I've had, or have, both the 43mm and 40mm and they are both excellent lenses.

On balance, the Quick Shift is such a useful feature that it tips the balance for me towards the 40mm.

If you were prepared to use something like the Interfit EXD200 kit (£300 or so) then apertures of f22 are still possible for head and shoulders and product shots.

"Only" 200 watts maybe, but in many circumstances you don't need more than that.

Studio flash kits can be less expensive than a couple of Pentax 540 flash units...and easier to use in some ways. I suppose it depends on what you have in mind to do.

True, my original comment was in error.

However, the comment about the menus on the K7 was accurate in that we were using the feature. As there was some doubt expressed about that it is possible that the feature was added in a firmware upgrade, but I don't know as I don't have a K7 as yet.

The Interfit IR trigger works fine in terms of range. The power saving function can be a nuisance, but on the other hand it does the job perfectly well at a low cost.

You probably have to subscribe and provide a membership number, but ask to be sure.

Somewhere in the menus is the option for the K7 internal flash not to contribute to the exposure when use as the trigger.

However, the alternative is to buy an Interfit (or other make) Infra Red trigger. This fits in the hotshoe of the camera and will trigger as many flash units as you like as long as they are in slave mode.

We use this routinely with studio flash and it works just as well with the Pentax flashguns.

What you do need to do is compensate the exposure for the brightness of the snow. This will fool the camera into under-exposing, so use somewhere from +1 to +2 stops extra exposure.

In theory you should need +3 stops, but on digital I have not found that to be necessary.

If what I've just done hasn't sorted the problem, then please make a report for the attention of IT.

The 40mm lens would get rather more than £10 - the assertion on various sites that they aren't rare doesn't seem to have dampened the market for them.

It would indeed - I should have made it clearer I was talking about the MV body getting £10.00 - but the 40mm has been known to exceed £100 sometimes.

It's not rare, but it is excellent and mint ones are relatively rare.

Aperture Priority is fine as you are working in stop down mode. Forget the green button and use Av. Set the aperture you want on the lens and the camera should deliver the appropriate shutter speed for the lighting conditions.

You will have to enable use of aperture ring in the Custom menu to ensure the camera shutter releases.
