-
- You have to use Manual mode. You set the aperture (for DOF), you set
- the shutter (to avoid camera shake) and TTL/OTF metering handles the
- rest. Usual shutter speed is 1/60th.
-
- NOTE! Watch your guide number *carefully*. The 28-80/3.5-5.6 is slow!
- Thus, stopping down too far will cause the flash to underexpose.
- Your Elan has a guide number of 12-17m (depending on flash zoom).
-
- Remember that the guide number formula is: range = GN/aperture.
- So f/8 is definitely a long shot.
-
- Also note that with smaller apertures, more flash output is required.
- You will go through (expensive) lithium batteries more quickly.
-
- If you need more kick, you'll need a shoe-mounted flash.
