Review Zeiss Loxia 25mm f/2.4
The Zeiss Loxia f/2.4 25mm is a wide-angle lens for the Sony cameras with E-mount. It is compact and reasonably bright. Just like the other Loxia lenses, it does not have autofocus. On the other hand, the Loxias have a perfect, fully linear manual focus that gives you complete control as a photographer and is also excellent if you want to film with these lenses. And - as we have come to expect from the Loxias - the image quality is extraordinary.
Top quality for film and video: Zeiss Loxia 2.4/25mm
The Zeiss Loxia f/2.4 25mm is a 25mm wide angle with a maximum brightness of f/2.4. It fits all Sony cameras with an E-mount. That means on the full-frame A7 and A9 models as well as on the APS-C cameras such as the A6400 and A6500. On the APS-C models, this lens works as a light-wide-angle standard lens. This lens comes into its own most naturally on the full-frame cameras that allow you to utilize the full angle of the Zeiss Loxia f/2.4 25mm. The Loxia is compactly built using high-quality materials. The lens is solid in your hand and breathes quality. It has no autofocus, but at the same time, that is one of the reasons for choosing a Loxia. All lenses from this series have beautiful, smooth and linear manual focus with hard stops. The aperture can also be made clickless, making the Loxias not only ideal for lovers of classic photography, but also for enthusiastic film makers.
BUILD AND FOCUS
The Zeiss Loxia 25 mm f/2.4 is - just like the other Loxias - pretty compact. It has the exact same diameter as the other four Loxia lenses. That not only looks good but is also especially useful for videographers who use these lenses in a rig with a follow focus. Because the diameter of the lenses is the same, they can easily be changed without changing the follow-focus setting. It is also useful for photographers who like to use filters. All Loxias namely have the same 52mm filter size. The lens is made entirely of metal and glass, and you feel that you are holding something solid in your hands. The lens hood is also nice and compact and can be mounted backwards on the lens for transport. The focus ring has fine grooves that ensure a good grip. The ring itself turns nice and smoothly and has hard stops at close range and infinity so that you never turn further than necessary and so that you can set to infinity in the dark for example. The aperture ring clicks in at 1/3rd stops if desired, or it will turn completely clickless for infinitely variable adjustment during filming. You choose this by turning a screw on the mount with a small key that is included. You can also see the set value displayed without clicks in the viewfinder of your camera. The lens also has a depth of field indication between the aperture ring and the focus ring. At the rear is a thick gasket to properly seal the connection to the mount. That gasket is so thick that you really have to put a little bit of force into changing the lens. And that is actually the only thing that is not great about the Loxia lenses. Changing lenses is a bit tricky. That is a small minus, but not unimportant because you will probably change lenses with fixed focal points more often than zoom lenses. That it is somewhat difficult is because both the aperture ring and the focus ring turn. The ring in between, the one with the depth-of-field indication on it, does not, and that is where you actually have to grab the lens to change it. But that ring is very thin and also has little grip. In practice, you often have to first turn the aperture ring to one of its extreme points before the lens itself will turn. As a result, the turn required to change a lens is much greater than necessary. If Zeiss had made the non-rotating part slightly larger, or slightly thicker in diameter, preferably with a good serrated edge on it, then this problem would not exist. But that would of course detract from the minimalist design.
