More excited than a fat kid eating cake!!!!

Congrats! It'll blow you away. I actually did some testing against the Nikon 600mm and my suspicion was correct, the Sony is slightly sharper and does take TCs slightly better (the Canon 600 and Sony are really close though). I'd publish a test, but it would just lead to a bunch of YT squabbling, not sometime I really enjoy.

I completely understand! Just sharing my experience with the a1 which has led to a system change from Nikon to Sony has been painful enough I don't even want to bother unless someone PM's me which happens often. To me its an eco system and the 600 was what made me decide I should try something else before dropping that much money on a F mount 600. Well as I am sure you can tell how that went lol. One step closer to going to Costa Rica with you!
 
lol! If you are in Denver I might take you up on that :) I would be happy just to hold it for a few minutes
I am sure I will be up their next year. I am in TX so not that far actually and my sister in-law lives just north of Denver. At the very least I will be passing through to Yellowstone :). Happy to meet up and let you take it for a spin.

I recently tested the Sony GM v Canon 600III in a somewhat controlled backyard test and found the Canon had the slight advantage as a bare lens but with TCs the Sony had the edge. They were very close though. The Canon was providing slightly more magnification at closer distances though.

Interesting. I too found the Sony seemed to have a little focus breathing going on, not much, but at close range the Canon did have slightly more magnification.

As for sharpness, I just looked at the results again and I can't decide which is better. It's so freakin' close. One moment I think the Sony has the edge, the next the Canon, then it looks about the same. Even with the TCs I'm just not seeing much if any difference. Super close... (Although I didn't compare 2X since I don't have one yet for the Canon).

What's really impressive is how close the 200-600 is to the 600 F/4 GM. Don't get the wrong, you can spot the 600 F/4 pretty quick, but the 200-600 isn't as far behind as I would have expected - it's really goof.

I'm constantly blown away by the sharpness on the 200-600
 
I just received word that my Sony 600F4 that has been on order for 3 weeks now is shipping to my house!

If you are looking for one I was told 70 of them just hit the US warehouse and shipping out to dealers.
Congratulations. I suspect if is much lighter than the Nikon, on par with the Canon.

I am not surprised at that result. Nikon TCs do not have the best reputation (and I find the connection to lens and body is not very firm).

I'll be curious about the new 600 F4 S (if it every materializes).

Just curious, if the Sony 200-600 isn't that far behind the 600 f4 GM, how does it compare to the Nikon equivalent (200-500), in terms of IQ? Just asking as I contemplate my future equipment investments.

If you are interested in ML, then the Nikon 200-600 would be lens to compare

I wasn't using the 200-500, so I sold it awhile back. Seat of my pants estimate, the 200-600 is easily the sharper optic. The 200-600 actually looks a bit sharper than the 300PF @ 300mm and the 300PF is sharper then the 200-500 @300mm by a smidgen.

I sold my 500PF when I bought the a1 and 200-600 so I didn't get to compare side by side. What do you think?

That one would be closer. I didn't compare them (didn't think to - I was mostly testing the new Canon 600 to make sure it was sharp). Still, I think the two would be very close. If I had to guess (and that's all this is), I'd guess the 500PF by a hair. When I tested that lens against my 600 F/4, they were really, really close. The 600 edged it out (esp towards the edges), but it was so close I don't think I could tell in actual photos.

Did you buy a Canon 600? Is it the RF version?
