Can anyone here advise a new DSLR user on some basics of the kit lens for the 5D,i have not had my camera very long having recently upgraded from a digital compact,i am in the process of learning about DSLR cameras,my questions relate to firstly the focal length scale reading from 18-70? i understand 18mm to be max wide angle and 70mm to be full tele zoom,but at 35mm the lens seems to be all the way in,almost to a neutral position,is this a default position for the lens? how does this scale relate to actual distance (cm/meters ect)

My other question relates to the macro reading of 0.38m/1.3ft i am not sure of the exact macro range,my previous compacts listed this in spec usually around 6-8 inches down to about 1 inch.

hope this makes sense to someone out there?

Well, it just happens to be at it's shortest physical length at around 35mm. It doesn't really default to a given focal length (you have to change it with the zoom ring).

Different lenses will have different designs. Most zoom lenses will have their shortest physical length somewhere near the wide angle end, and some lenses don't change their outside physical length at all (all optical elements are moving internal to the lens barrel).

It doesn't. It's just the focal length of the lens, which impacts your angle of view (i.e., how much optical zoom you're using). A shorter focal length lens (measured in millimeters) gives you a wider angle of view (less apparent magnification) and a longer focal length gives you a narrower angle of view (more apparent magnification).

This lens has a shortest focus distance of 0.38meters (1.3 feet).
