It's been a while since I posted and I thought it would good to start off with my review of the Nippon Kogaku GN Auto Nikkor 45mm f/2.8. I bought this lens a few months back after the lunar new year. Although I already have the 50 1.2, the focal length was a tad too tight at times which made it difficult to photograph in some situations. It was then that I started doing a bit of research and found out that Nikon had a 45mm manual focus pancake. After searching on eBay, I bought one that was listing for 170 USD and received it the following week at work only to find out that it wouldn't fit. Unlike Ai lenses which have a notch on the aperture ring for the aperture tap, the 45mm GN did not since it predates the Ai design. It was a few weeks later that I accidently stumbled upon a store in Chungmuro, Seoul that was able to modify my 45mm lens by filing a small notch so the aperture tap would fit. The 45mm has not left my D800 ever since.
