The Panasonic 70-200mm F2.8 G is one of the unique record of relationships declared at the release of the organization's Head program in Sept 2006. However its record goes returning a bit further; it's usually a re-badge of the Minolta AF 70-200mm F2.8 APO G D SSM, which came out up beginning in 2003. At a while Minolta was only creating movie SLRs (its first truly authentic electronic style, the Maxxum/Dynax 7D, showing after the merging with Konica in Sept 2004), so the relationships is developed to secured the Drawbacks full-frame structure, although normally it also features on APS-C electronic SLRs. It's therefore a organic affiliate to the Head 850 and 900 DSLRs, offering a actual substitute to Concept and Nikon techniques towards the top end of the industry.
Like all quick telezooms, the visual program is complex, with 19 components in 16 categories and 4 Extra-Low Distribution (ED) cup components for the difference in chromatic aberration. The relationships features a built-in ultrasonic-type 'Super Sound Routine Motor' (SSM) for auto-focus, eye-catching quick and quiet concentrating. The Immediate Details Concentrate function allows the individual to improve focus place independently whenever they want, and has two modes; 'Standard' stops unique actions of the attention team from disrupting ongoing AF function, while 'Full Time' is usually self-explanatory. The relationships also features three AF-stop management control management buttons arranged around the gun gun gun barrel, enabling the individual to secured focus easily; on Sony's newest high-end DSLRs these can be allocated to other features, perhaps most usefully level of place assessment.
The 70-200mm F2.8G actions impressive competitors, though, from identical relationships such as the Sigma 70-200mm F2.8 EX DG Macro HSM II and Tamron SP AF 70-200mm F2.8 Di LD (IF) Macro. And the value beginning between these relationships becomes somewhat complex on the Head system; because while Concept and Nikon's costly quick telezooms add picture support and weathersealing, this isn't the situation with the Panasonic (because all relationships are continuous via the in-body Amazingly SteadyShot system). The Panasonic relationships therefore provides relatively little on documents to rationalize asking for more than twice as much, but of course requirements tests never quite tell the whole tale. So let's see what you actually get for your cash.

Sony has been grabbing the headlines over the past year or so for its innovative 'SLT' cameras, the mirrorless NEX system and prolific launches of inexpensive SLRs. But it has also been quietly building up an impressive line of high-end full frame equipment, spearheaded by an array of Carl Zeiss branded optics. And it's into this upper half of the company's curiously bifurcated product line that the Distagon T* 24mm F2 SSM arrives, offering a genuinely fast and wide option for Alpha 850 / 900 users, while doubling as a classic semi-wide 35mm equivalent on APS-C cameras. This lens was shown in advanced pre-production form at PMA earlier this year, and has been hotly anticipated by Sony fans ever since.
The design and construction is typical of Sony's Carl Zeiss lenses, with a rather utilitarian, purposeful aesthetic and extremely high quality fit and finish (however in contrast to Canon and Nikon's 24mm F1.4 lenses, it's not described as dust- or water-sealed). The optical design uses 9 elements in 7 groups, including two aspheric and two Extra-low Dispersion glass elements to combat aberrations. For the first time in a Carl Zeiss prime, a built-in ultrasonic-type SuperSonic Wave Motor is employed for autofocus, promising fast, silent focusing and enabling Direct Manual Focus override. A circular aperture diaphragm, comprised of nine curved blades, is designed to produce a smooth, natural rendition of out-of-focus regions of the frame.
Sony's full frame cameras have drawn plenty of critical admiration for their exceptional low-ISO image quality and pared-down feature set unashamedly focused on stills photography. But for the company to gain a real foothold in this high end sector it also needs to convince potential buyers that its lens offerings can match those from its more-established rivals, Canon and Nikon. The two existing Carl Zeiss-branded primes, the Planar T* 85mm F1.4 and Sonnar T* 135mm F1.8, are certainly highly regarded by those who've used them (including us), so can the 24mm F2 follow suit?

However the 16-105mm is more than just an upmarket kit contacts, and provides probably the most exciting central duration variety of any DSLR contacts currently available, which range from a 24mm-equivalent wideangle to a 160mm-equivalent telephoto; indeed for many photography lovers the wider-than-average position of perspective will be more useful than the prolonged telephoto varies discovered on the present plants of superzooms. This follows in something of a custom for this lens's Minolta forerunners, which involved a 24-105mm conventional zoom capability for Negatives SLRs when other manufacturers only provided 28-105mm contacts. Including to the fascination is the point that this is obtained within a lightweight, lightweight program, perfect for journey or just common objective 'walkaround' use. So does this new kid on the prevent have the material to spearhead Sony's designed generate towards DSLR world domination? Let's find out.
