What will be the illumination angle if I use it with my Digital SLR camera?
Illumination angle of SIGMA flashguns is adjusted to 35mm film format. Therefore when using these flashguns with APS-C size digital SLR cameras, the illumination angle will be wider.
How will my flashgun (NA-iTTL) function with my Nikon digital SLR camera?
Nikon D200, D2X, D2H, D2Hs, D70, D70s, and D50 will function in “i-TTL” mode. D100, D1X, D1H and D1 will work in D-TTL mode.
I have just changed my camera system from Canon to Nikon. Is it possible to change the base of my Canon fit flashgun to work on my new Nikon camera?
As with lenses, it is not possible to change flashguns to work on different manufacturers cameras.
