Hello,

I'm looking for some guidance for a shot. Probably an easy answer, I'm a noob and jut talking it out. :) I have some older Lomo primes, all of which focus past the infinity mark. The markings become just really tiny from 10ft out to infinity.

How do you deal with cars approaching for a wide master? Would I pick my infinity, and then make marks out as far as the lens markings allow, and then try to pull with the speed of the car?

If the action in the scene stays well within the near and far of the DOF tables, are there times when you can get by with not pulling focus?

Thanks in advance,
Colin

How wide a lens we talkin' about and what stop you think? If the lenses breathe, you may be better off setting your focus at a position where you're hyperfocal, may not have to be INF, check your DoF calculator. Then if its coming towards you, follow it.

Probably a 22mm or 28mm. Day stuff mainly F8. We have similar types of shots, as everyone does. Cars coming and going in wide settings, etc. Both day and night. For the night stuff, we will be stopped down, well lit and using ASA 500.

Thanks Jonathan.

Those lenses tend to breathe quite a bit, I would set it to hyperfocal distance and not pull if you can avoid it-
Otherwise, wrap chart tape on the lens and use a fine tip pen or pencil for your marks, you can get a bit more precise, I use this technique for car commercials and long lens shots a lot.
Hope that helps.
