I am sure it has been asked before on this forum but I could not find the thread...

I am a novice photographer and still have a lot to learn about this field. Today I stopped at local Best Buy and was looking at their mediocre lens collection. A sales associate approached me and asked if he could help.... I asked him what does EFS - stands for on the lens - he told me : "It's just brand name" -----but the lens was by Cannon.... I asked him what the letters meant - then he replied "I have no idea. That's how they label lenses".....

mmm ok....sounded like he had no idea what he was talking about.

My question is...is there a guide somewhere on the Internet where you can view ALL lenses available (Sigma, Cannon) and samples of pictures next to them?

I visited Cannon's website and looked at lenses but many are lacking images like what you could achieve with some particular lens.

Also, what are short lenses and long ones? Some say "use short lens for quick captures" - those are 35mm? Lenses with "L" on them meaning long capture?

Any help would be greatly appreciated.

EF = Electro Focus: Canon's standard lens mount since 1987. All of their DSLRs will accept EF lenses.

EFS - Canon's mount designed for crop sensor cameras only, like the 7D or 60D. An EFS lens will not mount on a full frame camera like the 5D.

L - Luxury. Canon's premium lenses. Expense. They are made in a wide range of focal lengths.

Long lens - Telephoto lens such as a 100mm, 200mm, etc

Short lens - Wide angle lens such as a 35mm, 24mm, 14mm, etc

I don't know if they have every lens, but there are most here - http://www.pbase.com/c​ameras (external link). Click on Canon and scroll down to the lens section and search away.

The s in efs means it is for a crop camera only and will not work on a full frame.

Short lenses would be like 50mm and below, medium around 50-135, long anything over 135mm. These are approx and just my .02.

The L designation on a Canon lens is their top of the line lenses.
