Hi all,
I just bought the Canon 5D Mark II. While I'm waiting the UW casing, can any one recommend the right len for both marco and wide angle.
Would the len of 17 to 40mm do the job?
Thanks a lot.

Carl
 
welcome aboard
 
Welcome to the board Carllam. . .For a quick answer, the two types of underwater photography are competing interests. Wide angle photograpy really needs a "dome" port, and Macro needs a flat port for best results. Now to change what I have just said. . . Many photographers will use the lens you mention, with a flat port and just shoot what is available. It's not the best choice, but it is a good choice for the beginner.

There are many surprising changes in underwater photography over shooting on the surface. Learn from the experience of lots of divers that have gone before you. Click on the "Forums" button at the top of any page, and watch the long list of topics open up for you. Scan down that list of "interests" to "Underwater Photography". Within that topic are sub-catagory for Canon, Nikon, Olympus as well as general comments about photography. Read of the experience of each of the camera topics. You'll find "Cannon Heads" and "Nikon Heads" what the camera says on the front has less to do with good pictures, than the techniques you can learn from either group of photographers.

Did you know that underwater cameras flood? Do you know how to reduce but not eliminate flooding? Do you know where to insure your camera agaist loss from a flood?

And before I scare you off. . . Go to the top of each page and click on "Photo Gallery" there are thousands of pictures of underwater activities, and many of them discuss what photo equipment they used. Many of these are cheaper point and shoot cameras, but in the right hands are very capable of great pictures, Many are pictures by Cannon or Nikon DSLR's with wide angle or macro lenses, have a look at their results, then search for answers on the Photo board. Good luck. . . don't get discouraged, It is a steep learning curve to shoot underwater, and you'll read that all the automatic stuff on the camera, won't work the same underwater, as it will above water.
 
Holy crap, talk about a do this and you will die, but don't worry post, geez :shakehead:

To answer your question, you need a wide angle lens to shoot wide angle, macro to shoot macro. There is no good universal lens to shoot everything. A 17-40 would not be a bad lens to start with for wide angle. You will need to buy different ports for the different lens. For underwater wide angle you want to use a really wide angle lens, many people like something in the 12mm range.

You can shoot underwater without flooding a housing, it can be done. I have 2 camera's I use all the time and never flooded once. Almost all floods are caused by operator error. Orings almost never fail suddenly. So as long as you pay attention and do preventive service, you should never flood. That said, equipment insurance is always a good idea. You never know when someone will walk off with something or the airline flight attendant will jam another bag into that already full overhead.

There are a lot of good threads on photography here, there are also a lot of good web sites, google is your friend. Read the housing mfgr's instructions very carefully on how to care, assemble, and use your housing.

Don't expect great pictures right away, it will take some time. Have you ordered a strobe yet?

Hi guys,
Thanks a lot for your prompt and informative reply.
I'll definitely spend some times to go through the forum.
In fact I just learnt diving last March. I know I shouldn't have jumped to UW photo-taking so soon... but just too addicted to both diving and photo-taking. So I made effort to practise controlling my buoyancy. In my last trip, I managed to take most of the photos without touching coral or sand bed.
Now I have about 50 dives and luckily I had the opportunity to film thousands of barracuda and even whale sharks last month.
Here are some of my photos:
(I'm only allowed to post the link later-after 5 posts)
I know I need to switch to DSLR to improve my photo quality.
Sometimes I also wonder how people could get so close to the fishes when taking macro. I may need to be patient but if I wait too long for the fishes, all my buddies have gone.
Thanks again and very glad to talk to you.
Carl

Something I said scared fppf. . . "do this and you'll die". Many of the diving deaths I've known about are directly connected to a photographer, not paying attention to the dive, or partner. . . but only trying to get that great picture. Two divers drowned when one entered a cave to take a picture of his partner (Skin Diver Magazine had that as a cover picture a month before) both divers entered the cave and ran out of air. On an easy dive in Bonaire, an inexperienced diver, pro photographer ignored his partner that had passed out an was laying on the reef when a friend found him and brought him up. On a trip to the coral sea, a macro photographer ignored his partner and fell way behind the boat and all the rest of the divers. . . his little black dot of his head was hard to see, but the divers stayed and searched until they found him. . . There is a common thread for unsafe diving practices, when something is more important that safety.

To get close to fish, you must learn why they fear some things and not others. Any underwater movie will show sharks swimming in the middle of smaller fish. Why, because they are always around, and the fish not directly in front of the shark don't feel threatened. All fish fear something bigger than they, from the time they hatch. Any predator on the reef must swim straight at the prey, and the prey can see this. If the predator is just cruising the reef, and is not "head on" the other fish will watch it closely but not panic.

As an underwater photographer. . . avoid looking straight at the fish you want to shoot. From a distance the fish doesn't react to, angle your approach to get closer, then shoot to your side. . . If in scanning the reef for photos, swim smoothly without using your hands, and angle slightly deeper than the fish you want a picture of.

Try to capture the picture like a news photographer. . . what's in front of you, while you watch all around you for something better, and you will be still aware of your buddies. Your buddies will stay closer to you if you will shoot their picture. Find a pretty sponge, or coral head. . . have your buddy approach you, as you use hand signals to position him behind the coral. Then watch and snap your picture as he is releasing a string of bubbles.

Your safety and your buddies safety is all about putting safety ahead of a "great" picture. Your dive buddies will stay close if you take their picture once or twice a dive.
 
Hi mudhole,
Thanks so much for your advice. I promise my wife I won't risk my life for photos and I'll try to keep my promise.
It's intersting topic to peep on the fishes. It may take some times to practise how to pretend causally swim pass the fishes. Sometimes I also wonder why UW photograhpers do not tie sea weed on their gear to have better camouflage. Silly question, isn't it?
 
Hello Carl,

Welcome on board!
There is a great versatile lens, which can be used in wide and macro as well.
The Tamron 17-70 becomes very popular, you should check it out.

All the best,

Michel
