First Choice for Portrait & Close-up Beauty
Its high speed and the unique aesthetics of its depth of focus make this telephoto lens the first choice for portrait photographers. The angle of view is 27 degrees. It highlights the main body while avoiding the suffocating sense of space compression caused by super telephoto lens.

Smooth Bokeh with Fast F/1.25 Maximum Aperture
Extremely fast f/1.25 maximum aperture affords notable control over depth of field for selective focus shooting, and also benefits handheld shooting in difficult lighting conditions. The smooth transition between the focus object and the bokeh creates a dreamy picture with an ideal depth of field and fascinating background blur.

Customer Reviews
First off, 5 stars for value. Around $800.00 you get a very sturdy and sharp lense. Like everyone else there are some quirks with it. My major thing is the soft corners. Could because I have only used it for a month and haven't come close to perfect my use with it, but there ya go.
Awesome lens with amazing character for medium format!
Terrific lens, covers the sensor and shines with extremely narrow depth of field, which really does separate object from background.
If you are looking for a special lens with main focus on "dreamy looks" and creamy Bokeh you will have plenty of fun with it, as I had (and have). If you are searching for technical perfection don't buy it. With the Hasselblad X1D only to use with electronic shutter with all its drawbacks, but that is not the fault of TTArtisan... For complete review (on german) see: https://www.fotoristretto.ch/muster-beitrag-d-80/
The 1.25 aperture gives paper thin, surreal depth of field. In bright sunlight, you need a strong ND (like 64 or 6) filter to use the lens wide open. With my Hasselblad X2D the lens must be used with digital shutter, and that is extremely slow in reading sensor data (like 300 ms), and that limits the use somewhat. For example, no flash can be used. However, the lens can be used in natural light with somewhat still subjects. Landscape pictures can be shot hand held. Wide open the image is a bit soft. Bokeh is a bit Helios-like.
