I appreciate the review. All the images seemed excellent with the 1.4x and 2x teleconverters on all three lenses, particularly on the 400mm GM and 200-600mm. The 1.4x teleconverter proved especially effective.

I find that my 2x teleconverter with my 70-200 GM II is probably the best combination. The 5.6 aperture is pretty good especially in well lit scenes. Any other lens other than the primes I think would not be worth it.

I found my 70-200 GM2 to pair with the 2x teleconverter quite well - the degradation is minimal and the resulting 140-400 f/5.6 is useful. However the IQ suffers greatly with the 2x TC on my 200-600, as you show.

Your video was very helpful. I have been debating to buy teleconverter for my Sony zoom telephoto lenses and now I decided not to. To my eyes, cropped view looked sharper even at the same ISO. Who knows what the images will look like once ISO goes up with teleconverters.

Glad it was helpful!

I’m getting into photography and I’ve been curious about these. My only comment here is that our screens aren’t really able to see any significant difference in clarity here. As an absolute beginner really, I don’t see any difference even though I know the f stops and amount of light would be a huge factor.

The 1.4x works well on compatible lenses. On the 400 prime, it is barely noticeable.
