A really quick review, I can add more to this later.

7Artisans just released a few weeks ago the 14mm f2.8 lens. I got it as soon as it was released.

First impressions is that it's a really solid lens. It's well built in a metal body. Many lenses today have a lot of plastic in them and they feel like it. This felt solid like a tank.

Second, I liked that even though it was a 14mm lens, it could take a 77mm filter. That's a super cool feature.

Third, it's manual focus.

Fourth, it can be used for video as it has an option for a click or declick for the video.

Fifth, it's sharp. The stars I took photos of looked really sharp in it.


Now for the one piece of bad news. It's sad that such a great lens has what I consider an issue that totally kills the lens for me.

And that's the flaring it gets from light sources at f2.8, and even at f3.5. It does clear up later but you can't shoot this lens wide open. It's not a pretty flare that one could decide is artistic. It's a ruin the image type of flare.

Look for yourself.

2. Street light at the side of an image.

#3 - Night time. It was bright out, the moon is up. I wanted to see how the moon affected it. The sky is brighter from the moon, so the flare is not as prominent, but it's still there. Right now it's cloudy, so I can't take more star images.

To Be Continued:

I will add some 100% crops of the corners and the stars later.

o_O Those street light shots are in serious Whiskey Tango Foxtrot territory! Almost up there with Lens Baby artifacts.

It needs its own nomenclature - flare just doesn't do it :)

Perhaps this is purely a nightime lens for MW shots then. Interesting that they have a RF mount version.

I would say it's not for night time Milky Way use. With that flare it's going to be a daytime lens.

If you only used it with a 0% moon, and if there were no ground based lights, it could be used. But that really restricts when it can be used. I shoot thd MW up to a 25% moon, so for me, the moon can be in the image, especially if shooting pre-new moon.

It looks really good outside of that flare. What's bad is there is no way to fix that flare in processing. CA can be corrected, some softness can be corrected, the normal flare bubbles can be corrected in processing, but not this one.

Hi, I found this review and discussion when googling comments about the lens. Surprised to see these strange flares - to me it looks like there is something wrong with the copy of the lens. In other reviews and sample photos I find in the web there are no such problems visible, whereas in the images here it seems any bright source of light would make an ugly flare. Could it be you just got a copy that is broken? Or did you have a filter or something attached to the lens?
Just wondering. I guess that kind of problem would be a no-go in a lens development program.

Welcome Shelle!

I agree, one would think it would have been a no go in testing. But it disappeared by f5.6, so my thoughts were that most of the inexpensive fast lenses will seem to always say it's soft wide open, it has CA, etc, but it clears up by f5.6. So many of the reviewers (in general) seem to assume that lenses are not actually used wide open since they look great when they are stopped down.

I will have to check some other reviews since it's been out a while. The build of the lens is really nice, and the price was right too. My hope was to have it as a back up WA nightscape lens, as all of my main Nighttime lenses are f1.4 or f1.8.

Thanks again, I will have to look into this again.
