Canon EOS M High ISO Testing


Today I received the Canon Adapter for the Canon EOS M and wanted to do a quick review. Canon EOS M Mount Adapter and wanted to do some testing of the Canon EOS M high ISO in low light conditions. I just happened to have the Canon 70-200 IS 2.8 next to me. Canon EF 70-200mm f/2.8L IS II USM Telephoto Zoom Lens for Canon SLR Cameras I know this is an unconventional way to test and I will doing much more extensive testing on this camera with the non adapter lens as well as against the NEX-7 (which I own as well.) Sony NEX-7 24.3 MP Compact Interchangeable Lens Camera with 18-55mm Lens.

The camera of course looks awkward with the huge lens on the little camera but one thing that really any professional will tell you is that the camera is a tool… any camera could take great pictures to an extent. It’s more about the photographers skill and ability to get the right exposure that is the key. I really want to dig into this camera as I have just read so many negative things about about it to see if it is just truly people have tested and the camera isn’t of quality or people just had some expectation of Canon and in their minds it didn’t reach that standard. Even though they may have never actually taken a picture with this camera.

Overall, my initial impression was pretty positive about two things. The Adapter worked really well with the 70-200… or should I say as expected for Canon Equipment. The surprise to me was the performance of the ISO in lower light considerations. You could see by the samples below that my 6400 ISO picture is pretty useable.

Conditions for this test were:

1.) Adapter showed up from Amazon and put right on the camera with no reading or setup

2.) My couch in my office with lap light pointed up and some natural window light over my sholder

3.) Canon EOS M in AV mode with the 70-200 II USM f2.8

4.) Model: Juliette my Caviler King Charles Spaniel which is one of the best breeds in the world.

5.) Out of camera uploaded to Flickr via Lightroom with no edits

You have a view of 100 ISO up to 128,000 ISO… Take a look and let me know what you think: (Click on any picture for a larger view)

This is a 100 ISO version and yes it is not as sharp but I didn’t have great light. I will be taking some more high light version to show the lower ISO. I was really focused on the higher.

    Nice post. I learn something new and challenging on blogs I stumbleupon everyday.
    It will always be interesting to read through articles from other
