Re: What is the difference in EF-S 18-135 IS, IS STM and IS USM?

I owned both the STM and NanoUSM versions for awhile.  Used both quite a bit.  The AF speed and accuracy is better with the NanoUSM version.  As far as IQ, they are quite close on 7D and 7DII bodies.  I think a slight edge in color/contrast to the newer NanoUSM version so I ended up selling the STM
