I just counted my RF 35s, Apparently I have 7 of these things. Some are Canon. What I WANT is the 35/1.5 because the images have a quality that I like. Of my current crop of 35s (in RF) I most use the Biogon 35/2, the Summaron 35/2.8 (truly lovely!), and my underappreciated CV 35/1.4. The others come out to play every now and then. Well, the little J-12 hasn't been out for years now -- a little sad. There's no 35/1.8 or 35/1.5 of any kind (in RF) in the cupboard.
I hate the zombies! I have limited lens funds and just can't satisfy a craving for 35/1.5 along with all the others on my wish list. In fact, my wife says I can't satisfy the craving for a 35/1.5 if nothing else was involved 😎. My wishlist of lenses (don't we all have one of those) is off topic but it doesn't (practically) include the Canon 35/1.5. I'm always on the lookout for unexpected opportunities though... it's happened before.
Now, that Canon 85/1.5 is (right or wrong) simply not on my list of desired lenses. I have lenses in that FL that make me happy, and if I were to grab another I think it would be a 75mm.
Having said that, I wouldn't mind the Nikkor 85/2. I think Brian may be partly to blame for that.
