AI-S NIKKOR 50mm f/1.8S pancake lens review.
There are four types of these lenses, One has 45cm / 1.5ft Closest focusing distance, the other three have 60cm / 2ft Closest focusing distance.
The lens that has 45cm / 1.5ft Closest focusing distance is rare and therefore more expensive.
I have three of them, I’m missing the one that has the closest focusing distance of 45 cm/1.5 ft.
This is how you can Identify the other Nikon pancake lens that has the Closest focusing distance of 45 cm/1.5 ft.
The grip goes between the aperture numbers, it doesn’t on the other lenses.
According to the NIKKOR – The Thousand and One Nights.
Development of the Nikon Series E began with the goal of producing a line of lenses suited to the compact size and lightweight of the very reasonably priced Nikon EM. A 50mm f/1.8 lens was developed as part of the Series E lineup.
As this lens was not sold in Japan, However, the Series E 50mm f/1.8, sold in some regions including the U.S., and the AI Nikkor 50mm f/1.8S were actually sister lenses designed with the same basic optics, but different outward appearance and coatings.
The AI Nikkor 50mm f/1.8S was designed by Mr. Souichi Nakamura.
There were three issues with the AI Nikkor 50mm f/1.8S. It had to be compact, inexpensive, and offer excellent performance. Although the lens design would also be used for the Series E, it had to offer a level of performance equal to or better than that of previous lenses.
One of its most notable characteristics is its lack of distortion. There is only 0.1% distortion of objects positioned at infinity, and just 1% for objects at the minimum focus distance, where the most distortion occurs. There is also very little lateral chromatic aberration.
This lens, released in 1980 to coincide with the release of the Nikon EM (released in 1979 as a Nikon Series E lens), has been a favorite of many users for its slimness and superior rendering capabilities. It also contributed to the appeal of the EM series. What’s more, the same basic optical design was reborn as the AI AF Nikkor 50mm f/1.8S (coatings and such were modified) and is still available today (2016) in the AI AF NIKKOR 50mm f/1.8D. When this lens was reborn as an AF lens, it lost its slim, pancake design, but its rendering characteristics remain the same.
If we compare performance to the latest AF-S NIKKOR 50mm f/1.8G, we find that while contrast and sharpness are not as good at maximum aperture, there is very little distortion. Further, very similar rendering characteristics can be achieved by stopping down the aperture. Differences in rendering characteristics that occur in accordance with the aperture setting make this a lens that can be enjoyed for its uniqueness.

One of its most notable characteristics is its lack of distortion, there is only 0.1% distortion when focus on the infinity, and just 1% minimum focus distance, where the most distortion occurs. It is also a very little chromatic aberration.
The same lens as the Nikon 50mm 1.8D
Can I recommend this lens to anyone, yes I can?
1. Maybe you don’t want to invest a lot of money in a 50mm lens.
2. To someone how is curious about 50 mm focal length.
3. You want to practice using a manual focus lens.
4. Using macro extension tubes with this lens is good.
Whatever the reason is I don’t think you should buy this lens for more than 50% of what the Nikon 50mm 1.8D lens cost.
Low contrast flare test Nikon 50mm 1.8D vs Nikon 1.8 AI-S pancake lens.
Here I’m doing a low contrast flare test in front of a computer screen, Nikon 50mm 1.8D vs Nikon 50mm 1.8 AI-S pancake lens, you can get low contrast flare with Nikon 50mm 1.8D lens just having bright light from the computer screen in front of you and shooting on the maximum aperture.
So how can this be the same lens? when one is so different when shooting with the lenses wide open @ f/1.8.
I think this is the front element of the lens, the plastic in front of the glass is actually reflecting light onto the glass (on 50mm 1.8D) the Nikon 50mm 1.8G is free from this low contrast flare, the lens is built differently than the Nikon 50mm 1.8D to prevent this to happen, and the old pancake lens does not have this plastic at all, and is there for free from this low contrast flare on maximum aperture.
long exposure photography.
For long exposure photography, I have sometimes got a strange reflection from the opening of the aperture blades on my photos like this on the image below, so I cannot recommend this lens for long exposure.
Using macro extension tubes with this lens.
I really like using this lens with macro extension tubes, this lens has the original closest focusing distance 60cm/2 ft, and somehow that works better with macro extension tubes, better than Nikon 50mm 1.8D lens, in my opinion, the 1.8D have closest focusing distance 45cm/1.5 ft.
