As I continue evaluating the Olympus OM-D E-M1X Micro Four Thirds Camera that Olympus has loaned me for 2 months free of charge (and with no obligation at all to write these reviews) one aspect I will be studying is how usable high ISO images are with this camera.
I have been shooting full-frame digital since I purchased my first full-frame camera back in 2002 with the $8,000 Canon EOS-1Ds, an 11.1 megapixel camera. And simply because of the physical size difference between a full-frame sensor and a four thirds sensor, full-frame sensors by and large have less noise at higher ISO’s and thus are better in lower light situations.
But how big of a difference is the noise in higher ISO’s?
If you believe everything you read in internet forums, people are saying anything over ISO 800 is basically non-usable with four thirds cameras. This was concerning because I am often shooting ISO 800 or higher with my Sony a7R3, particularly with wildlife, and if this Olympus camera couldn’t handle higher ISO’s I would lose pretty much all interest in the Olympus system.
So I went out to a local zoo the other day to get some test shots at higher ISO’s. And this writeup is about my reflections from that day.
