Lens 102

So why all the fuss about fast and slow lens?

Fast lens enable you to take pictures in low light without having to reduce your shutter speed. f/1.4 at 1/60 will be much brighter than f/2 at 1/60 of a second.

Again, refer to the chart from the previous post…

It is important to remember that you might not need speed!

If all you ever photograph is landscape, it is highly unlikely that you will need a fast lens; why? Because depth of field (DoF) will dictate a much smaller aperture (more later).

Also, you can offset the benefits of a larger aperture by using a tripod and slower shutter speed, you could change the ISO, or you could simply use a flash.

When starting out, buy what you need for lens.

Thanks for reading, keep on shooting, and, as always I look forward to your continued support.
