Canon Lenses Ef 50mm
different focal lengths but equal fStop values?

Hello, I recently got into photography, but one thing I have not been able to find out: I want to know what is the difference between two lenses of different focal lengths but equal openings? For example, a comparison of Canon EF 85mm f/1.8 and EF 50mm Canon f/1.8 which would be different about the results of photos between these two pictures?

The focal length describes the angle of a few. = 46 ° 50 mm coverage of 85 mm = 28 ° 30 'coverage. The longer the lens the narrower the viewing angle opening gives the ratio of the aperture wide to the focal length. f / stop = focal length / aperture diameter. Opening of the lenses are usually adjustable to at least f/16. The smaller the aperture, the greater the depth of field for its f/1.8 lens at f/1.8 would have very little depth of field and how you stopped the lens down at f / 8 and then f/22, depth of field will increase with the opening becoming smaller

Canon EF 50mm f/1.8 II Lens and 18-55mm IS Lens?

What should I buy for a Canon EOS 450D body, as my first goal? I am a little skeptical and 50 mm has no zoom and is quite old. I like photographing a wide range of topics, people, buildings, landscapes, etc., what purpose would be appropriate? Thank you very much.

Get the kit lens (18-55 mm). 50mm lens f 1.8 (cheap, too), will make a good portrait lens for you and you add that $ 100 for. You can get it now or later, after they have mastered their skills with the kit lens (which will most useful because it can go "off").
