I have read-200mm VR 18 is not that a correspondent sharper than Nikkor glasses?
My Brother's goin 'to buy this Nikon D5000 month! Now, I know – that there are going to arrive? 1. DX 18-135mm glass? 2. DX VR 18-200mm lens? 3. both the 18-55mm and 55-200mm VR glasses? We have heard 18-200mm VR is not so acute that Nikkor is a correspondent glasses? What to be bought, then? Bring more lenses is no problem with us! Nice I just want sharp photos As visitors exit, they want good landscape and portrait photos of the group, mostly travel-Photography! Also, without a doubt going to join the Sigma 10-20 mm wide glass for us! Is it a wise decision?
What is the resource that you read this? I use the 18-200 mm VR as my main aim when shooting editorial tasks. Here is a picture of an assignment. http://s862.photobucket.com/albums/ab182/fotomanaz/Answers 20album% /? action = view & current = i_DRS7553.jpg and newer 1 = Yes read the metadata from that file, you will see that it was a shot taken well below the recommended shutter speed, and yet is quite strong. Sure, it's a goal that was never designed to be used as a macro lens from edge to edge, where the sharpness is mandatory, but as a tool for shooting editorial duties, there is no single lens that can match it. To cover this range with more clear glass, you have to buy three lenses. 12-24 mm (1,225 dollars) 24-70 mm (1,890 dollars) and 70-200 mm ($ 2,400) lenses. Add the cost of the lenses and compare it with the 18-200 mm VR ($ 850) and can see why the 18-200 mm VR has been so popular. When was first introduced, there was a long waiting list of buyers. I had to wait more than four months for mine to arrive. How do your images are strong, depends on you and your skills as a photographer, not current lenses made by Nikon.
