>>3077390It is rather rare now-a-days. It is mainly just cheap kit lenses.
Even terrible lenses are okay when stepped down.
The most notable bad (as in DON'T BUY EVER) lenses released over the last few years have been mirrorless.
Sony has two. The 16mm (soft as fuck) and the FE 50mm (turtle slow autofocus). Their APS-C kit is also looked down upon, but it is at least sharp and compact as hell. Without a lens profile applied it will make you puke though. Sony also has a habit of making their mirrorless lenses absolutely huge.
Fuji also has some bad lenses. Their 18mm has slow as fuck AF (the slowest lens I have ever used, you'd be better off doing manual focus without focus assist) and terrible sharpness. Their 35mm f 1.4 also has sharpness issues until stepped down (might as well buy the superior 35mm f2), and super slow AF(which has been improved through a firmware update but still not ideal). A lot of Fuji's 'fast' lenses are also pretty much unusable wide open.
