I have been shooting industrial design, transportation, interior, and travel photography with primarily Nikon Cameras and Lens with excellent results for over 50 years. When switiching over from film to the more affordable DX/Cropped Sensor DSLR D70, D90, and D300s I ran into the typical issues and cost factor of finding an affordale ultra-wide lens solution to supplement the Nikon 20mm F2.8 lens that was so usefull when used on my 35mm F100 DSLR for shooting interiors of retail stores, yachts, and cars without having to buy the expensive 14mm 2.8 series lens. The Nikon 10-24mm Zoom has become more useful in the areas of travel photography in the narrow streets of Greece, Italy, and other European locations where I photograph a lot of fishing ports along with my maritime photography. I especially find this lenes invaluable when photographing U.S. Coast Guard Cutters, large Navy Ships exteriors/dockside and on-board activities at commissioning ceremonies. The lens has an excellent build quality and weather sealing gasket for use in many of the areas where dust and moisture environmental conditions are an everyday problem. The ability to use a front element protective filter, unlike the Nikon 14mm F2.8 or 14mm 24-70 2.8 makes this lens less vulnerable to accidental damage. The careful use of the supplied lens shade is important to reduce lens flare issues from off angle lighting, and directly shooting into the sun. I have gotten terrific color rendition and fantastic color saturation and image sharpness when reducing the exposure by one thrid stop. I plan to add a FX DSLR by Nikon if it prices out between the D7000/D300s and the D800. I plan to purchase the Nikon 16mm-35mm F4 VR for use on both DX and FX formats and continue to use the Nikon 10mm-24mm especially when traveling with my D90 or D7000 to save weight and space. My present travel choice is packing the D7000 and the 10mm-24mm, 16mm--85mm VR, 70mm-300mm VR, Nikon G 50mm F 1.8, and a Coolpix 7000 for hiking and back-up. With this set-up I can shoot practically anything and everything that captures the total experience of discovering new places and people---and end-up with publishable professional results. My excellent Nikon equipment helps me to capture---truly magnicifant "optical eye candy."
