So i dropped my 50 1.4 on the floor.

It kinda broke.
Two pieces of glass fell out. 1 of those internal glass and 1 of the outer glasses that can be screwed back in.

So i tried putting it back together and it still works. But i think i put the internal glass the wrong way because the shots are kinda blurry. I tried to disasssemble the outer glass again but it feels like it's ment to go one way (in).

Have anyone had any experience with this? I dont think its completely broken, i just think the pieces fell out undamaged.

Try dropping it again maybe?

Hmmm

There are some af fix tutorials out there that show that lens being disassembled. Search for them and you may find a picture that shows the elements in their correct positions.

Does it still try to autofocus? The focus system on the 1.4 is extremely vulnerable to damage from impacts.

Last year I dropped my 50 / 1.4; nothing came apart, but the AF became unreliable. Sent it to Canon repairs and they fixed it without question; I think the whole process only took about seven days and didn't cost me anything other than the shipping.

cool, Canon USA?

Had exactly the same situation as the OP,with the same results (blurry @ f/5,6 and bigger).
Sent the lens to a certified Canon service and they did a great job:completely realigned the optics and "did something" to the AF wich is much smoother and precise since the surgery.
Bottom line:my 50 is way better in every aspect now.

Damn near made me spill my beer.

OP: Sorry to hear about your lens. Hope you can get it fixed up.
