Yongnuo YN 50mm f/1.8 II Announcement

New manual Samyang MF 85mm f/1.8 ED UMC CS lens with the equivalent of 135mm is dedicated to the users of cameras with the APS-C sensor, namely: Sony E, Fujifilm X and Canon EOS M.
 
The optical system of the lens consists of nine elements placed in seven groups. Among them we will find one lens with high refractive index and one low-dispersion lens. Covering the lenses with UMC coatings should minimize light reflections and chromatic aberration. The producer assures that new Samyang is to ensure high resolution within the whole frame as well as good contrast and color reproduction.

The lens is fully manual, which means that the control is provided by physical rings which regulate aperture and sharpness. Depending on the camera's system on which we are going to mount the lens, its equivalence will be 127 to 136mm. Sharp photographs with the use of the lens can taken from the distance of 65cm, the aperture consists of nine blades and the filters with the diameter of 62mm can be mounted on the front lens. The lens is not big since it's only 8cm in length and it weighs 344g. 
 
New Samyang will be available on sale at the beginning of September and it will cost $399.

Yesterday's premiere of Nikons Z6 and Z7 with the new ”Z” mount standard had to entail the presentation of the dedicated lenses. Today we're going to briefly discuss three of them: Nikkor Z 24-70mm f/4 S, 50mm f/1.8 S and 35mm f/1.8.
 
The three presented lenses are to satisfy basic standard needs of photographers. They are supposed to be characterized by high quality of the optical system and they are to be quiet, without the focus breathing effect. The detailed specifications are not known yet.

 
Nikkor Z 24-70mm f/4 S
The optical construction of the lens consists of fourteen elements placed in eleven groups. One low-dispersion lens, one aspherical ED lens and three standard apsherical lenses have been applied in it. The lens is to ensure brilliant resolution within the whole frame, even at maximum aperture. What's more, it is also to remarkably deal with chromatic aberration. In order to avoid light leaks and flares, the nanocrystalline coatings have been used. The fluorine coating which covers the front lens is to facilitate keeping it clean.

Sharp photographs with the use of Nikkor Z 24-70 mm f/4 S will be made from the distance of 30cm within the whole focal length.
Price: $999.

 
Nikkor Z 35mm f/1.8 S
The optical cosntruction of the lens consists of two low-dispersion (ED) lenses and three aspherical lenses. Similarly to the first lens described today, we can expect remarkable sharpness within the whole frame. According to the producer, this effect should bring the impression of “changing the way f/1.8 lenses will be perceived.” Thanks to reducing chromatic aberration, among other things, the lens is to perfectly fulfil its function while photographing point light sources at night and obtaining “soft and natural blurring” should not be a problem.

Nanocrystalline anti-reflective coatings have been used on the lenses and the AF is supposed to be as quick, quiet and precise as never before. The whole construction has been additionally protected against dust and splashes.
Price: $949

 
Nikkor Z 50mm f/1.8 S
The optical system of the last of the lenses described today consist of two ED lenses and two aspherical ones. Similarly to the constructions discussed above, we can expect high resolution within the whole frame. This time in the description the producer mentions extraordinary benefits of reducing longitudinal aberration, exceptional mapping of tiny textures at maximum aperture and, again, high image resolution.
 

3). Nikon Nikkor Z 50mm f/1.8 S
 
Similarly to the above lenses, this one also applies nanocrystalline coatings and is reistant to splashes and dust. The advanced stepper motor construction is supposed to ensure quick, quiet and precise AF, both during photographing and recording films.
Price: $600

 
During the presentation of the lenses described today, the graphics showing further steps of the company with regard to the premieres of “Z” standard lenses in the next three years was presented. In 2019, three new lenses, headed by the extraordinarily bright Nikkor Z 58mm f/0.95 S Noct, will appear on the market.

5). Nikon Nikkor Z Lens Roadmap
 

Yongnuo is not wasting time - the YN 35mm lens described today is the fourth lens of the producer about which we are informing this year.  The main properties of  the lens concern the complex optical system with the advanced defect correction, good resolution,  effective autofocus and resistant body. This bright full-frame camera may become an interesting proposition for the fans of street, reportage or even portrait photography.
 
The optical system of the lens is based on 11 elements placed in 9 groups - among them we will find two aspherical lenses and two low-dispersion ones. Yet another procedure used by the producer in order to minimize the appearance of the light flares and light leaks is covering the lenses with several anti-reflective coatings. The aperture of the lens consists of 7 blades and its nominal hole is f/1.4. The minimum focus distance is 35cm.

The effective DC Motor is responsible for the speed of work of the autofocus. Thanks to it, the AF is to be quick, precise and it should work well even in the "Live View" mode. On the body of the lens, we will find a frame which facilitates manual focusing and which shows the scale of the hyperfocal distance. Thanks to the USB connection, it will be possible to update the lens' software.

Yongnuo YN 35mm f/1.4 is equipped with gold-plated contacts and the metal mount has been covered with the chrome layer. All of this is supposed to positively influence electrical conductivity and general durability of the lens. The device has the dimensions of 82 × 111mm and it weighs 810g.
 
The detailed specification of the lens is not known yet. Unfortunately, we also don't know when YN 35mm f/1.4 will appear on sale and how much it will cost.
