Abstract: A distance metering device of a camera eliminates a troublesome re-setting operation when a remote controller is used as a cable release and avoids the creation of defocused photograph when the remote controller is used as a self-timer.When a first remote control signal receiver is selected, that is, when the remote controller is to be used as the self-timer, a distance metering mode of a multi-point distance metering device is forcibly switched to a multi-point distance metering mode, and when a second remote control signal receiver is selected, that is, when the remote controller is to be used as the cable release, the forced switching is not done.

Abstract: This disclosure is concerned with novel, submersible cover designs for pools containing fish, such as salmonoids and the like, including vertically separated and stacked light-opaque covers that divide the pool into dark zones in which the fish are trained to rest in stacked formation with accelerated feeding habits and with a plurality of openings in the covers to provide a plurality of feed regions along the surfaces of the covers.
