"...shallow pocket hobbyist..." That is a great term! Some people order a camera as soon as it is ready for pre-order. Others wait for used and refurbs.
I have very shallow pockets. Especially after buying a 11 lot of sapphire that are 6.147 average carat weight. Lol lol. Glad I have all the camera equipment I need and a lot I don't. Lol

Note the word "experiment" I just wanted to see the difference and check out the accuracy. No big deal, sorry some got their panties in a wad.
Guess we'll never experience an attached version?

Let me be perfectly clear, a TC never MANTAINED image sharpness, EVER, NEVER. There will ALWAYS be a loss in image quality, no matter how small it seems.

Optical degradation isn't an opinion issue.
It's a physics issue...not a debate.
TC's degrade images...every time...to some degree.

It certainly struck a nerve with some readers but for myself, thank you for taking the time and effort to "Experiment". Sometimes the often repeated "Facts" that are used to guide decisions about photography are not absolute or that the "Facts" are no longer applicable. Again, thank you. By the way, your examples did not really look that soft to me.

It works very well at the size presented = success.
Modern shake control produces what used to be a miracle.

If you want to demonstrate you success or failure, you'll post and store your example images. Rather than creating wasted space thumbnails and wasted time reading your post. If this post had any amount of seriousness, create a replay and store the images.
Wow! Shouldn’t have wasted your time reading the post, eh.

400mm with a 2X is 1200mm... not sure how that works... Is DX mode a digital expansion???
First off I would set ISO to at least base ISO, then open the aperture wide open to best see where the weakness will be with the lens. Then set a much higher shutter speed to match the focal length if experimenting hand held.
You should expand the 400mm image to 800mm (crop) to see the difference in what you loose or gain with the 2X at 800mm... both images need to be identical in size to see the results.
Confusing post...
for Canon many times you are better off cropping than using a 2X... and for a sharpness test It is best to use a tripod.

First off, a zoom is NOT as sharp as a prime ever, and not sure IF you employed a tripod with timer to make the image, which both would help the final result.
Second, using a TC1.4x would likely be SHARPER than a TC2.0x
third, as others have mentioned, a stationary subject is ONE thing, attempting a moving subject not the same, results and ability of the camera to capture will be affected particularly with a TC2.0x.
fourth, IF you are NOT entering contests or attempting to get published, it doesn't matter all that much, but IF you post here, viewers are hypercritical usually.
Good luck
