It’s basically just a rubber ring for both of em on the mount. It’s the same.

Don’t get both the 25 and the 20. You have the 20, keep it. I have no need for weather sealing beyond the 12-40, which is what I backpack with, so I use the first version which is ultra cheap.

That 43 is one of my favourite lenses of all time. Tell me what you think.

I cannot focus at .95. I have a Voigtlander at f/1 and I get it right like literally 5 percent of the time. That noctilux is a killer on a rangefinder, man.

I stick mostly to 1.5 now. Haha

I tried it and flipped it. I love the 20mm 1.7 and the PL 25mm 1.4.

I found no compelling reason to use the 20mm 1.4 from Olympus when the Panasonic is smaller, and, if I want 1.4, I can use the 25 to even greater effect and it’s the same size.

I do think the rest of Olympus’s pro line is unbeatable though.

I have the 12-40 2.8 parked on my E-M1.3, but I have the 20mm 1.7 as my every day lens for my smaller micro four thirds cameras, and have for about 15 years now.

35mm Summilux FLE

Or Panasonic 20mm 1.7.
