e.g. Nikon 12-24 AFS or Sigma 10-20?? Any experiences or thoughts?
I have a 12-24 DX Nikkor. The main gripe I have with it is that it's DX, ie you can't use it on your film Nikons or an FX camera. Well, you can, from a focal length of about 19 to 24, it doesn't vignette. But that just makes me want wider! 😱
The good things about this lens are many. At 12mm on DX, it's the widest lens I have. It's got all the 'iq' stuff internet people rave about, and it is very flare-free. I can include the sun in a photo, and it brings only minor blobs with it, and has a great star around the sun itself.
This lens is also one of only two that perform well on my D70 IR camera. Most of the other Nikkors I have show a focus shift in the IR.
No.. unfortunately this isn't the case..Everything I've read with respect to Nikkors is that you get what you pay for.
The results from the Tokina 11-16/2.8 are good and I'm thinking about getting one. I currently use a 17-55/2.8 as my standard lens so the Tokina would go well with it. Peter Hamm's review of the Tokina is worth reading.
I own the Nikkor 12-24/4. I use this lens commercially for real estate photography.
All the wide DX zooms from Nikon, Sigma and Tokina are horrible. The have a boat load of CA, they are soft at the edges wide-open and they are slow (except for the 11-16/2.8 which has reasonable speed). While there are always sample-to-sample variations, the published reviews indicate the Nikkor is the best performer, i.e. the least horrible. Many people are happy with their Sigma and Tokina lenses... for good reason I'm sure. I do not doubt there are samples of the Sigma/Tokina WA DX lenses that are as good or better than the worst samples of the Nikkor.
The question is: how much are you willing to pay to get that next 5% improvement in image quality? This seems to be THE question for lenses.
But the Nikkor seemed to me like the best way to meet my needs. The Nikkor 12-24/4 the build quality is excellent and the lens gets the job done. It is very sharp and vignetting is never an issue in practice. The Nikkor has relatively low geometrical distortion which is important for my work. Unsurprisingly, the performance is lowest at 12mm. I use mine at 16 mm 90% of the time. When I shoot interiors I like to use as much ambient light as possible and achieve fill with with 2-4 externally triggered strobes. This means I shoot mostly at f 5.6-8. The lens works best with slight underexposure as this minimizes fringing artifacts. The CA is manageable in post if the frame is not over-exposed. If one of the channels overflows, then CA/fringing correction becomes problematic. For critical work check all the RGB histograms. Don't fear under exposure. RAW images provide effective shadow recovery at ISO 400 (with the D300, a bit less so with the D200). The lens will flare when shot directly into the sun which can be a problem for exterior property shots when the sun is low in the sky.
Despite the CA and fringing, I would buy this lens again. I can make money with it and it has held up well. I do not trust the quality/consistency of Tokina/Sigma products, but I understand they may be excellent alternative selections.
