Originally posted by Rondec My experience with radio triggers is that they are a lot more consistent and dependable than using optically fired slaves. Both work fine, but the newer radio triggers out there are very nice.
Roger that. Don't know what they are today, but the k10/K20 used to be limited to 10 ft. while even cheap radio triggers can go 100 ft or more. For Pentax, they only work in manual, but i find that manual is more easy to figure out than PTTL - and one doesn't have the blinking on the TTL preflash. On a few occasions i set up scenes for promo shots, and shifted the radio trigger from my K5 to a friend's Canon and he would take a few shots without changing anything on scene. Manual is great. And today's Cactus apparently let one adjust power levels remotely with a compatible cactus flash. And one radio-triggered flash can be used to trigger another flash in light triggering mode. Too easy. I've shown the scene below before - a 30-45 minute promo for a supper play and the actors had such fun that they carried my stuff back to the car for me
When i told the director that i wanted to do the promo outside in a baseball field, she said "are you sure, its going to be dark by the time one actor gets off work". Answer: yes - i have a flash
. Cheap ass flash but the light is the same from a $50 flash versus an $800 nikon flash.
You can't get shadows like this with an onboard flash.
