>>4394466>Sell 50mm if you'd rather have a pancake and can deal with 1 1/3rd less stops of aperture>Sell 40mm if you'd rather the +1 1/3rd stop of aperture and dont care about pancake form factorThen take that $80 and buy a nice dinner for yourself, because nothing else worth buying is going to be as cheap.
However,
>EF 28mm f/1.8 is a decent pick for wide-angle>EF 180mm f/3.5 is a macro king if that's why you have the EF 100mm Macro, and can be fucked lugging it around.>EF 70-200 f/4 is probably worth if you'd rather have a zoom lens>EF 100-400mm if you want muh reechI'm all for prime lenses though, so my bias tells me the 28mm (or a 24mm), the 50mm and 100mm you have already all together make a well-rounded and powerful kit.
