The 5D mk II was very successful for landscape work, but it was mostly just a re-hash of the one year old 1Ds mk III sensor in a low end body (nothing wrong with that - I've got a 5D mk II and its great). Nikon broke the mould this time round by featuring a high MP sensor first in a non flagship model, but that doesn't mean Canon have to follow them down that route.Some of the most dramatic lighting for outdoor shots such as landscapes can be when the sunlight momentarily breaks through a storm. If you're doing that, weatherproof gear is nice to have as a backup if the umbrella breaks...
The sensor is probably the single most expensive component in an SLR - why would what is likely to be the most expensive production Canon sensor at the time of release be put in a budget body? It'd still be an expensive camera, aimed at pros. Stuff like a minimal shutter lag, minimal viewfinder blackout and fast x sync (on full frame) are still exclusive to the 1 series, as is the rugged build to cope with years of use and abuse by owners who sees it as simply a tool rather than a treasured once in a lifetime investment - so why not put it in a 1 series body?
1.) I think professionals have already demonstrated that expensive cameras are not going to fly. But, Canon's main customers, non-professionals, will shut this camera down if it arrives with a 1D series body and price.
2.) Sensors do not add the expense the gullible public believes they do. The largest expense in a !D serties camera is marketing cachet.
3.) I think the vast majority of professionals shooting landscape in the backcountry (as opposed to overlooks
with the rest of the tourists) will want a small light body like the 5D2 which they adopted in droves.
4.) If someone is put firing away with a 50 MP sensor at landscapes and needs zero shutter lag. he/she may have purchased the wrong camera.
Not all subjects requiring high MP are stationary like landscapes and product photography - any studio work with moving objects such as models does benefit from short shutter lag and minimal viewfinder blackout, and a fast flash sync speed is a huge help in countless situations.
SO TRUE!!! I just do not get it when people mention landscape along with high MP.....
None of these features preclude a lighter, small body. You fellows presume these features must go hand in hand with a boat anchor and ridiculous pricing. This just doesn't have to be true. Maybe that's why a 3D body keeps being mentioned in relation to high resolution. I really think there's something to be said for the idea that folks have an emotional need to own a large camera disregarding the heritage of the 35mm format being a smaller, lighter camera.
