# Specific Suggestion: [What do all those cryptic number and letter codes in a lens name mean?](https://photo.stackexchange.com/q/496/11924) I suggest this question be broken up into individual questions **per manufacturer**, and set up as a bunch of FAQs. So it would look something like: * What do the letters and numbers mean in the names of Nikon lenses? * What do the letters and numbers mean in the names of Canon lenses? * What do the letters and numbers mean in the names of Sony lenses? * What do the letters and numbers mean in the names of Pentax lenses? * etc. ... As well as another few FAQs to point to those Q&As, by feature: * How are lenses for crop-sensor bodies identified? * How are lenses with image stabilization identified? * How are lenses with special optical features identified?
