I know its not the same but you can get some macro filters and make just about any lens macro. Thats what I did and I got some good photos with these filters. They don't work well for shooting my shrimp in the fish tank. I would like a better macro for my aquarium photography.
Here are some photo with the marco filters.
These are my shrimp. I took these photos with an old Ricoh 50mm with a x10 marco filter on it. I used a tripod too. The light was low I need to use better lighting next time.
This was taken with the same old Ricoh lens with a +1 macro filter on it. I love the detail in the eye.
The macro filters might not be the best but you can have some fun with them.
