so if my camera says 28-280mm, what exactly does that translate to?
.028 - .280 meters.
this is a really dumb question. expect more dumb answers.
it doesn't work like that. both of these pictures were taken at 200mm, which do you think was closer?
It's simply the focal length of the lens.
well so it's a measure of how far it'll push in in relation to where the camera is right?
well how bout you educate me instead of acting like an asshat?
It refers to the focal length. Not all lenses change in length as you zoom in and out. Doesn't have much to do with the physical length of the lens. Some 300mm lenses are longer than others. The 35L I believe is physically longer than the 50L.
Those numbers don't specifically translate to anything in regards to distance.
The focal length is simply the strength of magnification of the lens, and the measurement is the distance from the middle of the lens to the focal point.
It has nothing to do with actual subject distance.
i'm guessing your referring to a point and shoot with its 3x or 4x or 12x etc zoom. they don't directly correlate, but you can use google to find the approx range of the point and shoot you are used to using. then compare that to the range of the lenses you are looking at. remember to figure in a crop if you are using a crop dslr.
thank you for all your very useful replies, unlike someone else's in particular which was completely useless. that article @ dpreview was enormously helpful. i understand now. thanks!
