Samyang 85 f/1.4 Review



Samyang 85 f/1.4 Review. We looked at f/1.4 Aspherical Samyang 85 mm per year, then a DSLR in full size, but because of the popularity of the lens does not really want to skip the analysis of the APS-C size range.

Samyang is a Korean company that manufactures a wide range of lenses very affordable. Until a few years ago, they covered the low-end market, but they move slowly up the value chain is now very competitive with glasses and unusual as a fisheye 8 mm f/3.5, 14mm f/2.8 an ultra wide angle the f / 1.4 85mm and mentioned with effect from the time of this study, they are about to send their brand new 35mm f/1.4. Samyang lenses are also sold by other companies such as Vivitar, walimex, Optek and probably a little more. This alone may not be too special, but an ultra-wide 85mm lens f/1.4 Aperture sold for about $ 300-300EUR/US is almost a sensation.


At the first contact had two immediate damage - the lens does not offer the AF, or switch 'native' also compatible with Canon EF Mount - in other words, does not require an adapter, but that's all. Illustration of the product below shows the rear view of the lens - you may find that the electrical contacts. So you need to focus manually - is the image in the viewfinder, or probably a better idea of ​​possible much depth of field, using Live View. Aperture does not control the camera directly, but through the lens aperture ring, the old as new. The camera is, of course, be able to view the opening selected as the viewfinder as well as EXIF ​​data visible only to f/0.0 here. Aperture is also stop when you change the setting so that it appears darker than the optical viewfinder aperture settings smaller image.

Now, in addition to these deficiencies - what do you get to a couple of dollars? Well, surprise, ... a lot '! The build quality is nothing short of excellent, thanks to a combination of high quality metal and plastic parts - the goal set many of the genuine manufacturer of shame in this reality. Has no oscillation. Focus is smooth as silk (wet) and the aperture ring is distinctive clicks 1/2EV steps (except f/1.4-> f / 2 ef/16- f/22>). The lens has an internal focusing (IF) mechanism, so the physical size remains constant during focusing and a large front-end does not rotate.
