My new credo of life is: never leave home without at least one strobe, even it is midday and the sun is high in the sky. This time i've used two little's. Vivitar 285HV & Metz 48-AF1. Set up is very simple: both were on the ground, camera left and right, Vivitar bit more away from bike, Metz zoomed at 50mm. both at 1/4 power. The upper image was taken with Tamron 70-200 f/2.8 lens.
Upper image Exif: Exposure 0.008 sec (1/125)
Aperture f/4.5
Focal Length 120mm.
Lower image was taken with little Tamron brother 17-50mm. f/2.8 lens.
Exif: Exposure 0.04 sec (1/25)
Aperture f/8.0
Focal Length 19mm.
Whole system triggered by Cactus V2s radio triggers. With little tamron they works perfectly, but when i mount 70-200 f/2.8, then.... hummm... i start to think about transmitter modification, because the signal is too low to reach receivers when i am far away :(
