A slightly longer two thirds of a stop faster lens I don't think of as virtually the same, but YMMV. With regard to a high end crop APS-C camera, you do realize that an A7r III does basically double as one when you use it in crop mode. It makes a quite decent 18MP APS-C camera with a nice viewfinder, lots of frames per second and quite good AF. That will be even more the case when it is replaced with a 60MP FF camera, which I expect before long. That camera will be a 26MP in APS-C mode and will be pretty much anything one could want in an APS-C camera except having a stacked BSI sensor that would allow even faster sensor read out. So, I think that 200-600 lens could certainly be used well on the Sony system.
With regard to other lenses I do think we will see a smallish 300 f/2.8 by the end of the year, announced at least and available for the Olympics. I also think it is interesting that it looks like a 500 and a 300 f/4 are going to be conspicuously missing from the Sony line up. I think they would be very smart to make those lenses PF/DO lenses and that may take a bit more time, but I would love to see Sony make competitors for the Canon and Nikon lenses....Show more →
Why don't you consider it virtually the same? Close enough to me. One might be better, as we will see in reviews, but a 40mm difference and 2/3 of a stop isn't much. And weight/size matters too. If I need to switch, I will. It is just weird to have to trade monetarily in a downwards direction for something better. For similar reasons, I feel bad for Sony users who spent $10k on the 400 2.8 if they really would have preferred the new 600 f4.
No, for wildlife the a7riii is not good enough imo. It is why I bought the A9 afterwards. The autofocus is lacking, the tracking is lacking, and it has blackout. The a9 is completely silent and shutter shake free, great tracking, 20fps and blackout free. I would never shoot with the a7riii for birds. I've done it. I don't like it. It would work for landscapes, but for me at least, I am talking about birds in flight.
With the way Sony has gone about releasing lenses, I honestly don't see a 500 PF competitor in the future. Fingers crossed though.
It is funny, I have spent the past 2 days(I am on the opposite side of the world right now, so the news broke midday for me), what I would do with the 600 f4. I've gone birding with my friend who uses the d850 and one of the Nikon 600 F4s. It is just a monster and is always carried with the additional weight of a tripod. When something comes at an odd angle, there is just no way to adjust. It is cumbersome to say the least, even with a high end and smooth moving tripod. I could just move, crouch, etc, and he couldn't. Also, by the time he put down the tripod and moved it around, some shots were gone. It just goes against my personal style to give up mobility. I mean, I get that it works for some people, my best friend included, but I still have to shake my head(As I am sure people do when they read my posts!).

. You have the notion that all Canon lenses are manufactured at automated assembly lines. It is true for some lenses, maybe even for the majority of lenses but not for all lenses. Not for their super tele lenses, for sure. And Sony is similar in that respect; they don't manufacture all their lenses by hand. That's all I am trying to convey.
