I'm needing to start serious planing for a second Canon dSLR and move my 5D to a back up role. Have there been any detailed comparisons between the 5DMkII and the 1DsMkIII? I had planed on a 5DII but it seems to have problems. A clean used 1DsMkIII would give my a weather sealed pro-grade camera which I can look to many years of use out of. Canon's are my bread and butter cameras which I use when there's money on the table.
So, those who have used both what are your opinions? Any serious comparisons out there (no KR please).
