Full-Frame Lenses on APS-C Cameras: What Changes?
All the following lenses (with the exception of the Sony 16-50mm f/2.8 DT Standard Zoom) cover the full-frame (24 x 36mm) format provided by the current Sony A99 and the previous top-of-the-line A900. When they’re used on APS-C-format Sony Alphas, such as the A77, A65 and A58, their effective focal lengths increase by a factor of 1.5x due to the smaller format, thus narrowing their angle of view to simulate a longer focal length lens. For example, when the Sony 16-35mm f/2.8 Carl Zeiss T* is mounted on an A77 its equivalent range becomes 24-52.5mm—in effect, a normal lens instead of a wide-angle at the long end, and a wide-angle instead of an ultra-wide at the short end. Sony APS-C-format lenses, including the 16-50mm f/2.8 DT, are not compatible with full-frame Sony cameras.
All-Around Zoom Lenses
The Sony 24-70mm f/2.8 Carl Zeiss T* Standard Zoom lens is an extremely versatile lens
for shooting weddings. At the 24mm setting it covers an 84-degree angle of view, ideal for photographing large and small groups, guests at reception tables and overall views of the wedding hall, all with minimal perspective distortion. At the moderate telephoto setting of 70mm it covers a relatively narrow angle of view of 34° and can be pressed into service as a portrait lens for shots of the bride and groom, parents and siblings, or for documenting the ceremony. Its constant f/2.8 maximum aperture facilitates shooting without flash in low light and using moderate ISO settings for maximum image quality and minimal noise. At wide apertures in the f/2.8-to-f/4.0 range, it yields shallow depth of field for creating striking pictorial effects by blurring the background or foreground. Its nine diaphragm blades form a circular aperture and help in capturing natural-looking bokeh in out-of-focus areas.
This compact Carl Zeiss lens also delivers outstanding image quality and detail thanks to its advanced 16-element, 13-group optical design that incorporates three Extra-Low Dispersion (ED) elements and two aspheric glass elements for enhanced color correction, low distortion and consistently high performance. It also employs a proprietary Zeiss T* coating to increase light transmission, minimize flare and ghosting and increase contrast. Its SSM Super Sonic Wave motor uses an advanced piezoelectric design to achieve high torque at low speed, and a rapid start/stop response to provide swift, silent AF action that’s crucial when shooting HD video. It also provides Focus Mode and Focus Hold functions to increase AF speed by limiting the focusing range, and aid precision by locking-in the focus point. When used on an APS-C format Sony Alpha, this lens is equivalent to a 36-105mm, which is also excellent for general event coverage and classic portraiture.
Prime Macro Lenses
Both the Sony 100mm f/2.8 and 50mm f/2.8 prime (single focal length) macro lenses provide a 1:1 reproduction ratio, enabling them to capture life-size images on the sensor. That’s why they’re an excellent choice for shooting details—a wedding ring close-up, the lace pattern on a bridal gown, a boutonniere being pinned to the groom’s lapel—that help to enrich the story of the event. Macro lenses are also valued for delivering exceptional image quality at longer shooting distances, making them excellent choices for portraits and general photojournalistic coverage. Both have wide f/2.8 apertures that facilitate shooting in low light at moderate ISO settings and the creation of artistic effects, such as sharp portraits with soft backgrounds, by using selective focus and shallow depth of field.
The Sony 100mm f/2.8 Alpha A-Mount Macro lens is a medium telephoto that 
provides an ideal perspective for portraits on full-frame and APS-C-format cameras (it becomes a 150mm equivalent on the latter.) It focuses to 1.2’, enabling frame-filling headshots and dramatic close-ups of small objects. Its eight-element, eight-group design ensures critically sharp imaging down to its minimum aperture of f/32, which maximizes depth of field. Its nine aperture blades produce round, natural-looking bokeh. The fact that this lens provides longer working (lens-to-subject) distance at any given magnification makes it easier to compose and capture skittish subjects. Thanks to its Auto Clutch, the manual-focusing ring does not turn in AF mode, which improves handling and prevents accidental focus changes. The lens has Focus Hold and Range Limiter buttons to enhance AF speed and focusing precision.
The Sony 50mm f/2.8 Macro Prime lens is a versatile high-performance normal 
lens with 1:1 macro capability. Its minimum focus distance of 7.9” makes it ideal for extreme close-ups, and its 47-degree angle of view provides a natural-looking perspective for general event coverage. Its seven-element, six-group design provides exceptional sharpness in general shooting, and it stops down to f/32 to maximize depth of field. Its seven diaphragm blades form a rounded aperture, which helps to produce smooth, rounded bokeh, and it has Focus Hold and Range Limiter buttons to enhance AF speed and precision.
Wide-Angle Prime and Zoom Lenses
Wide-angle, ultra-wide-angle and wide-angle zoom lenses can solve many of the problems encountered in shooting in confined spaces, and expand the photographer’s creative options. They’re essential for capturing large groups, wide areas like the dance floor, large interior spaces such as the entire nave or chapel, an overview of the reception, pictures of the bride and groom in the limo, and pre-ceremony preparations. Wide-angle lenses are also great for capturing people in spontaneous moments of joy and emotional intensity that define the event.
The Sony 20mm f/2.8 Wide Angle Prime lens is a wide-aperture, ultra-wide-angle 
lens that provides 94° of coverage with minimal distortion on full-frame cameras and a 30mm equivalent focal length on APS-C-format models.
