Ultra Wide Angle Prime for Astrophotography?
- Thread starter Panza
- Start date
I don't know if you have to use filters or not for astro but if not, the 14-24mm is one of the better. One of the more expensive too. As a prime, the 24mm 1.4 is equal at CA. Shorter you'd have to go zooms to have better CA but then you trade in sharpness depending what f/ used.
I checked those values based upon the D610 sensor. There's nothing for the D750 yet and if you use another cam than that, it might differ.

I was looking at the 24mm 1.4 but many people can vouch for the disrupting coma making it less usable for astrophotography wide open, a shame really, for that price point the 14-24mm seems more viable... 14-24mm is one of the gods of astro : ) Unfortunately it also shoots past 2k in price range. For that much money, I'd sell and replace the old 80-200 to the 70-200 VR II, which I plan on doing ... eventually.

Wow, I had never even heard of this lens until now. It looks to do just about everything that you would want from an astro lens.
- Low Coma
- Sharp
- Large Aperture
- Good wide open performance
- Reasonably priced
Thank you for the suggestion. : )!!

If you only use it wide open it is at its worst but when I check here for the D610 "worse" is reasonable.
Tests and reviews for the lens Nikon AF-S Nikkor 24mm f/1.4G ED mounted on Nikon D610 Measurements - DxOMark
I have lenses that do worse but in astro CA might have a very different effect.
Have you ever played wit the 16-35, 18-35, or 14-24 to see which you prefer : )?I have this lens, and use it for landscape and gives me a good feeling
I have the 18-35mm and am satisfied with its performance although it doesn't do equally well at every length but for its price it's good. It has some distortion at 18mm as to be expected of a wide. With a pod and careful positioning it isn't a problem but when not paying attention to that, it can produce horrors.
Even while I more and more use the 24-35mm part for landscape shots, there are times I like them to be wide and 18 simply doesn't cut it there. I have a 14mm Samyang for that but it has to stop raining before I know how it performs. I can tell you it's a lens that ugly only its mommy can love it.

You might want to wait till february. I have a feeling sigma will release a 24mm art in CP+ also rumored is Tamron releasing 2 primes as well. maybe a WA. there is the amazingly stellar 15-30 2.8 VC lens being sold within a month thatll sell for $1100. from the MTF, it will surpass the legendary 14-24AFS. getting mine in april. this will sell like crazy. not like the tokina 16-28 2.8 which is god and compared nicely to the nikon. this tamron will surpass the nikon. im almost certain
The 16-35 focal range seems to be "enough" for me. Anything wider and I will look for a lens that gives that subtle fisheye lens distortion hehe. I'll admit, I try to make sure that the system looks as good as the pictures that come out of it. When I see hideous lenses or combinations I'm a bit turned off!
Speculations! Let's find out what the next few months will bring out. Sometimes rumors don't live up to the hype!
I'm not bothered; I'm behind the cam. It's the rest of the world that has to face the ugly lens.

thats what im saying. wait till february, I think there will be something interesting from tamron and sigma. no one knows what. the tamron 15-30 VC is not a speculation though. thats going to be brilliant.
or you can go with the rokinon bower samyang offereings also. theyre very nice.
btw, how a lens looks physically affects your decision to buy it?
I have played with the 16-35. It looks good. But i don t like the corners and the distortion.
I haven't needed wider from my 16-35 yet for landscapes and close indoors, anything more than 15 and I think that fisheye distortion starts to look artistic : )!

Distortion is something that can be fixed. And if it can't be fixed today, maybe next week. All it takes is software and evidently knowing where to point the lens. I ruined plenty a shot by not paying enough attention to that. Now I level my pod and cam as if my life depends on it.
I usually pick a lens solely on sharpness. It's hard to fix that.
It's part of my decision making process. Yes. I take into account if it has the requirements I'm looking for first. Then I make the rest work for me. Car, motorcycle, and bicycles, snowboard, skii's, girlfriend, etc. (Don't tell the girlfriend I said that.)
And yeah, I can wait until February : ) Rokinon was in consideration from the get-go, because it seems like a bargain but I had heard that you need a good copy of the lens which can be hit or miss.

the problem with rokinon samyang bower is also build. they arent very durable. the manual focus ring will slip after use. the hood wont thread and click in place after time. I know cause different videogs who use them suffer from this issue. especially the 85 and 14mm. many also use the 35 1.5 cine and that seems really nice. I think the cine versions may be a bit better but I think with them you get good IQ but best for video. less for stills, unless you stop down 1-2 stops. not the sharpest wide open. you decide youre buying
I think sigma will deliver either the 24mm or maybe surprise with the 85 1.4 and tamron are rumored to have 2 primes. their 90 macro is excellent. but who knows what theyll be. im hoping a 50 and 85. I dont think theres a point for them to bring the 35 as sigma has dominated with that lens. and a 50 is ok but it has to be better then the nikon for less or aroudn the same. 24 would be great 20 would be great but no good options for an 85 1.4 the sigma is ok, but is more useable from f/2 and the nikon is overpriced. so for $1000 and a killer performance thats on par with the nikon will steal tons of sales. maybe a 135mm although that FL isnt really in demand. not many buy the 135DC nowadays. well wait and see. I think by mid january well get some leaks.. and not D750 leaks..something good.
I can't yet say how durable the Samyang 14mm will be but what annoys me is that this lens is all focus and aperture ring which forces me to grab it with the front when attaching/detaching. If I just continue the habit of my other lenses, I'm moving the aperture ring or focus ring the other end before it clicks. I can see how that starts wearing them down when this frequently happens.
The focus from infinity to close is quite a distance too. Fastest method would probably require me putting the cam on a pod, grab the focus ring with both hands, and do a cartwheel.
It feels like eternity before I reach infinity. For fine focus that evidently is not bad. All in all I have to say it feels more solid than some I got of the more respected brands. The Samyang feels like a lens when I hold it, some others I have like kid toys. Not that such necessarily means much in regards to performance.
