Too funny.
It may not pay, but it helped keep my sanity during the pandemic.
Plus, hobbies are expensive. Things more expensive than a 600 mm lens.....hmmmm: Harley Davidson Low Rider; pair of jet skis; fishing boat & trailer (never mind the truck needed to pull the trailer); ok..how about that truck to pull the trailer....
After that, your 200 f/2 or 600 f/4 seems downright affordable!!
