Will a 35mm Minolta lens fit on a Pentax K110D digital SLR camera? Not usually. They make various adapters but you often lose some feature - auto-focus, depth of field preview, etc.
Try a pawn shop. Seriously. So many people have gone digital that they have caused a glut of cameras and lenses in some pawn shops. This has suppressed their price. No, unless you have a Minolta to Pentax adapter. what the other person said ---no
and good advise buy some used lens, anything off a Pentaz MZ series will fit the K110 - a good under rated camera
a What antoni said....
The only exception would be some older Vivitar and other 3rd party lens makers who had basic lenses for several different cameras using replacable T-4 or TX mounts. If you had any of those guys, you could look for a Pentax K mount adaptor or a Pentax threadmount adaptor.
The Pentax digitals will work with older K mount or tthreadmount lenses if you get their inexpensive K mount adaptor.
And yes, thrift shops and pawnshops are full of thread mount and K mount lenses. You'll lose some features with each, but they'll all give you an image.
Here's an article about the K mount that the Pentax takes, with brand names of other camera's whose lenses should work for you.
