Most Often Used for Street Photography
A full frame format lens which can be used both on the full frame and APS-C sensor DSLR cameras.
When mounted onto an APS-C sensor DSLR camera the field of view works out to around 36mm (equivalent to full format camera) so it handles like an average wide angle lens most often used for street photography. The f/2 aperture doesn't really qualify the lens as as an "ultra large aperture" any longer. Although we can thankful that the more
conservative aperture size the Zeiss is a little less expensive than the other f/1.4 competition manufactured by Canon or Nikon and perhaps more significant than that is it's a way simpler to engineer. With f/1.4 apertures, lens makers struggle to overcome intense aberrations in order to make some sort of functional image available at the maximum. aperture compared to the optical situation where beginning at f/2 is far more lenient.
The lens build quality is on the plus side of outstanding having a lens body totally made from metal which also includes the silky smooth fluted focusing ring. Thre is a constant lens physical length at all focus settings and there's also a stationary inner lens tube A factors which which may be somewhat disappointing for for a few people is weather sealing which Sony doesn't talk about A petal-shape lens hood is included which is made of quality plastic.
The lens includes the Sony "supersonic motor" (SSM), which is an autofocus drive using ultrasonic waves patterned after the Canon USM and the Nikon Silent Wave system. The AF is quick and virtually noiseless. DMF ("Direct Manual Focus") is also included.
You can use the Zeiss lens on your Sony NEX system by using the LA-EA1 Alpha-to-NEX lens adapter made by Sony. The autofocus stays functional and it works out better than the Sony 50mm f/1.8 DT lens I've already talked about. Although, don't count on an SLR feel AF quality. This arrangement looks somewhat strange but it remains a workable option.
The Distagon T* 24mm f/2 ZA SSM is a true manifestation of the times, staying within the APS-C range. The lens is remarkably sharp from corner to corner of the image frame all the way from f/2 tol f/8. The minimal CAs level additionally assists in increasing the subjective perception of sharpness even more so. There's only a faint to moderate degree of barrel distortion. If you look hard, You may find some light falloff at f/w at the image corners but it's not field-relevant issue beginning at f/2.8 on. The bokeh quality is really good for this type of lens (in
descriptive terms - just average) and the bokeh fringing is also under control. The Zeiss lens has exceptional build quality and the AF performs a flawlessly. In this class of lens, Zeiss has attained the highest plane of perfection and inspite its pricey tag it earns highest recommendation!
