Canon 35-350 push pull action getting sticky and tight
So is it normal for a pull zoom like my Canon 35-350 L or a Canon 100-400 L IS to be sorta rough when zooming even with the zoom tension ring set all the way to smooth? It is almost impossible for me to get a smooth range going back and forth from 35 to 350. It seems that Canon won\'t repair my Canon 35-350 L since it is an old lens and that they can only do cleaning inside the lens like front element dust and such.
I\'ve researched forums about this problem and several people have found success with a small amount of WD-40 sprayed on to a cloth and then wiped down on the barrel extended. They said it helped lubricate the lens barrel and solved the sticky zoom action and made it smooth again.
However, I\'m weary about this too since I\'ve researched at the same time that it is not safe to use WD-40 even on the lens barrel. Would this be the case even if I applied a little bit on a microfibre cloth?
Are there any other safe lubricants I can use to help solve the sticky push/pull action of my 35-350 L? Thanks in advance my fellow FM brothers and sisters.
