Canon Ef S Lenses List
A question about lenses?
- Http: / / www.usa.canon.com/consumer/controller?act=ProductCatIndexAct&fcategoryid=140 – The http://www.nikonusa.com/Find-Your-Nikon/Camera-Lenses/index.page each of these sites, you will see a list of objectives for Nikon and Canon DSLR cameras. Let's see an example, AF Nikkor 20mm f/2.8D. – What does the f / stop concern numbers, not the open range determined by the camera? Or is it? – And the "D", and the lenses of some "ED" instead? Let's see another example in the Canon site: an EF-S 10mm-22mm f/3.5-f/4.5 USM – But why does this have two f / stop numbesr? – What does it mean for USM? Thanks Lars, I understand basically opening (like what you said about using the shutter opening and together, etc.), but my question was about the lenses.
f / # which appears the list is the maximum. So a 50mm f/1.8 has a maximum aperture of f/1.8. The smallest is about f/22ish. ED reduces chromatic aberration (edge color). color band is … errr … because the light is of different wavelengths, when passing through the lens, the colors each curve a different amount so that (the colors) do not focus on the same site. The ED element corrects this. The two given f / stop numbers are the maximum f / limiter range at the given focal length. So in 10 mm, the maximum is f/3.5. At 22 mm the maximum is 4.5. The minima also change. USM is … umm … basically a focusing motor built into the lens. Not require a screw drive (where the engine drives the camera lens), so basically a camera without a lens screw can be used (such as D40/60). They are also generally quieter and faster approach.
