Last one. I have to experiment a lot more, but using this with a Sunpack 433D (I'm on my third one, having used this flash since 1984) produced some significant nighttime fire scene images, which are some of the toughest to shoot in my opinion. I plan on upgrading the lens to a 24-240 f3.5-6.3 zoom lens which should give me a single camera solution. I am very interested in your opinions.
