About 2013 I bought my first micro 4/3 camera and have added to my lenses ever since. I currently have the new OMD E-M1 Mark ll on pre-order and hope to use it for shooting wildlife. It's been quite awhile since I've used my Canon cameras and I would like to sell off two of the camera bodies , but I'm not sure which way to go. I currently have a: 1D mark lll with a shutter count of about 18000 (according to the seller I bought it from), a 1Ds Mark ll with a shutter count of about 6000 and a 5D classic with an unknown shutter count. A full frame might compliment my micro 4/3 gear well just not sure.
