A6300 + 2x tc + 70-200 2.8

This is my next sports wildlife setup, now what do I sell...

Yes that could work well. 2X at 20 giving 400 plus the 1.5 crop factor gives 600mm equivalent focal length.

The new tracking AF should help a lot as well.

A7rii in APSc mode may be very similar. It still gives 18mp plus it has IBIS and most likely better high ISO performance. All at a cost though.

An alternative would be the Canon 70-200 F2.8 L, Canon 2X tcc and Metabones and A6300. That would be cheaper. Assuming the Canon TCC will work that way.

The a6300 will have much better dr than using any ff sensor in crop mode, both dr and iso take a huge hit when using crop featurea. Better to use cameras as they are designed for!

In 4k video too, in theory this looks like it may be a better performer than a7rii in both noise and dr, probably a little bit below the a7sii 4k performance, however, it might even outperform it!

A kidney and your first born? It's going to be a seriously expensive lens/ TC

The new lens has OSS, so no IBIS shouldn't be a problem. http://www.sony.com/electronics/camera-lenses/sel70200gm

This is going to end up an f5.6 lens. Usually a 2x telleconverter degrades the image over a 1.4x. However, since both the 2x and 1.4x are made with this lens in mind, maybe the results will be ok.

Sony says the 2x converter loses 2 stops of light, the 1.4x 1 stop.

How much do you think the 70-200 and converter will cost? $3.5k?

Why use a 2x teleconverter, which substantially degrades IQ and costs 2 stops? If Canon mount lenses work on the A6300 as well as they do on the A7Rii, you should consider one of the Sigma 150-600 lenses or the Canon 100-400ii. I'm sure that either would produce better IQ than the suggested combination.

All reports I've seen seem to suggest that the a7rii has problems with long third party lenses. The a6300 probably will as well. Do you know of any positive reports?

There is no reason why either range or quality at high ISO settings should be any different if a Sony (or a Nikon) FF camera is used in crop mode. Resolution will be lower, obviously.

A converter that is designed at the same time as the lens, and specifically for that lens, should lose little if any image quality. It is not like the traditional cheap third-party converters.

It is axiomatic that teleconverters sacrifice image quality, some more than others, and 2x converters are worse in this regard than 1.4x converters. Whether the IQ loss is acceptable depends on the quality of the lens, as well as the converter, and the application. In addition, a 1.4x converter generally loses a stop and a 2x converter generally loses two stops. And, that can impact autofocus.

I tested this statement out and found it to be inaccurate. I don't think there is a reach factor effect with the a6000 worth noting over the a7rii.

Shooting indoors with the same crop lens and same distance to the subject, the a7rii significantly outperforms the a6000 in BOTH sharpness and noise level. I set it on aperture priority and let it pick shutter and iso to simulate real world use and take advantage of IBIS. ISO of both was selected at the same value anyway.

I don't think the loss in MP of the a7rii is relevant unless you have great light and a scene where you can capture the dynamic range naturally in the a6000. I think I'd take DR of the a7rii over the extra pixel count since pixel count doesn't seem to be a benefit given the higher noise levels. I'd take the 6 oz heavier a7rii for the DR advantage and just pick crop lenses to save weight.

Only time I'd pick the a6000 would be if needing frame rate higher than 5fps.

The better sensor for noise and IBIS in the a6500 may change this some, but guessing not enough to dismount the a7rii advantage.
