For most of the past year I have been using an Olympus E-M1X, on a tripod, at base ISO making images at night of my home town mostly with a 35mm prime lens, my preferred option. The results are OK-ish but the Oly sensor does struggle with noise and shadows in almost any circs so far as I can tell.
I am thinking of trading up but the question is whether to look at a Z6 or R6 level over an R5 or Z7. Will the lower resolution sensors make a difference in low light or is something like the Z7 going to be fine bearing in mind that for this particular project I am mainly using a tripod with exposures of up to about 60 seconds (the max on the Olympus before bulb mode, I think). I do go handheld occasionally but usually only when bright city lights are involved and ISO 800 is about as far as I can take it on the Oly before IQ starts to suffer. I have no need to freeze movement as no people are in the images.
The intended output is a book of around 8” x 10” in portrait format so I will need more than ‘roughly OK’ if posted online or printed real small. I need perfectly fine at 300 dpi full page or more. That is partly why I am looking around.
Anyone with experience with cameras like these after dark?
