The ring threads onto the front of any lens with a 49mm filter thread, just like a filter. The front of the lens then fits onto a camera body, effectively mounting the lens "backwards" or reversed. With most lenses, this allows the lens to focus very close, for close-up or "macro" photography.
There are adapters available to fit the old Minolta manual-focus lenses on Sony alpha-series dSLRs as well as Sony NEX-series interchangeable lens cameras. The lenses obviously will not autofocus and, depending on the lens and camera body, you may lose some or all exposure metering capability.
To my knowledge there are no digital SLRs that take the old Pentax screw mount directly. However, there is an adapter available for the Pentax K series (not very surprising). In addition, there are adapters available for the Sony NEX series and the Micro Four-Thirds cameras from Olympus and Panasonic.
You should have no problem, if they are maxuum af. The others should work too- I have an Alpha 100. The alpha 100 works great. I used to run my own photography business, and searched around for quite a while before I found the alpha. There is an adapter ring that i bought, that makes it possible for me to use my favorite old pentax screw mount 135mm f1.6, or any other screw mount, on my alpha 100.
The only drawback I found was you cannot use any other flash(at this time) than the onboard one-or the sony only flashes-which are a little pricey. Different size hot shoe is the reason. I haven't found an adapter yet-but I'm sure someone will make one. The alpha doen't have a real time display- or asa of 3200. I'm hopeing for a firmware update/upgrade to correct this. BUT the newer models with a higher than a100 number do have realtime lcd, and do go to asa3200. And they use either sony mem.stick or CF cards happy shooting
