Hi guys/gals

Back in December 2017 I made a trip to Canon Service Center in Costa Mesa for a sensor cleaning and while I was there out of curiosity I asked when will Canon stop servicing their first generation IS super telephotos I was informed that starting January 2018 first generation IS super telephotos will no longer be serviceed by Canon. If you own any of these lenses EF 300 f2/8L IS, EF 400 f/2.8L IS, EF 500 f/4L IS and EF 600 f/4L IS Canon still cleans, checks, and calibrates but won’t have parts to replace.
