Hi,

Visiting Finland in December and expecting low light outdoors all the time, how much difference would there be in practice between a 1.7 and 1.4 lens?

I think this is half a stop which means that the shutter speed could be 50% faster at the same iso for the same exposure, is that right?

I'm working out whether I can justify the olympus 20 1.4 at the moment and am not sure how much difference it would make over a 1.7 lens (not taking into account whether sealing or anything else),

Cheers

Not much.

Low light outdoors with snow everywhere is not that dark, especially close to city lights. F1.8 should be enough.

Well that depends entirely in what part of Finland OP is travelling. I can easily see december Helsinki being filled with wet slush and dark grey mist everywhere.

In lapland though, it should be decent but daylight is limited. In Kittilä(popular place called Levi is there) there is only 5 hours of daylight at all currently.
