Another question

On my Mesuper and MZ7 I used a skylight filter as protection for the lens. Is this still a good idea in the digital world?

There's no more or less of a reason to use a filter purely as protection for digital. Some people still like the idea, some don't. I've stopped regularly using filters as it means there are fewer surfaces to keep clean.

Digital is affected less by UV light than film. There's hardly ever any advantage in using one on digital in terms of image quality.

Skylight filters have a slight warm-up effect. This may spoil colours sometimes. You can always increase the colour temperature of the image with post processing when you want the warm-up effect.

UV is the best in general, but you can buy plain lens protection glass,
sky light will do but it does alter the light very slightly.

There are lots of old threads on this one. Do a search for "knee"...

Edit: This is the thread.

I have had a couple of occasions where the camera with lens has either hit something, or been dropped (strap breaking), and the filter on the lens has taken the impact. They were cheaper to replace than the lens itself! Also I'd prefer to clean 'muck' from a filter by wiping it clean rather than the lens front element.

For digital, as UV is not such a problem (so I've been told), you can get plain 'lens protectors' - I have got a couple of marumi dhg protectors which give very low reflections, and are thin as well.

I doubt it was a pentax strap that broke. All of my Pentax straps have been bullet proof.

No - it wasn't a Pentax strap - lesson learnt.
