The Best Tool For The Job

The best tool for the job - is frequently a debated point. One practitioner points to one item, another holds up something different, and the argument is on. If the job is a technical one the rest of the populace stands baffled.

Suppose you are a dentist who wants to take pictures of teeth and jaws - or a skin specialist who wants to illustrate surface lesions for lectures or books. Or a mechanical engineer who wants to show tiny little parts and mechanisms. You reach for a digital camera with a good close-focus setting and try your luck.

If you have the light just right, and the white balance just right, and the auto focus on and you don't shake too much, you might succeed. Equally you might be too much in the shade, or too blue, or too wobbly.

Rethink. Get yourself a decent DSLR or mirror-less camera. C, N, P, S, or O come to mind...clap on a decent macro lens that will allow you to stand back about a foot from your subject. Put the Metz Mecablitz 15 MS-1 digital macro flash onto the lens, set the flash to take orders from the camera and go for your life.

Note: experienced clinical and macro workers do not try to use the auto-focus on the lens. They set the thing to manual and lean into the subject until they see it in focus.

The Metz people have been making flash units for decades - I have my original Mecablitz 45-CT1 from 1975 and it is still producing saleable pictures - and I've added three more of them from garage sales...Suffice it to say that Metz is the standard of the small flash industry when it comes to reliability.

The 15 MS-1digital fastens to the front of the lens with threaded rings - rather like some of the filter systems these days. There is a quick-release for the flash if you need to do something else with the camera straight away. Metz also supply a funny little clip - rather like a hair clip - that you can see in the main illustration. It is used when your DSLR has a pop-up flash.

The idea of the 15 MS-1 digital is that it can take TTL synchronising information from your DSLR in the same way that remote flashes do. The clip goes over the pop-up flash to prevent visible light flooding the subject while the IR information that instructs the flash goes out the side.

In addition, there is a standard PC socket at the side of the flash to take firing instruction from cameras that do not have a commander flash.

The two tubes mounted either side of the lens are movable - they can toe-in to illuminate subjects at very short range. There is an integral diffuser that you can rotate into position to reduce the intensity of the light.

The GN for this unit is 15 in the metric system - 49 for the imperial. More than enough for intra-oral and full-face shots. It runs on AAA batteries and will poot out 140 to 200 shots at full power.

In short, Doctor, the 15 MS-1 and the C,N,P,S, and O will be OK at TTL for IO and FF.

But that is just my initial diagnosis...
