For the past three months, I did several shoot that involved outdoor events. Most of the time I rarely attend an outdoor coverages. Capturing the moment using telephoto lens such as Canon RF 400mm and 800mm was a relief on my end. Doing concert coverage indoor and outdoor, one thing that is important to me is to document every movement of an artist.
What’s the difference of 400mm and 800mm?
With RF 400mm f/5.6-8 IS US which is known as a compact super tele zoom, it’s lightweight than other telephoto lens. Making it portable to fit in a small bag which weighing approximately 645g.
What I like about using RF 400mm f/5.6-8 IS US, it has a large focal coverage from 100mm to 400mm.
It can be achieve up to to 5.5 stops image stabilisation. Also the said lens uses a single Ultra Low Dispersion or UD lens element with low refraction and low dispersion which reduces chromatic aberrations to deliver higher image quality.
Meanwhile for RF 800mm, it has the ability to capture in outdoor settings. It offers an incredible 800mm focal length. The lens has a fixed maximum aperture of f/11, which means it may not perform as well in low-light situations or offer as much control over depth of field.
The RF 800mm lens may come with built-in image stabilization or (IS) in which help stabilize shots when using such a long focal length. The lens likely incorporates Canon’s STM (Stepping Motor) autofocus technology, which is known for its smooth and quiet operation. Despite it has a long focal length, it designed to be portable and lightweight.
