Which 105/2.8 Micro

[Sergio Lopes]

Hi,

I want to thank (in alphabetical order) to
Kevin S. Mahler,
Larry Kopitnik,
Roland Vink,
Thomas Dall, and
Winston Setiawan,
for sharing their experience and opinion about the Sigma 105/2.8 EX Macro and the 
Nikkor 105/2.8 AIS Micro.
I've concluded that the Nikkor is better mechanically and as a short telephoto.
In macro (small distances) and with small apertures (for increased depth of field) 
it's easy to make a sharp lens, so both are sharp.

Sergio Lopes.
