It's coming
We reported this a long time ago, it's good to hear about it again. There will be an inexpensive “pancake” lens coming to the Canon lineup. It will be an EF 40mm f/2.8, non L lens. How much? I'm told less than $300 USD.
For those that don't know, a pancake lens is a very thin, small and light lens. It could be fun mounted to the front of a 5D3 or a smaller Rebel.
Expect it to be announced in June with the T4i and a new EF-S 18-135 IS II.
