Hi guys,
I have this question that's been bothering me for a while, concerning the Aperture property of a lens. I presently own a 35-70mm 5.6 and a 80-300mm 5.6.
Now when i take pictures, prior to any photoshop modifs, using only 'AF' settings (complete automatic), i feel that the shots are less 'bright' or colourful then 'other' cameras.
My question is simple, does a 2.8 aperture lens gives better 'colours' and 'lighting' quality then a 5.6, while using the same aperture?
If that's the case, i'm considering just getting rid of my 5.6s and concentrate on 2.8 lens...
Thanks for your help!

An f/2.8 (or faster) lens does not by definition give better contrast & saturation at a given aperture. That said, you will find that many fast lenses DO in fact give better saturation & contrast, simply because they are typically better designs, since cost is less of a concern for "fast glass."

You try changing the profile the camera uses? I find Landscape gives a touch more saturation. The White Wedding "Curve" gives a bit more brightness in the midtones. But, you have to load that one.

| Does anybody have a quick essay or some information to help me understand the basics of lenses? For example, what is 'fast glass'? |

This page will tell you everything you need to know about exposure and lighting: //www.fredparker.com/ultexp1.htm
This page will tell you quite a bit about the optics of lenses (but not a lot about how it applies to photography): //en.wikipedia.org/wiki/Lens_%28optics%29 |

A lens with a wide aperture. So called because wider apertures mean the shutter can be shorter in the length (faster) to create a properly exposed image.
Fast lenses can be used for lots of things, for instance: portraiture (because wide apertures also give nice background blur), or sports (where fast shutters are used to help freeze the action).

Wide aperture = f/small number (f.inst. 2.8 or lower), Small aperture = f/large number.
Wide aperture means that the iris of the lens is wide open and therby lets in more light than when the iris is very small in the same amount of time.
When talking about fast lenses it means that you can open the iris very much (wide aperture) and therby it needs shorter exposure (short opening time, fast shutter) compared to lenses where you can not open the iris as much.
This has very litle to do with color and lightning quality but as kirbic mentioned then "faster" lenses are generally of better design and quality (and costs more). |
