What doies it mean a fast lens?
It's a lens with a wide max aperture ... generally f/1.0 to f/2.8 is 'fast' (f/4-f/5.6 for super tele's). It's dubbed 'fast' as it maximises shutter speed, which helps freeze fast motion without flashSimonhttp://www.simonstanmore.com..

Thqanks a lot for the clear explanation.Is it generally true that fast lenses are more expensive?..

Generally but not always. 50mm lenses are usually fast but cheap (and very sharp, and a great natural perspective), but a 70-200mm f/2.8 will probably cost more than your cam', and a 600mm f/4 ... Start saving : )Simonhttp://www.simonstanmore.com..

A fast lens will invariably be more expensive than a slow lens of the same focal lens but that is because it will usually have better quality optics and better image quality as well. If you buy independent brand lenses such as Sigma or Tamron though they are reasonably priced for the quality you get..

You may upgrade your camera body in due course but a good quality lens will last you much longer and is an investment for the future, so it's worth spending the extra money on something good.

It refers to their speed of departure. Those are the ones a knowledgeable thief would steel first!!.

Investment is rather too strong. They rarely if ever appreciate in value but they do hold their value well..

Just for the sake of argument, "investment" works for me when describing a good lense, since, though the lense itself will not increase in value, the photos it produces will be more valuable in quality..

...or is that too much of a stretch? .
