The superb Sony A6700 APS-C Digital Mirrorless Camera
I moved to what I consider my holy grail Sony wildlife setup back in 2023 with the Sony 70–200mm GM II paired with the Sony 2x Teleconverter. That gave me an effective 400mm of reach, and when combined with the 61 megapixel sensor of the Sony A7R IV, it allowed for heavy cropping when needed to squeeze out a bit more reach.
