EM-5 vs EOS-M

EM-5 vs EOS-M

This post is about a quick comparison between my Olympus OM-D EM-5 (that is a mouthful, so I’ll shorten it to EM-5) and the Canon EOS-M.  Sorry, this isn’t an in-depth scientific test, but more of a seat of the pants real world comparison.

The EM-5 is mine and the EOS-M belongs to my son, Steven.  He got a great deal on his gently used EOS-M (with a couple of lenses), and was kind enough to bring it down during our motorhome vacation at the Chula Vista RV Resort.

My first impression of the EOS-M was from what I had read on-line.  And unfortunately the reviews weren’t very good.  But once I actually got to touch and feel one, I was pleasantly surprised.  The size was perfect (small, but not too small), and it had a nice heft to it.  There isn’t an electronic viewfinder (EVF), and the screen is fixed.  The EOS-M also has a touch screen. The other thing I noticed is that there aren’t many external controls.

The EM-5 on the other hand had glowing reviews since it was first introduced.  I knew I had to have one, and have written about it in previous posts.  To summarize, it’s just the right size (for me), has a movable view screen, and a great EVF.  One more plus is the amount of external controls.  The EM-5 has a touch screen, but I don’t use it and have turned it off.

So, how exactly did we go about comparing these two great little mirrorless cameras?  We put each camera on a tripod, and set them to manual.  Then the aperture was set to f/16 and the shutter speed set to 30 seconds.  Finally, each camera had the ISO to 200.  Here are the results:

Other than converting from RAW and resizing, each image has had no post processing applied.

Let’s look a little closer.  I zoomed in to 100 percent on each image. Then I selected a small section and cropped it.  This is what they look like:

Now, the question is – which one is better?  Personally I think they are both great, and there is no clear winner in my opinion. Unprocessed, there is some noise, but nothing that some noise reducing software can’t handle. Will these cameras win any low light contests against full frame DSLR’s? No, most likely not. But that’s ok because they have other advantages like size, speed, and ease of use.

I could have processed these images, cleaned them up, sharpened them and applied some other tweaks and adjustments., but I didn’t want to do that.  I wanted to share what each camera can do right out of the box.  Each image is presented honestly so you can judge for yourself.

Either one of these cameras would be a fine choice if you are in the market.  It really boils down to personal preference.  The best thing to do if you’re interested, would be to get your hands on them and see which one feels the best in your hands.

That’s it for now.  Until next time – Happy Shooting!
