Canon Speedlite ML-3 battery but you'll need a computerThe Canon Speedlite ML 3 is a TTL ringlight for Canon EOS film cameras (though you can use it on any camera with a hot shoe in manual mode.) Not much in the way of control here, but if you're looking for a simple ringlight, this could do the trick. The strobe ring clips onto the front of the EF Compact Macro 50mm f3. 5 or 100mm f2. 8 Macro lenses (not the L one, the first one.) In excellent condition.
