When looking for new auto focus zoom leses what are some things that I should be looking for. I'm more intrested to know what the F4.7-5.6 refers to when I see this in regards to the lense.
For example, "PENTAX SMC FA ZOOM 80-200MM F4.7-5.6 LENS". How does this affect the lense?
Any info would be appreciated.
