    Canon - Speedlite EL-5 External Flash
    4.1(33)

    $299.99

    The Speedlite EL-5 is a newly designed flash that receives many features from the flagship Speedlite EL-1 while also including modern features all its own. Two popular features found in the EL-5 are the modeling lamp and the use of the high-capacity LP-EL rechargeable lithium-ion battery pack. The modeling lamp aids the photographer in seeing the effect of the flash’s light emission, including providing an idea of how shadows will fall on a subject. With this battery pack, and firing at full 1/1 manual flash power, the Speedlite EL-5 emits a guide number of 60m/169.9ft @ 200mm (at approx. ISO 100) with the ability to recycle to full power in just 1.2 seconds, and with the potential for up to 350 full power flashes being possible on a single battery charge. To improve working with the Speedlite EL-5 the joystick and select dial from the EL-1 are featured making operation easy, so adjustments can be made quickly, while shooting. Additionally, the new Multi-function connector at the EL-5’s “foot” enables advanced communication on multi-function shoe equipped cameras1 providing more customization and control to be shared between the flash and camera. **Important: because of the transition to Canon’s Multi-function accessory shoe, please be aware that Speedlite EL-5 cannot be mounted or used on Canon cameras with other accessory shoe designs.

      returned godox 860iii for this

      Compared to the Godox 860iii, the 46 is smaller and feels lighter. It moves the same, although notchier and harder to turn horizontally at first. I can also stand the camera on the lense hood w/ 35mm 1.4gm. I couldn’t do that with the Godox without it falling over. The hot shoe connector slides in like butter. The locking mechanism has a cover to protect the connection. The build definitely feels better. I’m happy with the performance. I don’t think it’s as bright but very close.
