Hiya, got myself a good condition (50K Count) Oly E-M1 mk1 with the batt pack fitted, and a Oly 75-300 mft mk2 in mint condition, sold my nikon gear to fund it as I wanted something lighter due to health.
Cant wait to try it out.
You'll have fun and I'm getting that way myself regarding the weight with the 7Dmkll and 100-400mkll combo. Finding it much more pleasurable walking around with a M4/3. Trouble is, my eyesight is failing fast (cataracts) and I'm struggling with manual focusing with the viewfinder on the EM-10. I've got lots of long analog zooms and appropriate adapters but only come up with the odd good shot due to the manual focusing and I hate live view.. Do I sell the 7D combo for a long autofocus zoom? Decisions, decisions?
