KEH is the place for used gear - great selection and accurate descriptions. However I was just on their website (redone maybe a year ago) and there is a major issue in the filtering for Canon. You can filter by lens mount, and for Canon autofocus of course the choices are EF (full frame) or EF-S (crop sensor). I did EF which was fine for Canon brand lenses, but the aftermarket lenses including a lot of EF-S lenses. The problem is in their description they call it Canon EF mount for APS-C. Well hello, if it is for APS-C, then it is EF-S mount, not EF. I would have thought someone with the experience of KEH would know better. Really annoying and I filled out their online survey to inform them of the issue.
