I am going to race in thailand next month and the race track will be indoors, with the surrounding area letting in light, as in the picture below:
This is in singapore btw, in chua chu kang community center. It's rather bright because the CC has the shutters to the right of the picture fully open. The track in thailand shares the same lighting stance, but the track area is much larger, so the insides of the track the light will not be as strong.
Question is, I am using a minolta dynax 5, film slr. Will it be better to acquire a fast lens (e.g. 3rd party F2.8 28-70) with higher speed film (400 to 800) or invest in a external flash and use it with my kit 28-80 (F3.5-5.6) lens? I want to expose the frame with minimal blur.
