Sony70-200mm f/2.8 G Telephoto Zoom Lens
Sony 70-200mm f/2.8 G is a fast telephoto lens compatible with APS-C format and 35mm sized sensor cameras, covering a focal length range of 105-300mm with the former. It is one of the last to be based on the original Minolta designs.
The letter “G” is the title means that this lens belongs to so-called ‘Gold’ series lenses, which represent professional quality. The lens’s f/2.8 maximum aperture is available at all focal length settings, with the minimum aperture of f/32.
As to its optical construction, the 70-200mm f/2.8 G contains 19 elements in 16 groups with four ED (Extra-low Dispersion) glass elements to correct chromatic aberrations and provide high resolution across the full zoom range.
The lens offers a built-in SSM (Super Sonic wave Motor) similar to the USM motors on Canon lenses or Nikon’s SWM motors. It provides fast, almost silent and accurate auto focusing. The 70-200mm also features internal focusing that allows the use of angle-critical attachments like polarizers and graduated filters.
The lens is a perfect match to ‘full-frame’ cameras like the A850 and the A900, where its 1.34 kg weight is better balanced. It is housed in the solid metal body. Unfortunately, no environmental sealing has been included.
Lens Reviews:
Photoreview.com.au:
This is fast, professional quality telephoto zoom lens for Sony’s A850 and A900 DSLR bodies and match the capabilities of ‘full-frame’ Exmor sensor. But be prepared to carry this really heavy device. And you won’t find close focusing and macro capabilities in it.
