In conjunction with other Canon-related groups on Flickr, the Canon EOS 5D group has accepted a standard for tagging photographs with the lens you used. We kindly ask all members to tag their photographs using this standard. While our rules do not require you to tag your photos, we still encourage you to do so.
To make things easy we would like lens tags to use the following standard. Tags should be consistent with EXACTLY how the lens manufacturer specifies your lens on their web page. This helps to avoid confusion. For example, Sigma produced two versions of the Sigma 8mm f/4.0 lens. So both lengs tags would be entered as such:
"sigma 8mm f/4.0 ex" or sigma8mmf40ex
"sigma 8mm f/4.0 ex dg" or sigma8mmf40exdg
Here is another example. If you go to the Canon web site, a lens is called something like:
Canon EF 50mm f/1.8 II
...which is not to confuse it with the Canon EF 50mm f/1.8, which is a completely different lens. Another example is the Canon EF 100mm f/2.8 Macro, which is available as a USM version and as a non-USM version.
When you add the tag "canon ef 50mm f/1.8 ii"; the Flickr web site files it as canonef50mmf18ii (removing punctuation such as /, -, . etc.). So you can enter the tag either way. You are also encouraged to create a Notepad or .txt file with all of your lens tags. This makes it very easy and quick to cut and paste lens tags as you upload new images.
If everyone adds lens tags to their photographs all Flickr members can enjoy the ability to search for photographs using that tag. It will help everyone make decisions before they purchase a new lens and it might help novice photographs decide what lens works best in a particular situation.
