Canon EOS M10 Mirrorless Camera | A wicked Little Piece of Kit

Now this here Canon EOS M10 Mirrorless Camera is a wicked little piece of gear because it has no mirror. That makes it a small handful that packs a photographic punch way above it’s size – assuming you don’t drop it in a pool first.

It’s ‘mirrorless’ and has an APS-C (Advanced Photo System type-Classic ) photo capture sensor which is the same size (or a tad smaller but in some cases a tab bigger) than the regular sensors in DSLR (Digital Single Lens Reflex cameras – that’s the regular size cameras with interchangeable lenses). Do try to keep up with the acronyms people!

See FYI, megapixels is a minor part of the overall picture quality. Ease and economy of manufacture means they can stuff sensors with megapixels and quote you such and such million megapixels.

Megapixels also rolls off the tongue and given it has at least four syllables and the word Canon EOS M10 Mirrorless Camera Sensor Size‘mega’ (which everyone is rather  impressed with), and then you can have fifteen million of the little buggers – and fifteen million of anything HAS to be a good thing you drop your hard earned cash and walk off with your new camera quoting megapixallage to everyone with buckets of authority just before eyes glaze over.

The fact that megapixels sounds so good – 20 million pegamixels – is not lost not lost on the frightfully clever people in Canon (and everyone else’s’) marketing who adopted the term as their main selling point for cameras.

I dare you to find a single camera on display that tells you sensor size – you won’t. You always have to dig it out. And dig I mean dig. Even the specs on the manufacturer’s websites seem to shirk the subject the way your mum might avoid questions about that embarrassing cousin.

Most sales people in shops don’t even know what you’re talking about when you ask about the sensor – but they do know, and rattle off with much glee and knowledgeableness the millions of megapixels you get free with every camera.

A Bit More About Sensor Sizes

Let’s explain sensors in very simple terms for your benefit. Image capture sensors (the bit where the picture as actually made [what used to be called film]) in cameras is composed of millions of light sensitive points called photosites (I mean even spellcheck ain’t never heard of this stuff!) which capture the light entering through the lens and translate it into the image you see.

Phone cameras tend to have sensors the size of the two smallest frames in the picture (the full grey frame is 35 mm, as we all know).

Compact cameras move up a little but are still the max size as shown in blue (or perhaps first green) sensor sizes.

And Sensor Size in the Canon M10?

This here little Canon M10 has a sensor that’s one tenth of a mil smaller than the APS-C 23.60 x 15.60 mm (that’s top row second right in the picture below for all you tiresome lot who simply aren’t making an effort. I mean really!)

SO it stands to reason that the larger sensor and larger aperture (the opening on the front that allows light into the camera) have a higher dynamic range – they will capture more light and therefore more detail and hence higher resolution.

All this to say gepamixels are a somewhat meaningless measure of image quality and resolution – it’s a marketing term that, being meaningless, doesn’t really mean anything.

The relation between sensor size, dynamic range and something for another day called distortion ratio to is rather eloquently explained below. And since I didn’t get any of it, read what (and how many times) I may, I’ll leave it to the Einsteins among you to figure it out.

One last thing you need to know before your test is that in order to keep devices as slim as possible manufacturers of phone and compact cameras are restricted by the size of the aperture they can use and more critically the distance of the aperture (or lens) from the sensor.

This proximity is the stuff of nightmares for the poor buggers trying to eek out every bit of extra resolution within the space of a few millimeters.

You may call this the microlens geometric extent to photosensor ratio.

It explains why DSLRS are still the size that they are … we all know what DSLR’s are, don’t we?

Canon M10 Mirrorless Cameras, Mind Warps and Brexit

Sit down before getting your head around this here elegant mathematisation of the Canon EOS M10 Mirrorless Camera Sensor Size

Truth be told I don’t think anyone really has their head fully around it all so don’t worry if you don’t get it. Not everyone is like me.

It’s a bit like Brexit.

Except of course Brexit is a bit more complicated than this lot of mind warpity.
