Pentax Trio

A somewhat unintentional collection. I started with the SF7 about twenty years ago, but wasn't too happy about the lack of "creative" control. Thus the the SFX followed a year or so later. I had manual focus pentax-fit lenses with the Cosina cameras, so Pentax seemed the way to go.

Today the Pentax M.D.IMAGE system joined them. In the box is a Pentax SFXn with SMC Pentax-F 100mm f2.8 macro lens and a SMC 2x close up lens. It's complete with the AF080C ring-flash.

When I tried it out there were what I can only describe as grinding noises as it auto-focused. These noises proved to be the camera rather than the lens, which is certainly the better option.

This, below, is the first photo taken with the lens/flash combination using the Pentax *ist DS

Most autofocus cameras have the motor in the camera, don't they?

I don't know about all models of all makes, but certainly Canon have the motors in the lens, whereas Pentax is in the camera. There are plus and minus for each system. For sports photography the speed of focussing of the Canon L series is unsurpassed, which is why (in Britain at least) you see about ninety percent of sports photographers using Canon equipment.
