If you want to go further back in time, also look out for Photograms of the Year.

These will trigger studio flash, but you do need to check that they will trigger your Metz flashes.

If this 50mm f1.7 lens isn't an A series one, then that is probably the source of any exposure errors as well.

Aren't the digital camera's off today more demanding on the lens in turns off resolution?
We use the centre of the field of view of film lenses, where the corrections are best. The only downside tends to be chromatic abberation, which is more of a problem with digital.
Not every film lens suits digital capture though, to be fair.

I suspect the reduction in quality may be due to two factors - atmospheric haze and camera shake.

However film, by its nature, deals with over-exposure very gracefully. Digital does not!
was at iso-400 and F2 and hit the maximum shutter speed of 1/6000 when the sun suddenly came out - ok, that was my fault

I can't remember if the DS has two e-dials, or just the one

To take the moving subject, is it necessary to meter for every shot? The overall light in an area may be similar for quite a while and once set, manual exposure could be very satisfactory.
I'm thinking here of situations like say a race circuit. You meter, you manually focus on a spot and when the racing car arrives just before that spot you press the shutter release. No need for fast AF or auto metering, much of the time anyway.
I wonder if sometimes all the auto functions actually get in the way rather than helping.

The *istDS might be a better bet, and you can use SD cards as well.

That's not really what the rest says
There are lots of "rule of thumb" truisms that can be picked apart the deeper we get into the theory.
AS for "digital is analog and analog is digital" well of course it's true, just rather unhelpful in the real world!
