Canon Community

I recently upgraded to a 5D mark iii camera from the rebel 4ti. I have the canon EF 50mm f1.8 II lens that I used on my rebel. From what I've read, I should be able to use it on my 5d mark iii since rs an EF lens, but the base is too small for the 5d...

I received the Rebel t4i for Christmas. It's been working great until today. The lcd screen no longer shows any information. If I press any of the setting buttons (ISO, etc), nothing shows up. It worked fine this past weekend.
