I wonder where these guys come from.

If the problem with the 4/3 sensor is noise because of small sensor  
size how is that solved by using even smaller sensors? The resolution  
of the three sensors are not additive. All they do is to provide more  
accurate color.

Telecentrism is only an issue with wide angle lenses and Nikon has  
been making telecentric WA lenses since the 14/2.8 issued in May  
2000. Virtually every new lens that is WA or zooms into WA range  
since then has been telecentric. So he is misinformed in this area as  
well.
