This lens is ideal for sports and wildlife photography. The newly designed optical system has one fluorite element and two UD-glass elements to obtain high resolution and high contrast. Also, the minimum focusing distance was reduced to 5.5 m. Extender EF 2x can be attached to increase the focal length to 1200mm while retaining AF (with the EOS-3).

The HP StorageWorks Ultrium 1760 Tape Drive is HP's fourth-generation of LTO tape drive technology capable of storing up to 1.6TB per cartridge in under 3 hours. HP Ultrium half-height drives are designed for server customers in direct attached storage (DAS) environments where hard disk and system bottlenecks can impede data transfer rates. To further protect the most sensitive data, AES 256-bit hardware data encryption provides easy-to-enable security to prevent unauthorized access of tape cartridges. By using LTO-4 hardware data encryption, not only is data fully capable of being compressed therefore maximizing capacity, encrypted backups are completed without a loss in performance. Capable of data transfer rates up to 160MB/sec, HP's exclusive Data Rate Matching feature further optimizes performance by matching speed of host to keep drives streaming and enabling the fastest performance of any tape drive in the industry. The Ultrium 1760 provides investment protection with full read and write support with LTO-3 media, and the ability to read LTO-2 cartridge. By doubling the capacity of previous generation Ultrium drives, HP customers now require fewer data cartridges to meet their storage needs, significantly reducing their IT costs and increasing their ROI.

Freecom offers a full portfolio of Midrange and high-performance backup tape-drives for professional use.

LTO Drives "powered by HP" are ideal for server environments with high capacity and performance requirements, larger application servers, such as large databases and e-mail servers. Freecom LTO-drives are based on leading HP Technology and offer One-Button-Disaster-Recovery and Tape-Alert.

The EF100-400mm f/4.5-5.6L IS USM is the first EF telephoto zoom lens with a high-magnification zoom range of 100 to 400mm. This is the first L type zoom lens with IS (Image Stabilizer) system. The dual-mode IS mechanism corrects camera shake blurring equivalent to two shutter speed steps. The IS Mode-1 works for normal shooting and IS Mode-2 is suitable for panning shots of a moving subject, stabilizing images in viewfinder. The optical system uses one artificial crystal fluorite and one Super UD (Ultra-low Dispersion) glass lens elements (3rd and 7th), which thoroughly correct chromatic aberration. The minimum focusing distance of 1.8m is achieved throughout zooming range. The floating system in rear focusing system is employed for the first time for EF zoom lens to achieve a high definition for the entire focusing range. A ring USM (Ultrasonic Motor) drives high-speed and silent AF and full-time manual focusing. Linear zooming design with zooming friction adjustment ring gives a good operability of this lens.

With 12 SFP slots, the DGS-3612G provides a full fibre environment for long distance Ethernet infrastructure. It is particularly suitable for ISPs in their Metropolitan Area Network (MAN) deployments. In addition, four 1000Base-T copper ports acting as combo with 4 of the SFP slots are included for flexibility.

With D-Link Single IP Management (SIM) technology, up to 32 switch units -regardless of the model- may be combined in a virtual stack. Multiple switches can be configured, monitored and maintained from any workstation running a web browser via a single IP address. The stack is managed as a single object, as all stacked units are identified by this single IP address. A simple yet powerful web-based interface allows the administrator to perform most management and configuration tasks.

The DGS-3612G includes advanced routing features, such as OSPF v2, Passive Interface, Not-So-Stubby Area (NSSA), Equal Cost Route and RIP. Multicast services such as IP-TV and Video on Demand (VoD) are supported with the inclusion of protocols such as IGMP, MLD and PIM. With Double VLAN (802.1Q-in-Q) support, ISPs can create Layer2 Virtual Private Networks (VPNs) and transparent LANs for their customers.

A complete set of security features is provided for connectivity and access control. These include Access Control Lists (ACLs) based on MAC address, switch port, IP address and/or TCP/UDP port numbers. 802.1X Authentication and MAC address control functionality is furthermore featured. The switch also provides central management for administration access via TACACS/TACACS+ and RADIUS. In addition, when implemented in conjunction with a D-Link NetDefend firewall, this switch is able to automatically quarantine any host displaying abnormal behaviour. This mechanism, D-Link's ZoneDefense, provides proactive network security by preventing viruses from spreading through the network and thwarting harmful network attacks.

The DGS-3612G switch provides VLAN support including GARP/GVRP, 802.1Q and Guest VLAN to enhance network security and performance. The Guest VLAN feature assigns the user to a "Guest VLAN" dynamically if the user does not login on the RADIUS server. If authentication is successful the user will be assigned to the VLAN that is associated with the login information. The switch implements a robust set of multi-layer (L2, L3, L4) QoS/CoS features to ensure that critical network services like VoIP, ERP, Intranet and video conference are prioritized. Bandwidth control allows administrators to set traffic limits on each port, ensuring a committed level of service for end users. For advanced applications, per-flow bandwidth control allows easy fine-tuning of service types based on specific IP addresses or protocols.

In addition, a unique feature, D-Link Safeguard Engine, allows administrators to configure thresholds that limit the impact of packet flooding to the switches CPU typically caused by virus/worm outbreaks. This increases the switch's reliability, serviceability and availability.
