A few people have noticed that glitch in the gallery software and it will be sorted when IT have the opportunity to do so.

Priorities I guess, be they shutter or otherwise....

I wouldn't be looking to independent lenses for increased reliablility, nor would I be influenced by the anecdotal tales of failures.

There are a lot of SDM lenses out there and we don't really hear of large numbers of problems. The Internet does mean that those problems that exist are certainly well documented.

The other auto SLRs such as Canon and Konica all offered shutter priority, usually a crude trap-needle system that was quite a complex solution.

The idea of aperture priority was a revelation made possible by electronic shutters and pioneered by Pentax. The beauty is that anything can be put in front of the camera - bellows, tubes, whatever - and still retain auto exposure. Really simple and efficient.

The only obstacle was the reactionary shutter priority world, but that was overcome.

We don't even need Shutter Priority. If we want a fast shutter speed, we can open up the aperture and there it is. If the shutter speed still isn't fast enough, then increase the ISO.

There are no other variables to exposure (for a given lighting situation) than aperture, shutter speed and ISO.

Photography is there to be enjoyed, so enjoy the film process!

Sadly I haven't shot any film for quite a while, and on the rare accasions that I do I find I prefer digital.

I think this one's a bit of a struggle Stefan...

Without any hard facts I wouldn't be able to comment - the trouble is much of the evidence circulating is anecdotal.

It doesn't look as though there's a mass of horror stories after all.

There are failures with every make of lens, Pentax included, but as a percentage it seems relatively low.

The SMC coating often reflects a definite shade of green.
