I have a solution.
I have a good friend who is interested in photography. I will be lending him my Oly EP-3 to play with to see if he enjoys it and, if he does, will offer to sell him my m4/3 kit at the trade-in price offered. Until he decides I will keep my m4/3 as a walkaround. If he thinks not, I'll sell the m4/3 kit them along at the A7II body.
I already bought the Sony A7 R II and a Batis 85 to go with the A7 II, Zaiss 55 and Sony 24-70 I already have. Should be delivered tomorrow.
Complex dance but it will work, I think.
