Samyang lens repair
High-precision laboratory specializing in the Repair, calibration and reprogramming of Samyang lenses. We have access to factory software settings, resolve diaphragm locks, calibrate AF motors, and guarantee perfect centering with our high-resolution projector and collimator.
Complete solutions for Samyang optics malfunctions
As an Official Technical Service, we don't just handle mechanical failures. We combine software diagnostics (vital in the new AF lines) with the millimeter-precise adjustment of glassware in our optical laboratory.
Software Reprogramming
Direct connection to official systems to update firmware, resolve camera recognition failures, and apply micro-adjustments of focus (back/front focus) that restore accuracy to the AF system.
Correction of Offsets
A soft lens at one end is a common problem after an impact or wear. We are one of the very few workshops with collimator and resolution projector to geometrically align the optical groups and restore extreme sharpness.
AF Engine Repair
Diagnosis and replacement of worn-out Linear STM motors and autofocus assemblies. We fix lenses that hesitate when focusing, make squeaking noises, or have stopped responding to camera commands.
XEEN Film Series Maintenance
We service cinema lenses and the Cine DS family. We eliminate play in the follow focus gear rings, re-grease the helical gears for smooth operation, and calibrate light transmission and focal throw.
Diaphragms and Base Plates
We replace severed flex cables and repair stuck diaphragm blocks. We also resolve motherboard (PCB) problems and damaged electronic contacts that prevent the f-number from being read.
Internal Chemical Cleaning
Safe disassembly of sealed lenses to eradicate fungal growth through specialized chemical cleaning. We remove internal condensation, oil mist, and dust accumulated in deep clusters.
Has your Samyang camera lost sharpness, is the ring skipping, or is the camera not recognizing it correctly? As an authorized service center, we'll thoroughly evaluate it and provide you with a... Free, no-obligation quote.
Your Samyang lens, in the hands of the authorized laboratory
The workflow at DST integrates mechanical checks and software audits. Whether you send us your optics from the other side of the peninsula or bring them in person, they will receive the technical service required by the manufacturer.
Reception and Inspection
We catalog the lens, evaluate possible aesthetic damage, tolerances in the mount and the smoothness of the focus rings or manual diaphragm.
Dual Diagnosis
We connected the lens to our software diagnostic terminals to read errors, and mounted it on test benches to evaluate the engine's mechanical response.
Free Estimate
You'll receive a precise, no-obligation assessment. We'll let you know if it requires electronic replacement, mechanical work, or calibration.
Collimator Adjustment
After repairing it with official replacement parts, we project the resolution of the crystals on our collimator to ensure that the focal flatness is perfect before shipping.
Samyang lens park that we repaired in the workshop
The Samyang/Rokinon ecosystem is known for its immense variety of mounts. We offer repair and adjustment for their native lines designed for the leading brands of mirrorless and SLR cameras on the market.
A multidisciplinary optical universe
The new generation Samyang AF models incorporate complex electronics and stepper motors (STM). We address mechanical and motherboard failures while adhering to the manufacturer's strict protocols.
Our exclusive technology: Many workshops refuse to adjust third-party lenses due to a lack of tools. We have the official software and a collimator and resolution projector. This is vital at Samyang: it ensures we correct any factory or usage-related misalignment, restoring optical performance without strange vignetting.
We exclusively use replacement parts supplied by the brand, from helical gears to diaphragm units and sealed bayonets.
Most requested interventions
We resolve the most common mechanical, electronic, and software issues:
- Firmware update and AF adjustment via software (Lens Station).
- Millimeter calibration of decentered lenses in projector.
- Replacement or repair of Auto Focus (Linear STM) engines.
- Unlocking and replacing diaphragm assemblies.
- Reconstruction of electronic contacts (camera reading errors).
- Maintenance of manual optics (lubrication, ring adjustment).
- Replacement of scratched front lens or deformed bayonet.
- Deep cleaning of fungal spores and internal dust.
Why choose us for your Samyang optics repair?
Samyang trusts us as their Official Technical Service. This means that our intervention meets the highest standards of the brand, integrating direct access to technical information and proprietary software.
Unique Equipment in Spain
Modern optics require much more than simply replacing a part. Many focusing problems in the AF series are resolved by deep software reprogramming and adjustments to which we only have access as Official SAT.
Furthermore, at the hardware level, the calibration of the glass in our collimator certifies that the resolution and sharpness of your Samyang is correct, solving the classic problem of decentered lenses at its root.

Is your Samyang camera malfunctioning or having an inaccurate focus?
At the Official DST Service Center, we analyze the electronics and mechanics of your lens to offer you a Free, no-obligation quote.
We updated the firmware, calibrated the AF, and centered the lenses with a collimator, offering official 6-month warranty and collection throughout the peninsula.
Common questions about Samyang optic repair
We answer the most frequently asked questions about our Official Technical Assistance Service, software calibrations, and the process of Repair of Samyang and Rokinon lenses.
Is there a cost for the estimate to repair my Samyang lens?
Absolutely not. As an Official Technical Service, we offer a diagnosis and preliminary estimate completely free. We evaluate electronic communication, motors and optical groups, informing you of the feasibility and cost without obligation on your part.
Do official repairs come with a warranty?
Yes. All our services, whether deep firmware updates, STM motor replacements, or collimator alignments, include 6 months certified technical warranty and official spare parts.
Do you solve focus problems (front/back focus) or camera errors?
Yes, electronic communication failures or autofocus inaccuracies are very common. As the official service center, we have access to exclusive software tools (Lens Station and our own terminals) to update circuit boards, reprogram lens recognition on your Sony/Canon/Nikon, and apply focus micro-adjustments.
What is the collimator used for and why is it key in third-party objectives?
The collimator and resolution projector are highly specialized and rare pieces of equipment in Spain. They allow for the geometric alignment of internal lenses. Samyang lenses are fantastic, but they sometimes suffer from misalignment (part of the image appears blurry). With the collimator, we recover perfect sharpness from corner to corner, guaranteeing mathematical infinity focus.
Do you also repair the XEEN Cinema series or manual lenses?
Yes, we repair the entire Samyang catalog. From their acclaimed AF series for photography, to the robust V-DSLR cinema lenses and the premium XEEN line, where we resolve play in focus rings, re-grease systems, and remove dust.
Can I ship my Samyang lens from anywhere in Spain?
Yes. We work with secure transport agencies to collect your lens (E-mount, RF, X, L-mount, etc.) anywhere on the peninsula, ensuring that the equipment travels fully protected to our workshop.
