Didger - surely an MF DSLR isn't really a true competitor to a 1Ds ? They are very different beasts. The ZD is quite primitive in terms of functionality compared to the 1Ds, and you can forget long lenses, stabilisers, and fast frame rates. I think you're a pure landscape guy - but if you're at all into wildlife, or indeed long lens landscape shots, then the ZD isn't going to replace your 1Ds... is it ?
