I've just today gotten back two rolls of NPZ 800, all shot at 1/15 f2 Canon 35... a free performance by Howard Alden (pinnacle-famous jazz guitarist) at Bumblebee's in Santa Fe..."natural" 10PM restaurant light...the two guys with big digital canons were struggling and drawing attention to themselves with their problems and their flashing, but I snuck in there with my Canon P and guesstimated exposure and came out with Christmas gift photos that will make Bumblebee Bob and Howard Alden happy, for sure. I didn't worry if the shots were perfect, I just bet on f2 and 1/15th because that was as fast as my lens would go and as slow as I wanted to hold...perfect exposures, as it turns out...I'll post when I scan...
Me, I think this lens is PERFECT for many purposes, and I plan to do a lot more with it at f2....but at f8, with a strobe/umbrella and NPC pushed a stop, I'd used it to shoot a paying portrait of a couple and their kiddo, outdoors in the evening earlier in the weekend....they were skinny and this was a vertical shot so it couldn't have been better...if they'd been chubby like me, something more in the 50-100mm range might have been more appropriate 😉
