I'm tempted to have it cleaned and ready to be used for future DSLR, D80 or 90 or whatever Nikon names it later..
Are you planning to have yours cleaned ,Luis ?
Actually, no. As things are, there is a Nikkor 50mm f/1.8
on the market with an accessible price. And that one will autofocus on a D80 or superior, which my Series E 50mm won't do.
The lens has been sent to cleaning (on a local photo shop) about 25 years ago, but "it came the same". I would assume the money and trouble involved in sending it to Nikon would surpass what would be need to buy that modern one I mentioned.
I've taken a couple of test photos. Here they are.
I'm not sure I got the focus to be 100% perfect.
Here it is, the Series E 50mm at f/2.8 (see full size here
And here we have the same lens, this time wide open at f/1.8 (see full size here
One thing I noticed right away was that there was no barrel distortion. I guess that was to be expected.
Now, to the thing that really surprised me. This 1970's budget Nikon 50mm, when wide open at f/1.8, is by far superior to the 2005 Nikkor VR 18-200mm, when wide open at f/4.8!
Here is the VR 18-200mm, set to a focal range of 50mm and wide open at f/4.8 (see full size here
Is there any colour chart, for colour comparison, that is freely available?
I also did a brief portrait session and I'm really pleased with the results (can't post the photos on that one, sorry).
