Yes, but it won't auto focus (of course).

Yes it will, but you will not have autofocus or any exposure mode other than stop down metered semi automatic.

F-series lenses was replace by FA-series almost 20 years ago, but only a few of the FA-series lenses are still manufactured.

Danny: "F" series lenses are no longer made, and haven't been for quite a while. They still can be found second hand tho. You can usually find F lenses on eek bay, and if you want a more reputable place, try KEH ( http://www.keh.com/ ) or Adorama's "Used Equipment/Pentax bayonet mount" ( Buy Used Cameras, Photographic and Video Equipment from Adorama Camera. )

There are still a few FA series lenses made new (the FA ltd series) but most are discontinued also. Any that you do find new are likely to be leftover stock. Both series lenses (F and FA) will work perfectly well on your K-7.

NaCl(Hope that helps)H2O

ummm... I'm not 100% sure but I'm pretty confident that the ebay link is not a genuine pentax lens. Will it work? Probably if it is indeed a Pentax K Mount lens but for the price that is it listed for I'm pretty sure you could find an actual Pentax brand lens,

I know for myself I got my 50mm Pentax M F1.4 lens for $45.
