Here is the lens review from the forum...

its a great lens. it was one of my first purchases for my k-7

[Zealex]

I've had my eye on the 8-16, but it's very expensive. This seems to be a cheaper alternative, and it's on sale! But it still seems like a huge investment, especially since I'm a beginner. Though from what I've seen, WA lens tend to cost more than other lens.

The Sigma 10-20mm is a great lens, whether in f/3.5 or f/4.0-5.6 form. I already have the Pentax DA 12-24mm but if I didn't this Sigma would be on my short list.

[interested_observer]

It took me about a year and a half to save up for the DA 12-24 about 5-6 years ago. That was with one son in college and another one getting ready to go. Now that the DA is in the $900 range, even considering the $100 off coupon that Pentax has, this price is very appealing. This Sigma is under half that. I would need to think long and hard, plus - its sales like this that I would wait for. I have my lenses, and really not contemplating acquiring any more.

The link to the review on the lens here on the Forum puts it a hairs breath under the DA. For the money, especially at this price, I do not see that the difference in image quality or use will be really noticeable.

Anyone able to test this lens for coma distortion

Thoughts on how this compares to the Samyang 14mm please?

I'm considering for entry level astro work, but this on picks up auto focus and the zoom flexibility also...

Thanks.

Evening,

I just acquired the GPS unit about a month ago. So, that has been the real extent of my astro shots - well other than trying it from time to time, and coming out sort of ok. I will say that wide and fast, is a nice combination, so the Samyang 14mm and some high ISO 1600, 3200 and 6400 should be a winning combination. I have read a few reviews on this lens and they say that it works quite well.

Same sentiment here too - I've seen enough really great shots from the Sigma I would not hesitate to get it if I did any landscape or architectural shots. Super wides are one of the reasons I shoot with interchangeable lens cams. When I first bought a good DSLR, I took a trip to Washington DC, but I didn't have a super wide at the time. Now that I have one, I really want to go back and see what I can do. Under $400 for this lens is pretty sweet...

The 10-20 is a very good lens. Mine was the f3.5 version, but they test fairly closely together, with the f4.0-5.6 ahead in some areas. I'd still have my copy if I hadn't bought the 8-16.

My favorit is the 10-20/3,5 EX DG HSM von Sigma

I have been checking the samyang/rokinon 14mm 10mm and 16mm, 16 appeals to me because of the lower f stop in comparison to the 14 and 10mm but the 10 has been getting awesome reviews I want it for photographing the northern lights and f2.8 and below is suggested so I just have to decide if width or f stop is more important does .8 really make that much difference or does the difference in 4mm warrant $200+ difference sigh decisions decissions

My thoughts exactly!

I'm looking at astro from a static untracked mount perspective, stacking multiple short exposures instead.

Price will probably determine my eventual choice. Probably end with mint second hand, looking for a 14mm Samyang in the $250 region.

The code doesn't work.
