Re: Might it be possible , with an adaptor, to use EFS lenses on a 1.3 crop?

hmmm maybe but would that not take away the AF and the whole reason for the EF-S range of lenses, the whole reason that they exist is to get the rear lens element closer to the sensor which should mean less vignetting and light 'spill', if you pull it further away you get all the light focused into the centre of the sensor and this will create massive vignetting/CA in the pixels that the light does not strike straight on....

i may be wrong but buying an EF lens seems far more consistent for a FF than any EF-S lens no matter how good it performs on a crop sensor
