Sea & Sea MDX Underwater Housing for SONY A73 or A7R3 Reduced to $1900

includes the installed Sea & Sea Optical YS TTL Converter (Internal)

Retail price: $4,025.90



Sale includes Housing with left and right arms, ttl converter and body cap, only.

(Note that you will need to buy a port appropriate to your lens.)

The housing is well maintained, never flooded, dropped or otherwise abused (although it is so solidly constructed it could probably be used to drive nails, or as a jack stand for a full sized sedan or mid-sized SUV!)

The only real signs of wear are brassing (black finish worn thin) on bottom plate and corners due to rubbing in Pelican case, boat decks etc.

The installed optical converter allows for ttl (through the lens) exposure metering to communicate with your strobes.

Included in the sale is the SONY Hot Shoe Adapter Adp-maa. This is required to connect the Sea & Sea Optical Ys TTL Converter to the A7RIII hot shoe.

The controls on this housing synch up with those of the SONY A7III and A7RIII, only. The A7III and A7RIII were the first to use the extended life Z battery, which is still used in the latest model A1ii. This battery is a breakthrough in improving mirrorless camera battery life to get closer to that of DSLRs. The implication is that you do not have to open the housing to replace the battery after each dive. The SONY model A7RIII’s high resolution sensor and processor still compare favorably with later models.

Reduced to $1900.

Insert description of model.

I would be interested. Which dome port would you recommend for the housing?

Housing is still available. I shoot with the NX Compact Dome Port. I have sent a longer reply to you via direct message.

Best,

John
