I am taking on board your comments and many others, my aspiration this year is to really make some quality images, be they wildlife, landscape or whatever I can get around to shooting. I know I am still some way off getting repeatedly good results and I think I know what to work on now and where the limiting factors are, (me for 1). The thought of FF still appeals and I will re-think it after Christmas.
Thanks for your comments. ;-)
Sam, what's not clear to me from your previous posts are your 'needs'.
Do you need the thinner DOF or low light advantages of FF (with appropriate lenses of course) ?
I can't recall you posting any photos that suggested that was your style or interest.
It's all very well changing systems but will it actually improve your photographs.
I think it's wise to at Louis Dobson's approach where he carefully evaluates his needs and then buys the most suitable equipment.
Also I recall him saying that he prints up to 60 X 40 and finds M43 good enough for that.
I get the impression that you are being driven by gear lust rather than need and that can be an expensive road to go down.
Personally for me the old 12mp sensor was suitable apart from DR and if that had sufficient DR I would have been looking to upgrade my cameras every five years at most. In fact when Olympus comes out with a larger four thirds lens PDAF compatible camera with the current sensor, that and the OM-D will be sufficient for a long time barring any revolutionary advances
