You didn't specify which 500mm f/8 lens, so I'm assuming it's one of those without the electronics to communicate with the camera. If that is so, then the camera will report that there is no lens attached. You have to switch the camera to the Manual exposure mode and set the exposure yourself.
The step-up ring will on any lens with a 49mm filter thread, regardless of the manufacturer. The easiest way to find out whether it works with any given lens is to see whether the ring fits onto the front of the lens (you could also read the filter size written on the lens itself). If it doesn't fit, purchase the appropriate step-up ring. That will be much cheaper than buying a whole new set of filters. If the new lens(es) have a 55mm filter thread then you don't need the step-up ring at all. The filters will mount directly onto the lens.
Is the lens switched to manual as well as the mode dial. If the compatable lens is a minolta requiring an M42 adapter make sure that the protruding arm/rod is operating the shutter when depressed and that the adapter when fitted operates the lens when turned from auto to manual. Good luck.
Try turning the camera off, take the battery out, reinsert it. If that doesn't work, the manual says to contact your local Sony dealer. You might also want to try taking the lens off, making sure nothing is hindering its communication to the camera body. Try using another lens if you have one.
You can try going to the camera store, and finding an adapter ring for it I've got an alpha 100 and can use konica/maxxuum lenses, and with an adapter I can also use Pentax screw mount.I wouldn't have bought the sony a100 unless it would take my other lenses too. Take the old lens and the a300 in to try out for a good fit.
Simple answer...Take your best working lens to a camera store,and ask to test a sony a100 digital camera. ALL Minolta Maxuum auto focus lenses work with the a100. This includes Konica/minolta type also. If you don't have an auto focus lens, it still might work-but you would loose some features, by swaping camera bodies. In the least it would cost you nothing to find out what camera they would work on, and save you enough money to partly pay for the new camera body you want anyway. Shoot a few stills with your lens on the different bodies-after all your not waisting film-until you find one that is good for you. The camera shop might even have an adapter ring for your lens to the camera body of your choice.
