Absoluuuutely. Of course you'd notice that!
I confess – I'm absolutely a prime lens snob. That's been true since I bought my first L-Series prime; my Canon 35mmf1.4L – in early 2009. I'd owned a couple mid-range primes before that, but – once I experienced the buttery-bokeh and impressive speed of L-series...I never went back. It's a decidedly expensive obsession! I've dropped a lot of coin on deliciously fast glass. LOL!
As well, zoom lenses do not do well on the playa. The dust is so fine – like talcum powder. High quality primes are relatively dust-proof, but zooms will always end up with dust in the barrel – never to escape. Shudder.
Thanks for checkin' out this series! ;) tip!
