What is the difference between SB 400, 600, 800, 900 flash for Nikon cameras?
I have a Nikon D60. I want to buy a good flash, but without breaking my budget. Any suggestions would be helpful? I make a lot of outdoor photography.
The most bang for the buck is the SB600. The SB800 was not done and was replaced by SB900 – if you can find one SB800 for the entire cost of SB600, SB400 Flash is buy a little good for those with a budget http://www.kenrockwell.com/nikon/sb400.htm As www.kenrockwell.com/nikon/sb600.htm http://www.kenrockwell.com/nikon/sb900.htm http:// http:// www.kenrockwell.com/nikon/sb800.htm you can see, the control mode can only be used with the SB800 and SB900
