I've got this canon 75-300mm f/4-5.6 but the AF motor is broken. If you set it to AF and manually turn the focus ring, you can sort of feel a change in resistance when it thinks it is in focus, but generally you are on your own. Doesn't seem the sharpest of lenses even in MF. Postage will be about a fiver I would have thought but I'm only asking for whatever that costs.. was gonna take it to bits to have a look, but if anyone wants to actually use it let me know BY PM please
