WoW, I hear where you're coming from. From way back in my film days I still have my FD 600mm! It's a beast. I do have adapters for both dslr and ML. For dslr I have an Ed Mika adapter and a typical adapter for ML. I've taken it four spin on my ML and it's not to hard to use with focus peaking. I find the biggest problem with all that really high-end glass is not that it's not sharp because is but the amount of fringe they have in bright light! Of course post can mitigate most of that. But the EF 500 with a 1.4 is just flat out better!!!At least my EF 500/4.5 L is handholdable and works very well with EF 1.4x III. My 800mm is the FD 800mm f5.6 L. It has CA but is still sharper than the 500 and 1.4x combo. Focus trapping works well at 10fps.
An EF 600/4 L IS original is really the only alternative that I can possibly justify. With a 1.4x it should beat the 800. I often use the 800 and 1.4x for motorsports, hence the desire for a 1200mm lens. The 600/4 with 2x could be the ticket.
Seems silly, but I'd have to keep the 500/4.5 for a "light" lens! It didn't cost me much so I'd risk the loss of focus.
That FD 800 must be a REAL BEAST!? my 600 weighs eight pounds with no IS or AF!!!
