FT v MFT lenses

FT still has got some bulk and weight advantage over what I have collected for my D800. Quite often FT lenses are faster because FF lenses would not find too many customers (weight and price).

I do use the Panny 20 1.7 very often on my E-P1. Yes it can show some substantial CA that the Oly cameras cannot correct but it is very small and other than the CA has got brilliant optics.

Yesterday I played around with a Leica ME in a shop and one of the mysteries surrounding the relatively small and brilliant Leica lenses is that the M series is mirrorless which allows for more effctive lens designs. So the potential is there.

OT:

To answer your question on the thread about no E-7, no I did not use the D800 in LV mode and with CDAF to compare it with the OMD. Frankly, I have not used the CDAF implementation on the D800 at all. Usually with DSLR, it is way beyond that of mirrorless systems and for the most of it I prefer the viewfinder. OVF are not that bad today but still cannot hold a candle to a good OVF.
