What We Like
+Exceptional value at $129 for a ultra-wide circular fisheye lens
+192° field of view captures extraordinary perspectives with circular projection
+Fast f/2 aperture excellent for low-light and astrophotography
+Sharp image quality with minimal chromatic aberration thanks to ED elements
+Compact and lightweight at 268g with solid metal construction
Worth Knowing
−Manual focus only with no autofocus, requiring careful composition and focus technique
−No image stabilization and no electronic contacts for EXIF data
−Bulbous front element prohibits filter use and increases risk of impact damage
−Extreme field of view makes composition challenging; fingers and camera body easily enter frame
