Related Questions and Answers

Q: 1. Does this lens has the usual fisheye heavy barrel distortion or is it rectilineal like the Voigtlnder 12mm?

A: Well, it's an extremely wide angle lens, so yes, it does distort the image and no, it's not rectilinear. That said, the projection is not a pure fisheye ... it's more of a stereographic graphic projection meaning that it has less of a pronounced central bulge to the image and things look a bit more natural. For a pretty good discussion of the lens and the projection, check out the review from a site called admiring light . I'm not the author of the review and have no relationship with the site, but found it while researching the lens for myself. There's are reviews of the both the old and new version of the lens. I found it very useful when I was considering my own purchase ... and BTW ... I love the lens. :) Definitely a special use item, but a lot of fun to shoot with. And very well built.

Q: 2. Does it have these known black corners, or can you see the whole image?

A: This lens will have a rectangular field of view. There will not be obvious vignetting in the corners of the image.

Q: 3. Is lens hood removable?

A: No but it can be machined off then it's called a shaved lens.

Q: 4. is this compatible with Sony Alpha a6000 (B&H # SOA6000B) ?

A: What kind lens correct siny A6300?

Q: 5. What is the lp/mm of this lens?

A: Unfortunately the manufacturer does not supply this information.

Q: 6. What size filter fits this lens?

A: M49 0.75

Q: 7. I assume this is a 180-degree on-the-diagonal fisheye that covers the entire APS-C rectangle? I guess it must be with the built-in petal-type lens hood.

A: Yes, the Samyang 8mm f/2.8 covers the entire sensor and provides a 12mm focal length and full 180 degree angle of view.

Q: 8. Is this lens exactly the same as the Rokinon equivalent ?

A: Yes they are exactly the same just rebadged from the same assembly line.

Q: 9. That 52mm filter adapter has glass in it, right? Can I get it out and put 52 to 72 step up adapter on it? Not sure why they put glass...I'm afraid to touch it:)

A: Yes you can just use step up ring

Q: 10. Please excuse my newbie ignorance, but is it possible to put an ND filter on this lens?

A: No, the lens doesn't have filter threads.

[Manual] The Fujinon CF series lenses provide low distortion, accurate images on camera sensors up to 1 and are relatively inexpensive. The CF12.5HA-1 is physically large compared to the body size of most modern machine vision cameras, but the barrel distortion is noticeably less than most compact lenses can deliver. This lens works perfectly with both 1:1.2 sensors and 1 sensors. I've even used it on 5MP industrial cameras and it punches well above its weight given that it's only rated for use on 1.5MP sensors.

[Fixed Focus] We have been using Fuji CFxxZA-1S, where xx = 8mm, 16mm, 25mm for a while now. Recently bought the 25mm EFL lens from B&H, who are great!

One comment, the 25mm lens, while to the design, behaves with a slightly shorter EFL. So, I recommend looking at this document when designing: CF-ZA Series: FUJINON Lens Shooting Range Chart.pdf.

The CFxxZA lenses provide excellent brightness uniformity across the field. The 25mm lens provided near full intensity at the edge field. (We know this because we were at 85%, better than the illumination source spec.)


Like the 8mm (a challenging design), we can flat-field and distortion correct the imaging system with outstanding results.

B&H is outstanding (aka they rock!)

[Fixed Focus] B&H delivered this product to Ireland on time. We use this lens for high speed capture up to 5000 fps, the F stop range (1.4 to 22) allows a lot of light to get to the 1 sensor, which is critical for high frame rates. I found the quality of the optics on this lens excellent for the low price. It's a sturdy construction and the lockable focus and aperture are very useful. The 100 mm MOD suited our application to allow us to get close to the subject. The viewing angle suited our application subject size of approx. 15 mm x 15 mm. If a larger subject is required the lens was able to cope by simply moving further away from the subject or use lens extension adaptors tubes. Overall very happy with this lens.

[Fixed Focus] I use a 25mm f/1.4 lens in fixed geometry at an image-object distance of 350mm. With a 2/3 industrial CCD, the Fujinon CF25HA-1 gives a slightly sharper 100x80mm image with less darkening at the corners compared to the much smaller and cheaper Fujinon HF25HA-1B under the exact same conditions. The latter only has the advantage when size, weight or cost are important.
