I'm currently shooting with the Nikon Z8 and the Nikon D850. Both cameras offer 45.7 megapixels, which comes in handy when cropping photos of distant wildlife. Although they are evenly matched in terms of image quality, the Z8 is my go-to for wildlife due to its advanced autofocus system, 20 frames per second, and silent shooting.
Some of my older shots were taken with the Nikon Z5o. You'll even find a few taken with the Nikon Coolpix P510 and L110.
What about lenses? I use the Nikon 24-70 f/2.8 VR or the Tamron SP 15-30mm f/2.8 for most landscapes. For birding and wildlife, I currently use the Nikkor 600mm f/4 VR in conjunction with a SIRUI AR-3204 tripod. I used the Nikkor 200-500mm f/5.6 for about two years with great results as well.
