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.

Official Methodology

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.

1

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.

2

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.

3

Free Estimate

You'll receive a precise, no-obligation assessment. We'll let you know if it requires electronic replacement, mechanical work, or calibration.

4

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.

Free quote Technical analysis and initial laboratory data reading are completely free.
Official Certification Service backed by the brand, ensuring genuine spare parts and a 6-month warranty.
National Logistics Delicate glassware collection and delivery service, insured throughout Spain.
We service the entire Samyang portfolio: from their classic ultra-bright manual lenses, their modern and fast Auto Focus (AF) line for mirrorless cameras, to the cinematic XEEN and V-DSLR series.
Compatibility and Mounts

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.

Frequently asked questions

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.

If you have any other technical questions about your Samyang optics, you can contact us and our specialists will advise you.
