's body, lenses, and accessories. The Maxxum 7000 was also the first SLR to have an automatic, motorized film advance. Yet even as their technology and cameras redefined what was cutting edge, Minolta always seemed to struggle to find market share that was equal to their technological dominance.
Despite the advancements in their lineup of "pro-sumer" level cameras and constant striving for improvements, Minolta kept an eye out for the advanced amateurs who appreciated the quality and features Minolta had to offer. In that spirit, Minolta rolled out the 400si in 1994. The 400si (also known as the Dynax 500si) took much of the best of Minolta's achievements and rolled them into an easy-to-use package. In some prior versions of Minolta's auto-focus cameras, Minolta used small, interchangeable memory cards that contained programs designed to help photographers with portrait shooting, sports photography, making landscape images, and more. With the 400si, Minolta brought all of these inside the camera so that the shooting modes became easy to select through the menu options.
Given Minolta's success at being the first to market what are now considered normal pieces of technology, you might expect them to still be at the forefront of today's camera makers - but alas - in this case, they were the first mouse to the cheese. You can (and should) find these gems today and feel the best cameras that technology had to offer in the 1990s. These cameras were an essential transition from the fully manual cameras of the 1970s to the fully automatic marvels of the 21st century.
Maxxum 500mm f8 Mirror Lens on a 450si Date Camera
Mirror lenses are interesting enough all on their own, but the Minolta AF Reflex 500mm is a special lens even within this group. In general, what makes mirror lenses so noteworthy is that they use a series of mirrors, instead of glass optics, to achieve super telephoto focal lengths, but in a form that has a vastly reduced size and weight. This Minolta 500mm weighs a mere 1 pound and 9 ounces and measures only 6 inches in length!
Of course there are trade-offs. Mirror lenses do not have aperture diaphragms, so they operate at fixed apertures, generally f/8 or f/11. That makes them a bit slower than their glass-lensed counterparts and gives them very distinct donut-shaped bokeh. Many photographers consider the unique bokeh a negative characteristic, but we have always thought it cool. We value anything that gives a unique look and there is nothing quite like the out-of-focus areas that mirror lenses achieve.
What is really unique about this lens is that it appears to be the only autofocus mirror lens ever made (Minolta actually made another for the V-mount Vectis APS cameras, but it was sort of the same lens with a different mount). Since this lens utilizes the Maxxum lens mount, which works on the later Sony Alpha DSLRs, you can shoot this lens on film or digital or both, and reap the benefits (such as in-camera image stabilization on those DSLRs).
We took this lens out with a roll of Kodak Portra 800 and walked it around for a couple of days. Having a portable 500mm lens is a fun change of pace and it allowed us to explore some familiar places in new ways.
