My Darling Wife came over to see what I was working on. I was putting the finishing touches on my lens project, and she asked what is the difference. I gave her a quick demonstration/lecture on the differences between fast primes and slow(ish) zoom lenses. She was immediately impressed by the superiority of the fast prime lens as old as I am, bodged on the wrong mount and manually focused with stop-down metering. As she should be. I use a fast prime at work, too, and compared to that lens the wide-range general purpose zoom one of the other guys uses looks optically broken.
If you don’t have a fast prime lens, don’t rent or try one. You will end up with fewer dollars.
