The more recent EF 1.4x Mk III and EF 2x Mk III Extenders don't stack together because Canon was attempting to discourage this. Using TWO extenders at once has a dramatic and destructive effect on light transmission (towards the edges of the optics) and optical integrity. Manufacturer description: Designed to extend a lenses focal length by a factor of 2x, the redesigned Canon Extender EF 2X III delivers optical performance on par with the finest Canon super telephoto lenses. Re: Canon EF 2x III Extender - Sharp, Practical & Useful. In reply to Igor Sotelo • Jan 8, 2021 2 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. An f/2.8 lens can take a 2x TC and still be only an f/5.6 aperture, so it will still AF on any Canon body. These are certainly more expensive than the $1800 100-400 L, but older used ones can often be found on eBay and Craigs List for around $3000 to $3500 (original non-IS versions), and starting around $3500 to as much as $6000 (IS versions). 024.6652.7434 - 0938.338.315 - 0909858266.

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. This means that the Canon 300mm f/4 lens can be used with a 2X teleconverter and still autofocus. I recently tested the Canon 5D Mark III, Canon 300mm f/4 lens, and the Canon EF 2.0X III Telephoto Extender out while photographing birds. This was a test prior to leaving for an Alaskan cruise. It wouldn’t be possible to bring the Canon 500 f/4 The Image Stabilizer function cannot be used with the cameras *2 listed below.
