ADVISORY: I have very recently received and used my cannon 15mm f/2.8 fisheye lens hence the posts in this thread BUT NOTE if you ever get one or use one the AF/MF slider switch can actually come off the lens and drop to the floor/camera bag with no force or intention !!!! I literally a moment ago went to use mine and the AF/MF slider switch was not there, just some bare metal lens internals

. Luckily (and I mean luckily) I found it in the bottom of my camera holster and clipped it back into place

- all is now well except it could have popped off anywhere over the last two days. I will remedy the situation with superglue I guess, There is no photo of this as I was keen to re-fit the switch. It is a super delicate and very old lens but dam it is good fun !
