From 85 to 90 I had a lux and Nikon 35 /1.4 as normal lenses. The Nikon was a normal lens the lux flared and misbehaved I always used a hood on both and both were like new from box.
But you only use fast cause you might need to use fast.
Today I use a /2.5 cause Im in a coffee shop 2 hours before sunset, eating muffins.
