For many years, Carl Zeiss is world-famous for producing top quality lenses, especially the manual focus lens. In recent years, Zeiss has gone to great lengths to improve on their manufacturing skills in electronic and digital technology, and has been producing many new lens that have received very good feedback on their quality. One stellar example was in 2015, when Zeiss introduced the Batis 25mm f2 and the Batis 85mm f1.8. These lens are now highly sought after by many professional photographers as well as hobbyists worldwide. Last month I was invited to attend the opening of the Mandiri JOG/ART/9 event and also SAPIENS FREE by the OHD Museum group in Jogjakarta, Indonesia. I was also invited to visit all the other 4 private museums by their owner, Dr OHD, who is among the biggest private collector of Indonesian arts by the Indonesia Grandmaster artists, in the world. Zeiss usually gives a different brand name for each different camera producer. For the Sony E-mount (35mm format), the branding is Loxia for the manual focus lens and Batis for the autofocus full frame lens. Since the beginning of 2016, Zeiss has announced the launch of the Batis 18mm F2.8, and now it has a very long waiting list of buyers waiting to get hold of this lens. Last month I was invited to attend the opening of the Mandiri JOG/ART/9 event and also SAPIENS FREE by the OHD Museum group in Jogjakarta, Indonesia. I was also invited to visit all the other 4 private museums by their owner, Dr OHD, who is among the biggest private collector of Indonesian arts by the Indonesia Grandmaster artists, in the world. Through sheer luck, Mr Denis Lim, the senior sales manager of Shriro Singapore Pte Ltd managed to get hold of a unit of the Batis 18mm F2.8 for me to use. I then conducted a user preview of this wonderful lens during my short trip to Jogjakarta. Personally I would classify super wide-lens as those wider than 21mm, and are usually reserved for landscape, astro and architectural photography. My personal collection consists of the M21mm Elmarit for my M9, EF16-35mm F4 for my A7R, and the M.zuiko 7-14mm F2.8 for my Olympus OMD10Mk2. My favourite is the M21mm but on many occasions it was always not wide enough for my subjects and my shooting style. The M.zuiko is very good and reliable but the OMD10 is not my serious camera. I have been waiting for a good super wide lens to use it on my A7R and I think this Batis 18mm is the best I can find in the market after using it for only a few days. My shooting style is mostly wide and I find that the 18mm is perfect for me when I need to bring only 1+1 lens. The very large field angle of this super wide-angle lens is perfect for creative shots with unusual perspectives too. Briefly, the specifications of the Batis 18mm fullframe autofocus E-mount lens are: · Aperture range: f2.8 to f22 · Focusing range: 25cm (about 9.8) - infinity · Filter diameter: 77mm · Field of view: 99° (diagonally) · Number of Aperture blades: 9 (rounded) · Elements/Groups: 11/10 · Weather sealing · OLED screen display · Weight: 330gsm The first thing you will notice when you see the lens is its size ..BIG and intimidating, and when you first hold it, you will be surprised with the weight........its LIGHT. Though you can feel that the whole lens body is made mostly with plastic materials, you can also feel that it is well made, and the design flow is smooth and modern.
