FAQs

A: TK Lenses only offers full rehousing services. This means that all existing parts from the original housing are discarded. For cine lenses such as Lomo, Cooke, and Baltar that come as an optical block, we use only the optical block to build a new lens with all new parts. For still lenses such as Canon FD, Nikon AI, Leica R, and Contax Zeiss, we use only the optical parts and discard the rest, including the original iris module. We then replace the iris with a new one that has more blades (from 11 to 16 blades, depending on the aperture diameter) to provide a rounded bokeh.

A: Much like other rehousing services, we do not source or provide donor lenses for rehousing. We only rehouse existing lenses provided by our customers. In very rare cases, we may sell rehoused lenses. When this happens, we typically post about it on our social media platforms.

A: The lead time for lens rehousing varies depending on our workload. Please contact us for the most current lead time.

A: Yes, we offer a 1-year limited warranty for our rehoused lenses. Any issues arising from a design defect or assembly error will be corrected free of charge, with the exception of shipping costs.

A: Please visit our pricing page for more information.

A: It’s important to be transparent that our pricing is more affordable because our rehoused lenses may not be of the same caliber as those offered by established companies. There are many factors that contribute to creating a high-quality rehoused lens, such as using expensive components, having experienced lens engineers and designers, and access to advanced machining equipment. While we strive to provide the best service possible, we do not have the same resources and capabilities as established companies. However, we believe in providing an affordable option for individuals who wish to rehouse their vintage lenses.

A: We aim to offer an economical lens rehousing service, featuring a robust full-metal housing, a matte box-compatible static front, a PL mount, extensive focus throw, and where feasible, an iris enhancement. However, due to the limitations of our equipment’s precision, some parts of the rehoused lens may appear somewhat loose or exhibit noticeable gaps. Cosmetic irregularities, such as marks or other visual flaws on the lens body, might also be present. It’s crucial to understand that our rehousings are primarily intended for operation with a motorized follow-focus unit requiring a minimum torque of 1N·m. While manual focusing is achievable, it might not be as smooth as with photography lenses. Additionally, focus and/or iris scales may be slightly off and not repeatable due to backlash in the system. You might also experience noise during focusing and irregular movement in the focus and iris rings. Furthermore, there’s a possibility of finding some dust inside the lens after assembly.

These lenses are more suitable for solo operators rather than a rental house or a professional set where absolute accuracy is essential. The best option for vintage lens rehousing is undoubtedly a professional, high-end service. However, recognizing that such services can be prohibitively expensive, we offer an alternative. While there are trade-offs, including the issues mentioned, our service provides a more accessible solution for those who cannot afford the higher costs of premium rehousing services.

A: We do not aim to compete with other established rehousing companies and their pricing models. Incorporating expensive components, experienced professionals, and advanced machinery would greatly increase our prices, which is not our goal. However, we may consider offering premium versions with better quality and higher prices in the future.

A: At this time, we do not offer lens calibration prior to rehousing.

A: We typically do not pre-rehouse sets for sale, but if we do, we will post a listing on our Facebook and Instagram pages.

A: We clean any external surfaces of the lens prior to rehousing, however, we do not perform a full clean, lubricate, and adjust (CLA) service on the lens or optical block.

A: We understand your concern for the condition of your lenses. Rest assured that we will handle your lenses with the utmost care during the rehousing process. However, please be aware that the process of rehousing, which involves disassembling, measuring, and testing the lenses, may result in some cleaning marks and/or dust contamination. We will do our best to minimize any damage and return your lenses in the best possible condition. However, please note that we cannot guarantee that the lenses will be returned in the exact same condition as received.

A: The mount of your lens doesn’t matter to us. We’ll get rid of the original housing, including the mount, and only use the optical block for the rehousing process.

A: Unfortunately, no. We do not rehouse zoom lenses at this time.

A: While it is possible to request certain customizations, it may take additional time and result in a higher cost for the rehousing process. Please check this page for more info.

A: We offer the option for the lens to have a metric scale on both sides, an imperial scale on both sides, or a combination of metric and imperial scales on each side. Please indicate your preference in the notes when placing your order.

A: Unfortunately, we do not offer repolishing or recoating services for lenses prior to the rehousing process.

A: Yes, there is a risk. Many anamorphic projection lenses have the front and rear elements glued together. During the process of removing the elements for rehousing, there is a possibility that an element may become cracked or chipped. It is preferred that you send only the lens elements to us. We can also remove the lens elements for you at a cost, but please be aware that we do not assume any risk or provide compensation if any damage occurs to the lens during the rehousing process. This means that the owner of the lens must be aware and accept the possibility of a total loss of the lens.

A: To place an order, please contact us via Facebook, Instagram, or email at nin at tklenses.com with the details of your lenses and any specific requirements. We will then confirm the cost and lead time for the rehousing process and provide you with shipping instructions.

A: If the lead time for the rehousing process is 11 months, we recommend sending your lenses 3 months prior to your production schedule. This way, you can utilize your lenses in the meantime and not have to leave them with us for an extended period of time.

A: At this time, we only accept wire transfers for payment. This can be done via traditional bank transfer or through Wise.com

A: At this time, we do not have any discounts available. However, we will post any promotional offers or discounts on our social media channels for our customers to take advantage of.

A: In the event that you wish to cancel your order for any reason within 2 months of making a deposit, a 3% cancellation fee, as well as any transaction and exchange-related costs, will be applied. However, after 2 months from your deposit date, we will not be able to cancel your order.
