not sure the assumptions are correct
Heck neither am I! Thanks for hearing me out though.
There are just under 150 professional sports teams in North America and there are 350 Division 1 schools in the NCAA
OK, and US sports revenue is 75B/year vs. 500B/year for the world. In other words the US is 1/8th of the world sport business. If we equate US with "North America" in your team count, we could say if there are 500 good teams in the US, there'd be 4000 good teams in the world.
So if all sports photogs in the world were attached to such a team, you'd need 5 photogs per such team for my estimate of 20,000 to be reasonable.
Also note the summer Olympics has 2,000 photographers (winter 700), so I would need 10% of the world's sports photographers to be Olympics photographers for my estimate to be reasonable. Curious what percent you think that might be? I almost feel 10% might be high.
Actually I just made up the number after thinking 30 seconds :-D But it could actually be right :-D
At the top tier level (professional sports and NCAA Division I Universities) the photographers are not covering just one team in one city, but are traveling from city to city covering games
I had overlooked that, good point but still, how many teams would they cover?
the real money and real demand is always in wealthy amateurs who have disposable income and no need to balance the expense against earnings
I think it depends on the type of lens.
Like the forthcoming 35/1.2? You don't need that for sport, wedding, nature, travel, architecture, reporting, fashion, portrait, product, landscape. But well-heeled amateurs are eager to see it. I'm dying to! In fact I hope it's a 35/1.0! It's 99% amateur, 1% professional fine art maybe? To the extent professional fine art really even exists? Probably same story for 35/1.8 (at a very different budget point), 50/1.8, 50/1.2, 85/1.8?
But a 200-500/4? This seems useless even for a rich amateur's family photos. You'd get the 100-500 and the 135/1.8 for the kid's sports games and portraits of the wife; if you had a 200-500/4 it'd never leave the house. Only if the amateur were into nature photog would it make sense and even then not sure it's long enough (but yeah, TC). I might be wrong but I'd guess this is like 80% pro (sport and some nature), 20% amateur, or something.
