So I guss I'll try and find a 2x converter with a contacts if I can, and if not I'll get one without. Its not like my reversing ring lets me use the in camera metering anyways lol
Hin writes about Kenko's 2x macro converter:

The same was sold under Vivitar label. The Panagor with similar name is not as good optically and do not focus on infinity. The 50 you have is one of the best choices you have to put on the macro converter. I've used that combo quite a lot before I got my first dedicated macro lens, and still it ends up in the bag if I don't have space for the macro lens but already decided on a fast 50. I've used it also on longer lenses, though you don't get 1:1 macro you get good reach for butterflies etc.
Reverse rings are fun. But do you mean filter-thread-to-filter-thread or K-mount-to-filter-thread. For the former your fast 50 would work well in front of a longer lens. This is like a real high quality front lens converter with SMC and all, and all auto exposure functions still works (if the long lens have KA contacts). A 50mm lens in front of a 100mm lens gives macro 2:1. A 28mm lens in front of a 135mm gives you roughly macro 5:1. You will want to do this so that the reversed lens has an apperture ring, since you will want to keep it wide open to let the light in, and then close down with the second lens.
This is what it may look like.
The later option really don't work well until you put the reversed lens in front of bellows or extension tubes. These can be completely manual (and cheap) since you will anyway not have any automatic controle over the lens when it is reversed.
