Teleconverters for Mirrorless Wildlife Photography | Nikon Z7 + 500mm f/5.6E PF & 300mm f/2.8G VR II

I tested my 300mm f/2.8 VR II and 500mm f/5.6 PF VR lenses with teleconverters on my Nikon Z7, and honestly, I was surprised by the results! I think teleconverters may have a larger role to play in my mirrorless wildlife photography...

I made a video in 2019 comparing my Nikon 300mm f/2.8G VR II lens with the 1.4x and 2x teleconverters, and my 200-500mm f/5.6 zoom lens. Two questions stood out in the feedback to that review:
i) how would the new Nikon 500mm f/5.6 PF lens measure up?
ii) how would the 300mm lens get along with the 1.7x teleconverter?
I've been promising this video for quite a while and part of the reason for the delay is that I didn't think the test would be interesting - I was sure the 300mm and 1.7x converter would be no match for a 500mm prime (I was right). However, more and more I'm coming to realise that many of the traditional issues of teleconverters are not relevant to mirrorless, so I thought I would try out both my wildlife lenses with my three teleconverters and see how they performed with my Z7... I was very surprised by some of the results, and will definitely be thinking differently about teleconverters in the future!

Disclaimer: Results are likely to vary a little between different camera bodies (or even copies of the same lenses etc.), so your mileage may vary. For the autofocus speed tests, I don’t have a DSLR camera body to test with, but assume that in good light the AF might be faster, but probably slower or unusable at higher maximum apertures.
