Description

The Argus 25mm is another apochromatic lens in the family of ultra-bright lenses from Venus Optics. The model presented here offers a 0.17:1 reproduction scale and is designed to work with cameras equipped with the Sony E mount. The lens features an APO system that minimises distortion and chromatic aberration. Sharpening from a minimum distance of just 25cm allows you to get as close as possible to the subjects you are photographing or filming. The internal focusing system does not affect the length of the lens when changing settings. The glass also achieves beautiful background blur and soft circular bokeh.

Standard-focal-length

The 25mm on the Sony E system is equivalent to 50mm on full-frame lenses. The glass from Venus Optics will therefore be an ideal “portrait” lens with universal use. The field of view here is 46.7º. This value is close to how we perceive the world with our eyes. It is the best choice for those who specialise in portrait or reportage photography.

Apochromatic design

The apochromatic construction of the lens is designed to achieve the highest possible image quality. The 14 elements are arranged in up to 8 groups. The innovative design includes 1 aspherical glass, 1 ED glass and 3 UHR glass. The use of such advanced optics guarantees detailed, sharp and perfectly framed images with perfect microcontrast. The high quality of the materials also means that chromatic aberration is reduced to an absolute minimum – both in the focus and out-of-focus areas.

Unparalleled brightness

The ability to open the aperture to f/0.95 is ideal for shooting after dark or in areas where sufficient light is hard to come by. It is the ideal choice for a night walk or a session shot at night. The Venus Optics Argus 25mm f/0.95 APO lens for Sony E will not only be appreciated by photographers, but also by video makers. The glass also offers very little ‘breathing’. Thanks to it, the level of instability in the angle of view is reduced to a minimum when changing the focus point during the recording of a shot. Filmmakers can also benefit from stepless aperture adjustment.

Beautiful background blur

The minimum aperture of f/0.95 is also a great way to achieve a shallow depth of field. With this lens, you can easily create beautiful portraits with a blurred background or highlight the main subject of a photo. The icing on the cake is the smooth and rounded bokeh with no sharp edges that you get with the 9-blade aperture.

Internal focusing system

The Internal Focusing technology used in the Venus Optics Argus 25 mm f/0.95 APO lens for Sony E means that all lens movements take place inside the housing. Changing the focus therefore does not affect the length of the unit. This ensures optimum stability and even greater comfort. This solution is sure to be appreciated by those using filters, sun hoods or other accessories that are screwed onto the lens. Internal Focusing also provides better protection for the glass against dust. Dirt is more difficult to get at, compared to designs offering ‘external focusing’.
