i prefer the 40 f2.8 stm over the 501.8. i feel it has better af and sharper than the 50. little smaller with the adapter also. stays on my m5 now 90 percent of the time.

The EF-S 24mm f/2.8 STM is the same way; sharp wide open.

The 50mm f/1.8 (any of em) need to be stopped down for best performance. With the 50mm, you at least have the option of firing it at f/1.8 with less contrast/sharpness, vs 40mm f/2.8, you don't and costs more generally.

The 40mm is less tight framing though, and delivers roughly what the 50mm f/1.8 would at f/2.8, which is what I usually fire it at so I can understand the pros of both.

Truth told, I didn't use the 50mm f/1.8 wide open except in emergencies begging the question, is the EF 40mm f/2.8 a better deal at less size? Maybe.

If you go down the rabbit hole of more cost and weight, the EF 50mm f/1.4 when stopped down to f/2, outdoes em both. But that AF motor on it, *sigh*, the copy I borrowed had the same issue as what most folks complain about. And fire it into bright light, the flare is awful, very low-contrast rendering... Hmph. At least the coating on the 50mm f/1.8 STM fixed that.

The EF 50mm f/1.4 USM needs a newer motor and coatings, badly. But, probably will never see it, this side of the mount anyhow (I suspect the RF will get one though, next year IE 2020).
