Only One Option:Nikkor Old Telephoto Lens with the Four Thirds mount

Nikon D3300 with Ai-s Nikkor 200mm f4.0

In our household, we have an allowance system, and my allocated amount is small. It is probably much less compared to the average household of my age group. I use that limited amount to purchase camera equipment for biological photography. I mainly use Four Thirds mount equipment from Olympus. The primary reason for this choice is the affordability. Additionally, the ability to use various lenses with a mount adapter is a significant factor.

Earlier this year, I learned that telephoto lenses made by Nikon 30-40 years ago have quite good resolution, so I ended up getting a few. With the Four Thirds mount, the focal length doubles. A 200mm lens becomes 400mm, and a 400mm lens becomes 800mm. This is quite a bargain. Of course, autofocus doesn’t work, so everything has to be manually focused. In recent years, as the latest lenses have been increasing in price, it seems that used manual focus lenses have been decreasing in price. This is nothing but a tailwind for me.

With this and that, as I kept buying Nikon telephoto lenses, I began to feel the urge to try using a Nikon body as well. After several months of deliberation, I finally purchased an 8-year-old mirrorless Nikon D3300. For a few days after buying it, I was excited. I attached a telephoto lens and went outside to photograph birds. However, as expected, compared to when attached to the Four Thirds camera, the focal length is shorter. What used to be doubled on the Four Thirds is only 1.5 times now. I felt somewhat cheated. Realizing this wouldn’t work, I considered using it for wide-angle shots instead. But old wide-angle lenses, when multiplied by 1.5, no longer remain wide-angle. Plus, they are expensive and large. In the end, after shooting with it for a few days, I stopped using it altogether. It seems that, after all, Four Thirds cameras suit me best.
