Sigma 50/50e manual Auto Fill Flash Reduction, Other Flash Options

highest sync speed (1/125 sec.). Also as light levels increase, to the point of over exposure by the brighter ambient light, the lens aperture will get increasingly smaller.

With the camera in Av, Tv and M modes, the camera meter will insist on a full and proper ambient light exposure in addition to your flash exposure. It's the same thing as night flash mode in some other cameras. The background will be properly exposed by the ambient light exposure and the flash will insure that the subject in the foreground is properly exposed by the flash. However, if the light is dim, the shutter speed will get very slow, often too slow to hand hold the camera. If that happens you can simply turn the camera back to P mode which will raise the shutter to 1/60 second, but this will usually create dark, underexposed backgrounds. A slow shutter speed with the camera mounted on a tripod is often the best solution. Also, the Elan II/IIe has custom function

# 9 to keep the shutter speed at 1/125 sec. in Av mode if you want that.

I find that when using flash, setting the camera to manual mode is usually easier to keep everything in control. Since the flash exposure is being determined automatically anyway, having the camera on manual really doesn't slow much of anything down. Also, remember, that with flash the aperture effects both ambient lighting and flash lighting, but the shutter speed only effects ambient lighting. This is because the flash pulse is much faster than the shutter.

5.5 Auto Fill Flash Reduction

The Elan II/IIe automatically provides negative Flash Exposure Compensation (FEC) when shooting in bright light. If using flash with light levels above 10EV (equal to f/5.6 @ 1/30 seconds) the camera assumes you want a normal ambient light exposure with fill flash to brighten the nearby subject, so it reduces the normal flash output. This effect fades in as the brightness of the ambient lighting increases above EV10. The maximum of -1.5 stops of FEC is applied with TTL/A-TTL metering and up to 2 stops with E-TTL. This auto FEC happens in all camera modes and is designed to make your fill flash pictures more natural looking. Most people like the effect but many photographers want even more reduction for their fill flash pictures. This can be easily done with the Elan II/IIE by means of the FEC control on the camera body. This FEC will be in addition to any auto FEC the camera decides on. Some EOS cameras have a custom function to eliminate this Auto Fill Flash Reduction, but the Elan II/IIe does not.

5.6 Other Flash Options

Other Flash Options: The Elan II/IIe does not have a flash PC connector to use with studio lights and other manual flash units, but you can use a generic hot shoe to PC adapter. Nikon's AS-15 is a good quality one, but there are lower cost versions as well. With a manual or studio flash you will need a flash meter to get consistent flash exposure. Published guide numbers can't always be trusted.

The Elan II/IIe can also use auto flash units like the venerable Vivitar 283/285 or Sunpak 383. This is a way to get a more powerful flash without breaking the bank to do it. There are several big limitations however. The meter is in the flash unit and it will not take into account the lens's field of view. This can give inaccurate exposures.
