Out of curiosity, I recently ran a test to see if my cameras could shoot well in low light -- as seen in Wolf Hall (BBC TV series, well worth watching). The results seemed pretty cool to me, so I thought I'd share:
The test isn't terribly scientific, but it is what it is. The cameras are just what I had to hand -- the C70, R5, and R5C. All are using the same lens.
Nicely done! I really need to do some candle tests one day with the 0.71x adapter and EF 50mm f/1.2L.
On the C70, perhaps CLog2 has a slight edge over CLog3? Probably too close to tell though and/or my eyes were playing tricks.
Were you using an RF 50mm f/1.2L?
