High optical resolution, Good control of aberrations, Compact size and weight
Restricted uses (but it is a specialised lens), Expensive if only being used for the fun element
An updated version of Sigma's 8mm f/4 spherical fisheye, this is the field's widest circular fisheye with autofocus. It's also among the last Sigma film-era lenses to be upgraded with coatings that suppress reflections from digital sensors ("DG").
Very fun lens. Have used on both full frame and crop. On full frame you get a round image, on crop it chops the top and bottom off the circle. I am using the Canon version and have used it on 5D II and III, 50D, 70D, Various Rebels. Always works great.
I've used fisheye lenses for most of my career and for the past 20 years have had to learn to use the circular fisheye lenses for one of my clients. The Nikon 8mm 2.8 fisheye was the best during film days, but finding one years after discontinuance makes them pricy.
Size and quality
Paint issue and infinity focus
I use the EF version of this lens with an EOS 6D. I've used it for both 180-degree IMAX style night time lapses and stitched 360 degree VR photography. Works great, very little chromatic aberration at the edges compared to other 8MM fisheye lenses that I've worked with.
This lens is the one to pull out when things are slow and wouldn't normally attract interest. With this lens, almost every photo taken is in a perspective never seen by anybody, and thus looks very unique.
Sharp all around! It is crisp and very sharp up until its far far edges. F/5.6 and higher get you sharper shots up until F/16. After F/16, you're just compensating for an intense light source., Versatility: The many uses it has can seem almost endless.
Sharpness below F/5.6: Tends to be a bit soft on distant objects, but thats not what the lens is for. The F/3.5 aperture is perfect for objects with no depth, such as astro-photography, but thats not a common photo. Eyes tend to not focus too well at F/3.5.
This lens is STURDY. Very high quality optics. Crisp, clear, and wide every time :D
Expensive compared to what is available from china, but good build quality and chip works great with my D7000. Used for doing 360 panos and recognising lens data from PTGUi. Wish chromatic aberrations were a little bit less but I am sure this is as good as the best out there and probably just...
I purchased the lens on Ebay , original from japan, it is wonderful sharp lens so I was thinking why all images on internet are so blurry .. this type of lens need at last f11 to be sharp from the corner to the center, anything below that will effect in DOF I use it for VR HDRI panoramas it will...
Great for 360° work seems a over priced for such a old design. Uses in camera AF motor so make sure your camera is designed for that works fine with a D810 but slow to focus hunts for focus.
Love this lens. It gets everything into the picture. The images are nice and sharp on my D800. If you want the autofocus to work you will need a higher end Nikon body with a screw drive auto focus motor.
used for panoramic view and tours. Best to shoot at least 3 photos instead of the two that the product can do - at least for a virtual tour
