I'm thinking of upgrading to a DSLR camaera and I was wondering if someone could help me with something.
When looking for lenses, I often notice that on the description of certain lenses it says, for example, aperture 2.8.
Does that mean that this lens has only one stop which is 2.8 or does have it a range of stops and 2.8 is the widest it will open?
As you can tell, I'n new when it comes to lenses, as I've only been shooting with DV cameras with built on lenses.
Help much appreciated.
