Hi All,
Just curious to gauge some user experiences with shooting under fluorescent lighting with the R5 (or any mirrorless camera for that matter).
My experience:
On a recent fashion shoot the modelling light on my flash head blew out and I was in a very dark room. Luckily (or so I thought) directly beside where I was shooting were two lamps with fluorescent bulbs. I turned those on and used them to increase light level to make focusing ‘easier’.
Upon reviewing the images taken with my R5 and RF 50mm f1.2L lens, I found the auto focus accuracy wasn’t as good as I was used to. Normally I achieve 95%-100% accuracy with that lens easily. In this case, with the fluorescent lights on, it was probably 10-20% lower than that, with the majority being back focused. Sometimes 5 in a row backfocused.
The fluorescent lights were the only thing that was different on this shoot and the only time the AF accuracy had been a bit of an issue.
I have read some reports that DSLR phase detect AF systems sometimes don’t get along well with household fluorescent bulbs, but wasn’t sure about mirrorless?
The sensor readout speed of the R5 is 1/60 correct? I would assume the AF calculation would be done just as fast if not slightly faster than that? Could the 60hz flicker of fluorescent bulbs be interacting with the R5 in a negative way when it comes to AF?
Has anyone else here shot under similar conditions? How were your results with the AF performance?
Thanks!
