Thanks Kevin. Lenses without CPU's do not transmit focal length, and the camera defaults to a 1/30 target shutter speed. You would think the person that wrote the code to allow non-CPU lens registrations would have talked to the person who wrote the autoISO routine.....
I think your best option with features like this is the "OFF" position. What other than adding noise will it do? I recall how I once messed up a lot of tripod shots in low light, pushing iso to high levels, while I was wondering "wow, there is a lot of light here, I thought this exposure should be a few seconds..." I've used it initialy thinking it would save a few shots, but in the end it had more negative than positive effect on my picture taking. I now make sure it's off, all the time, any lens, and choose my iso manually as needed.
