TTL auto flash
• At an ISO sensitivity of 100 (200), the available shooting apertures in the Non-TTL auto flash mode are:
f/2.8, f/4, f/5.6, and f/8 (f/4, f/5.6, f/8, and f/11)
• At an ISO sensitivity of 100 (400), the available shooting apertures in the TTL auto flash mode are:
f/2 to f/16 (f/4 to f/32).
• Use of the built-in wide-flash adapter is recommended when shooting subjects closer than approx.
1m (3.3 ft.) (p. 28)
• Set the flash head at the 50° position when shooting subjects closer than approx. 0.4m (1.3 ft.) (p. 5).
