Polaris Auto Zoom Lens 1:3.5 f = 80mm ~ 210mm E. P.

The 80-210mm lens is a multi-purpose lens.  This is one of the most versatile lenses - good for distant subjects and excellent for close-ups, sporting events, landscapes and portraits.  You can shoot from as close as 6 feet or from long distances, under just about any average light conditions.  This lens can take the place of three or four fixed-focal length lenses, making it an economical lens to own.  With a little bit of creativity, this lens can produce images possible only with a zoom lens.

Zoom Action & Close-Up

	This lens features an automatic diaphram.  The focus can be adjusted separately from the zooming action.  Just turn the focus ring to focus, and the zoom ring to zoom.
The calibration on the lens barrel shows the focal length for any zooming position, (but this need not be consulted because optimum picture composition and area can be easily determined through the viewfinder).
Once focused, the zoom lens maintains the focus setting even while zooming.  It is a good practice to focus at the maximum focal length, i.e. with the largest possible image, and then zoom back to the desired field of view.  This ensures maximum focus accuracy.
