The few modern lenses he owns are a Z 50/1.8 S and a Voigtlander 21mm f/1.4 Nokton; otherwise, he works exclusively with manual focus vintage lenses, often Nikkor Ai and Ai-S lenses.
His cameras are a Sony A7II and a Nikon Z6.
I think his photos speak for themselves, showing what's possible with the simplest, cheapest equipment and manual focus, if it fits your own area of application.
Even his BiF images are taken with manual focus and a Nikkor 180/2.8 Ai-s ED lens.
