Looking for a wide angle lens for my D7200. I see three from Nikon, 10-20mm f/4.5-5.6, 10-24mm f/3.5-4.5 and 12-24mm f/4. The last two are much more pricey than the first, yet they all seem to have a similar range. Are there other reasons besides larger aperture to consider the last two options? Also Sigma has a 10-20mm f/3.5 for around $650, any experience with this lens?
Remember on a AF-S DX Camera the "Crop Factor" of the lens, Nikon = 1.5, Canon = 1.6, others ??, the crop factor is determined by the Sensor size. It affects the actual F.O.V. of the Lens.
