The Samyang AF 14mm f/2.8 EF is the primary block lens from the corporate to supply an autofocus function for Canon customers. Shridhar Kunte places it to the check.
During the closing 12 months or two, maximum 3rd birthday party lens producers presented 14mm lenses with other mounts. Earlier this 12 months, we reviewed the Sigma 14mm Art lens in Better Photography. In the previous, we’ve got observed Samyang regularly construction a spread of guide focal point lenses principally centered at videographers. Many customers needed for those lenses to be enabled with AF. Samyang responded by means of introducing autofocus first of their Sony mount lenses, and now, for the first actual time, a Canon mount version has been introduced.
This 14mm lens is designed principally for complete body camera customers and helps autofocus operations. Keeping in thoughts the video options on Canon cameras, it makes use of an excessively an identical motor and mechanism that one would come throughout in more recent Canon optics (STM), necessarily to assist video operability. The advantages are smoother, quicker and extra correct focusing.
The optical development is similar to the opposite 14mm lenses present in Samyang’s product vary. It makes use of 15 glass parts organized in 10 teams. There are two aspherical, 4 HR (High Refractive Index) and one ED (Extra Low Dispersion) parts to keep an eye on aberrations. Various part surfaces are specifically lined the use of a number of complicated applied sciences, to verify optimum gentle transmission, and to cut back flare and lack of element led to by means of diffraction.
It is fascinating to understand that Samyang’s Sony mount AF lens and the 14mm guide focal point lens has fewer parts than this lens. I additionally discovered it fascinating to review the minuscule design variations between the basically an identical lenses. There is not any symbol stabilisation serve as to be had in this lens. The electromagnetically managed diaphragm has seven blades. The use of electromagnetic keep an eye on improves publicity accuracy, each for nonetheless pictures and in addition for video, the place the aperture adjustments may also be completely clean.
For checking out the 14mm, I used the Canon EOS 6D for more often than not. The aggregate used to be neatly balanced. This combo seems to be massive and feels really extensive. The lens feels robust and the burden contributes to stability whilst taking pictures. As there is not any integrated IS, this turns into fairly essential. The lens is manufactured from engineering grade plastics and has a steel mount. There is just one ring for focal point (aperture is managed from the camera). Manual focal point is the use of fly-by-wire.
Focusing is performed by means of transferring lens parts internally. This helps to keep the full period of the lens unchanged during the focusing vary. The focusing ring is broad sufficient to carry and has a textured rubber coating. On the lens barrel, there is just one transfer marked ‘A’ and ‘M’.When the lens is within the AF mode, there is not any guide override to be had.
The lens has a bulging entrance part, which prevents filter out attachments fastened on it. Even on the rear finish, there is not any provision for drop-in filters.
The focusing operation is silent and decisively rapid in sunlight. It drops a bit of when the sunshine falls, however accuracy is maintained. There is visual gentle fall-off at broad open apertures. Admittedly, that is one thing that each one ultra-wide-angle lenses be afflicted by. However, chromatic aberrations are neatly managed. The gentle fall-off reduces when the lens is stopped right down to f/4. The lens reveals just right sharpness from f/2.8 to f/11, even if at f/2.8 there’s slight loss in sharpness on the middle and at f/16, diffraction used to be visual.
The edges are comfortable at f/2.8, however from f/4 onwards it improves significantly, hitting the candy spot round f/5.6. Overall, the best possible effects are acquired from f/4 to f/11, a moderately just right vary for a lens of this nature. The lens reveals noticeable barrel distortion, however it may be simply corrected in postprocessing.
Priced at Rs. 53,990, that is probably the most inexpensive ultra-wide 3rd birthday party lens for each Canon full-frame and APS-C DSLR cameras. On APS-C sensors, the lens provides an similar focal period of 21mm. The lens isn’t unduly heavy, and gives a noteworthy optical efficiency. This is a great lens for astrophotographers, and inner and landscapes photographers. Considering that all of the different lenses with a an identical focal period are priced no less than two times as extra, at its degree of high quality, the fee will surely tempt the informal shooter who desires to have a 14mm focal period of their arsenal.
