Would this lense still appear as a fisheye lense if the BMCC is only using the center of the glass? Would this fix wide angle issues? Is there a better option for super wide?

Anyone know this?

I read about this in Vimeo comments.
This lens works. There are also calculations on it. But the sigma 8-16 is somehow better.
A characteristic that is wideangle and not fisheye is seemingly an advantage.
Price is also lower, so there you go.

Cheers

Wouldn't the L glass deliver better quality picture?

Disclaimer: I am a complete diIettante, however.... I use both on my 7D. The canon is still a true fisheye even on the smaller sensor. It's great for time lapse and weird stuff. The Sigma is all wide angle goodness with no distortion. Much better for narrative than a fisheye which is more of a specialty lens. The sigma wide angle (for me) has far more uses and is tack sharp. I'd put it up against L glass any day.

But again, note the disclaimer.

As David says, the Sigma 8-16mm zoom is a rectilinear lens; it doesn't distort the way a fisheye lens does.

Although the BMCC's field of view utilizes the somewhat flatter center of a fisheye lens, the distortion of the fisheye is noticeably more than that of a rectilinear lens.

Both of the lenses mentioned by Cuboirs are demonstrated in Marco Solorio's excellent BMCC vs 5DM3 comparison video:


The Tokina 11-16mm f2.8 zoom is another relatively inexpensive rectilinear lens. Not quite as wide as the slower Sigma 8-16mm, but still quite wide.

To my understanding "L glass" means that these lenses have 2 major features:

- cover full frame (not needed)
- constant aperature over the whole zoom range
(- eventually additional weather-sealing)

It does not have anything to do with sharpness, vignetting, etc.
I have already stocked up on a Sigma 8-16mm. =)

Thanks for all the reply's.....I guess I'll look into the tokina and the sigma now

Has anyone used the canon 14mm L series on the BMCC yet? How is it
