Laowa STF 105mm f/2 (T/3.2) lens coming soon

Laowa STF 105mm F/2

Thanks to Canon Watch reader mistral75 for sharing this.

After the Laowa 60mm f/2.8 Macro 2:1 and the Laowa 15mm f/4 Shift Macro 1:1 lenses, the Chinese company Anhui Changgeng Optical Technology Company Limited, better known as Venus Optics (see http://www.venuslens.net/about), will announce shortly a new 24×36 lens: the Laowa STF 105mm f/2 (T/3.2).

It is a portrait lens with an apodization filter that gives a more progressive and velvety bokeh than an ordinary lens (STF stands for Smooth Trans Focus). This is the same principle as for the Minolta AF / Sony 135mm f/2.8 [T/4.5] STF and close to that of the Fujinon XF 56mm f/1.2 R APD.

The Laowa has the advantage over the Sony of being one EV brighter. Hereafter its main features:

– 11 elements, including the apodization filter, 1 element made of glass with high refractive index and 3 elements made of low dispersion glass, in 8 groups
– Manual focus (the apodization filter is hostile for phase-detection autofocus)
– Minimum focusing distance: 90cm
– Maximum magnification: 0.16x
– Filter diameter: 67mm
– Dimensions: 76 mm (maximum diameter) x 98.9 mm (length) (depending on lens mount)
– Weight: 745 g (depending on lens mount)
– Available mounts: Canon EF, Nikon F, Pentax K, Sony A and Sony E
– Available in black and silver
– Launch date: January 18, 2016
– Price in China: the equivalent of €500-550 (probably more in Western countries)

 

You can find more details and many pictures taken with the lens on two threads from the Chinese forum Xitek, here and here

A set of full resolution JPG pictures shot with a Canon EOS 5D Mark III can be dowloaded here (password: 9351). You will also find a number of images (pictures of the lens, optical formula, MTF curves and a dozen of sample images as full-resolution jpeg files) in this dedicated Flickr album.
