Let there be light
Lenses are needed to bring the light to the camera. While a lot of people consider the cost of cameras, they do not realize that in the long run, it will be the money you pay for the lenses that will dominate the cost.
Quality of lenses
- Focal length expressed in mm. The larger this number the narrower the view, which makes it look like you have magnified things (not entirely correct). For this reason it is also sometimes expressed as field of view in degrees.
- Aperture expressed as an f number such as f/5.6, it determines basically how much light gets to the camera. The smaller the number, the more light gets in (the more open is the lens) and it is said that the lens is faster.
- Minimum focus distance, how close you can come to the object and still be able to focus. Usually this correlated well with the focal length (longer lenses also have a larger minimum focus distance), but lenses can be designed to allow you to come closer see macros.
- Weight should be one of the main issues when considering a lens.
- Then there are further issues like Sharpness, Bokeh, Distortion, Chromatic Aberration that you can hear about.

These pages are for Amateur Photographers and not really for seasoned photographers and professionals. I have no affiliation or commercial interest with any brand/make. I write from my own experience. I ended up using mainly Nikon, so I am more familiar with this brand than others. See price for notes on pricing as well as photography related links.
