Es gibt aber auch Leute, die das SB-600 vorziehen, z.B. Ken Rockwell:
"The SB-600 does all the things the SB-800 does that anyone really cares about and costs $110 less. You get a smaller, lighter flash with almost as much power and all the features you care about, like automatic wireless TTL remote control. Of course Nikon would prefer you buy the SB-800, so that's what you'll see promoted everywhere. Nikon doesn't go out of their way ensuring this is in stock, either.
By comparison, the SB-600 has 2/3 stop less maximum power (rated GN 98' at ISO 100 compared to the SB-800's GN 125) and thus recycles faster and provides more flashes at it's lower maximum power: 2.5 seconds and 220 flashes (Ni-MH). The SB-800 by comparison takes 4 seconds to recycle at full power and only give about 150 flashes at that power. The SB-600 has a much clearer LCD compared to the fuzzy dot matrix of the more expensive SB-800.
No built-in bounce card, so either use a white Post-It note, or tape or rubber band a business card to the top. This is the only real feature I miss compared to the SB-800.
The only things I see the SB-600 lacking compared to the SB-800 are $125 extra cost, a built-in bounce card (just use an index card and tape), no free flimsy light balancing filters (I use Roscoe gels and Velcro instead), no ability to point down 7 degrees from horizontal, no free Tupperware soft dome (you can buy one here for $17 if you want it for the SB-600), no non-TTL A mode for use with 1950s cameras (use Manual instead) and no repeating strobe mode or modeling light. I never use these things so I'd rather have a smaller flash and money in my pocket. I also think I see no jacks for the remote cords, which I never use. That's a beauty of this: slave mode is built in for free."
Was ich beim SB-600 wohl vermissen wuerde, ist die Anzeige der Blitzreichweite.
