Originally posted by Winder There are very few professional landscape or art photographers who can really afford and justify a medium format kit. I've never had a rock or a tree pay me to take its picture. The current generation of crop frame medium format sensors just arn't quite big enough to really set themselves apart from the high resolution FF sensors on the market. With FF is just too versatile compared to APS-C or the current MF options. A camera like the D850 or the A7r3 can shoot just about any subject. They might not be the most ideal for all subjects, but any competent photographer can get the job done with one of those. I would love to be shooting with a GFX-50, but its just to limiting. I need a camera that can cover a wide range of assignments. I'm not one of those filthy rich fine-art photographers.
You've got my absolute sympathies, Winder.
But to get employment in various high-end fields, you do need what's seen as the right portfolio and equipment.
In sports, a 400mm f2.8 is de rigeur, not some 55-300. In wildlife, a 600mm f4. In architecture, tilt shift. Underwater photography, a case costing as much as the body.
I've done several workshops run by a guy who's a commercial fashion photographer, has his own studio, does editorial and campaigns, and he's an F-Stoppers photographer of the month, using most often a 5D Mk III and a 50mm prime or the 70-200 f2.8.
He's just bought a secondhand Pentax 645Z because that gives him the extra quality and 'look' to take on jobs at the next level.
But it's costly.
An 'allrounder' will miss out jobs to an already established pro with specific gear, and as you realize, in the current market may never earn the money back to pay for the lens or body required even if they do go into credit card debt.
