i'm using 2 adapters. some cheap $20 off ebay, and the other is the Hawk Peng's helicoid adapter from taiwan. if i know i will be walking around and not doing any close focusing <.7m i'll use the normal adapter. Cause i always find that i'm always accidentally turning it when i take my cam out of the bag or just slinging up...
cause i zone focus majority of the time, and it's quite irritating that it's always off from the lens' distance markings
Thanks for info
