I'm planning some trips soon and thinking about getting another mirrorless and looking at the Canon EOS M200 it looks just about in terms of size and cost.
Folks seem to like that camera, and Canon sells a lot of them. People are predicting the demise of the M system, but I’ve read that they make up 30% of Canon’s camera sales, and so the company says continued production is very likely.
My question though is are the photos a large enough improvement over a good phone camera to justify it?
If you get it with a zoom lens with a long enough range, then it can do things that most smartphones cannot, as most cannot zoom, and can only do image-quality harming crops.
Furthermore, with a suitably fast lens, it can take much better quality images in dim lighting. “Night mode”, found in some higher-end smartphones, takes multiple exposures and blends them together, narrowing the gap, but getting it right in one shot usually is better, especially if the camera or subject moves between shots. But some dedicated cameras have this feature as well.
What I do if I’m traveling lightly with my camera is to take two lenses: a lightweight zoom for daytime, and a fast prime for dim interiors and night. My big, heavy lenses are reserved for special occasions or locations that need them, but I don’t carry them around with me.
Second question: is there an alternative that is similar size that does much better in terms of photo quality?
Two common factors in technical image quality are signal-to-noise ratio (SNR) and the ability to resolve fine details crisply.
Larger sensors collect more total light at any given exposure, and so have a larger SNR, but there comes a point where more SNR doesn’t appreciably improve things unless you’re making huge prints. So in full sunlight, even small sensors can perform well enough. 1”-type or smaller sensors can be found in very compact cameras that perform very well in full sunlight.
Larger sensor cameras like the M200 perform better is in dim lighting.
Being able to resolve finer details requires more megapixels and a higher quality lens, but again this is subject to the law of diminishing returns, and will only be appreciated in large prints taken with good technique. Small sensor cameras tend to rely heavily on noise reduction, which harms resolution in dim lighting.
