    Canon - Speedlite EL-5 External Flash
    4.1(30)

    $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.

      Great Budget Friendly Flash!!

      I bought this flash to mount on my Nikon Z5. I had never used an external flash before, and I decided to give this flash a try for a shoot that was going to take place indoors. Thanks to all the positive reviews and how budget friendly it was, I went with it. This flash helped me obtained the images I was hoping for. I still have much more to learn, but I'm very happy with the results.

      Great Flash

      Still trying to figure it out but I mostly shoot in the E-TTL mode which is just auto flash and it’s amazing. I’ve been needing a flash that would be pretty cheap and found this one at a local Best Buy and decided to get it. Best purchase so far.

      Great value, but heavy in weight

      It's HEAVY. I definitely do bit suggest you carry around at all times. It's great flash for the price, has amazing features on it. It's heavy, so I suggest only bring it if you intend to shoot at night. It eats through AA batteries. I believe I used it once for a shoot and the battery light came on
