Is there a need for a 50mm?

Yes, that is the caveat of using that mode. If you need to go go over 1/200s (using HSS), this is no good. If you have a 5DIII or 1D X (or 6D?), the other option is to use Auto ISO and set your minimum shutter speed to 1/60 or (better yet) 1/100s. That way you don't have to deal with the 1/200s ceiling.

I can't use Auto ISO on my 6D with flash attached. All it does is turn ISO to 400. Even read the manual bit about that, it's inherent to the body. Do 1DX or 5D3 have better Auto ISO with flash? W/o flash, Auto ISO works like a charm, I use it 90% time, but flash = fixed 400 and that's it sadly

I forgot about that whole ISO 400 thing...I think all Canon bodies do that. Just taking a look at the manual, it looks like it's a tad bit more flexible, though - look at notes 1, 2, & 3 (below). I wonder how the minimum shutter speed setting affects that. I'll have to play with it when I get home.

EDIT: Two pages past that it says (of the minimum shutter speed in Auto ISO), "This function does not work with flash shooting."

so I say get rid of it and consider a good f1.4 lens, but not the Canon 50 which ids also soft until you get to f2.8.

The EF 50/1.4 may not be good on test charts wide open but it can do surprisingly well in practice. This was shot at f1.6, and it's good enough for me, unless you want sharp borders at 1.6, which is a rare requirement.

I really like the 40 STM as a 'walkabout' or landscape lens, but it can't hold a candle to the 50/1.4 for 'event' type work.

That's a lot sharper than my 50 f/1.4 ever was. I didn't find it to be of much use until f/2.

+1

I can hardly believe that's a 50 f1.4 @ 1.6... must be a great copy or something.
