Hasselblad XCD 21mm f/4 Announcement

A few significant improvements, compared to the first generation from 2010, can be found in the Canon EF 70-200mm f/4L IS II lens, presented a few days ago.
 
The stabilization system has the efficiency of 5EV and it offers three modes of work: for static shots, for photographing of fast-moving objects and for panning shots. The system is also quieter than its predecessor.

The optical system consists of 20 elements placed in 15 groups, including one fluorite lens and two low-dispersion lenses. The front and rear lens have been covered with fluorite coatings, which help in keeping the lenses clean. In order to minimize light flares and light reflections, Super Spectra Coatings were used. The lens is equipped with an ultrasonic ring autofocus drive – the minimum focus distance is 1m.
 
The lens has the dimensions of 80 × 176mm and it weighs 780g. Canon EF 70-200 mm f/4L IS II is to appear on sale this month and it will cost $1,300.

Fujifilm has just presented a long-awaited medium-format lens - GF 250mm f/4 R LM OIS WR. Apart from the lens, the GF 1.4X TC WR teleconverter and the MCEX-18G WR 18mm and MCEX-45G WR 45mm macro rings have also had their premieres.

Fujinon GF 250mm f/4 R LM OIS WR is a construction consisting of 16 elements placed in 11 groups. Among them we can find two lenses made of ED glass and one made of Super ED glass. The lens has a 9-blade aperture with the maximum light of f/4. With the focal length of 250mm, which is the equivalent of 200mm for full-frame frame, we can expect perfect background blurring. 

The new lens has been equipped with a quiet and quick autofocus and a new mechanism for adjusting the position of the linear motor.  Its minimum focus distance is 1.4 metres. Apart from that, the lens is equipped with the image stabilization with the 5-grade vibration reducing.

Today, Voigtländer presented its latest manual fixed lenses dedicated for full-frame mirrorless Sony cameras Voigtländer Macro APO Lanthar 110mm f/2.5 and Color-Skopar 21mm f/3.5  The first one should especially interest macrography lovers, and the second one - documentalists and street fans. 

Voigtländer Macro APO Lanthar 110mm f/2.5 consists of 14 elements placed in 12 groups. As the producer assures, the designed optical system has been constructed having in mind the latest Sony sensors with high resolution. Apart from that, the lens is to ensure proper resolution, contrast and colours as well as effectively minimize defects, such as chromatic aberration.

The lens is equipped with a 10-blade aperture with the light of f/2.5. Thanks to this, we will be able to get extremely malleable photographs from the minimum distance of 35cm. The filters with the diameter of 58cm can be screwed onto the lens.
