Macro action now at A href='http://www.digitalcamerareview.com/default.asp?newsID=5457&review=sigma+105mm+macro+lens+f2.8+fantastic+image+quality'>Digital Camera Review where they tested the Nikon flavor of the Sigma 105mm f2.8 macro lens.
Dxomark is back with another lens evaluation, this time their labs decided to pixel-peep on the new Nikon 18-140mm DX VR. By slightly changing the focal range (previously 18-135s), Nikon made it easier for the average consumer to tell.
As of the time of writing, this lens goes for $600 on its own at Amazon and B&H Photo and Adorama. Although it may be a better value if you buy it when it is bundled with a Nikon DSLR in one of the standard kits or during upcoming (presumably) combined purchase Nikon Instant Rebates.
On the Nikon mount, Pop Photo has published their review of the Nikon 18-35mm f3.5-4.5G full frame lens at their website. It is full frame, otherwise it would have to answer for the Sigma 18-35mm f1.8 DC (APS-C) lens :)
Photozone.de is back with the APS-C review of the Nikon 70-200mm f2.8 VR II workhorse lens. By "APS-C" review, they are reviewing this 35mm full frame lens on APS-C DSLRs.
As of the time of writing, this lens goes for a small kingdom's king's ransom of $2,400 at Amazon and B&H Photo and Adorama. However, if you are willing to make trade-offs, you can get the first generation refurbished by Nikon for $1550 at Adorama.
