Now sold and paid for, many thanks.

I have heard that some are. The way to find out is put them on a film camera.

A cunning plan....

Well at the moment very few people have a K7 and probably haven't had much of a chance to put it through its paces, so it may be premature to discuss comparison noise levels.

I would just wait and see for a short while and the information will become available very soon I'm sure.

You may be right Ben, in which case my FA lenses might find new found favour. Although I do rather like the Quick Shift facility on the DA lenses...

There seems to be quite a lot of noise in this thread that might need some Noise Reduction soon...

It was the large number of different sensor sizes that probably created the "need" for the 35mm-equivalent idea. It's fine when the format is a standard one - we know a 110 camera needs a 24mm standard lens and that a 6x6cm one has a 75 or 80mm lens and when those were around camera users were part of a more specialised hobby.

Now photography is so universal not everyone knows what a standard lens is, never mind a 35mm equivalent. Imagine the confusion to a beginner of a 35mm lens being described as having a 35mm-equivalent focal length of 52.5mm.....

I think the 35mm-equivalent idea is fading already and for DSLRs that's fair enough. Soon we will have more people knowing what an APS-C field of view is than a 35mm film camera view is.

The problem will eventually die out.

We know that it's the human being behind the camera that makes the photograph, not the camera.

However, technology is nice to have, and good technology especially so. There's no harm in wanting the latest, as long as we're not kidding ourselves that it will transform our photography.

Less strange than you might think - there is a definite style overlap between the F and FA lenses and this lens is not the only one.

Interesting, but I would tend to choose a system, not a different make for every purpose....

Surely you would just choose the appropriate lenses/accessories for a particular purpose?
