lol, i know i know! To be honest, I only discovered this forum when thinking to put the FA31 for sale, i normally lurk over on pentaxforums, but now that I'm living here in the UK i think i'll spend more time here.

If it makes you feel any better, I still have my FA77 (which incidentally took the pictures of the FA31) and would never sell that lens. And I have a FA43 on the way . Though the FA31 is an excellent lens, I'm not super keen on the focal length or it's size/weight. I'm always wishing something slightly wider, or something slightly longer was on, and as a walk around i'm always wishing it were smaller. And on the occasions that I really do want a normal-ish lens, i think the DA35 macro ltd would serve me better (hopefully will pick one of those up too). I think if i shot film I wouldn't be letting it go, but i'm all digital, and with the 645D out now i don't see Pentax ever bothering with full frame cameras.

Selling my 31mm limited to fund some other gear purchases. I've had this lens for about 7 months now, however it is not a UK purchase. I'm an american expat, and purchased this when I was back home last April from B&H. Will be happy to pass along the receipt with purchase if you want. Surface wear due to use, but the lens is optically in great condition. Also being sold with it is a Hoya Ultraviolet UV(0) Super Multi-Coated (S-HMC) Filter which has been on the lens since day 1 (worth about £20 on it's own).

Asking £650 shipped in the UK (plus pay pal fees if paying with card). Will knock £10 off if you happen to be in West Yorkshire and want to pay and pick up in person ... although you might need to wait till the snow melts a bit to get anywhere!

Feel free to PM me with any questions you might have.

EDIT: Oh, and if you have a Tammy 17-50 f/2.8 and/or a AF360FGZ flash I'd be up for some partial trading action.
