I have never found that TCs work very well on zoom lens till now as the Sony one works great.
That’s a good point. I also found that tc’s tended to amplify hidden limitations in zooms that weren’t obvious when using the lens on its own.
I recall doing a test comparing a straight 300mm (max zoom) image cropped to match one using a 1.4x Kenko on the 300mm. The cropped image was better! When the same tc was used on my 500mm prime the image lost nothing! It’s very much down to the quality of the lens they are used on.
The Sony 200 - 600 is an excellent lens. ( the 100-400 is even better) I have wondered if a cropped 400mm + 1.4tc would match the 600mm +1.4?
The 100-400 is a lot lighter and I maybe need to redo that test….it could reduce the weight of the bag.
