I’ve found a number of inexpensive zooms to be bad. I’ve found them to be really bad with converters. I’ve found expensive Canon zooms with Canon converters to be pretty good, but not as good as the zoom itself.I shoot regularly near and far with telephoto lenses ranging from very sharp expensive primes to lower priced zooms and can always get sharp shots. For about $2000, you can get some spectacular zoom lenses. The Canon 100-400mm II is really sharp. The Sony 200-600mm is used by some of the best bird photographers. If you think the f/11s are going to be sharper, just look at the Digital Picture comparison of the 600mm/f11 with the Canon 100-400mm zoom at 400mm or 560mm f/8 with a 1.4xTC and the Sony zoom at 600mm/f6.3

Also my copy of the Sigma 150-600mm C at 600mm is sharper than my 100-400mm II at 560mm. So, I am puzzled why you find the zooms pretty bad.
but the mistake you guys continue to make here is that these are very light as well as being inexpensive. But neither of the combos will get you to 800mm. I’m not interested in looking at charts and crap. I’ve looked at the full sized RAW images from a number of people on YouTube, and they look great. It’s interesting that everyone I’ve read who have actually used these lenses give them a thumbs up, but those who haven’t can’t seem to stop criticizing them.
