17-70 f/4 AL (IF) SDM
A 17-70mm lens that incorporates the Pentax SDM focusing system and allows focus as close as 28cm
This lens is an indispensable tool for ambitious photographers. With a 26 - 107 mm focal length (in 35mm film format) it offers the crucial 'plus' of additional range when normal standard zooms generally extend to 45 or 55mm. Not only the focal length range is remarkable: with the KAF3 lens mount it relinquishes the classical mechanical autofocus drive for the first time in favour of faster and quieter ultrasonic technology. The lens construction: 17 elements in 12 groups including 2 aspherical lens elements - guarantors of outstanding pictures. Important details such as fixed aperture throughout the zoom range provide for excellent control.
Smc DA 17 - 70mm's lens mount is KAF3-type which means that with K100D *ist D *ist DS and *ist DL the focus can only be performed manually.

05/24/2012 05:46 PM Samsung Galaxy S3 review The Samsung Galaxy S3 will rival the iPhone with its gorgeous 4.8-inch 720p resolution screen, impossibly slinky casing and quad-core chip.
05/24/2012 04:52 PM JCB Toughphone Pro-Smart review Thick and heavy, the JCB Toughphone Pro-Smart likes a bit of rough and tumble. It's unquestionably the most robust Android phone available.
05/23/2012 05:31 PM Toshiba Satellite L875-10G review The Toshiba Satellite L875-10G gives a good performance for both office tasks and gaming and doesn't break the bank doing it.
05/23/2012 01:34 PM Motorola Razr Maxx review The Razr Maxx may have stamina, but if you value speed and style in a phone, there are slicker devices in the Android and iOS camps.
05/22/2012 05:54 PM Samsung DV300F review The Samsung DV300F is a small, feature-packed camera with loads of creative filters and a decent video mode.
05/22/2012 05:47 PM Samsung HMX-W300 review The sporty Samsung HMX-W300 is an inexpensive smart phone-like movie camera that shoots great videos and is built to take a few knocks.
05/22/2012 05:18 PM HP Folio 13 review The HP Folio 13 compromises on size, weight and screen in order to keep the price competitive but it may appeal as an office ultrabook.
05/22/2012 12:09 PM Sony 55HX853 review The 55-inch Sony 55HX853 produces gorgeous 2D and 3D pictures, has impressive sound quality and a very strong line-up of Internet services.
05/21/2012 05:30 PM Panasonic TX-L47WT50B review The 47-inch Panasonic TX-L47WT50B offers great 2D and 3D picture quality but the touchpad controller is not great and its menus are dated.
05/21/2012 03:20 PM LG Optimus L7 review The LG Optimus L7 has Ice Cream Sandwich and a big shiny face, but under its hood lurks a sluggish, single-core engine.
