#Kameken Nikon Ai Micro Nikkor 200mm F4S (IF) Accessories: F&R caps The front element is quite dirty. I have circled the particularly concerning points in red. It would be best to judge from the sample images, but judging from the sample images, it seems to be usable without any problems. Sample Image Common Data Camera used: SONY α7 Aperture: f4-16 ISO: 100-1000 No image processing It's a telephoto macro lens that I think has finished its role, as there are no announcements of new products. When taking pictures of insects and other creatures, a medium telephoto macro lens of around 90-100mm will make them wary and they will run away, but a telephoto macro lens of around 200mm allows you to get closer without making the subject wary because of the shorter minimum focusing distance. This product is a 200mm telephoto lens, but it is surprisingly compact because it has a maximum aperture of F4. Even so, the depth of field becomes shallow, so tripods are often used, and a tripod collar is also included. Also, I have heard that this product has weak infinity focus, but while there is indeed some softness in the focus plane at the maximum aperture, I didn't have such a bad impression because you usually stop down the aperture when using infinity focus. It's a category that you don't often come across these days, so I hope you enjoy it.
