Three shots from the Sigma 17-70 F2.8 DC, first is a full zoom at 70mm Macro with a 100% crop inset, second shot is at full wide 17mm shot through a glass roof.
First shot with the new 17-70 lens, of a garden orb spider. Shot from around 3" (7cm), Macro seems crisp and bright. Shot was F16 - 70mm - 180/sec - ISO 200 - Spot Metering on K10D.
Q1, At 323 metres (1,059 feet), it is the world's tallest all-residential building, when measured to the top of its spire. This shot was from under a laminated safety glass verandah in the tower courtyard, hence the colour cast. F8 - 1/350 - ISO 100.
The coffee drinker - (babyccino sans coffee) F4 - 1/160 - 53mm with onboard flash.
IMO this lens is a winner, for the price the quality is equal to any other lens I have tried.
