lanwu:
Can anyone verify if these work together??
For sure, the Tetra/L&M sell their own wide & macro lenses for the Tetra housing, but can we use the INON Wide & Macro lenses instead??
Would esp. love to hear from users with this equipement....Tahnks....
The tetra does NOT come with a threaded port, it is available as an option. Or can sometime be found used for around $200-250, which is the cheapest way to go. Then buy Inon lenses. Ryan at Reef Photo & Video has one used, in stock as of a day or two ago.
With the Tetra housing, you will need a TYPE 1 lens, not a type 2 like the Oly PT-15 uses. The ring on Inon lenses are changeable to make them type 1 to type 2 or vise-versa. Type 1 and type2 are the same lens except for the ring which is added to the lens to screw onto 67mm. On one the lens sticks out past the threads (Type 1), to other (type 2) the threads are flush with the back of the lens. On the tetra, Type 2 lens will screw onto the housing, but it will give you some problems. A type 1 lens will NOT screw onto the PT-15 housing.
Your Inon macro lenses are not a problem, they will screw right on for use with the tetra, if you have the optional port with threads.
The tetra does not have the feature Ike has concerning holding down the buttons. You can however use your thumb to turn the rear dial on the camera. In-fact, one full pull with the thumb only changes one step at a time, so you can change shutter speed, or F stops with out looking to see where you are. I love the way they geared in that aspect.
The tetra 5050 does not have a on\off switch. The camera goes to sleep with no problems, and saves the power of the batteries. However, if you let it sleep for more than 4 hours, the camera does turn itself off, which does require you to open the housing, and turn the camera off.....then back on. I've never had the happen, as I put everything together the night before, and seal it just before I leave my A\C room, on the way to the dive boat.
Hope this helps some.
