From the editor
A Chinese clone of the Meyer-Optik Gorlitz Trioplan 100/2.8. Like the original, it is bought by most photography enthusiasts because of its dreamy background blur with so-called soap bubble bokeh, which is characterized by sharp-edged out-of-focus highlights. To achieve this effect, take pictures with the aperture fully open, focus at short distances, and the background should be as far away from the subject as possible. The shorter the focusing distance, the larger the out-of-focus highlights will be.
It should be noted that modern portrait lenses are designed to provide smooth Gaussian blur and even out-of-focus highlights at portrait focusing distances. If this is the kind of bokeh you need, the TTArtisan 100/2.8 is not for you, and you'd better look at some other models.
For such an optically simple lens consisting of 3 uncemented elements, the TTArtisan 100/2.8 is heavy at 387g. The reason is that the lens barrel is made entirely of anodized aluminum. In principle, this lens belongs to amateur models, and users would understand if the lens barrel - and maybe even the optical system! - were abundantly plastic. The manufacturer was probably bound by the canon that "requires" that all retro-style lenses and/or lenses designed for the LEICA M rangefinder cameras be made of metal.
The lens accepts 52mm screw-in filters, while a lens hood is not available. The screw-on front cap may be inconvenient for some people because it takes a few seconds to unscrew, which can lead to missing a decisive moment. Why this lens could not be provided with a conventional snap-on cap remains unclear.
The lens was also produced in version with the M42 screw mount.
