That’s outstanding George! I need to get my 85 lubed again, it’s too dry to be enjoyable. You make me want to put in the work though.

One last one for the day from the walk this morning. Again with the 85/1.4. This one wide open and it just about melts the stem of this flower away. An equivalent f/1.1 depth of field on this camera
Cropped to 1x1 and applied BW04 profile in Lightroom. Guess I went moody because of the thunderstorms going on now.

My 85mm 1.4 was dry as well. All I had to do was remove the bayonet and focus to the closest distance. This exposed a fair amount of the helicoid in the inner rear part of the lens. To the exposed helicoid using a wood stick, I applied very small (1/2 drop equivalent) amount of grease in each of six evenly spaced locations in the periphery of the exposed helicoid. Place he bayonet back and worked the helicoid end to end. Lens became buttery smooth.
I use Dow Corning high vacuum grease - it does not outgas. Learned to use it in semiconductor vacuum chambers.
