Thanks for sharing Mr Surapon.Happy New Year.
Love that site as well. Another useful one from Canon Europe:http://cpn.canon-europe.com/content/education/infobank.doI particularly like the section on batteries. I've had two half-charged LP-E6s in the fridge for the last nine months in plastic bags with silica gel. Took them out yesterday and both showed a charge in the 40 percentile range. Once they warmed up (took about ten minutes), they were ready to shoot.
I might suggest surapon, that there are a fair number of us out here, myself included, that are blissfully ignorant of what is available in that Learning Center. We need someone like yourself to help us focus our minds...thanks for that!
The article on extenders is interesting and since the Canon ones aren't compatible with anything except "L" lenses of a certain range, think I'll check out the Kenko ones that can be used with any Canon lens And Kenko is cheaper too!
Thanks for the links Surapon.I noticed that there's a fairly blatant error in the first article regarding Canon's extenders. There's a reference to the "EF 135mm f/2.0 L IS USM lens". "IS", I thought to myself. I don't remember my 135 having IS.
