Rokinon HD8M-N 8 mm f/3.5 HD Fisheye Lens with Auto Aperture Chip and Removable Hood for Nikon DSLR 8-8 mm, Fixed-Non-Zoom Lens (Black)

Best fisheye lens at the affordable price.I couldn't open my package for 40 days as I was out of the station and it worried me what would be inside the package as it arrived from the US and it could have been mishandled at various airports. Luckily it arrived with no damage.I had used a canon version of this lens which was fully manual with no AE. This one looks and feels different. It is much better built and front element looks bigger.what has improved? Better built quality, removable hood, auto exposure and look. 24MP sensor of my D7200 is having no issues in resolving the details.whats Bad? Aperture has to be fixed at F22 to enable aperture control from the Camera and I don't know why.Image Quality is superb even at F3.5.Shall update further after some use/misuse.
