Nikon SB-910 vs SB-700
These are Nikon’s most serious Speedlights – but what are the real differences between these two flash hotshot accessories?
01 Both flashguns have heads that rotate through 360° and tilt through 97°. However, the SB-910 has a greater autozoom range – 17-200mm on an FX camera (11-135mm on DX). The motorised zoom head on the SB-700 goes from 24-120mm for FX (16-80mm on DX).
02 The SB-910 offers a small but significant power boost over its sibling. Measuring output with the zoom head at 35mm in FX mode, the Guide Number is 34 (metres at ISO100), compared with 28 on the SB-700.
03 Both flashguns are usually powered by four AA cells, but only the SB-910 has a connector to allow it to hook up to an external power pack.
04 With more power and zoom range comes added bulk. The SB-910 weighs 510g with batteries, compared to 450g for the SB-700. Dimensions are 78x145x113mm for the 910, and a sleeker 71x126x104mm for the 700.
05 Only the SB-910 offers a stroboscopic Repeating Flash mode.
06 The SB-910 offers wireless control over three groups of remote flashguns, the SB-700 allows two groups.
