Why there is no Canon 50mm *IS* lens?

Question

Canon's 50mm prime lenses are all non-IS (Image Stabilization) for some reason. Considering the popularity of these range primes, shouldn't Canon be interested in shipping a new, optically improved IS version?

Answer

There are two main reason why there's little chance we're going to see 50mm IS lens in the near future:

  • 50mm lenses tend to be very simple and therefore cheap. Complicating its design with an image stabilizer group would push the price significantly higher, while the added benefit of IS wouldn't be that high at 50mm focal length.

  • If you want an expensive and light-hungry 50mm, there's already the huge lump of glass that is EF 50mm f/1.2L. There's not much point in having IS in such fast (and relatively wide) lenses.
