Sony 24mm f/2 SSM Carl Zeiss Distagon T* SAL24F20Z
(From Sony lens literature) The Distagon T* 24mm F2 ZA SSM (SAL24F20Z) features the acclaimed Carl Zeiss Distagon design and rounds out the existing Planar (SAL85F14Z) and Sonnar (SAL135F18Z) models also developed in conjunction with Carl Zeiss. It is intended to appeal to experienced photographers looking for a large-aperture wide-angle lens of real distinction.
The Distagon T* 24mm F2 SSM (SAL24F20Z) functions as a wide-angle 24mm lens on full-frame cameras with 35mm sensors, or as a 36mm equivalent lens ideal for general use on cameras with APS-C sensors. Jointly developed with Carl Zeiss, it features the highly-regarded Carl Zeiss Distagon retro-focus lens configuration designed for wide-angle lenses.
This lens is distinguished by its fast response focus and extremely quiet, very smooth operation thanks to its built-in SSM (Super Sonic wave Motor).
It offers a wide and therefore highly versatile focal range from 0.19m to infinity, and features a nine-blade circular aperture that along with the large F2 maximum aperture contributes to smooth, natural bokeh effects.
In keeping with traditional Carl Zeiss design, the all-metal lens barrel has been finished to a very high standard resulting in a visibly high-quality appearance.
Sony 24mm f/2 SSM Carl Zeiss Distagon T* SAL24F20Z User Reviews
10 out of 10 points and recommended by Beachrider (22 reviews)Amazing focus performance. Coatings are doing a lot of work on the flare and contrast. Very solid construction.A little heavy. Somewhat pricey.
OK, I gave it all 10s. I would have given a 9.75 on image, if possible. Very usable down to f/2.0, but corners are a little soft at that setting.reviewed August 1st, 2011 (purchased for $1,250)
You need to work really close to subject to exploit semi-macro capabilities.
My first Zeiss. Price for 24mm (f/2) is 70% of price for 24-70 (f/2.8), both from Zeiss. So it is a little pricey.
10 out of 10 points and recommended by edwardkaraa (12 reviews)Excellent sharpness and contrast, Zeiss colors, size, distortion.None.
Very sharp across the frame at all apertures, except at infinity where the very extreme corners need to close down to f/5.6 to sharpen up. Results are simply amazing. Even at f/2 it is as good as it gets.reviewed February 5th, 2011 (purchased for $1,500)
10 out of 10 points and recommended by 3systemuser (19 reviews)sharp in all focus range , very well corrected optics, good AF, very small for what it is.none.
an almost perfect prime for me ,and if you dont need f1.4 or weather sealing of the similar Nikon and the Canon , the Sony is much better lens than these 2.reviewed November 15th, 2010 (purchased for $1,200)
it is much cheaper than both the Nikon and the Canon 24f1.4, it is sharper than both the Nikon and the Canon.
it is much smaller than the both 24f1.4 lenses.
