Like your feedback. Distance Measurement

[raycsk]

Hi All,

Extracted from an article
"The purpose of a distance meter in photography is to enable photographers to focus their lenses upon objects without measuring the intervening space with a scale or tape. Focusing is necessary on account of the variation in distance between the lens and image in proportion to the distance from lens to object. Critical focusing is most necessary when the diameter of the lens opening is large compared to its focal length. In general, any lens operated near its maximum speed needs to be accurately focused for near objects."

Like to find out if anyone here (especially users of 35mm and rangefinders) would use such a device to help you take better pics.

Appreciate your comments and feedbacks.

no experience, but is it still necessary with current advancement in focusing system (camera wise)?

Yeah you're right. But what about those folks using manual lens or shooting videos/movies?

Old enough lenses (circa 1990s ) should still have a distance scale on the lens. Why not just focus and then have a look at it?
