What's the best 45mm lens? (fixed rf and slrs included)

AM regularly stunned by 45/4 on my Xpan.

I was too I owned it!

After thinking for a while I ruled out slr's. When I compared my leica to nikon I realised that framelines are great benefit in composing the final image. Contax G1 viewfinder, except being always in focus is like an slr, no framelines, right? I don't like af but that planar...

The contax tessar is great for it's performance and small size. Great detail and Bokeh. Here is an awkwardly taken shot while kayaking. Long Expired film but, I like the look and this demonstrates the character of the lens shot up close. f4 I think here maybe w/o.🙂mate I have a petri 7s that I am pulling to pieces if you want the lens let me know where you are.no charge.

The Nikon 45mm GN or P are both pretty bad by today's standards. They are collectible but not great optical performers.
Tessar formula lenses just can't match up to the Planar.
I have found the Zeiss 45mm Planar-G the best lens for both sharpness and color rendition. Also, kudos must be given to the Konica Auto S2 lens. Superb color and absence of distortion. Not nearly as sharp as the Planar, though. The Auto S2 lens mount is not robust, which eventually cause some wobbling.
