There’s an obsession with Canon L, Sony G Master and Nikon G lenses that isn’t necessarily justified.
Before I go on, you should know that I’m not at all saying that lenses from these manufacturers are bad at all. Just go to DXOMark and take a look at their scores: Sony is very high up there and Canon is highly rated with their zoom lenses. But amongst those photographers who seriously started picking up the camera within the past four years, I’d like to relate to you a tale of how my obsession was similar to yours and perhaps even worse years ago. It started with Olympus, then went to Canon, and then I finally learned my lesson. Before you drop absurd amounts of money that you don’t really need to spend, you should probably consider how the bliss from ignorance will one day only make you realize that you’re not going to be any better of a photographer just because you own these lenses.
