Launched back in spring 2007 the EF 16-35mm f/2.8 USM L II is the latest ultra-wide zoom lens made by Canon. Regarding its rather steep pricing of around 1400€/US$ it's primarily targeting the professional market segment. Compared to its predecessor Canon claims to have "improved the peripheral image quality at the wide-angle end". Certainly an interesting aspect regarding the rather mediocre full format performance of its little cousin (EF 17-40mm f/4L) here. Well, we'll see whether this statement survives our test procedure.
The build quality of this lens is basically identical to the EF 17-40mm f/4L - it's exceptionally high just as you would expect it from a Canon L lens. No wobbling whatsoever and smooth controls - almost perfect. The lens is also designed to survive in harsh conditions with a sealing against dust and moisture. The outer length of the lens remains constant although the inner lens tube moves a little according to the zoom setting. Needless to say - the front element does not rotate during focusing or zooming operations. Read the whole review here. You can buy the lens here.

PMA 2009 saw the announcement of this lens for the micro-four-thirds system. The lens is very small and uses a complex design of 16 elements in 12 groups, with 2 aspherical elements. As the four-thirds system mount produces a 2x ''crop factor,'' the lens produces an effective field of view of 14-28mm when mounted on a Panasonic G-1 or GH-1.
The lens features a constant ƒ/4 aperture and a fixed lens hood; the large protruding front element precludes the use of screw-mounted filters. Read the whole review here

TOKYO –Nikon Corporation is pleased to announce the introduction of the DX-format 35mm single-focal-length lens AF-S DX NIKKOR 35mm f/1.8G, which offers a picture angle equivalent to a focal length of 52.5mm in FX and 35mm formats.
The AF-S DX NIKKOR 35mm f/1.8G features a large maximum aperture of f/1.8 enabling effortless handheld shooting in dark settings, such as a dimly lit room. This lens makes it easy to create large, beautiful blur effects. And the built-in Silent Wave Motor (SWM) ensures fast, quiet autofocus, even with SLR models that do not have a built-in motor, such as the D40 series and D60. Read the whole press release inside.

The Canon EF 24mm f/1.4L II USM was introduced in the lead-up to Photokina 2008, as an update to its pre-existing 24mm f/1.4. Introduced in December 1997, the previous version of the 24mm f/1.4 was probably getting a little bit long in the tooth, despite having all the fixtures and trimmings of an L-class USM lens.
The upgrade to the lens is fairly substantial; it features 8 diaphragm blades in the aperture instead of 7, and the blades are now rounded. The lens elements have been regrouped, and an additional group is now present. Two ultra-low dispersion (UD) glass elements are used instead of just one. Finally, the new version of this lens is slightly heavier (100 grams) and a bit longer and wider. Read the very good review here. You can buy this lens here

The SP AF 70-200mm F2.8 Di LD (IF) Macro is Tamron's latest lens, announced at the end of February 2008. A fast telephoto zoom for the more budget-conscious photographer, the design features 19 elements on 16 groups, including three Low Dispersion (LD) glass elements for minimizing chromatic aberration. Tamron say the lens is 'packed with features that allow stress-free photography', and accordingly these are indicated by the plethora of initials packed into that painfully protracted lens name. 'SP' designates this to be a member of Tamron's top-line 'Special Performance' range, 'Di' indicates that it is 'Digitally Integrated' (i.e. optimized for DSLR use, but still covering the full-frame 35mm format), and IF reveals that it incorporates an internal focusing mechanism. Finally the 'Macro' description provides a clue to one of this lens's more interesting characteristics, a minimum focusing distance of 0.95m, which leads to a class-leading reproduction ratio of 0.32x; slightly ahead of the Sigma equivalent's 1m/0.28x, and significantly better than the ~1.5m more typical of this class.
