That's a really great set of portraits! Good choice of locations and framing, too - my favourites are the ones on the bench and on and under the bridge.
Thanks. I do shoot shoot a lot at 1.8 or 2 because I’m almost always balancing ambient with ocf and don’t like to tweak my lighting once I have it dialed in for a given location. I also shoot a 58g which I like at 1.8, and a 200/2, so if I dial in everything at 1.8, then I can quickly change between the 3 lenses.
