New things keep coming up- For instance we are learning that the next lens for Sony NEX FF will be a Zeiss 35/2.8.

So, that gathers 500% less light than a F1.4 lens. Are you saying the sensor is 500% more efficient? Must be that Sony fairy dust.

Just as predicted: no need for a fast lens if you have a fast sensor.

So, if the kit lens for a Canon FF is F4, does that mean Canon sensor are better than Sonys because the camera comes with a slower lens? Don't you think that's pretty silly? And the Sony kit lens should tell us what we need for our circumstances?

Not covered also de dematerialization of the lenses. Liquid adaptive lenses (Canon Patent) or light conversion directly by sensors with no need of lenses.

It's always good to refer to non-existent technology in an argument. Do you know how many patents Canon has that never came to market?

In fact all the progress appears to be sensor led. So how to think that this won't have consequences on traditional lenses? In fact even SW corrected lenses are dematerialized by processing.

So, in the film days, did higher speed film allow slower lenses? Did we all throw our fast glass away because someone came out with ASA 800?

Another important consequence is that lenses don't hold their value anymore, because they are superseded by improved ones. I.e., by linear motors that actually cost less to produce.

My 20 year old lens performs better than anything dreamed of outside a Canon or Nikon system, and retains value just fine.

Ring ultrasonic motors have never been beaten. Linear motors are cheap imitations for the mass market designed to lower cost.

There's a whole new world there that you pretend to ignore. If you have the sensor horsepower it make perfect sense to reorient your choice of optics.

Sensors don't have horsepower. All sensors are basically the same to within 20-40%. There is no fairy dust you can sprinkle on a tiny lens and make it work like a larger one.
