pixelpeeper.com where users can check full-size
photos (of other flickr users) from given lenses or cameras at
specific settings (apertures, focal lengths). The purpose of the group
is to share your opinions about the technical aspect of lenses and
cameras. If you want to post a photo to the pool: - photos must
be at least 7MP in size - YOU MUST tag your image, specifying used
lens (for SLR cameras only; for compacts, you don't need any tags),
like this (don't forget the quotations to prevent from splitting into
multiple tags): "Nikon 18-200mm f/3.5-5.6" for zooms
"Tokina 12-24mm f/4" for constant aperture zooms "Canon
50mm f/1.8" for primes Don't add anything other than the brand
name (Canon, Nikon, Tokina, Sigma, Tamron etc.), focal lengths and max
apertures. e.g. don't add: nikkor, ef-s, is, dx etc. Note: Since
many of you also post to brand-specific lens groups, you can now use
alternative tags as well -- these are the same tags as the ones used
in these groups. Here's a list of groups whose tags are also
allowed: SLR mounts: Canon EF & EF-S -
