Advice!!!

[superted666]

Ive been asked short notice to do a shoot tonight at a lake near
by, the event is a canoe combined with cable pull kinda event. Pics
will make sense.
Basically im shooting a lake where canoes will go past approx 25-35
mph on a relativley set path so i can prefocus to save time.

I only have the a100s two kit lenses so they are not too fast to be
honest (18-70 and 70-300)

I will be using a tripod and light will be moderate its around 6pm
so daylight but without the midday sun )if we get any, its overcast
at the moment!)

Focal range will be at the corners of the lake so closest i can get
is probably about 20 meters away.

I need tips and advice from your knowledgable minds!

Um.....I don't know. Shoot in RAW, and underexpose a bit? I'd rather underexpose a bit if it's the difference between a blurry shot and a sharper photo. Not sure about what the lighting is like, but it should be ok. I'd also use a shorter focal length and crop afterwards. Motion blur won't be as great if you use your 70-300 mm at shorter focal lengths. Plus, the lens is faster at shorter focal lengths as well.

Bump the ISO up (I know... the noise will rear its ugly head) sp you can get reasonably fast shutter speeds.

Pan, pan, PAN!!!! So unless your tripod has a pan head, or you can get you shutter speed around 1/1000, don't use your tripod and just handhold.

Regarding pre-focus: I don't know if your Sony can do this, but you can set a "trap". Set the camera to manual focus, focus shutter release priority, focus on where the canoe is going to be and hold the shutter release button. When the canoe enters the correctfocus plane and focus sensor, the shutter should fire "automatically".
