Sorry, should have clarified. The lens in particular that made me rethink everything else I had was a 70-200mm f/2.8L. Zooms in particular often suffer from sharpness and chromatic aberration issues compared to a prime due to the larger number of optics. This lens did not. I’m sure a comparable prime stuck next to it would still show it up, but coming from kit zoom lenses, it was quite a shocking difference.
The static aperture also helps tremendously of course, yes - nice bokeh with a tight zoom means you can easily get candid portraits that look great from anywhere in the room.
70-200 f2.8 L IS III is the Bentley of lenses, the Aston Martin, the Maybach, etc. you got the best hardware possible for the job. for the price it better be amazing! even the older ones without IS are excellent.
L glass is also a very interesting used market - those things basically don't lose value IME.
It was the IS II at the time, but yes - an absolutely spectacular piece of kit. I think it was about $100 to rent for the weekend? Very reasonable IMO, and made me realize that one could quite easily bootstrap a wedding photography business without actually owning gear.
Other than the actual business side of things, pesky details like getting clients. And the massive stress of shooting a wedding. I was happy to do it gratis for family, but I don’t think I’d want to deal with paying clients.
When I was still shooting Canon, I used a 70-200mm f/4L which I picked up for a song (C$~600 sixteen years ago?). Not the beauty of a 2.8, but having a consistent 4 made for some beautiful shots on Cape Breton.
