Ikelite W-20 Wide-Angle 46mm Lens

*Note: The W-20 lens was made for cameras with a lens up to 35mm wide. Most modern cameras have lenses as wide as 24mm or 25mm. The W-20 will not work with these wider angle lens cameras because the W-20 will vignette.

Shoot larger

A wide angle lens is absolutely essential for shooting the big stuff like wrecks and whale sharks. Fit more of your subject into the frame for a photo with the same impact as the real thing!

The two photos below were taken at exactly the same distance. The photo on the left was taken with the camera in its widest angle setting. The photo on the right was taken with wide angle lens attached. The difference is clear!

Shoot smaller

It seems counterintuitive, but a wide angle lens can really make your macro shots pop. In many situations, the addition of an external wide angle lens can both improve the sharpness of your macro photo and expand the backdrop for more dramatic composition.

All of the following images were taken using US$100-200 point-and-shoot camera in Ikelite housings with external wide angle lens installed.

Get closer

biggest obstacle to good underwater photography is, oddly, the water. Water absorbs light and steals the color and clarity from your photo. Use a wide angle lens to get closer to your subject and get some of that water out of your underwater photos.

The Ikelite W-20 is a completely waterproof unit and can be removed and replaced while underwater for maximum versatility. Available with either 46mm or 67mm threads for easy attachment to almost any digital still or video housing. To check compatibility with Ikelite housings, please refer to the housing instruction manual or webpage.

Update 18/12/2020: There are some production delays at present that may increase wait times on items like housings. We apologise for the inconvenience. If there are any delays with your order, we will communicate this immediately.

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 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!

We wish to assure you, that when we begin fulfilling orders on 28 April, we will be following the government health guidelines surrounding safe operating procedures.

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.

These Nauticam housings are non-returnable, non-refundable, non-cancellable, and may be subject to extended lead times as they are manufactured on demand. We always do our best to meet trip deadlines so please advise us if you have a trip coming up!
