Hello. I have just been given a full set of Olympus OM lenses from my dad, and a very very old SLR camera from when he was my age (19). So its all pretty old gear. I was just wondering if there are any adapters available to i can use these OM lenses with my new nikon D3000 DSLR. I know i won't get AF or anything but these OM lenses are too good to just not use. I have found the M42 adapter but i'm not sure if this is what i need. Any help would be great, thanks.
