I feel like anything from 24 to 35 would be more useful.Agreed.
The Nifty Fifty is a no brainer purchase, and if there was an equivelent priced one in the range above. +1 more lens for me.
I like the mirrorless APS-H idea with the 40mm. But wow that would be an expensive sensor. Maybe they had some 1Dmk4s ones spare.
It seems like an age since Canon released any new affordable consumer lenses.
