Low light on the streets of Toronto (those are dark streets) on bw film @3200 is 1/8 for f2.5/2.8. Even Yonge, King, Queen in DT are dark streets.
Color Skopar is way too overpriced now due to its rarity. You could get Canon 28 3.5 or 2.8 for less to have good results. Those lenses served GW for years.
ZM 28 2.8 ain't in the low price range as well. I mean, price/results ratio might be not so good under low light.
VM 28/2 seems to be priced more well adequate and it is closer to low light, but still no cigar, IMO.
Here is TTartisans 28 1.4. This is low light lens and results I have seen on BW films are impressive. And so its cost. Just not sure if its diameter will not block RF, framelines windows on CLE. It should be relatively easy to check without lens, but with CLE in possession.
To be honest, I would just get used Nokton 40 1.4 for low light and Orion-15 for close street work. Might be in the same price for both at single lens price from OP list.
Compact duo to match CLE.
And during Covid you are better with 40mm range for now. 28 will bring you too close, if you want decent street picture, not architectural shot, which Toronto downtown lost its charm for... Canada is about to be one of the last counties to get vaccines for regular citizens, BTW. It looks like we would have to keep distance for another year or so in Toronto.
28mm with Orion-15. At Union.
Three meters, maybe more and obviously I wasn't close enough.
I don't think it is cool to get too close to people at this moment. Many are wearing masks on the streets in Toronto DT. And you never know why...
