There's not a lot of detail on it yet so anyone's guess!
If it helps anyone here's the link to it:

If you follow the Flikr links the exif shows there.

Great captures by the way Alan.

I did get a Vivitar 28mm f2.8 (no idea of variant) from Dixons (c.1980s.) After about a month it fell to pieces! They replaced it with another and the same happened again. It seems it was just glued together. Shame though as it was a really sharp lens. I replaced that with a Pentax 'M' one (which I've still got) but its aperture has now got very sluggish which seems to be a common issue with that lens.

Sorry about your bad news. Why not get another second hand? Or a Q7 or Q-S1 as they have a similar sensor. The trouble with buying other brands is getting familiar with another menu system so its always that bit less intuitive.

What lenses (if any) do you already have and what do you like to take? Without knowing those its hard to make a recommendation. The normal 35mm lens line up was generally three primes; a wide angle (28/35mm), standard (50mm) and telephoto (100/135mm.) You can get zooms covering the same range but the quality of Pentax primes contemporary with the SF7 would be better. Something like the SMC Pentax-F 35-80mm F4-5.6 would be the zoom option, but if you already have a 50mm a longer or wider telephoto might be preferred.
Welcome to the PU forum by the way!

Perhaps you can buy a roll of them!
I really thought 20 years ago that a digital back would be produced for them.
Anyone tried one of these (probably not - still vapour ware): http://www.re35.net/ ? Looks like it might be just that!
So all these film SLRs can be fully digital soon (perhaps!)

Or perhaps not as it might be a remnant April fool joke. But a dedicated back must surely have been viable. I do believe such a thing does exist for Hasselblads.

Thanks John. Perhaps reduce the large gap between Just Joined and Digital? I looked at that page but didn't see the rest, i.e. Digital onwards! There's also a pretty large gap between Digital and Film, and film and General. Once one realises there's more than the first two categories it's fine, but one has to scroll into empty space to find them.
There isn't a dedicated PU queries section though.

Does eacDoes each body come with a full frame digital back?
(I'm sure such a thing could have been developed for film SLRs years ago instead of having to wait so long for the K-1.)

I noticed an 'ad' or perhaps spam from a new member selling Canon Gear earlier today, it's gone now. However, is there something, somewhere that explains the site's rules which might have forewarned said new member that selling Canon Gear here is infra dig? If I was looking for that sort of info I'd look in the FAQ but there's nothing there to say that wasn't on.
I'm sure at one time one could bring up a list of forum sections where there might be a specific sticky in a relevant section explaining the site's for sale rules but that seems to have gone too, if it was ever there. The only way I can see to show what forum sections exist is to start a new thread! This particular thread would be better placed in a site specific forum about PU issues; but there isn't one! The Forum Home link where one may expect to see a list of forum sections only has site announcements (which isn't really a member forum contributory area) and a Just Joined section. Yet there is a section on unanswered posts which might be relevant for a company to deal with customer queries to help their agents deal with new product queries but that doesn't seem to fit in here. It's as if the site's bare bones haven't been fully revamped following its new look last year.

I had been thinking on the same line as Jeff and wouldn't have bought the K-1 if it had been another APS-C camera as the K-5's and K-3's were already fantastic cameras.
