   40MP is More than enough. Hope this system will do well in Landscaping as well. The more & more I think that medium Format isn’t the right tool for landscape photography, as a smaller lens + smaller sensor provides bigger & crispier Depth of Field.
   Medium format would be nice for greater Dynamic range & MP though.

     nothing beats large format camera for landscapes.
     Think about it that sharpness is not parameter of sensor / film size but apperture and hyperfocal distance. Each lens size will show on any film size exact same amount of sharpness, you just see wider (or can be more far away therefor extend the area of acceptable sharpness) with large format cameras. Yet you get more megapixels as bonus.
     Reason why you think small sensor cameras have less shallow focus area is because you compare for example 14mm on 4/3 system with 28mm on FX system. Put 14mm on FX, step back to let it cover same area and you get much more covered with same focus depth.
     Also landscapes nobody shoots at f2.8, you usually are picky about weather condition and shoot at f16 and more and slow speeds on tripod to get sharpest images.

     Any camera even a monster 8×10 has lots of depth of field if shot at F32 or something similar, and thats what most landscapes are shot at.

       When I shoot at F22 on my Medium Format body, I have difraction & the forground or backound is still blurred even when focusing right on the forground, please tell me how to get the whole picture sharp ???!

         Well in the case of landscapes i was refering more to view camerand not MF. But none the less a MF lets say at F5 – 10 is still razor sharp if used right. There is no need to shoot landscapes at F2.8.

   Great….

   Now I have to figure how to come up with 6500 + lens money. Assuming the pricing reports are still accurate.

   that 6500 price is a miscalculation apparently

   I think 9mp is enough for all digital cameras for now. 40MP is bit too early for now. However, we will see 40MP compact digital cameras near in the future.

     Is this a coment copied-and-pasted from a 2004 internet debate?
     No, 9 mp is not enough for a photographer wanting big and still good magnifications…

       9MPx would be ridiculous on Medium Format camera.
       Come on… we don’t want a single pixel to be in the size of compact camera sensor.
       The huge advantage of MF digital cameras is their resolution – that’s what allows you to make a pictures for billboards or trains – and that’s what advert-agencies want from photographers more than often.
       Believe me or not – it’ll be easier to earn for life with 40MPx MF than with 9MPx MF even if it’d make uber-quality photos.

         We can imagine a 9 mp MF camera with iso as high as … emh… can’t spell the numbers… milions?

         I think the lack of the AA filter is also one of the biggest advantages to MF digital.

           but also an issue with CA, which is nonsense to correct in postprod (it will affect original sharpness). The best way to go is with a super Thin AA Filter.
