Okay, I might get a little ridicule here for missing something obvious, but I've got kids...I'm used to it.

After much deliberation (and scrimping) I made the cash outlay for a Canon 5D body and a 24-70 mm f/2.8L lens. A good price with a $700 combined rebated made the situation just too good to pass up. It arrives, I charge the batteries, review the Lantern manual, and try to get a handle on the differences from my trusty old 1D. It's time to play!

But hmmm...the auto focus isn't working as I expected. Check the lens...yep...it's on AF. Dismount the lens, mount it again. Nothing. Check the mode...set to manual (since you can't change the AF when it's in full auto mode)...try again. Nada. Put it down, go to bed frustrated, will try again when I'm well rested.

Pick it up this morning...same thing. Pop on my Canon 28 mm f/2.8...works like a charm. Pop on the 24-70 L again, and "hey, it works!" But then I zoom the lens from 24 to 700 mm and the aperature display goes from 5.6 to 00 and the AF goes away again.

EDIT: Follow up...same thing has happened again. It appears as though the aperature reading goes haywire when it "zooms" past the 50 mm point. Has anyone else had a problem of this type with the lens contact points? It certainly appears to be a lens issue, but again perhaps I'm missing something.

I know that I'm not the only one with this combination given the popularity in this group of both the 5D and 24-70L. What (obvious, stupid, neophyte) mistake am I making? It's probably so stupid that Canon will disallow my rebates and forbid me from buying L Glass again, but I've gotta ask.

I will say this, as much as I love the old 1D, this 5D body seems to be so instinctive that it's impossible not to love it.

As always, my thanks in advance!

I have a 5D with the same lens. Never had a problem on my side. Must be a defective lens. By the way, be sure to pick up the extra battery and vertical grip holder for the bottom. The balance and extra battery life is fantastic. I also picked up the 17 - 40 f4 and use it even more than the 24-70. Wide angle on a full frame senor just plain kicks butt!

Thanks Brad, I'm thinking exactly the same thing. I think that I've got a bad contact point on the lens, but was afraid that I was missing something obvious. Everything that I've ever owned that said "Canon" was pretty straightforward and sans quirks. Looks like I'll be speaking to the good folks at Adorama tomorrow...

Grrrrr.....

Shouldn't be the case on a new lens but the contacts could be fouled with something. You can sometimes get them to work by taking a clean pencil eraser to the contacts and lightly rubbing. Good luck.

Just another 'works fine for me' thing. I'd try the contact cleaning recommendation but if not, I'd go back to where you got it and try and get another one if it's within their DOA policy.

Mr. LSC, you are the winner sir. I went over the contact points very lightly and Voila!

And just in case anyone didn't know this...DAMN! What a lens!
