lens review sites
You might try checking back at Dyxum. Click on the lens name for what you are researching and you will get a description of the lens. At the bottom of that page you will see links to other review sites that have reviewed the lens you are looking at.
I always start with Dyxum because it is so comprehensive. I agree on being skeptical of the user reviews especially when the sample is low. Still, they are good to read through to look for tendencies.
Zeiss taste...Beercan budget!
