As Close to Giving it Away as I’ve Seen: 52% Off the Zeiss ZE 25m f/2 Distagon
See my Zeiss DSLR lenses wishlist.
At 52% off for the Zeiss ZE 25mm f/Distagon (for Canon EF), it’s crazy discount.
Personally I prefer the Zeiss 28mm f/2 Distagon as an all-arounder, but 25mm is good also.
Putting a DSLR prime lens on Nikon Z7/Z6 or the Canon EOS makes good sense—these smaller classic Zeiss lenses balance nicely.
The Zeiss ZE 25mm f/Distagon is a prime lens of a reasonable size and weight for the Canon EOS R using the Canon Mount Adapter EF-EOS R, below.
