The unique design of this lens should certainly appeal to those who record video with their DSLR. Although the lens is perfectly capable of shooting stills as well, those who primarily take images, rather than videos may want to look towards the slightly cheaper standard version of this lens.

  • +

    Excellent sharpness in the centre when stopped down, Good build quality, Stepless aperture is an excellent feature for those recording video, Inexpensive, Stereographic projection

  • -

    If shooting stills, the unique design may be more a curse than a blessing, Geared focusing and aperture rings can be a little uncomfortable

The Samyang 8mm f/3.5 CS Fisheye is certainly a more than welcome addition to the Sony NEX system. The near-stereographic projection doesn't look quite as extreme as in conventional fisheye lenses despite the similar field-of-view so its applications are in fact broader.

We were very curious about the results of this review. Recently, we have been positively surprised by Samyang 85 mm f/1.4, which, around maximum aperture, could face even the most renowned competitors. Now, Samyang 8 mm f/3.5 finally arrived.

  • +

    Good build quality, The use of difficult in making but good for photos stereographic projection, Excellent image quality in the center of the frame, Very good side-of-the-frame image quality, Relatively well-controlled coma, Insignificant astigmatism, Little vignetting

  • -

    Significant chromatic aberration around maximum aperture, It is impossible to use filters

Fits my canon 750D great and does the job for a lot cheaper than the other brands

This lens is NOT for a Canon - change the listings and save someone else the hassle!

If you want a lens for panoramic or 360 photography, just buy it. I'm absolutely blown away by the image quality and the stitching results are fantastic. I was hesitant at first but honestly, it's a great lens. Don't even think about buying the canon equivalent.

This high quality item was at a great price & delivered promptly !

Very difficult (nigh on impossible) to get pristinely crisp professional quality photographs, however it's such a great lens for point and shoot pictures and for the price you can't knock it really! I love it still :)

Good lens for the price

19 August 2016

A brilliant lens for my Canon 550D .. A tip to achieve full image focus, set focus length to 1.5 m and app f8 in good light conditions ..

Highly recommended for those who want to play with a fish eye but do not want to pay a fortune for it.

  • +

    Very nice fish eye. The manual focus is no problem from 5.6 on. Optical and build quality are excellent. The price is low.

  • -

    The minimum focus distance is longer than for more expensive fish eyes. This is the only point what could be improved.

great Value for money

Not bad at all but not quite a canon! But to be fair it's a 1/3 of the price so I would say it's pretty good for the price.
