>>3859447>Why doesn't anyone else make a decent pancake lens?Canon makes the EF 40/2.8 and EF-S 24/2.8 and EF-M 22/2.0
Fuji makes the 27/2.8
Micro four thirds has the Panasonic 20/1.7 and a few others.
Sony makes the 16/2.8 (although whether or not that counts as "decent" is a little more debatable).
So for major players, that leaves Nikon F and the four full frame mirrorless mounts.
Pancakes are relatively niche lenses. You pay more, sacrifice quality, and sacrifice aperture just to have a smaller camera package. It made sense for a company like Pentax in the DSLR era because one of the niches they were trying to compete on was size. It made sense when Canon brought them out for EF and EF-S because they were starting to compete against mirrorless cameras and size became a big (so to speak) selling point for them (and they brought out the SL1 around the same time for the same reason). But even with a pancake, a DSLR is pretty bulky, so it makes sense that Nikon just wouldn't have thought it that important to go after that niche.
Similarly, RF, Z, and L are all new enough that pancake is going to be low on the priority list. Presumably they'll get there eventually, but they need things like teles, fast primes, wides, etc. You go after the basics before you start filling in the specialty lenses.
So the question should be "Why the fuck hasn't Sony come out with a decent pancake for full-frame E mount yet".
