I know I will, but at least I can come here for therapy.

I asked the question in a topic a while ago, do I sell,or keep. I've taken the advice of the masses. Well, 19 to 2 in favour of selling anyway. Of course, it could have been pwynnej logging in using several aliases.

The term auto focus is not quite correct when applied to flashes. Auto zoom is I think what you mean, where the flash head moves in and out depending on whatever focal length the lens is set to.

By far the best Penatax flashes for your camera are the AF360FGZ and AF540FGZ. The 360 lacks the swivel head of the 540, both tilt for bounce flash however. Other makes exist also, like Sigma and Metz, with varying amounts of compatibility with the Pentax flash system.

I thought inflicting pain on oneself was called masochism.

SOLD, thanks to all for looking.

£230 incl. postage (next day Special delivery) to a UK address, final answer.

I think it's reasonably safe to say that ALL Pentax flashes are safe to use on ALL Pentax SLR's, film and digital.

Some functionality is lost with certain combinations however, and there are too many possible combinations to list them all here. Not that I've tried them all, but quite a few.

Without some kind of meter, be it in-camera or handheld, I find it almost impossible to guess exposure settings because there are actually three variables affecting exposure. Shutter speed, aperture, and ISO. My little brain can't cope with all that.

Shutter speed will normally be determined by your subject, fast moving or static, and all points in between.

Aperture choice is influenced by how much depth of field you want to show.

ISO setting compensates for the available light and being able to get a correct exposure from the other two.

So my advice is, get a good hand held light meter, preferably one that measures flash as well. Use that to work out what settings may be required for your scene/subject, then transfer the settings it gives you to the camera.

Job done.

There is a very good book called "Understanding Exposure" by Brian Peterson. I recommend you acquire a copy.

In that case, I can probably tempt you with a superb condition, as new, SMCP-FA 100mm 1:2.8 Macro with original caps then? Same price.

And I was in Cornwall last weekend, I could have bought it with me if I'd known.

£250 anybody?

An offer in the (very close) region of £250 + postage would make it yours.

An offer in the region of £250 would make it yours (or anybody else's for that matter) and might keep your LBA in remission for a bit longer.
