Some questions

• If you camera came with two lenses, do you need another?

• Why so many lenses to choose from?• Why such a price range?• Does it really matter?

Quick Answers• Yes, you do need more lenses, that is one

of the beautiful things about having a DSLR.– Since their inception, the interchangeable lens

system was appealing allowing armature photographers to not only expand and grow into lenses, but also to adjust to different shooting situations.

• They offer so many because the BEST for one application isn’t the best for every application.

Why shoot with a 50mm lens?

• So long as you can move, immortal photographers like Henri Cartier-Bresson have never needed anything else.

• A fast 50/1.4 is a far better choice than any zoom for use in low light, and effectively quadruples your ISO, with no increase in noise, compared to any f/2.8 zoom. The 50mm f/1.4 increases your ISO by ten times compared to any f/4.5 zoom, again with no change in noise.
