That is the wrong lens for your camera. The Nikon 12-24mm F/4 is an excellent lens but it is designed for a crop sensor. Nikon calls those DX lenses. Luckily, Nikon makes an even more fantastic lens for your camera, the Nikkor 14-24mm F/2.8 which they call an FX lens. It will give you a wider angle of view, brighter aperture and is very sharp. If you ...


It depends on the lens design, a wide angle retrofocus lens is mainly limited by the front element size, the lens barrel places a hard limit on the range of angles that can see the entrance pupil. As an example of this mounting a filter on an ultrwide can reduce the size of the image circle. This is why separate designs exist for APS-c DSLRs, but mostly for ...


On some lenses the image circle does indeed get bigger as you zoom. I know from experience the Canon EF-S 10-22 f/3.5-4.5 does this. At 12mm the image circle is big enough for a 1.3x crop APS-H sized sensor and by 15mm it is big enough for a full frame 35mm sensor. However lenses such as the EF-S 17-55 f/2.8 vignette at all focal lengths on full frame. I ...


Is that not a DX lens? A quick Google search only turns up the crop sensor optimized lens, so that would be a strong indicator to me that it's why it vignettes on the full frame D800.


All the lenses on this list labeled FX are for your camera. DX is for cropped sensor cameras, your D800 is full frame camera. Some DX lenses can be used in DX mode but reduce your resolution. I suggest you buy FX lens, D800 has very large resolution sensor, in order to resolve all the detail you need top of the line lens; not DX.


Simple answer: No, it does not necessarily do so. I used a Sigma 10-20mm f/4-5.6 lens, designed for 1.5x crop cameras, on a Canon 1D (1.3x crop). It was useable - for generous values of useable; the corner sharpness was nothing to write home about and corner vignetting was quite severe - from 12mm up to 20. Below 12mm, the image circle did not cover the ...
