Below is a breakdown of the gear I use, if you want to understand more about why I use what I use, I recommend reading: My Gear Philosophy: How I Choose Camera Gear for Wildlife Photography.
Full Frame Gear

Sony A7 V
The work horse, my main stills and video camera for everything, Pre-Capture was the main reason I upgraded to this from the a6700.

FE 20-70mm F4
My main travel and landscape lens on full frame, sure, f/4 isn’t the brightest, but you’ll know from my gear philosophy that it’s an acceptable trade off for me.

FE 70-200mm F4 II
Landscapes when they are further, wildlife when it’s closer, portraits, macro, it’s a very versatile lens that’s always in the bag when the situation calls for something specific my other two lenses can’t cover.

FE 200-600mm F5.6-6.3
It’s such a beast to lug around, but once you get where you’re going, you are rewarded with beautiful pictures of wildlife. I love this lens, even if it’s a workout to carry around.

FE 1.4x Teleconverter
Works on both the telephoto lenses, giving them a bit more reach, most complain of a small loss of sharpness, but I can’t say I’ve found it noticeable. Also increases macro magnification on the 70-200mm.
APS-C Gear

Sony a6700
A great camera, the additional reach from the crop factor advantage makes it great for wildlife. Now it’s used for recording myself when my wife isn’t out birding with me and I can pry it out of her hands.

Sigma 17-40 f1.8 DC Art
It’s bigger, heavier and has shorter range than the venerable Sigma 18-50mm f2.8, but by golly does this lens produce stunning images. It’s my favourite lens for everything beyond wildlife, the colour rendition and contrast is so pleasing.

E 70-350mm F4.5-6.3
When I want to travel light or hike further and still want nice wildlife photos, this lens is perfect. Whilst it’s an APS-C lens, I still use it on the A7 V as it has enough megapixels to get excellent images.
