I wanted to do this comparison when I first got my EP5.
I'm wondering how does EP5 performs when it places side by side with the very best setup, say, D800E with 24-70. Let's have a look! Please note that this is a simple and non-scientific test, the finding and test method is solely based on user experience only.
The photo at the top is taken with D800E with 24-70, the bottom is EP5 with 14-42II.
I choose to conduct the test around 6.30pm. The reason being is the Sun still above the horizon, dynamic range is wide, this is consider a tough condition to get decent result. However, a decent camera can only proof it's value in a tough situation (of course, this is only my opinion. There are dozen of ways to rectify the issue, eg. digital blending).
Both cameras are mounted on tripod, using same setting (in this case, 28mm, 1/13s, F8, ISO 200), shooting in RAW and converted via ACR to ensure the similarity.
The only thing i tweaked here is both photos downsized to 1200 at longer end using CS5. However, I realised a problem when I doing conversion to Jpeg, should I use F4 on EP5 in order to archive the same depth of field? Erm...something to explore during next tryout.
There are a few minor differences i noticed but there is only one I found worth mentioning: the dynamic range. With the measurement of my naked eye, D800E is 1-2 stop wider. The clipped highlight at the cloud gives a hint as well as the body of the boat covered in shadow. In terms of sharpness, it is not fair to compare a kit lens with nikon's jewel on the crown, but the EP5 produces very satisfying result with the little and inexpensive kit lens!
I better stop here before I embarrass myself (or I already did? =P)
I'm looking forward to do more testing of this handsome, little camera.
Also, if anybody got any test idea or interested to join me for testing, I welcome with arms open!
Thank you for your patiences and spent your valuable time to read my post
