...and the Flickr version looks better than the one you posted in the gallery, brighter and crisper. Nice shot, I like it.

You're linking to a web page, rather than the actual image. If you right click on the image itself, you can then copy the URL from there, and paste it between the IMG tags.
I would do it for you, but I don't want to ruin the sense of achievement you'll get when you do it yourself!

That was me. I think I could have got a little more for it on ebay, but I was happy to pass it on to a deserving P.U. I think I gave someone on here (I forget who) £60 for my PKA mount, and consider that I paid about the going rate.

The Pentax 1.7x AF converter is in a similar position price-wise (at least it was when I sold mine), in that they're around £200 now, but only £70 two or three years ago.
Luckily I bought both the AD2 mount and the converter at the right times.

The zimbio test chart has too much "crap" on it. You can't know where the sensor is focusing if it is not lined up properly with the viewfinder indicator, so you can't adjust the focus properly. If you are so inclined, you could look at "Yvon Bourque blog" for very well made charts for focus adjustments. His charts are also endorsed by Ned Bunnell (president of Pentax USA).
Strange, that Zimbio test chart says "Copyright 2008 Yvon Bourque"... The zimbio test chart has too much "crap" on it.

When 'digital' lenses were first introduced, one of the benefits was that there were better coatings on the rear element, which would reduce/eliminate ghosting produced by reflections from the sensor.
With film, the surface of the 'sensor' is matt, so non-reflective. A digital sensor has a shiny piece of glass over it which could bounce back some of the light that was projected onto it. This reflected light could then bounce back off the rear element of the lens and produce a ghosted image on the sensor.
I have used various non-digital lenses without seeing any evidence of this, but perhaps your lens has just the right curvature on the rear element to focus the reflection into an image, the blue-ish dot. :
Could be the reason, may well not be! Does the rear element have a concave curve to it?

There is a rumour mentioned in this weeks Amateur Photographer magazine that Jessops are looking to hook up exclusively with one large manufacturer although Jessops deny this.
The article mentioned Jessops has strong links with Canon though, rather than Sony.

I think they'd have to be completely bonkers to drop Nikon at the moment - perhaps though they're looking to completely self-destruct.There is a rumour mentioned in this weeks Amateur Photographer magazine that Jessops are looking to hook up exclusively with one large manufacturer although Jessops deny this.

Can't remember who that was, but someone really, really likes theirs. I'm sure they compared it favourably with a Limited lens in one thread... Who was that? : I have heard good things about the Pentax SMC-FA 24-90mm.

Sounds like a fairly lucky escape for you.
