Tamron just announced at PMA 2008 three new lenses with built-in AF motor for Nikon mount SLRs. This is a great news for users of Nikon D40(x) and future users of the newly announced D60, which do not have a AF motor in the camera. The press release is posted at Tamron USA website with the specifications.
- AF18-200mm F/3.5-6.3 XR Di II (model A14NII)
- SP AF17-50mm F/2.8 XR Di II (model A16NII)
- 70-300mm F/4-5.6 Di (model A17NII)
The first two are designed for cameras with APS-C sized (DX) sensors (labeled as “Di II” lens) and the last one also works for camera with full frame (FX) sensor. No word on availability yet.
Previously, Tamron announced AF18-250mm F/3.5-6.3 Di-II LD Aspherical (IF) Macro with built-In auto focus motor for Nikon. Sigma also has a similar 18-200mm F3.5-6.3 DC with a built-in motor for Nikon.
Many have seen over-exposure problems with the 17-50 f/2.8 in TTL-BL flash mode that might be a design flaw. I hope this new version brings a fix to it.
