Canon Unveils Hybrid IS Image Stabilization

Canon says that sudden changes in camera angle can introduce significant blurring in images taken in standard shooting while shift-based shaking is more pronounced in macro photography when the camera moves in parallel to the subject.

The Hybrid IS system uses an angular velocity sensor that has been found in previous Canon IS lenses and incorporates a new acceleration sensor to compensate for shift-based camera shake. The system also has a new algorithm that synthesizes the information from the two sensors to make adjustments.

Canon reports that it is actively engaged in ongoing research and development on D-SLR camera lenses that support Hybrid IS technology and is looking to commercialize the new feature in a wide range of products. The first D-SLR lenses using Hybrid IS are planned before the end of 2009.

Sigma 50mm f/2.8 Macro EX (DG) reviewed at vnphoto.net

Vietnamese site VNPhoto has a review of the Sigma 50mm f/2.8 Macro EX (DG) macro lens.

Sigma first introduced the AF 50mm f/2.8 Macro lens in 1990, then upgraded it and released the Sigma 50mm f/2.8D EX 1998. The latest version is Sigma 50mm f/2.8 EX DG, Sigma is the optimal for digital machines. However, all 3 lenses are designed with optical lens in 10 groups in 9 so the image quality is almost similar. Both are the 2 to 35mm in both FF and have a smaller sensor.
This is probably the lens AF Macro 1:1 cheapest one you can find on the market. Price new (2009) about $ 240 and only about $ 140 used. While price is quite cheap but quality is very good and most websites gave it high rates. Very suitable for those who want to try Macro picture category, but do not want to invest more money.

Carl Zeiss, Leica and Voigtlander macro lenses comparative review

slrlensreviews.com has a review comparing three macro lenses: Carl Zeiss Makro-Planar 100mm f/2 ZF, the Leica APO Macro Elmarit-R 100mm f/2.8 and the Voigtlander APO Macro Lanthar 125mm f/2.5.

From the review:
From price perspective, all three lenses trade at about the same level these days (as of late 2008). However, there's one caveat here (or two). As mentioned earlier, Voigtlander APO Lanthar 125mm f/2.5 SL Macro is no longer being manufactured. Back during production years, this lens was priced at ~US$600. That is the price I paid for it back in late 2006. However, since the lens was discontinued, the price for new old stock, as well as used copies was climbing higher and higher, reaching ~US$1,500. Combination of the hype among users as well as the 'rare-iness' fact certainly contributed to such dramatic hike in prices. However, Voigtlander is not the most expensive lens in the group, since new copies of Carl Zeiss Makro Planar T* 100mm f/2 sells for ~US$1,500, while new copies of Leica APO Macro Elmarit-R 100mm f/2.8 gor for as much as US$4,500 (used copies go for much more 'reasonable' ~US$1,400).
