Hello,
I just bought the Kenko extension tube DG. I am not sure if it's working properly or not. I test it on 550D with 24-105. I find it hard to auto focus with 12 and 20mm (tube). It will focus on a particular distance and not focus with other distance. I tried MF and it will only focus on a particular distance. I can't take normal pictures when the tubes is/are attached.
I tried stacking 12 and 20mm tube and it focus with particular distance. When i tried the 36mm; it can't AF/MF. I tried stacking all three but can't AF and MF.
Then i tried it with with my 10-22 lens and it can't AF/MF with any of the tubes but DG is suppose to be compatible with EF-S lenses.
Am i not using it correctly or the tubes aren't working?
