>only specific focal lengths, usually 28mm and 38-40mm>slow aperture (not an issue for landscapes)>slow auto focus (not an issue for landscapes)>some are really bare bones like fixed f/9 focal length manual focus shit image qualityI think in theory they could be optically worse but I know on m43 for instance the 20mm pancake has better sharpness than most of the 17 and 25mms on the mount unless you go big and expensive. Like on the m43 mount specifically for DXOmark the 20mm pancake is the 4th sharpest lens behind 2 portrait lenses and one weird focal length kind of wide angle
