Camera Flashes from popular brands such as Canon and Nikon
Camera flashes are almost as essential as a lens when it comes to taking to amazing, high-quality photos. A flash is essential the natural lighting is not working in your favour. Built-in camera flashes generally create generic images, whereas external flashes can really help to bring your image to life.
The power outage is arguably the most important aspect of a flash as it determines how much light the accessory is going to emit. You are going to want to look at camera flashes with high GN (Guide Number) ratings. However, flashes with high GNs such as the GODOX AD200 and the Canon Speedlite 600EX-RT can often be rather expensive. However, it may not always be appropriate to use a high GN flash, and products such as the Nikon SB-300 Speedlight may be more appropriate for smaller cameras, such as the Canon EOS 700D.
The recycling rate of your flash is another crucial feature to consider before buying. The recycling rate determines the amount of time there needs to be between two flashes. In most cases, you are going to want to look at buying a flash with a fast recycling rate at maximum output. A fast maximum output recycling rate will ensure you can use your flash at its highest power as quick as the accessory allows. The recycle rate on cameras from popular brands such as Nikon and Canon are around four to six seconds.
You will find TTL Metering in most modern external flashes. TTL metering uses a series of instantaneous light bursts to determine the optimal flash exposure pre-shot.
An auto-focus assist beam helps to create brighter, more precise images that are considerably better than a camera's internal flash, which can be rather intrusive.
Auto zoom determines the distance from your camera to your subject determined by the zoom function in the camera. The flash is automatically adjusted to the focal length to ensure you get the best possible coverage with an efficient use of light.
