[REVIEW] Samyang 14mm AF Nikon Mount - MASTER: THE ART OF 14mm - Francesca Dani

Pubblicato il: 2 Settembre 2018

I am happy to announce I had a sponsorship collaboration with Samyang Optics, who kindly sent me their new lens released few days ago to test it: the brand new 14mm AF Nikon. Happy I was the first in Europe to test their new 14 in AF on Nikon mount. :-) 

I previously owned the 14mm MF and those who already own the MF lens will "feel" the difference if you'll switch to the next level acquiring the new AF. 

Samyang announced in the middle of July 2018, the brand new Samyang 14mm f/2.8 Nikon AF: the company’s 8th autofocus lens and the company’s first-ever autofocus lens for Nikon DSLR FULL-FRAME cameras. 
This lens offers faster, accurate and also quieter auto focus performance. The lens also features weather-sealing and a AF/MF switch for its usability. Design is also changed a bit from the older MF version: the brand new one is more classy with a minimal design, with a nicely-smooth shape that is very pleasant to hold and use, the lens appears nicely made and I love the looks. I can surely claim to be a fan of the aesthetics of the red ring and shiny smooth black finish. 

DESIGN COMPARISION:

With a minimum focal length of only 0.20m, it is possible to capture more vivid close-up images of portraits, pets, food, indoor and etc. anytime, anywhere. The virtually-identical Canon EF version of this lens was announced back in January 2018, and it was the company’s first AF lens for Canon EF-mount cameras. The Samyang 14mm f/2.8 is a wide-angle prime lens that’s designed specifically for use on Nikon FULL-FRAME cameras, but it can also serve as a 21mm-equivalent lens when used on a Nikon APS-C (i.e. DX) camera.

🔸 PACKAGING, HOODS AND HOW IT FITS ON MY D810:

🔸 FEATURES

- 116.6° ULTRA WIDE ANGLE: Ultra-wide angle allows to capture the creative space beyond what meets the eye and portray an expanded sense of dimension.

- CRYSTAL CLEAR RESOLUTION: Take pictures with incredible sharpness and accuracy with the Samyang’s world-class optical technology.

- UPGRADED FAST, ACCURATE AND QUIET AUTOFOCUS: Samyang’s advanced technology upgraded its Auto Focus system and it offers more faster, accurate and quieter auto focus performance.

- WEATHER SEALING: For more stable shooting and extended lifecycle, it provides maximum protection for the lens: camera protection against dust and moisture.

* HOW TO READ A "MTF" CHART: There are two groups of data plotted on a Nikon MTF chart: Sagital and Meridonial lines. "Sagital lines" (the solid lines) represent the contrast measurements of pairs of lines that run parallel to a central diagonal line that passes through the middle of the lens from the bottom left hand corner to the top right hand corner. "Meridonial lines" (the light lines) represent line pairs also positioned along an imaginary line from the center of a lens to the edge but these line pairs are perpendicular to the diagonal line. There are two groups of test lines for each Sagital and Meridonial value: one group or line pairs at 10 lines per millimeter and a second group at 30 lines per millimeter. The lower line pairs (10 lines/mm) will generally be plotted higher on the graph than the more challenging fine resolution 30 lines/mm. In general, the higher and flatter the lines the better. Higher lines indicate better contrast (10 lines/mm) or resolution (30 lines/mm) while a flatter  line shows that the optical performance is close to the same at the edge of the image compared to the center. 


* USING THE MTF CHART ABOVE TO DETERMINE THE "BOKEH" EFFECT OF THE LENS: 
Another factor that can be read from the MTF graph is the 'bokeh' of the lens. Bokeh is a term used to describe the quality of the out of focus areas a lens produces. The bokeh effect varies between lenses and the effect is influenced by the quality of the lens elements used and the number of aperture blades in the lens design (more blades produce a better circle and therefore a better 'bokeh' effect). The closer the solid line and the light line are together, the softer the out of focus effect will be on a particular lens.


🔸 CONCLUSION:
Samyang 14mm f/2.8 AF Nikon Mount represents excellent value for money to anyone (Nikon users) on the lookout for a fast ultra wide angle camera lens. It should be on the market EU in September 2018 and those who wish to shoot wide angle photos in movement, should take a look at this brand new jewel. It's not a lens-based optical image stabilizer.
The 14mm focal length can, especially with the interesting perspective it provides, capture artistic types of imagery. Take advantage of perspective distortion by moving in close to make something appear huge in relation to its surroundings. The success of a lens is often directly related to the image quality it delivers and sharpness, a combination of resolution and contrast, is the most important image quality attribute for most. I'm happy to say that the Samyang AF 14mm f/2.8 Nikon Mount Lens delivered great results in this test.
