The Vivitar set I have has the aperture lever so you basically use them like an M lens in Manual mode. There are no electrical contacts on the tubes. So focus wide open, stop the lens down and take an exposure reading. I've found the exposures accurate, it's just a little slower than using a dedicated lens but with some practice they work well.
Maybe FotoPete's example is why I never liked my reversed results. This was back when I had an LX with a 50mm attached. Tried it for a week or 2 and decided fairly quickly to buy a 100mm f4 1:2 which was a much nicer experience. I was trying to do the same thing as David and shoot flowers and so on. Too much depth in the subject and too little DOF in the reversed lens. Plus a bugger to focus, even more so using a tripod.
A flat field subject may look ok but anything with a lot of depth just wasn't that good in my experience. I still carry the 49mm ring in the bag so in a pinch I might use it. But it hasn't been used in years. Maybe I should try it again on the DSLR.
What doesn't make too much sense to me though is why would you spend $20-25 per ring for 4-5 different lenses when the Tamron 90 or Sigma 105 versions cost around $350.00? Or you could get an older SMC M100mm f4 for less than $150.00 They will give you auto/manual everything with better results and add another mid length tele to the bag that is razor sharp.
