With ever-improving technology, mobile photography is quickly catching up. We believe that the future of photography is in your pocket. The best camera is the one you have with you, and that camera is your phone. YeeChan has created a Depth of Field（DOF） lens specifically designed for Smartphone: the 50 mm  F/1.7  Capture vibrant image quality, superb bokeh, shallow depth-of-field and film-style look and the ability to pull focus manually like on professional cinema cameras. 

The F/1.7 aperture lets more light into the lens, which could effectively reduce the ISO sensitivity and obtain a low-noise transparent to improve your image quality. The circular aperture formed by 11 aperture blades  bring a large foreground and background blur, make the subject more prominent, and can bring a soft picture effect. So you can comfortably shoot in low-light, complex environment or night conditions.

Achieve the perfect portrait with the 50 mm  F/1.7 provided by YeeChan lens, highlighting your subject’s features with shallow depth of field to create an intimate visual perspective.

Superb optical performance and beautiful background blur effects

Setting a new trend for mirrorless.

Vibrant images with soft, defocused blur qualities.

Pursuing an unprecedented balance of image quality, light weight and compact size.

 The 50 mm focal length has a field of view close to what the human eye sees, and can be used for composition shooting with a more familiar visual experience. Although imaging does not have the distinctive personality of wide-angle or telephoto lenses, as long as you actively adjust the distance to the subject to change the composition, you can also get refreshing effects. It is precisely because of this that the 50 mm focal length can be adapted to shooting in a wide range of fields such as portraits, street photography, scenery, pets, and food.

YeeChan uses a durable alloy bayonet and the matte metal silver design is used on manual aperture  the with the camera, it looks magnificent and has a high degree of recognition.

The optical structure of the YeeChan is 11 elements in 11 groups. YeeChan also uses multi-layer coating with good anti-reflection effect, which can increase the transmittance of the lens, effectively suppress the glare and ghost caused by the light source in the picture, and reduce the influence of backlight on imaging. Brings a clear and transparent photo effect.

The Minimum Focusing Distance of the lens has been shortened to about 0.15-0.2 meters. You can get closer to the subject during shooting, and take small objects larger to achieve a macro-like effect. Coupled with the natural perspective of the 50 mm standard lens, it can provide an effect close to the human visual experience, which is very suitable for shooting food, snacks, small objects and commodities.

Because it is designed to be your most frequently used lens, we made it compact. Now you can enjoy advanced optical performance in a compact size  with a total length of only about 119 mm （4.7in）and a weight of only about  360g. It is good to take it with you when you go out, or hold it for a long time, which contributes to the stability of shooting. Making it easier to use.

YeeChan allowing videographers to make smooth aperture changes while retaining traditional aperture stop for stills photographers. The manual focus ring is incredibly smooth and perfectly damped, allowing for smooth and accurate focus results across the 180 degrees of focus travel.

In order to solve the mechanical challenge of the precise bayonet interface with the space constraints around the iPhone camera. YeeChan employs a threaded connection for a firm, easy to use the connection.

The Moisture-Resistant and dust-proof structure is adopted, and the bayonet, focus ring, switch panel and switch of the lens are sealed to improve the reliability of the lens. In addition, by improving the strength of the lens barrel and redesigning the structure of the part connection, a highly robust lens body structure is realized without increasing the weight as much as possible.

YeeChan compatible with iPhone X and above and Samsung Galaxy S10/S10+ /S20/ S20+.

The YeeChan lens projects the image upside down. For this reason, we recommend using a third-party app to flip the image back to the normal orientation, such as FiLMiC Pro (Video – iOS and Android), ProCamera (Photo and Video – iOS), Filmakr (Video – iOS), MAVIS (Video – iOS), ProMovie (Video – iOS), Camera 645 Pro Mk 3 (Photo and Video – iOS) or Open Camera (Photo/Video – Android). 

You can also use the YeeChan in your smartphone’s stock/native camera app with the image flipped upside down if you prefer.
