Nikon DX VR 18-200 mm F/3.5-5.6G - Review by Thom Hogan
Thom Hogan has recently posted a review of the Nikon DX VR 18-200 mm F/3.5-5.6G, a compact, lightweight and packed with an array of advanced features, the AF-S DZ VR Zoom-Nikkor lens offers 18-200mm f/3.5-5.6G IF-ED focal range length and 11.1x zoom coupled with Nikon ED glass, Silent Wave Motor and enhanced Vibration Reduction (VR II).
“Sharpness is excellent throughout most of the range, with f/11 being the point of maximum sharpness on my sample once you get to 100mm. At the wide angle end, though, there’s actually little to distinguish the central area in one aperture from another–go ahead and use maximum aperture if you’d like. At all apertures at 200mm you’ll see a bit of softness, with the best apertures being f/11 through f/16. (I should note that I’ve seen tests from others that say the opposite–that their sample was a tiny bit soft, especially in the corners at 18mm but pretty darned sharp across the board at 200mm. “

Nikon 105mm f/2.8GED-IF AF-S VR Micro-Nikkor - Review by KenRockwell
KenRockwell has posted his review on Nikon 105mm f/2.8GED-IF AF-S VR Micro-Nikkor and he does not recommend the lens by writting;
“I tried three samples at PMA 2006. All of them didn’t autofocus very well on my D200. They would often not get good focus, so the green focus confirmation dot in the lower left of the finder wouldn’t light, so the shutter wouldn’t release in S mode. This is bad. My old 105 mm AF, not even D, focuses much more reliably
Pass on it and get the older 105 mm f/2.8 AF instead. That older lens sells for $700 and this new one sells for $830. I’m hoping the focus issue I saw will go away. I’ll let you know if I try it again.”
