Entaniya Fisheye HAL 250

Entaniya Fisheye HAL250 lens product features

Entaniya Fisheye HAL250 lens is a high quality and wide fisheye lens beyond compare in the whole world.

This lens has been designed and invented by Entaniya. With our lens of 250-degree, we have greatly exceeded the general 180-degree lens.

Even though the lens is as wide as 250-degree, it has very few aberrations and little fringe which allows it to provide a sharp quality that cannot even be compared to other fisheye lenses.

Entaniya Fisheye HAL consists of three parts: a front lens, a back lens and a mount adapter.
All the parts can be exchanged depending on the purpose of the lens.

The best lens for 360VR

By installing Entaniya Fisheye HAL250 lens to a camera, you can shoot perfect 360-degree footage which covers horizontal 250-degree (vertical length depends on cropping) with only one shot.
By using a composition of two cameras with the exclusive rig, you can create perfect 360 footage. Also, if you increase the number of cameras, you will get even higher resolution.

Interchangeable Lens Parts

Entaniya Fisheye HAL 250 lens can have C-mount, E-mount, EF-mount or MFT (Micro Four Thirds System) Mount* installed. The focal length is exchangeable and it can altered to 2.3mm, 3.0mm, 3.6mm, 4.3mm or 6.0mm* by exchanging the back lens or the mount.
You can adjust the depth of field and peripheral part resolution by changing the focal length. Also, it’s possible to adjust image circle for image sensor.
*some combinations of the parts have limitations

In order to get a sphere footage similar to what you can get with a circumferential fish-eye lens, you can adjust the footage in many ways or for example, deliberately choosing some cropped areas above or below the footage.
By controlling the projection to the image sensor, you can get an ideal size of image for the constitution of multiple cameras.
The lens makes it possible to shoot with the camera you want, a resolution you want and with the number of cameras you want to use.

Special lens

The pipe of Entaniya Fisheye HAL250 lens is made of titanium. In the case of super wide angle of view lens, it is not possible to make the metal around the lens thin no matter what you do.
We liberally use materials equal to those to those used for the aerospace. We demand 50μ machining accuracy.
The band which holds Entaniya Fisheye HAL250 is also made of titanium.
Our big lens is larger than anything you could have ever imagined and the parts of it supporting the lens are also made of titanium.
This is something that used to be unimaginable with the wide angle fisheye lenses until our lens was released.
Our lens makes it possible to take VR photos with unbelievable stability.
