Frequently Asked Questions - SL-57 Genaray
How do I mount the SL-57 flash on my camera?
Slide the flash's hot shoe mount into your camera's hot shoe until it clicks securely. Tighten the locking ring to prevent accidental disconnection.
What batteries should I use?
Use two AA batteries, preferably rechargeable NiMH for faster recycling times. Alkaline batteries work but may have longer recycling times.
How do I trigger the flash wirelessly?
Set the flash to wireless slave mode and use a master flash or a separate trigger. The optical sensor on the front of the flash will detect the signal.
Can the flash head be tilted for bounce photography?
Yes, the flash head can be tilted from -7 to +90 degrees vertically and rotated up to 270 degrees horizontally for flexible bounce lighting.
What is the guide number and what does it mean?
The guide number (GN) is a measure of the flash's maximum output. With the SL-57, the GN at ISO 100 and a 50mm zoom position is 33. To calculate aperture, divide the GN by the distance in meters.
How do I clean the flash and maintain it?
Wipe the exterior with a soft, dry cloth. Avoid any liquids or abrasive materials. Do not clean the sensor with a brush; use a lens blower if needed.
Is the flash compatible with my mirrorless camera?
The flash uses a standard hot shoe connection, so it is compatible with any camera that has a universal ISO hot shoe. For non-ISO mounts, you may need an adapter.
What does the red indicator light mean?
The red light on the back indicates the flash is charging. Once it goes off, the flash is ready to fire.
Can I use the flash as a slave without a camera?
Yes, set the flash to manual slave mode and it will trigger when another flash goes off. This is useful for multi-flash setups.
How do I update the firmware?
This model does not support firmware updates via USB. Check with Genaray support for any available updates or visit their website for further guidance.
