Review on 📸 Sigma 15mm f/2.8 EX DG Diagonal Fisheye Lens for Nikon SLR Cameras: Captivate with Distinctive Fisheye Effects by Angela Mitchell

I wasn't sure how long I'd been using something like this. Fisheye lenses are a type of novel lens with limited uses. However, I use this lens more than I thought I would. In fact, I use it more for landscape photography than my other more conventional lenses. Obviously there is significant bias. With this type of lens, you're working with distortion rather than trying to avoid it. This can create a very unique image. I enjoy this landscape lens. By tilting it down a bit I can make a boundary of the horizon which again looks like the curvature of the earth. (Obviously not) It makes for some interesting looks with a unique twist. Focusing is pretty quick, but it doesn't matter. The depth of field is so great that focusing is not critical. Sharpness is excellent. The sharpness is excellent in the middle. To be honest I don't know. The world around us is not flat. So anything that falls near the edge is obviously not the same distance as the center. Because of the large depth of field, they come out pretty sharp, but that wasn't really important for the type of photography I do. (So if you read other reviews about edge sharpness, consider how you're going to use this lens.) I use it with the Nikon D800. With a resolution of 36 Mpix, all the flaws are visible, but I didn't see them. I recently took a photo and printed it out at 16" x 30" (obviously cropped at the top and bottom). At this size, it was surprisingly sharp. At this rate I was able to go to 32x60 and get great sharpness. This lens exceeded my expectations.
