Nikkor Fisheye 7.5mm on Sony A7R

This odd-looking lens is one of my 5 fisheye collection, Nikon’s earliest fisheye lens, 7.5mm F5.6 Circular Fisheye lens.  Since it was designed for a Nikon F camera with its mirror locked up, it was not very useful member in my collection.  I did a test shot when I got it from my friend on 80s, but since then it was just sitting in a corner of the box, while me thinking, one day I’ll use it, one day —-. (As I got Yoshi Handy which can take whole circular image on 6×6 format, I didn’t have much reason to use it.)  But when I saw it again, I suddenly realized, Why do I need to go a whole trouble of film shooting, “Mirrorless camera has no need of mirror-up” = So, it came to the Venerable Sony A7 camera.

Yes, in deed, the lens nicely fit onto a Sony A7 body with beautiful viewfinder image.

This lens was designed to use in a scientific field, such as to take picture of the whole sky to measure and analyze the amount of the cloud (so, I heard — don’t ask me what that mean.  🙂 ) therefore the lens got built-in 6 filters (for Infra-red image, Red or Orange filter is the essential). 

My lens seemed to be made in 1967 and amazingly Nikon produced a lot of this lens —- my serial number showed more than 1100 !   (Other than a popular kit lens, the most of the lenses doesn’t sell more than few hundred —– I would be surprised if Canon had sold their EF 85mm F1.2 lens more than 300 all together. —– Think, how many people in the world need to use such special but subtle effect, while able to pay so much money ?   In comparison, scientific institute need to have certain facility = the lens can be sold to each institute in the world while public foot the bill.   Similar to that, even a boring book can sell to each library, as they need to list every book.)

    I enjoy the look of the fish eye especially the image with the flowers appearing to grow outward, escaping its boundaries.

      Thank you Elena. It’s a good view point. Since the lens was so close, almost touching the flowers, only few milimeter move changes the picture = I did straggle to control the escaping flowers. 😀
