Hey all ! For some reason my 2 month old Canon 75-300 IS USM is starting to squeak when zooming in and out in auto focus. No squeaking in Manual focus. I'm alittle angry about this and I'm not sure what to do about it. Is there anything I can do about it besides sending it to Canon and waiting weeks or months to get it back? Also, it doesn't harm the focus quility, it just kinda drags and squeaks alittle before focusing. Thx for any info.
