The UCL-67 M67 / LD underwater close-up lens is designed to deliver high magnification yet superior image quality best suited to full frame SLR macro lenses of focal length 60mm - 100mm with comfortable long working distance enabling easy lighting. The lens also supports mirrorless as well as compact system.

(*1) This lens is designed solely for underwater use and using on land will not magnify a subject and will have distortion on image edge or or vignetting etc.

High Power +11 Close-up Lens

The maximum magnification when using this lens with 100mm range macro lens for a full frame SLR system is x2.23 (area ratio x4.98) (*2) which delivers middle power in between『UCL-67 M67/UCL-67 LD』(+15 diopter) and『UCL-165M67/UCL-165 LD』(+6 diopter). High power close-up lens with underwater focal length of 90mm which is equivalent to +11 diopter.

Long Working Distance for Comfortability

While the UCL-90 delivers high magnification, it still offers long working distance.  When using with 100mm range macro lens for a SLR system, working distance (from front edge of the lens surface) is 69mm (*2) at minimum focusing distance.

(*2) Usable zoom range is between 60mm and 100mm (35mm film equivalent). Beyond this range, there will be vignetting at wider side and deteriorated image quality at telephoto side.

High Quality All Focus Range

Optically designed sole use underwater(*1) to effectively suppress aberrations in all focus range to deliver high contrast and sharp images despite of shooting distance.

    April/May 2022 Delays:

    Due to further Omicron outbreaks in China, some products may be delayed. Not all brands or products will be affected by this. As some products are kept in stock as a matter of course, these should not be affected.

    If you need things urgently please contact us and check ETA on the items you require.

    International Shipping

    At the moment, our website is only set up to ship within New Zealand. If you live outside New Zealand, please contact us and tell us your full shipping address and what you want to purchase. Please note that our free shipping offer applies to NZ shipping only. Our preferred method of shipping internationally is DHL.

    How long will it take for my order to arrive after I make payment?

    That depends on where you live and whether we have an item in stock or not. While we do have many items in stock, we don't carry everything. If you need an item in a hurry, it's a good idea to contact us and find out if your item is in stock.

    If we have it in stock, we can usually send it out as soon as we receive payment, or you can pick it up. If an item is not in stock, we'll need to order it from our suppliers, which means it can take 1-2 weeks to arrive at your door (usually closer to a week).

    Sometimes delivery can take longer, if our manufacturers are out of stock, for example, but this is unusual - we let customers know as soon as possible if something like this happens.

    How do you ship my NZ orders?

    We use New Zealand Post and CourierPost to ship orders. Our default is courier, though you may organise an alternative with us by contacting us directly. CourierPost aims for next day delivery nationwide between major towns and cities in the North Island. South Island delivery can take two days. If you require next-day delivery in South Island, choose the express shipping option for the South Island. If you spend over $250 get your shipping for free!

    When you buy something from us, the price is literally exactly what it says on the tin.

    If you buy something from an overseas supplier, that is most definitely not the case. While the product might seem like a great deal on screen, it's important to understand customs and import costs.

    In addition to the ticket price on an overseas purchase, whatever the exchange rate is on the day (this can fluctuate wildly - trust us, we know), there are also tariffs, GST and border processing fees. This can easily add upwards of 25% to the ticket price. Items costing over NZ$1000 also incur import entry transaction fees.

    In addition to these extra costs, Customs clearance can also cause delays. Sea Tech has been importing for years - we've got this down to a fine art, and we've built relationships with customs that help our items clear quickly.

    By buying from Sea Tech, you avoid all the headaches, delays and extra costs. We handle all this stuff for you, so you don't even have to think about it.
