Choosing what camera to buy is always fun :D
Doing research, reviewing all the specs, sample shots, online reviews, articles, comparing prices, features, performance, build quality, etc.
Nowadays, it has become even more exciting given all the recent developments in the world of photography equipment and processing. Many aspects of photography are now affected by computational operations done in specialized software and hardware components in smartphones. Seems like this is not (yet) happening on proper cameras.
I am currently in the process of choosing a travel camera, and having done some research already I have come to a conclusion that before looking for a camera, you have to define what are you looking for in a camera, in other words: what do you want.
This might sound obvious, but when you start looking at options, you might get overwhelmed. Firstly, there's so many to choose from! Secondly, there are features now built in cameras that you have never dreamed of. Third: developments in photo abilities are one thing, but modern cameras are also great videography tools.
So, what am I looking for?
I was taking couple photos today with my old Sony A6000 with Sigma 30mm f/1.4. Those number might not mean much, but considering bulk and weight of this setup one can imagine that this is not a pocketable camera. Do I need a small camera?
You could argue that if you are going to take camera with you, it doesn't matter if it's big or small, and you might as well take the big one if it takes better pictures. However, taking this camera outside means either having some kind of a bag with you or lugging it on a strap. You can't put it in a pocket. Even jacket pocket.
Convenience
Is it a big deal? It depends. For me, I am now looking for a travel camera, not a studio one, so it makes a huge difference. And brings in some limitations.
Constraints
It's impossible to have the perfect camera, so when choosing a camera you have to find your way within the limits you define. One such limit could be price, another could be size and weight. Having those limitations in place makes your choice much easier. However, we don't want to sacrifice everything and we want the best picture quality possible.
So you want a reasonably priced, small camera that takes great pictures. Why not just use your smartphone?
Usability
Smartphones have become very powerful photographic tools which fit most of the use cases. However, they have some serious limitations like small sensor size (which impacts depth of field) and lack of physical controls.
On the other hand, cameras like Ricoh GR have large sensor and enough buttons and dials to have full control over the camera even one-handed. Is that necessary? It depends. When traveling, with a backpack, walking, etc. it's nice to have one hand free and still have the ability to take pictures with the other. Ofcourse these are not artistic or landscape photographs but rather snapshots or street photos as well.
This brings us to another point: what are you going to use the camera for, what photos are you going to take? Portraits, landscapes, architecture, sports, action, underwater, macro, astro, street... Again, there is no perfect camera that is suitable for all of those at once (and reasonably priced too).
Depending on your style of travel and places you visit you might want to take large, more 'professional' camera with you (for landscapes) or just take a small, pocketable camera instead (street).
In the end
Once I have all those requirements and constraints defined, choosing the right camera should be easy, right?
Too many possibilities
But then new possibilities come along: what about a camera that can shoot great videos as well? Or a Foveon sensor based camera? Maybe a full frame? Or take two cameras, one for movies other for stills. Or just forget about all this and use your phone?
Running in circles...
Sony ZV-1 or phone for videos?
Stablisation or not? (i think it's mandatory for video...)
Panasonic GH5 or GoPro? DJI Osmo Pocket or Insta 360?
Sony a7 or Sony a6300?
Internal microphone or external? Wired or wireless? external or internal recorder? vLog? sLog? LUT?
Spoiled by choice...
