I’ve got an itch for a full frame Canon body, mainly for landscape / urban architecture, currently I’ve got a 7d MkIX which I use for wildlife. The big question is what body do I look at? Theoretically finance isn’t an issue (although justifying it to she who must be obeyed might be!) I own a Canon 10-22mm which I love using and if I went FF I might exchange for a Sigma 12-24mm. I had considered a 1d Mkiv as they are pretty cheap - but the 1.3x sensor takes me back to where I am with a 10-22mm. So any suggestions? My current thoughts are between a 5d mkiii or a mkiv.
