[Leica] Up-resolution with PS Enhance and with Gigapixel

[Frank Filippone]

I am of a similar mind to Howard. Ultimately, a huge pixel count sensor
combined with a single really first class lens, is all you need. You want
telephoto?  Crop. You want wide angle? Use the full frame.
I am using the Sony A7rii now. 42 or so Mp. It is not yet enough to do what
I want  It would need to be closer to 200mp. That would effectively allows
your 28mm or 24mm or 21mm lens to be crop-zoomed to 50mm or so with 40-50
mp. Crop to 100mm effectively and you still have a resolution of 10-12mp.
Still good for 8x10 prints.
Range of 2:1 is a pretty good travel zoom lens. 4:1 is even better.
The real advantage other than only buying one lens is that you are carrying
only 1 lens. Lighter weight and smaller bulk. Good things.
Where does Leica fit?  The lens must be high resolution. A Leica specialty.

Be patient. Technology will catch up with market wants   Maybe it is 3-5
years away?
