Being a owner of five quality Sigma EX lenses, I am happy and impressed with the latest Sigma lenses announcements at PMA 08. The gigantic green beast Sigma 200-500 f/2.8 EX DG is a showcase of Sigma’s achievement in the photography lens market. Labeled as the “ultimate wildlife lens”, APO 200-500 f.2.8 is “the world’s first lens to offer an f/2.8 aperture at 500mm focal length”. It was actually displayed at PMA 2007 as prototype.

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.

Nikon has just announced the D60 DSLR that appears to be a replacement for the D40(x) models and an array of SLR lenses. Read the details by following the links below.

I am a little disappointed by the D60 because I was expecting a D80 replacement. The new lenses are a little boring as well. Nikon’s consumer grade zoom lens lineup just became even messier with the introduction of the DX Nikkor 16-85 f/3.5-5.6G ED VR. The other two lenses are more targeted towards professional photographers in an effort to revamp Nikon’s aging full frame lens offerings. I guess it becomes necessary with the recent introduction of the D3 full frame (FX format) DSLR camera.

DPReview got some juicy details of the new Canon EOS 450D, aka Rebel XSi. It has many first time features on the entry level Canon DSLR, such as Secure Digital (SD) format flash card, spot metering (4% at center), verification data (original decision data), highlight tone priority (“expose-to-the-right”), ISO in viewfinder, custom settings menu (My Menu), high ISO noise reduction (NR), etc.

With its low price of $800 (body only) and the nice set of features, the new Canon EOS 450D/Rebel XSi will put some pressure on Nikon’s aging D80. Since D80 has been out for more than a year now, I’d imagine the successor to D80 will be out soon (want some rumors?).

Hot spots refer to shinny areas on the faces of the portraits that are caused by strong light reflections from oily or sweating skins. They are typically on the nose or forehead but they can appear anywhere depending on the angles of the camera, subject, and the light source. In this tutorial, I will show you a very easy way of removing the hot spots while preserving natural-looking skin details using Nikon Capture NX. Read More…
