A few weeks ago I snow shoe'd through the Serena Gundy Park
and took both the Sony NEX 5n with the Sigma 19mm f2.8 and the Leica CL with
the Voigtlander 21mm f4. I decided to bring along my Leica M to NEX adapter and do a
quick test on the to see if I could see
any difference between the two lenses. I reasoned that I should
use f5.6 on both lenses, as it was not the maximum aperture for both lenses,
where performance would be weakest.
Just off centre, where I took these crops, the performance
of both lenses at f5.6 is outstanding, easily out resolving the 16MP Sony
sensor. No difference, from what I can see. A quick check of the outer areas
of the photo also revealed no discernible difference.
Which leaves me with one conclusion, for $100, the Sigma
19mm f2.8 is a damn fine lens.
