Most underrated camera youtuber. So freakin' good at conveying information!

Thank you very much.

Thank you for this great review! You are the first to talk about the defishing profile and I was surprised at how good these images are compared to the optically corrected previous version of this lens, the 14mm F1.4. There is a very good astro comparison of these two Sigma lenses on the KZbin channel “Nebula Photos”. The problem with the rectilinear corrected lens is that stars in the corners are stretched and enlarged compared to the stars in the center of the image. The same effect when the profile-corrected test image showed the stretched wood in the corner. A little notice: If you compare real images by changing the aperture, there could be an effect of defocusing close elements, which are obviously clearer when switching to F2.8 or F4. In the end, I'd say you should probably buy the Fisheye, even though it's about $400 more expensive. Even if you don't want to take astrophotos, this lens can create image compositions and angles that hardly any other lens can! This gives you unique images!

What's funny is that my Sigma contact didn't know about the defish function of the profile, either.

Pricey but it's simply amazing how they can make a lens like this, with such an extreme fisheye, that gets near equally pinpoint stars in the corners as it does the center. They should be super long streaks. It's magic. There's no wonder it's heavy. The glass it must take, to do this. I'm not sure most people will appreciate what this lens is... but then again, Sigma probably isn't worried either. They know for those whom this is for, will understand. Looks like they nailed it. The Art series continues to impress. This isn't your dads Nikkor 16mm fisheye 2.8D! :D (yes, that's the one I have too ;) )

[@DustinAbbottTWI]

It's definitely a technical marvel even if it won't be appreciated by the masses.

Great review and lens! Haha, garage door for vignette testing :) The Sigma profile for de-fishing the lens makes it quite versatile.

[@DustinAbbottTWI]

It's true. That was an unexpected surprise.

[@mirrorlessny]

Great review, may need to reduce AF sensitivity in camera settings to tame this lens 😁

[@DustinAbbottTWI]

Exactly

[@Bayonet1809]

Would be ideal for astro on a converted Sigma fp L. In fact, with Sigma's emphasis on good astro lenses recently they should really consider making their own astro version of the fp L, like Canon did somewhat recently with the EOS Ra. Sigma fp A?

[@DustinAbbottTWI]

That makes sense.

[@therealj4282]

Fascinating. It certainly gives a unique look to the photos. Any chance of an APS-C version at at 25% of the price? 😀

[@DustinAbbottTWI]

Probably not at a quarter of the price ;)

[@kaimelis]

my dream would be to shave off its hood and put it on gfx100. I could do 4shot 360 panos with 400 megapixels worth of data. I wonder how the entire image circle looks on a larger sensor...

[@DustinAbbottTWI]

I really have no idea how much the coverage extends beyond full frame.

[@cordy-ki7fh]

Since it's for E mount and L mount it's still difficult to adapt it to gfx.
