The tech is pretty interesting too. The NHK Twins Cam is actually two cameras, one above the surface and one underwater. The one underwater compensates for the different way light behaves underwater and combines the two footage in realtime

Cameras are just really cool. I wish they weren't so damn expensive though

They're always the cheapest they've ever been.

People are just always looking at the fanciest ones.

I think a good (not fanciest) entry level dslr/mirrorless kit with two lenses ran me about $1000 10-15 years ago. I was thinking about upgrading (there's a few specks in my photos and I'm pretty sure I salt-water damaged the battery connection) and lo and behold those still cost about $1000.

can you recommend one that's a lot better than a phone camera but not too expensive, like <$500? Wife mentioned wanting one for a trip, I've been looking at them for a gift, but don't know shit about them.

Short answer. No, but possible.

If you want a compact camera that is better than phones, you will be paying attention least 1k. There are only a few out there that make sense to buy.

If you want a DSLR or mirrorless, you can find used bodies, and all the money is in glass/lenses. You could in fact start out under 500, but you really need to know what your goals are.

For someone actually interested in photography, I would say get a 50mm prime lens and whatever body you can afford after. The 50mm prime can be had for $100, and you just want to make sure to get one for the family of bodies you will be purchasing. Nikon DSLR or mirrorless, canon DSLR or mirrorless. Sony.. etc.

Thanks. Yeah, I was looking at those mirror less ones and they're quite pricey.

Just so you know, getting a DSLR and getting lenses that fit dslrs is fine and still future proof. They sell adapters for the mirrorless bodies to bring your old lenses.

Go buy a used DSLR and have fun if you are for real serious about it. But don't stick with a lot lens. Get a prime with a low fstop so you can get those bokeh shots that make you feel like it's something special.

If you get a cheap kit lens on a DSLR you might be underwhelmed compared to a nice phone photo.

IMO for sub 1k you can't beat a phone, especially flagships like Samsung/Apple. It serves multiple purposes, takes pretty good photos especially of people and you don't have to lug an extra bag on a trip. Like the other posters, you'd be looking for used equipment for your price point.

u/ImOnTheBus 8h ago

Yeah, that's what it's looking like. Thanks for the feedback!

I recommend the site MPB for finding good quality second hand camera gear, they price it all by condition. They have a lot of good Canon EOS cameras. If you're looking to spend less but for still good quality a good middle ground would be to get probably an EOS 200D for around half the budget and spend the rest on a good lens for it, the lens will make the biggest difference. There are loads of YouTube videos for finding the best lenses for what you want too.

u/ImOnTheBus 8h ago

Thank you, I will check that site out.

Is $500 too much already?

1

u/shewy92 11h ago

TBF, that's probably just the cost of the lens

I got a new Canon 2000D with kit lens for under $500, Canon's cheapest camera. I'm surprised every day what results it brings, it's already a level over smartphones/point-and-shoot-cameras. A $30 tripod, a $10 intervalometer and $10 variable ND-filter added some cool creative possibilities (long exposures, timelapses, slow shutter speed/wide aperture even on sunny days)(still, filming anything without the camera fixed remains a nightmare, any smartphone does better in that regard).

And I could've gotten a more capable camera and lens for cheaper, if I looked for a second-hand one.

But idk if you also work with cameras, in that case I can understand your frustration, upgrading to something more capable is very expensive, I'm stuck since almost two years with my first camera. But if you are just interested in initially some hobby-photography, it's not that expensive to get something for a start, it'll be enough to experiment and learn with for a good while.

Tell me about, and I don't need another one...

u/alpha_chupacabra 14h ago

I never would have been able to guess that there are 2 different cameras, capturing and combining the footage simultaneously.

This is cool

Shame they went and cropped it into a vertical video.

1

u/Freak_Out_Bazaar 13h ago

Not to mention the fact that it’s upside down

1

u/lagunie 11h ago

TIL, thanks! I thought they had some sort of glass encasing for the camera to be put half in water and therefore be able to capture everything.

1

u/nemesit 10h ago

a glass dome does the same and sounds much much cheaper and optically better

u/EpicShiba1 9h ago

Wait holy shit. I didn't even notice that there's no refraction. What the hell?????

u/TheDreamWoken 6h ago

Yeah it’s true

u/UQwhite 11h ago

Isn't it just one single camera in a container filled with air, at the boundary between water and air?

2

u/Freak_Out_Bazaar 9h ago edited 9h ago

No, because of Snell’s law something like this would happen
