Product Information

The Ikelite 200FL Underwater TTL Housing for Canon EOS 70D DSLR Camera is a clear polycarbonate underwater housing built specifically for the Canon EOS 70D DSLR, rated to 200 ft (60 m), and uses Ikelite's legacy Four Lock (FL) interchangeable lens port system with proprietary TTL circuitry for use with compatible Ikelite DS-series strobes.

Who it is for

This housing is for Canon EOS 70D DSLR shooters who want TTL flash control underwater with Ikelite DS-series strobes rather than a slave or fiber-optic triggered strobe. Back-of-housing controls work as a remote for the strobe, giving access to plus/minus exposure compensation in TTL mode and manual power adjustments in half-stop increments without taking a hand off the housing.

Key details

The housing is built from clear polycarbonate so the main o-ring seal and the camera inside remain visible before and during a dive, and it weighs 5.5 lb (2.5 kg) with dimensions of 10 x 6.9 x 6.5 in (25.4 x 17.5 x 16.5 cm) and slightly negative buoyancy in fresh water. The Four Lock (FL) port system accepts zoom, macro, and wide angle lens ports, sold separately, and an oversized zoom knob engages Ikelite's universal zoom gears without modifying the lens. All important camera functions are accessible, though no controls are provided for the Dioptric Adjustment Knob, Flash button, Multi-Function Lock Switch, or Depth-of-Field Preview Button. Ikelite's current product lineup lists this housing as discontinued and replaced by the 200DL Underwater Housing, which uses the newer DL port system.

Compatibility and sizing

This housing fits the Canon EOS 70D DSLR camera and pairs with Ikelite DS-series strobes for TTL or manual exposure control. Two universal zoom gear sets are included, one for lenses up to 2.8 inches in diameter and a second for lenses from 2.8 to 3 inches in diameter, so no lens modification is required.

Frequently Asked Questions

How do I check an underwater housing's seal before a dive?

Before every dive, open the housing somewhere clean and dry, inspect and wipe the main o-ring and its groove, and close it with nothing trapped in the seal, because a single hair or grain of sand is enough to flood it. Confirm every latch is fully closed and that any vacuum or leak alarm reads correctly. Where you can, soak the sealed housing in a rinse tank or hang at the surface before descending, so a leak shows up before depth.

How do I care for housing o-rings?

Remove the main o-ring regularly with a plastic tool rather than anything metal, which can nick the groove, and clean both the o-ring and the groove with a lint-free cloth. Apply a thin film of the silicone grease the manufacturer specifies, since grease helps the o-ring seat and slide rather than sealing by itself, and a thick coat only collects grit. Replace o-rings on the schedule in the manual, or sooner if they look flattened, cut, or dry.

What do moisture alarms and desiccant packs do?

A moisture alarm is a sensor inside the housing that beeps or flashes when it detects water, giving you a chance to abort the dive before the camera is ruined. Desiccant packs absorb humidity in the air sealed inside the housing, which prevents the port fogging as you descend into cooler water. Neither replaces a proper seal check, since they provide early warning and fog control rather than leak prevention.

How deep can I take an underwater camera housing?

Only as deep as its rated depth, which the manufacturer sets and publishes in the specifications, and it should never be exceeded even briefly. Depth ratings assume a housing in good condition with intact seals, so worn o-rings or a damaged port reduce the real margin. If your diving might take you deeper, choose a housing rated comfortably beyond your planned maximum depth.

Can I use a phone housing for scuba diving?

Only if the housing is specifically rated for the depth you plan to dive, because many phone cases are splash- or snorkel-rated rather than scuba-rated. Touchscreens generally do not respond underwater, so a diving phone housing needs mechanical buttons or another control method. A phone's own water-resistance rating is not a substitute for a housing, and any housing still needs seal checks and o-ring care.

How do I rinse a camera housing after diving?

Soak the closed, sealed housing in fresh water and work every button and dial while it is submerged so salt does not dry inside the control shafts. Let it dry completely, especially around latches and seams, before you open it, since opening a wet housing drips water straight onto the camera. Avoid opening a housing on a wet, moving boat deck whenever you have the option to wait.

What should I do if my housing floods?

Get the housing out of the water and open it somewhere dry, then immediately remove the camera's battery and memory card, because leaving a battery in a wet camera does more damage than the water itself. Do not power the camera on to check whether it still works. Dry everything gently away from direct heat, get salt-water-exposed equipment to a repair technician promptly, and inspect the housing to find which seal failed before you dive it again.

Is the Ikelite 200FL housing for the Canon 70D still in production?

No. Ikelite's current product lineup lists the 200FL housing for the Canon EOS 70D as discontinued and replaced by the 200DL Underwater Housing, which uses the newer DL port system instead of the legacy Four Lock (FL) ports used on the 200FL.

Does the Ikelite 200FL housing include a lens port?

No. Lens ports are sold separately. The 200FL uses Ikelite's legacy Four Lock (FL) port system, which accepts a variety of zoom, macro, and wide angle ports that lock and release with four latches.

What strobes work with the Ikelite 200FL housing?

The 200FL is designed to work with compatible Ikelite DS-series strobes in either TTL or manual mode. Back-of-housing controls act as a remote for the strobe, giving plus/minus TTL exposure compensation and manual power adjustments in half-stop increments.

What zoom lens sizes fit the Ikelite 200FL's zoom gears?

The housing ships with two universal zoom gear sets: one for lenses up to 2.8 inches in diameter and a second for lenses from 2.8 to 3 inches in diameter. Both install without any modification to the lens.
