I seem to have difficulty getting a focused picture when there are two
or more people in a shot. Two people I might get lucky once in a
while. Three or more, I have no chance. What happens is, the camera
focuses on a particular spot and the rest is somewhat blurry. I have
tried a few settings and gone to automatic at times-and I still miss.
Can someone shed some light and point me to a particular setting Or something I am missing. I am sure Depth of field has a role in this.

My equipment is the 5d Mark iii, 85mm 1.2, 24-70 2.8, 50mm 1.2 and a
70-200mm 2.8. They are all Canon lenses.
I know each lens would pose a different set of settings but if you
could pick one, I'd appreciate it.

My last outing was last night-my nieces sweet sixteen. It was a dark
club but I used the 600ex-rt flash.

please break down the steps and terminology as best as you can!

+1 on the suggestion for you to take a photography course. There's so many things you need to know in addition to depth of field: technical issues like when to use various shutter speeds, when to use different iso's, what the metering settings mean and when to use them, the plethora of AF settings and what they mean, how to properly calibrate your lenses to your body (with razor-thin DOF MFA is a must), how to set white balance, how to manually focus, how to make the most of a flash (you'd be surprised how much there is to learn about this). You also have a lot of non-camera specific skills to learn like composition, lighting, camera-holding technique and post-processing.

So, you did buy some of the best photographic equipment money can buy. The downside is that the pro equipment you have is more exacting and less forgiving than the amateur stuff. You have no image stabilization on your 24-70 and your primes - meaning that any flaws with your camera technique will be magnified. (You might want to consider getting a 24-105 f/4 IS while you learn).

The 85 1.2 in particular has a reputation of being difficult to use - a lot of pro's have a love/hate relationship with that lens. It can create absolutely stunning images, but you have to work at it.

Anyway, the key to improving is tons of practice and critically analyzing your images afterwards. Always think about what you would do differently on any given photograph you've taken to improve it a little bit. Most importantly, have fun with it!

Thank you!
