With one 01F, hand helded
Resized pictures are even not "just acceptable"
And then ...
I was boring a day with few sun so i had a nervous breakdown
Preparation
the Target
The Result
just resized
After that... a 1.4x Sigma AF converter was boring in the bag, so i play also with it

That's not surprising at all. To me, the images taken with most 500mm mirror lenses (including the Tamron mentioned) don't look really sharp even without any converter - let alone with two of them!

Sometimes you really do say some very stupid things.
Perhaps you're not capable of getting sharp results from mirror lenses, but most certainly, the better mirror lenses are capable of sharp results.

Shooting on a crop sensor will not do sharpness any good. Using the dim viewfinder of a 350D will make it almost impossible to nail focus. (350D has no live view).

i like your double support Nelson thats a good move. But as per previous post, I think you are having trouble nailing focus by eye. At f16 (and approx T20) quite frankly your only going to land on critical focus by chance (and the stacked tc's is even worse). Good live view or a magnified evf on a mirrorless camera are, IME, the more (only!) effective tools. You could try some focus bracketing: take a sequence of pics adjusting the focus incrementally through the best focus position. For closer shots you could also use a macro rail if you have one, and focus bracket that way, moving lens + camera.
I think significantly better results are achievable, but overall I concur with you that mirror lenses by and large don't get with tc's, particularly with subjects like birds, IME fine detail contrast is quickly lost. However I suspect that careful experimentation trying, for example, to read a distant ships name could find an advantage in the use of a tc.

Ian, I don't think yout ever have shot different 8/500mm mirror lenses side-by-side with a Canon 2.8/400mm L.
Images taken with common 8/500mm lenses (e. g. Nikkor 8/500mm II, Minolta RF 8/500mm, Tamron SP 8/500mm) and FF high res digital cameras look quite OK. However, if you compare them to images taken with a Canon 2.8/400mm L, you'll immediately see the difference. And I'm talking about the Canon nFD at f2.8 - not stopped down.

Sometimes you really do say some very stupid things.
Perhaps you're not capable of getting sharp results from mirror lenses, but most certainly, the better mirror lenses are capable of sharp results. |
Here's my point.
As a reference: Canon nFD 2.8/400mm L, 100% crop from the A7RII. Standard Photoshop RAW conversion
Minolta MD 8/500mm RF
Tamron SP 8/500mm
Nikkor 8/500mm - looks misfocused, but my sample never gets really sharp (always some double-lines visible when focusing). Maybe a bad sample, even though from outside it looks very good.
Even though there's not much color it's obvious that the mirror lenses never get as sharp as a good refractive tele lens.
Remember that modern refactive lenses such as the Canon EF 5.6/400mm L or the vintage Canon nFD 4.5/500mm L are even better than the Canon nFD 2.8/400mm L ...

Good mirror lenses are sufficiently sharp. They were never meant to be the ultimate long focal distance lens. They were meant to be a cheaper, more compact an carry-able alternative for long and heavy tele-lenses. And they are certainly better than the cheap 500mm F8 stove pipes.
