AF Nikkor 50mm f/1.8D
"Hot spot" aberrations at apertures lower than f/11 - please, please, do not purchase this lens. Research it first.
When a customer purchases a lens from Nikon, it is generally assumed that the product will meet the highest standards of quality and dependability.
This is why I was so surprised to discover a "purple spot", or "pale blue dot" visible at lower apertures on the AF Nikkor 50 mm 1.8 D. After a great deal of trial and error, trouble shooting, and wasted money cleaning the thing, I learned, to the best of my knowledge, the purple spot is presumably caused by light bouncing off the sensor, back on the rear element lens, and back on the sensor (no, this is not glare, it is not a lens flare, or dirty lens- you can literally detect this problem from a brand new lens, fresh out of the box at a camera store). This design flaw renders the lens functionally useless at apertures lower than F11.
Simply search "pale purple dot, AF Nikkor 50mm 1.8D" on the internet to see what I mean.
Nikon should recall the product with the intent on discovering if this aberration represents a manufacturing error in a limited batch of AF Nikkor 50mm f/1.8D lenses or a larger problem, and then they should fix it.
When I contacted Nikon about this, they were very respectful, but have not recognized or admitted to this common problem (to my knowledge).
If you are even considering purchasing this lens, try it before you buy it.

Would like to return
Thought the lens would be workable,not so. Rough fit attaching to bayonet mount on my D80,I own four other nikon lenses and never had a problem, tried three times always difficult, I'm scared the lens will damage the recieving end of cameras CPU mount , I upgrade my cameras every couple of years, My first nikon was an EM . I bought the lens in St Martens DA and I live in Canada and the cost of shipping it back/refund is not cost effective. A waste of $140.00CAN
