Hello, How are you? So, I've been shooting my Olympus E-PL2 for the past month... I've been having fun with it, and due to it's small size and weight, I've been bringing it along more often. As such, my 5D has been collecting some dust on the shelf. This got me thinking about selling my 5D and just use the money I make with the sell to buy some more mu43 gear and totally switch formats... I was thinking I would miss some things from my 5D, but if I'm not shooting it, I might as well sell it... I was not totally convinced, and I still ain't... I did today a very quick and not very scientific test to compare the DOF and Bokeh of the Full Frame 5D with the Micro Four Thirds E-PL2. Both cameras are 12 mpx cameras. I used the Sigma 50mm 1.4 on the 5D and the Panasonic 20mm 1.7 on the Olympus... I know they are not exactly the same focal lengths, but the Sigma is about 46mm and the panasonic is 40mm equivalent, so, pretty close for what I was after... I tried to do the same framing on both cameras... I know that the framing should not be the same, because mu43 is a crop of the FF sensor, so the framing and perspective cannot be the same and all that... But I used the same, because if for example, I want to do a head and shoulders portrait, I will do a head and shoulders portrait with the 5D, if thats the camera I have with me, or the Olympus, if I happen to have it with me. So, I want to compare the same framing with the different setups, because that is how I use them... So, here it goes: First, I'll post both at f1.8. 5D at f1.8: E-PL2 at f1.8: Next are both at f2.8. 5D: E-PL2: Next are both at f4.0. 5D: E-PL2: Finally, both at f5.6. 5D: E-PL2: So, I can say that there are big differences... I will do more test, but I think that the mu43 is more of a complement to a FF DSLR system, than a replacement... I don't think a mu43 can go to where a FF system can go... Of course it depends on your uses and what you look for in an image.... Cheers!
