Is The Canon EOS 90D Full Frame?

No, the Canon EOS 90D is not a full-frame camera. It never was and never will be. 

So What Type Of Camera Is The Canon 90D?

Yep you guessed it, since it is not a full-frame camera there’s only one other thing it could be.

The Canon EOS 90D is an APS-C camera so it is a ‘crop-sensor’ camera. And since it is a Canon crop sensor camera, the sensor size is (22.3 mm  x 14.9 mm). 

This is basically the same sensor size as other APS-C Canon cameras like the Canon EOS 60D or Canon EOS 70D.

How Does It Compare To A Full Frame Camera?

So we know that the Canon EOS 90D is an APS-C camera with a sensor size of (22.3mm X 14.9mm), but how is this different to a full-frame camera? 

Well, Canon full-frame cameras typically have a sensor size of 36mm x 24mm. 

This actually makes a full-frame Canon sensor about 1.6x larger than a Canon APS-C sensor. 

This is what affects the crop factor that you end up with on APS-C cameras.

What Is The Crop Factor On The Canon EOS 90D?

The crop factor for the Canon EOS 90D is 1.6x. 

So if you want to find the full-frame equivalent focal length of a lens, you need to multiply it by 1.6x. 

Let’s have a look at how a 75mm lens will look on the Canon EOS 90D:

  • Focal length of lens = 75mm
  • Crop factor = 1.6x
  • Full-frame equivalent focal length = 1.6 x 75mm = 120mm

Looking at this example, you can see that when you are using a 75mm EF or EF-S lens on the Canon 90D the actual full-frame equivalent focal length ends up being 120mm. 

Do remember though that you can’t just use any lens on the Canon EOS 90D and it depends on what type of camera it is. 

Is The Canon EOS 90D DSLR Or Mirrorless?

If you already have Canon EF or EF-S lenses then you’ll be happy to know that the Canon EOS 90D is a DSLR and not a mirrorless camera. 

Lenses Compatible With The Canon EOS 90D

Since the Canon 90D is a Canon DSLR, the only lenses that are compatible by default are Canon EF or EF-S lenses. Any EF or EF-S lens will fit on the Canon EOS 90D. 

Mirrorless Canon lenses use a different type of lens mount and therefore they have different types of lenses. 

So don’t go trying to stick a mirrorless Canon lens on the Canon EOS 90D. It won’t fit.
