The Leica SL is five years old and still a wonderful camera. If I’m being honest, the brand new SL2-S is better, but not that much better. I’m keeping the original because it’s awesome and it’s worth more to me to have around than the money I could get for it. This calculus could change, of course, but it’s kind of amazing that I have an extra SL available. I don’t see the APO-Summicron-SL 35mm ever coming off the SL2-S, so it’s great that I can keep one of the M primes or the Zoom lens on the SL without having to switch lenses.
Another benefit of keeping the SL is that I can take it places I might not take the newer one. It seems silly to call the SL my “beater” camera but that’s how I’m thinking of it. If I drop or lose or have the SL2-S and Summicron stolen, I’m out a very significant amount of money. With the SL and cheaper lens it would still really hurt, but less. The SL has GPS built in and the SL2-S does not, which is handy for if and when I actually do go places again.
I no longer have a camera to use for scanning film, since I sold all my Fuji gear. I’m thinking about finding a cheap Nikkor macro and adapter and using the SL for the scanning station. Not an ideal use for such a fine camera, but should work well.
And finally, I get a little emotional about cameras. I sold the M10-P and hate myself for it, even though it was necessary at the time. I’m thinking that if I don’t have to sell the SL, why not keep it around for a while?
I have had thoughts about finding a used Leica Monochrom. If I get serious about that I’d need to sell the SL to help fund the M. In the meantime, the SL won’t go to waste.
UPDATE (February 24, 2021): I sold the SL. Could not resist trying a Q2 Monochrom.
