The Pentax MZ-S was launched in the 2001 at the top-of-the-range model in the Pentax MZ series of autofocus 35mm SLR cameras. But although nominally part of the MZ series is is quite different from all other MZ cameras. It was Pentax's second to last film camera with only *ist coming after in 2003. The MZ-S formed the basis of Pentax's first ever digital SLR, the full-frame 6mp MZ-D. Unfortunately the MZ-D proved to be something of a false start for Pentax in the digital world and they were never able to bring it to market.

The rest of the MZ series are divided into the double digit models (e.g. MZ-10, MZ-30 and MX-50) which are aimed at casual photographers and have the minimum of buttons and dials, the single digit model (eg MZ-5, MZ-5n and MZ-3) which are aimed at more sophisticated photographers and features old-fashioned dials for things like shutter speed and aperture. The MZ-S on the other hand features a rather innovative user interface that is unique to this camera, though it makes use some control concepts Pentax pioneered in earlier cameras such as the Z-1.

The first thing to strike you is the unique look of these camera with its sloping top plate that angles all the controls towards the photographer. This is a very thoughtful design touch, though to be honest I've ever had any problems seeing the dials on a camera with a normal flat top plate! But it certainly gives the camera a unique look.

The top plate is dominated by two large dials: to the left of the pentaprism is a nested dial for setting ISO, exposure compensation and automatic exposure bracketing, and to the right of the pentaprism is a large unmarked dial surrounding an LCD display which Pentax calls the 'select' dial. The select dial is used to control a shutter speed most of the time, but it may be used to control variety of other settings depending on the mode. One thing you won't find is any kind of mode dial due to the MZ-S's unique approach to exposure modes.

The cameras 'default' mode is a fully automatic 'programmed' mode. Just set the aperture ring on the lens to 'A' to enter this mode. You enter shutter speed priority mode simply by turning the select dial to select a shutter speed. Aperture priority mode can be entered my selecting any aperture on the lens' aperture ring. And manual mode is entered automatically whenever you move the select dial with an aperture selected on the lens. At any time and in any mode you can press the 'green' button on the front of the camera to set the camera to the shutter speed/aperture combination the camera would have selected if in fully automatic mode (even in manual mode, giving rise to what Pentax calls 'hyper-manual' mode). If it sounds complicated that's just becuase it's so unique... with a little practice it becomes very intuitive. It's like the camera really just has a single and very convenient exposure mode that gives you exactly the amount of control you required without you ever having to explicitly select an exposure mode.

As befits the MZ-S's status as a top-of-the-range camera it has an almost never ending list of features. These include automatic exposure bracketing, a multi-exposure mode, a depth of field preview, and an amazing ability to print exposure data in between the sprocket holes on the files without it intruding on the photograph.

The only thing that may be a little disappointing for certain kinds of photograph is the maximum number of frames per second for the built in motor-drive: just 2.5fps. This is somewhat behind most of this camera's contemporary competitors which can often manage 5fps.

But for me the biggest advantage of the MZ-S over other cameras over the other MZ cameras is it's ruggedness. It is an unfortunately fact that the other cameras in the MZ series are just rather flimsy. The biggest problem is the mirror mechanism which has a tendency to just stop working with not provocation at all. Indeed I bought this camera because the I just turned on my MZ-3 one day to find the mirror was stuck. And this is a very common problem in MZ cameras it seems. But, if the internet at large is to be believed this is not a problem with the MZ-S.

But overall, if you can adapt to the unique control scheme and you don't need a really fast motor-drive, the MZ-S is a highly effect camera. But one thing to note about the MZ-S is that like other cameras in the MZ series aperture is always controlled on the lens (unlike the previous Z series cameras). This means that you can’t use modern digital-era lenses without an aperture control which can be used on the older Z series cameras. I’ve actually found digital-era lenses on to be surprisingly fun and useful on my Z-1, so it is a bit of a shame that they can’t be effectively used on the MZ-S.
