The Samyang 85mm T1.5 is a manual focus
prime lens, this VDSLR (Video DSLR) version has been developed primarily
for professional cine / movie making purposes. The VDSLR version
feature follow focus gearing and decoupled aperture, which allow the
user to smoothly and quietly change focus and aperture / depth of field
whist filming, and link to professional follow focus cam systems.
Samyang 85mm T1.5 is a manual focus prime lens, designed to give
exceptional results at wide apertures. At T1.5 great images can be
obtained, which is perfect for portraiture and low light shooting,
particularly when mounted on a full frame DSLRs.
VDSLR Cine lenses are rated in T-Stops rather than F-stops which is the
standard for professional movie camera lenses. F-stop number expresses
the speed of the lens on the assumption that lens transmits 100% of the
incident light, and therefore is theoretical rather than a real world
measurement. The T-number expresses the actual light transmission, and
thus is accurate for exposure purposes. It is also worth noting that the
Samyang lenses achieve excellent transmissions properties.
bokeh (the character of the out-of-focus blur) is a primary concern for
professionals choosing an ultra large aperture lens for shallow
depth-of-field photography. The Samyang 85mm T1.5 lens design offers
excellent bokeh quality of out-of-focus highlights when used near wide
open, perfect for film and cine applications. Independent tests and
users confirm the Samyang's beautiful bokeh character, surpassing lenses
4 times the price.
The lens optical construction is the same as
the 85mm f1.4 lens comprising of 9 lenses divided into 7 optical groups
with one aspheric lens element. The Samyang 85mm is designed with
internal focusing (IF) meaning the lens does not increase in size when
focusing. A further positive aspect to internal focusing is that the
lens is much less likely to get dust inside, as opposed to external
focusing (or zooming) lenses which can suck in dirt during use. The 8
bladed aperture design aids a great bokeh character at near wide open
The Samyang 85mm T1.5 IF MC features Multi-coated
lenses which aid the very high level of light transmission, and added
resistance to flare and ghosting. It features a good sized manual focus
ring and is perfectly adapted to most photographic applications
(exclusive of sports or fast moving subjects) where manual focus is not
an issue. Accurate for focus critical situations can be achieved through
use of focusing in live view mode, available to most newer camera
models. In practice users including professional photographers have
found manual focus of the Samyang 85mm not to be an issue, even shooting
at f1.4 with a very shallow depth of field in low light scenarios with
static and slow moving subjects accurate focus can be achieved giving
excellent results thought the image on full frame cameras.
are also increasing numbers of users using DSLRs for filming and High
Definition (HD) video and manual focus lenses allows the user to alter
focus during filming, and hence why the VDSLR versions were developed.
focus ring features toothed rings compatible with professional geared
follow focus systems available in the film industry and likewise a
toothed, decoupled (de-clicked) aperture ring. Such modifications allow
for smooth and precise control over focus and aperture during video
recording / filming. This allows for ultimate manual control of focus
and exposure when filming from one scene to another with different light
source intensities, such as changing exposure values (EVs) from inside
to outside, or even in-camera fade ins etc.
The Samyang VDSLR
versions can be used in still photography as well as for video purposes.
There are increasing numbers of users using DSLRs for filming and High
Definition (HD) video and manual lenses allows the user to change focus
(focus pulling) and aperture during filming.
The Samyang 85mm T1.5 lens should be a serious consideration to
all professional or amateur photographers requiring a fast prime lens,
regardless of budget. When the low cost of the lens is considered it
should not be overlooked for amateur use, or as a primary or secondary
lens for professionals wanting a dedicated, high performing T1.5
