  You probably mean you can't ZOOM past 50 mm. This sounds like a lens defect.

Nikon Series E lenses were the "kit-lenses" included with manual-focus Nikon bodies way back when. Their quality and sharpness is OK but you would definately benefit by getting manual-focus AI Nikkors for your EM.

A lens should be able to slip on and off without forcing it. The focus ring and aperture settings (and zoom, if applicable) should work smoothly.

When buying a use lens on ebay or anywhere else, make sure there is a return policy. When it arrives, check the above for mechanical defects.
Check the glass carefully. It should be clear with no scratches. Open the aperture to its widest setting and hold it up to a light to look for fungus on the internal glass elements. (A few dust specks are normal and won't affect image quality.)

Make sure there are no screws missing. (This could mean that someone other than an expert had taken it apart and fiddled around with things inside.)

Make sure the lens comes with BOTH lens caps. If a lens case is included in the price,...even better. This means that the previous owner was careful with his or her equipment and took care of it.

  More information about the Nikon EM, including the instruction manual, can be found at At the bottom of that page are links to descriptions/reviews of most (if not all) Nikkor manual focus lenses.

Not sure what you mean by "... can't focus it far enough like 50M or more..." Are you unable to turn the focus ring to the infinity mark? Or are you saying that with the lens focused to infinity it is actually only focused to about 50m (~165 ft)?
