ICYMI: Sigma 14mm f/1.8 DG HSM Art Astro Sample Images
« on: June 16, 2017, 12:25:11 PM »
In case you missed it (I did), Sigma Japan posted a couple of sample images of the soon-to-be-shipping Sigma 14mm f/1.8 DG HSM Art. If the sample images are to be a sign of things to come, this is going to be a stellar lens.

This lens and the Sigma 24-70mm f/2.8 DG HSM OS Art will be available for preorder on June 22, 2017 at 1AM EST.

thanks Mike

The shots note a tracking mount was used.  The lights on the shore in the sample images seem to show some evidence of this.

Full exif data is not provided for the sample images taken with the sigma lens, and no details are provided for the comparison lens.

Thus this marketing material is heavily biased and should be taken with a large grain of salt...

true. but the lack of coma is a good thing.

Dang!  Might have to sell the Rokinon 14mm 2.8.  Looking forward to the first real world user results.
I wonder what the distortion looks like.  The Rokinon was a bit challenging.

I did notice these shots when they were first produced...  excellent news and a not utterly insane price.. if a little too much for my pocket right now.

I'm living in the UK, forecast for tomorrow night is 17C 95% humidity, clear sky, dew is going to be running everywhere..  I wonder how water resistant it is?  Am I going to have to clothe it in dew prevention gear or will it cope in the nude?  (yes I'll need a heater strip for the front element regardless)

The "crops" at the bottom don't match the boxes drawn onto the images.

This is marketing material from Sigma, and it isn't even done well. This is basically useless as far as informing potential buyers.

Looks good... if the shading also is reasonable at f1.8 I'm sold.

That's a good point.  I couldn't even find the enlarged star patterns anywhere in the box, so who knows where those enlargements came from.

Wow this is impressive. I am looking for another ART lens to add to my collection and I don't have a wide angle prime lens. Distortion seems low which means it can be used for portraits wide angle shots.

probably not the best lens for portrait shots unless you are happy with a massive perspective distortion. straight lines remain straight but your angles become highly distorted.

Those are marketing materials intended to create a buzz, e.g. this thread.

As usual, its best to wait for the reviews prior to forking the cash.

...Just when I thought I had the perfect lens quiver!!! (Gnashes teeth)....OK...this may be a stelllar lens (I own the Sigma Art 20mm, 50mm & 135mm (all lenses which best the Canon offrerings as far as I am concerned), but I will wait for some street reviews as Sigma touts my 20mm f/1.4 ART lens (killer general use lens!) for astro, which it is not good at because of coma. I use my Sam Yang 24mm instead. What is a stellar 14mm lens, is the Rokinon SP f/2.4. I picked up a new one recently for $800 from a seller in NY on eBay. That is half the price of this new Sigma. The Rokinon is fantastic for the price but is only MF which is appropriate for the stars, where one cannot rely on AF, but if this new Sigma is as good and delivers accurate AF for all of my other photography needs, I am seriously interested. Sigma has become quite the exciting lens company and has definitely upped Canon's lens specifications in recent years.  8)  I do not think that Canon would have delivered the new 35mm f1.4L if Sigma was not around! Sigma has shaved some of the lazy arrogance off of Canon IMHO.canon is paying more attention now because of Sigma.  Nice to see this for us consumers!!!
