Tariffs are basically factored into the cost of goods, and then that itself is going to factor into the markup once or twice by the time it reaches the end retail customer. So you can take those alleged tarriff percents and multiply them by 50% or so. And if middlemen decide to game the system and simply blame the tariffs in return, it could be even higher.
The only recourse dealers are going to have is to make little or zero profit on the cameras and gouge us like hell on everything else. Lots of auto dealers have long made essentially no profit on their new cars at all, and more than made up the difference in charges for parts and shop services, along with flagrantly dishonest service dept practices. That's only going to get worse. But people who can afford a Porsche or BMW probably don't care about an increase anyway; spending a lot is almost a status symbol to some. But if you want an affordable Kia? Camera equip is analogous. Some just care about status purchases, regardless of whether they're going to get better pictures or not.
What concerns me about film is how dependent the coating lines might be for particular film bases from different countries. Kodak specializes in PET base manufacture, others in acetate. With fewer sources for the special types needed, how much trans-Atlantic cost increase might be involved, especially if demand winds-down even more due to tariff complications? The last tariff round, which was far less drastic, I witnessed a lot of US startups and smaller manufacturers (some relatively big ones too) simply crash because they couldn't affordably source necessary supplies any longer. Then the pandemic hit. Now this too? !!!
