On one hand, @EduPortas totally nailed it: price hikes are pretty much everywhere. This is a mature luxury market, so manufacturers can kind of do whatever they want. An item's price really just comes down to what a customer's willing to fork over. Before they even put stuff out, they do all these market studies. Nowadays, a camera's a luxury item, while a smartphone? That's a commodity.
Then again, the market's shrunk so much that all the costs just get dumped straight onto us, the customers. We've talked about this tons before, and honestly, my take on it is still spot-on:
Personally, I'm always looking at the underwater photography and video gear market, and prices there are just going through the roof. If the camera market itself is a niche, just imagine the market for people who take cameras underwater – that's like the niche of the niche!
Anyway, the biggest jump in prices happened around the pre/post-pandemic time. After that, things stayed pretty steady. But now, with those American tariffs, we're seeing price increases hitting the whole world. Basically, manufacturers are just spreading those tariff-driven price hikes across every market globally.
For example, let's look at a Nauticam underwater housing (from Hong Kong) for the Nauticam Sony Alpha 2020 (for A9II and A7RIV). The price was $3048 USD in June 2020, then it went up to $4127 USD in July 2022, and it's currently $4700 USD as of May 2025.
The Nauticam Sony Alpha 1 housing cost $4540 USD in July 2022, and its price remained pretty much unchanged until the Trump mess, when the price jumped to $5000 USD.
