p.11 #1 · p.11 #1 · Laowa 15mm f/2 FE: Rolling Review and Comparisons



So this is all based on a few test shots, but the Laowa vignettes more than the Zeiss (but not as much as the CV.) The Zeiss cleans up as you stop down, and while the Laowa does as well, it still shows more vignetting at f/11 than the Zeiss. But stopped down, the Laowa doesn't vignette as bad as the Zeiss does wide open.

I hope that makes sense.

So I did get the Laowa yesterday, did some quick and dirty testing this morning. I think it's a keeper, probably going to put my CV 15 on the chopping block. I don't do enough sunstar shooting to keep 3 15mm lenses. Given the sale price on a new Zeiss ZE 15mm, I'd have to probably set a crazy low price for it to move.

I did notice that the Laowa seems to have a flatter field than the other two lenses. When shooting 45 degree angle test shots, both the CV and the Zeiss gave sharp foreground corners by f/8

Agreed completely on the flat field at infinity. You really have to check your focus carefully and stop down accordingly if there are both far/near elements in the frame.

The flat field really helps with astrophotography though...especially if everything in the frame is at or near infinity. With my copy, if you nail the focus in the center at F2, the stars will be in focus across the frame and you won't need to refocus at other apertures.

Interested in my first UWA and have been swaying between this and the CV 15. Read through the entire thread and found some references to my questions but still unclear .. with no EXIF, does Peak focusing work? What about exposure metering in-camera?

Thanks

Everything works. You just won't get exposure values transmitted to your files. It's not a big deal but a negative aspect of this lens.

Sunstars are actually pretty nice from its 'straight' blades (14-point sunstar against Loxia's 10-point)
To me, an annoying negative is the lack of EXIF transmission especially since this lens was designed for the Sony E-mount.


I agree about the lack of electrical contacts, what where they thinking at this price point.

Really agonising over this lens. If the coma wide open was as good as @ f/2.8 Iíd have no hesitation. I have heard that Rokinon were supposedly going to release the 14 f/2.4 in FE mount, but itís almost a year since they said that. That would be my first choice for landscape, architecture and astrophotography, but the 15mm is so good in every other way than coma. But I also am looking longingly at the Loxia 21mm. Donít want to buy 2 lenses at this stage, since my 12-24 will get used the most for landscape photography.

I could get the Rokinon for my Canon, and then decide between the Laowa or the Zeiss for the Sony, I can always use the Rokinon with a metabones. The Rokinon other than being slower is considered even better than the Sigma 14 f/1.8 for coma, but you couldnít go wrong with either. Sigma though is a monster which is why Iíd trade some speed for size and weight of the Rokinon.

Argh too many nice primes for the Sony.

I consider the Laowa 15/2 a f/2.8 lens for astro. However, it can be used wide open with some fixing in post (basically removal of coma which mainly appears on big stars..)

The Loxia 21/2.8 is a marvel and imo, the best wide-angle for the E-mount. It's also great for astro from wide-open. (with a hard stop infinity for stars)

Currently I carry the 12-24/4 for landscapes and Laowa 15/2 + Loxia 21/2.8 for nightscapes. (Ok...I use the Loxia for both. )

It's likely that Sigma and Tokina will release new ultra wides for the E-mount next year, so it looks like the Sony E-mount is about to get saturated with lenses. Many are hoping for a Batis 35 and a Loxia 28 as well.

^How do you remove coma from the big stars?
the Laowa 15/2 is my next lens (though I don't need it until April).
In fact I just received from Germany the Astronomik CLS Clip filter for experimentation and
also in anticipation of the cores return.

The Batis 18 is also an excellent astro lens if the FL works. Focus by wire might bother some people, but I've found it easy enough for point sources at night (stars).

Justruss I have the B18...don't like the fly-by-wire...want something closer to a hard stop at infinity but realize that doesn't exist. I'll keep the Batis, just so lightweight for when the walk is long for landscaping. One really big reason I'm to add the Laowa 15 is the size.

Ah yes, the Tokina Firin 20 is a nice lens and I believe next year they will release AF Firin lenses. Maybe they will release a 14/15mm themselves. I wonder if Sigma could release a 14 f/1.8 for FE that is much smaller and lighter than the DSLR version. UWA lenses are one area mirrorless can have a real advantage.

I might get the Loxia for now and just sit tight on the UWA prime until next year.
