The Problem With Canon Zoom Lenses
If you're looking to buy a Canon zoom lens watch this video. There is an issue with Canon zoom lenses like the RF 24-105mm, the RF 28-70mm, RF 24-70mm and RF 70-200mm. If you're thinking of buying these Canon zoom lenses to improve your photography you have to know that the barrel of these lens extends as you zoom and that action sucks air and dust into the lens chamber. All that dust doesn't always come out leading to dust getting trapped in your lens. Canon really needs to work on fixing the flaw in their lens design. To avoid this I would suggest shooting with prim lenses.
