On the question of 1.4x vs. 2x, the image quality of my 1.4x is far superior to either the EF 2x or EF 2x III that I tested at comparable focal lengths. But I wonder if the 280mm you get with a 70-200 + 1.4x will be long enough for your needs. Most of my airshow photos of planes in flight are done at 400, 500 or longer focal lengths.
In reply to birdbrain • Mar 8, 2021. For zooms like the 100-500, no. I have owned every version of the EF 100-400 & 70-200 f2.8 and I was near happy with the results of the 2x extenders. The 2x extender can add value on the EF Big Whites, you will loose some IQ but the results are acceptable (and at f8 in most cases).

Yes. 14 Jul 2012. #1. Maker/Provider: Canon. Product: Extender EF 2x III. Price: Around £400. Overall Rating: 8/10. Overall Summary: An effective way of doubling the focal length of a compatible lens, with the penalty of reducing the maximum aperture by 2 stops.
Designed as a lightweight and affordable extreme telephoto prime for Canon RF-mount shooters, the Canon RF 600mm F11 IS STM is a versatile lens for casual wildlife and general photography. If 600mm isn't enough for you, it can be paired with Canon's new 2X extender for RF to become a very portable (and very slow) 1200mm F22.
The Canon EOS 2000D produced images of good quality during the review period. This camera produces noise-free images at ISO 100 up to ISO 800, with some noise appearing at ISO 1600. The faster setting of ISO 3200 is still usable, although we'd suggest avoiding ISO 6400 and especially 12800 if possible.

The Canon EF 100-400mm f/4.5-5.6L IS USM Lens has an excellent focal length range that includes the longest focal length found in a Canon zoom lens - 400mm. This long focal length and focal length range combine with very good image and build quality to make the 100-400 L one of the most popular serious wildlife and sports lenses Canon sells.
