Large f / 1.2 aperture with excellent light transmission
Good size and weight to a small mirrorless body compliment
Good physical and mechanical construction
portrait good option
chromatic aberrations are relatively low
Good (and strong) bokeh 9 bladed aperture to be circular and also produce great sunbursts
large resolution even at wide hole
a strong contrast
Vignette and fairly well controlled distortion
Including lens hood and drawstring bag for lens

-(-):
Manual focus only
There is no electronic coupling means no EXIF data is a lens or lens profile
Slightly more expensive than many of the Samyang lens / Rokinon
The need to change the settings in the camera to create a lens properly function - creating confusion for some users. (source: http://www.canonrumors.com/reviews/review-samyang-rokinon-50mm-f1-2-as-umc/)

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.

Specifications
Optical construction 9 elements in 7 groups inc. 1x aspherical element
Number of aperture blades 8 (non-circular)
min. focus distance 1m (max. magnification ratio ~1:9.5)
Dimensions 78x72mm
Weight 513g
Filter size 72mm (non-rotating)
Hood barrel-shaped, bayonet mount, supplied

Samyang 8mm f/3.5 Fisheye Review



Samyang 8mm f/3.5 Fisheye Review. Samyang Optics (Korea) offers the DSLR lenses for many years, but recently have had a visibility a little 'and the popularity of some very exciting new products, such as the recently revised Samyang 85mm f/1.4, Samyang 8mm f/3.5 Fisheye cover that in this test. Samyang lenses are marketed by many companies, such as Vivitar (7 mm f/3.5), Bower (8mm f/3.5) Optek (6.5 mm f/3.5), walimex (8mm f/3.5), and probably a couple more.


To date, Samyang lenses do not have all the electronics so while you will be able to mount these lenses without an adapter, you will have to live without autofocus and a camera control opening. The 8 mm f/3.5 lens Samyang is a dedicated full-frame fisheye for APS-C DSLR. You can also get in a long format (35 mm) DSLR, but the accumulation of sunscreen will be visible in the image, in this case. Typical fisheye lens field of view is enormous - 180 degrees or more precisely: 167 degrees on Canon EOS digital SLR APS-C format (1.6 times the harvest instead of 1.5 x) - then One of the barriers to using this type of lens is to prevent your feet from the scene.

Fisheye lens is not unusual in itself so you might ask, why bother to check the lens rather "exotic" by the manufacturer. Well, fisheye lenses are usually not cheap. Even the Sigma asking up to $ 900US / Tokina fisheye zoom 800EUR and sells about $ 500EUR/600US. Samyang falls below $ 280EUR/360US!

If you think this lens has a sloppy build quality, affordable ... Therefore, be prepared for a surprise - it's very good. The main body is made of metal and a rubber ring approach works smoothly and is being amortized in the good old days. Rings (plastic) of the opening feels a bit less robust, but works fine with distinctive "clicks". The bulb of elements in the front, it is impossible to filter, but it is normal for this type of lens. It's a little "uncomfortable" to fix the front cover, but it is certainly a good idea to take the opportunity to protect the lens during transport. The physical length of the lens is almost constant - it moves slightly (0.5-1mm) in focus.

The lack of autofocus can be a bit difficult to Samyang 85mm f/1.4, but is essentially a fisheye 8 mm f/3.5 is not afraid because of the large depth of field provided by such purpose - to most scenes by adjusting the focal length of 2 meters and be happy forever. In case of doubt (for example, in situations of interest very close), of course, you can use Live View to refine the focus manually. Aperture (work) directly into the lens can also be something to get used to, but in reality is a compromise here.

This is a sample image taken by the Samyang 8mm f/3.5 Fisheye lens
