Samyang 8mm Fisheye

Postby omnipix » Mon Mar 14, 2011 6:53 am

We are yet to see the Samyang 8mm Fisheye added to the VRWave lens database. Hopefully soon!
This lens is the best entry point fisheye on the market. Price is typically around $300-$400 USD and it is sold under many names.

Including:
Samyang, Falcon, Polar, Opteka, Rokinon, Vivitar, Bower, Walimex Pro among others.

In some cases it is marked as a 6.5mm or 7.0mm but all are the same Samyang 8mm Fisheye lens with the Vivitar the only to have a updated "sexier" design and look.

Image

It is a fully manual lens, meaning it has no electrical contact to the camera body. So focus and aperture settings are all done manually, which is no biggy as you will most likely settle on an aperture and hyperfocal distance and never change them.
Though the manufacturer claims it to be a 8mm lens, PTGui results show it is more like a 9mm lens and this comes down to its unusual stereographic projection.

Shooting configuration on a APS-C sensor camera is as little as 4 rotational shots + zenith shot (4+1z).

Image
This example shows 4 shots at -15 degrees and 1 zenith shot at +60 degrees.

It is advisable to shoot 5 or 6 -15 degrees rotational shots with double zenith shots +60 180 degrees opposed (5+2z) or (6+2z).
This gives you greater overlap and generally much better places for control points.

You can read more on this in my original thread on another forum.

Hi VR Wave,

may we call you Marc?? ;)

I am quite sure this renewed website and forum will have great attention and give a lot of infos to Oldies and Newbies. I keep my finger crossed. And thx to you personally, to spend your time to run this site.

You really should add the Samyang 8mm lens to the database. Great Optics, Fov near 190° cause of special construction, though manual, I prefer it to Sigma 8mm. Specially to shoot 4 around in shaved version on FX Nikon Bodies -full frame bodies.

I have tested it on D700,D300s,D7000,D90,D200. Pics can be downloaded on demand. Same workflow as you already got to know on another thread. A great addition to those who use a zoom lens and like to add a fisheye with great optical quality for a very good price. Or for newbies with lower budget. Price in EU is around 240€.

Regards,
Heinz

I guess you could but Tib most likely wouldn't answer to it.
I think you have confused the forum skin developer?

Not quite getting the reference, I googled my name :D The first result is indeed a professor, the second a doctor, none of whom is me.

Here's the initial database entry for the Samyang 8mm: http://www.vrwave.com/panoramic-lens-database/samyang . I still have to determine the correct FOV numbers for fullframe (can be tricky, as it varies with the F-stop) and APS-C.

The more I read about this lens, the more interesting it gets. The price/quality ratio is great, making it a good choice in an entry level panorama setup.

The projection is quite different from other fisheye lenses, being very close to "stereographic", which apparently is a desirable feature for panoramas, because of the lower radial compression.
