## Overview

The Samyang 135mm F1.8 AF is a premium full-frame telephoto prime lens designed for Sony E-mount cameras, offering a bright F1.8 aperture, ultra-sharp optics with 13 elements including UA and ED glass, and an 11-blade diaphragm for smooth bokeh. It features fast, quiet autofocus with a Linear STM motor, customizable controls including a Focus Hold button and aperture adjustment via a custom switch, and a Focus Range Limiter for optimized AF performance. Weather-sealed and built for professional use, it excels in portraits, astrophotography, and video, delivering exceptional corner-to-corner sharpness and reliable operation in diverse shooting conditions.

## Description

The new AF 135mm F1.8 E telephoto lens is optimised for portraits, astrophotography, landscapes and video shooting. It includes Samyang's key features, such as: focus lock button, custom switch, and focus range limiter switch. With Samyang's announcement of the new AF 135mm F1.8 E, its Auto Focus F1.8 E series now includes: 24mm, 35mm, 45mm, 75mm and 135mm focal lengths, completing the lineup from wide-angle to telephoto. AF 135mm F1.8 FE Key Features Superb Resolution Unsparing application of Samyang's most advanced optical technologies has produced a large-aperture prime telephoto lens that delivers outstanding corner-to-corner resolution. The AF 135mm F1.8 FE delivers an 18.9˚ angle of view for full-frame and 12.5˚ for APS-C. It features a bright maximum aperture of F1.8 throughout the entire image, as favoured by full-frame camera users. In particular, optimum resolution is achieved through the optical design of 13 elements in 11 groups (1 U-ASP, 2 HR and 3 ED). Combined with Sony's full-frame image sensor, this lens delivers superior sharpness and contrast in all areas of the image. Able to deliver extremely narrow depth of field, with beautiful bokeh The AF 135mm F1.8 FE uses a large-diameter aperture to provide smooth background blur. It effectively allows separation of the subject from the background, by using a shallow depth of field. Also, it is equipped with a UA (Ultra-precision Aspherical) lens, which delivers natural and refined bokeh. Using this smooth bokeh, you can freely create images highlighting your subjects against stunning backgrounds, whether shooting portraits, close-ups or even cityscapes. Fast and Quiet Auto Focus Performance Tracking the subject accurately and quickly, the AF also operates quietly and smoothly when shooting video. Samyang's Linear STM (Stepping Motor) satisfies both photographers and videographers with quieter and more accurate control of the focusing lens groups. Enhanced Operability and Reliability Important features include customisable: A Focus Hold button, Custom Switch and Focus Range Limiter. Overall, this is a lens that meets or exceeds professional requirement for control and reliability for both stills and movies. 1) Focus Hold Button Pressing this button on the lens will keep the lens locked to that focusing distance. You can assign functions such as Eye AF in settings on the camera body. 2) Custom Switch There is a custom switch, which can be set to allow adjustment of the aperture silently by rotating the focus ring. Using the optional Lens Station, you can set up the mode to suit your own preference. (More functions will be added through firmware updates in the future.) 3) Focus Range Limiter switch The Focus Range Limiter only operates in AF mode. It is useful when the distance from an object has been determined. Move the Focus Range Limiter forward or backward to select the focus range. - FULL: The AF range is set to infinity at a minimum focus distance of 0.69m. (AF search may take slightly longer.) - 0.69m - 2m: The AF range is set between 0.69m and 2m, which is suitable for close-up shooting. - 1.5m - ∞: The AF range is set from 1.5m to infinity, which is suitable for normal shooting. Short minimum focal distance of 0.69m Although this is a 135mm telephoto lens that effectively controls aberration at all focusing distances, Samyang has made it possible to achieve a minimum focus distance of just 69cm (2.26ft) and a maximum magnification of 0.243x for close-up photography. Small accessories and other subjects can be captured with remarkable resolution and beautiful, soft background bokeh. Modern design and weather-sealing The AF 135mm F1.8 FE has been developed and enhanced, taking into consideration not only the design features but also the user's shooting environment. It has a micro-patterned rubber focus ring, which feels great to operate and the weather-sealing protects the lens from light rain, snow and dust.

Review: An amazing lens! - Very sharp and fast for still photography. I love the creamy bokeh it produces. Other than the price it's perfect lens for my needs. I'm using it with my APS-C Sony ZV-E10 camera and there is no vignetting or lack of sharpness in corners as my camera has crop sensor.
Review: Excellent, as sharp as Sony version - Read my warning and solution about firmware update at the end of this review!!! This is my dream lens. I owned the manual focus Samyang 135 f/2 version previously (Nikon F mount), I loved it was my number one lens for shooting portraits and sometimes for astrophotography. I used it for a while after switching to Sony, sold it with plans of buying the Sony version. As soon as the Samyang 135 f/1.8 came out I knew that it was going to be very sharp, and I was hoping it to be as sharp as Sony version. Reviews approved it to be. Packaging The lens is appropriately packaged. There is a lens pouch in the box which I never use. Build Quality The build quality is excellent, nothing feels cheap about it. Previously I used the Samyang XP series 85 f/1.2 and XP 14 f/2.4 lenses. This one has a similar feeling. Lens Hood & Cap The hood is thick and gives a very sturdy feeling and it has a softer part on the very tip, so you feel that nothing is going to chip-off when you hit it somewhere accidentally. The lens cap is a little thicker then most of my Sony lenses, that's the only negative comment I can do about the build quality. Weight The 772 gr weight is appropriate for this kind of lens and the weight is properly distributed to the lens. I feel the body with the lens is balanced properly (not front heavy that is). The center-of-gravity is around the metallic ring which is right in the middle of the lens. Focus Ring It is super smooth, and very precise, it is not linear but there is not too much difference between rotating the ring very fast or very slow. I tried manually focusing to the moon and I'm very surprised that the ring allows doing very very fine adjustments. I'm very satisfied with it. Buttons The single button and the two switches on the body are appropriately placed. Though, I would say the placement of the single button is not matching with my other Sony lenses, so it kind of breaks your muscle memory. But, again it is totally in a comfortably reachable position. The button has a different feeling then the Sony lenses and the pressed distance is somewhat shorter than the Sony lenses which reduces the feedback when pressed. But I'm knit picking here, it is totally fine. Autofocus The autofocus is excellently fast. I don't have the Sony 135 f/1.8, but the reviews I watched confirms that there are no difference between the Sony and Samyang versions. I'm very satisfied with the auto focus on my Sony A7R IV. No complains there. Tested going from 1m to infinity consequently and it is super fast. Focusing on darker conditions is also appropriately successful, though your keeper rate naturally will be reduced. Focus Breathing It is very interesting, the lens reverse breaths. In the closest focus distance, the focal length is probably higher than 135 mm (thinking the focal length of a lens is measured when it is focused to infinity). Because the frame gets narrower, the lens zooms in a little that is. When you focus towards the infinity, the lens becomes wider. But, again, the focal length of a lens is measured when the lens is focused to infinity. So in closest distance the focal length of this lens should be higher than 135 mm. I will measure that and update this review later on. Sharpness This is probably the sharpest lens I've ever used (think that, I'm a YouTuber and I tested a tone of lenses). Even at f/1.8 the lens is excellently sharp in the middle and the corners. The sharpness is excellent all through the frame and different focus distances, meaning that it is super sharp in the closest focus distance of 69 cm (by the way the previous manual focus version was focusing around 85 cm) to infinity. There is a very very tiny bit of axial/longitudinal chromatic aberration, very hard to see, no lateral aberration at all, no purple fringing that a can see and for astrophotography I didn't see any coma aberration (stars become cat eye shaped) so this is an excellent lens for relatively wide field astro photography. Bokeh Excellent, this is the reason I love this lens. The bokey is smooth (depending on the scene of course, you can still get harsh or disturbing background). In my research I saw that this lens cuts less of the bokeh balls around the corner compared to the Sony version. Ghosting Didn't try putting the lens in a condition that I get ghosting. But, I expect there will be some, above normal as the lens has a huge aperture opening. Usage with Samyang Lens Dock (WARNING!!!!) I bought the Samyang Lens Dock specifically for updating the firmware of this lens and setting button functions etc. During the firmware update, around 400th step of the 631 step progress, the connection between the lens dock and the computer has been lost. I see this is a very common problem with Samyang lenses. When the connection lost, you will definitely feel like you bricked your lens, because both the computer and the camera will not recognise the lens anymore and the lens will not function (aperture blades will be locked, no autofocus etc. the lens is practically dead). Don't panic, put the lens on to the dock again, select the correct com port (it was COM3 in my case) and without clicking to the connect button (which will complain no lens found), go directly to flashing firmware section, and select the file and apply the firmware. Hopefully in the second time the firmware will be applied properly and the lens will start working again as expected. Be warned about that but stay calm. Other than that with the lens dock you can change the functionalities assigned to the button on the lens, do focus fine tuning etc. Other than the firmware update problem there were no problem with the dock and I highly suggest getting one.
