Verdict
The Sony 70-300mm f/4.5-5.6 SSM G impressed during our APS-C format test and
it is capable of delivering high quality results within the full format
scope as well. The resolution figures are generally excellent at 70mm and
still very high towards the long end although the border and corner
performance drops somewhat more here. Lateral CAs and distortions are
generally well controlled and not really field-relevant. The lens produces
some light falloff at max. aperture but this is rather typical for full
format lenses tested within their native scope. While not formally tested
the quality of the bokeh is pleasing - an important aspect for a tele lens
although the comparatively slow max. aperture is surely a limiting factor
here at times.
The build quality of the lens is very good and a step above than the
mainstream. Thanks to the new SSM ("Supersonic Motor") AF operations are
very silent although it doesn't transform the lens into an AF speed demon.
If anything the Sony 70-300mm f/4.5-5.6 SSM G has one problem - its price
tag. At around 800/US$ it is not exactly a cheap item and it faces a
rather stiff competition from the new Tamron AF 70-300mm f/4-5.6 VC. However
, regarding its very high build quality and the optical performance it's
actually a sound offer.
Verdict
The Zeiss Distagon T* 24mm f/2 SSM may not be as fast as its Canon and Nikon
counterparts but it's capable of delivering a better image quality at
comparable aperture settings. It avoids the glory but also the difficulties
of an ultra-large f/1.4 aperture in favor of a much higher peak performance.
There's still a bit of corner softness at f/2, but beyond it unleashes its
full potential. The image quality is already very good at f/2.8 and
excellent if not outstanding (within the full format scope) at medium
apertures. The Zeiss lens produces a moderate amount of barrel distortion
which is typical for a lens in this class. Unfortunately the Zeiss designers
were not able to solve the common vignetting problems at large aperture
setting - the light falloff can be very obvious here. The quality of the
bokeh is very good for such a kind of lens (albeit average in absolute terms
) and bokeh fringing (LoCAs) is also very well controlled. The build quality
of the Zeiss lens is exceptionally high thanks to an all metal design and
tight tolerances. Sony's SSM AF delivers a flawless performance offering
both very fast and near silent AF operations. |
