i shoot with a 50mm 1.4 with 50D, and at night time I could pump the ISO up to 1600 ...
the main problem would be on focusing ... 1.4 is micro USM ...
I used to shoot with AI SERVO, now shooting with AI FOCUS because i don't think i know how to use AI SERVO
usually it is the subject and shooter moving towards each other ...
care to give any tips?
ai servo you have to keep pointing the af on your subject and follow. it "works" like a tracking system or a gps. but using one shot focus is good enough. just point, focus and shoot it will be done less than 5-8 sec but you have to know where your af point pointing to if you are not using the centre af point.
the subject is always moving about while you will be standing or sitting down. about the walking speed the closer your subject is the faster it appear to be likewise for far subject the speed will looks slower. you have to know at which distance you are comfortable with.
for example you intend to camp and shoot at a distance of lets say 8m away from you, you have to roughly know where is the 8m point then you wait for your subject to appear and faster shoot.. practise makes perfect =)
