Subject: [Leica] IMG: 250 Telyt and Sharpness

I have looked at the images from the last couple of days, to see if I can 
detect a difference in sharpness with the Telyt at three apertures, f/4.0, 
f/6.3, and f/8.0.  Admittedly, the subjects change from time to time, so 
that may have an influence.  I will provide links below, in case anyone 
would like to provide an input.

A Cardinal at f/8.0:

A White-Breasted Nuthatch at f/8.0:

I must admit that, although focusing is easiest at f/4.0, I like the f/8.0 
images best.

Comments and critiques are welcomed, as usual.
