Same thing happened to me, I grabbed a 50/1.8 as an interim measure, but then I don't use this length much.
Canon were charging something like 40% the value of the lens, so I didn't fancy that as it could break again anytime.
The 24-105 is a great lens but the bokeh is poor compared to a prime for focal plane isolation shots.
Ideally I wild like to see the same optics with a proper ring USM.
