Advice needed for model shoot

Advice needed, i have recently joined a photography club, they are soon to have a practical night, they hire a model and set up lighting.
I have never tried this as i normaly shoot wildlife, so i wonder which of my lenses will be best suited t this type of photography? Canon 24-70mm or 70-200mm. Would i need to take a flashgun? sorry if these are daft questions.
Any tips would be most welcome.
regards brian.

Why not just take both? Both lenses are good for portraits, the 24-70L for wider stuff and the 70-200 for closeups and headshots.

If you *have* to take only one, then the 24-70 would definitely be the more appropriate. I would definitely take both though unless you have a good reason not to. I've used the 70-200 as a portrait lens at times with good results.

Why are you asking? Take your bag and you will have all your lenses and your flash. You probably won't need the flash as I assume you will be using studio lights or natural light. However it won't hurt to have it.

I use the 24-70 and 70-200 for all my shoots. (Oh and ocasionally the 100 mm macro)

It depends on how many other photographers will be at the shoot.. In my experience these nights usually turn into a "media scum" with photographers pushing and shoving to get "that" shot.. The trick is to stand back and stand on a chair or similar to get above the pack.. Your 70-200 will be perfect for this situation..

If club is using studio flashed with triggers use your flash on the lowest possible setting to trigger the flashes.. It the club is using tungsten photofloods for lighting set your white balance to tungsten or custom white balance to around 3200K.. You may have to use a higher ISO setting at around 800ISO or even higher to arrest any camera shake or subject movement with a highish shutterspeed.. Don't be affraid to use a higher ISO setting but remember to overexpose by 1/3 to 1/2 stop.. A monopod or 3pod will be handy with tungsten lighting..

I just finished a group photoshoot. I barrowed someones 24-70 and LOVED it. the 70-200 did not work in the small area. At first it was push shove but after a bit things slowed down and everyone moved to different models and got more personal time with them. I was really impressed with how this was run. I found myself shooting between 35 and 55mm.
