I am hoping the group has time to give some more advice to the dedicated sport photographer (in training).
It seems we host a house music competition and I have been asked to move to that genre, just when I thought I was safe to be left alone improving my field of choice!.
Oh well as a dedicated geek I searched through last years archive of photos and looked at the data which was available on the saved jpg images.
The photographer from last year isn't working at the school, anymore, so that line of advice is gone.
It appears all are taken with 1/60 exposure time - they look to me like they have had flash used (type unknown) by the eyes.
The ISO is on 400 the apeture vares from 4 - 5.6 with focal lengths varying from 75/170/240/300 using a canon 400D so crop factor applies.
My first thought is that a slow zoom has been used - so if I try my faster lens that should help - however my concerns are with this event I would be trying to get a small ensemble a large ensemble or a (part) of the house choir in focus i.e a wider depth of field group - unlike sport where I am only after 1 or 1 on 1 competitor and the narrrow depth of field I get when using 2 - 2.8 apeture is okay.
Also the potential problem of contrast based auto-focus could have me locking onto the shiny musical instrument and not the child performing if using too narrow a depth of field.
I will attach some examples from last year in the hope soemone else has been in a similar situation.
Each house has a full choir performance where the lighting backdrop is bright red/blue/yellow or green respectively.
Then each house has a soloist/a small ensemble 4-6 kids and a large ensemble 15- 20 kids for these the background is pretty much black.
I'm guessing the only good points are I should have freedom of movement to get to the best viewing spot.
Any suggestions as to lens choice/exposure speedlight flash yes or no - would be greatly appreciated.
I have a 24-70 2.8 on hire as a test - other than that I have 'fast' primes of 50/85/200 to use with the 7D
Thank you all in advance and maybe I'll get lucky and they might have a rehearsal time that I can get to as well!
