2、 SpecificsThe Olympus OM-D line are by far the most popular mirrorless camera used in underwater photography. The newest version, the OM-D E-M5 offers nice improvements from the original E-M5, while continuing with the quality and excellence that one expects in an Olympus mirrorless camera.In this a

15、e best underwater shooting experience.Most Important Settings for Underwater Use:1) Custom Menu Options - The Custom menu should be turned on by default on the E-M5, if not, follow these instructions to activate it.Menu -> Set Up Menu (Wrench icon) -> Menu Display and click OK.

16、The Custom Menu is the small cogs icon, hit the right button, and then the down button followed by ok to activate this menu.2) Live View Boost - this is very important so that you can see your LCD underwater. This mode disables the live view of exposure settings, since underwater shoo

17、ting with a strobe, usually results in dark settings in the camera. This function will brighten your LCD so it is always at a good viewing brightness. Note: the LCD does not accurately reflect the exposure settings for the camera.Custom Menu -> D: Disp/PC -> Live View Boost -> Manual Shooti

18、ng -> On1(note On1 is the standard view, On2 offers a slow frame rate option that will improve total visibility when shooting in very dark conditions)3) EVF Auto Switch -  The E-M5 has an electronic viewfinder. In order to use the LCD screen underwater you need to turn off the

19、 Auto Switch. This prevents it from automatically switching to the EVF when the sensor is blocked, since the back of the housing blocks that sensor.Custom Menu -> J: Built-In EVF -> EVF Auto Switch -> OFF. (NOTE: You can also access this menu item by simply pressing the |O| (EVF) Button on

20、the camera and holding for about 3 seconds)Note: You lose the ability to display the Super Control Panel in the LCD when using the viewfinder when the "Auto Switch" is turned off. The default is Live Control, which is the same quick menu as previous PEN models. If you prefer the look of th

21、e Super Control Panel you can gain access to it by turning off the Live Control and turning on the SCP through the Custom Menu.Custom Menu -> D: Disp/PC -> Control Settings -> P/A/S/M -> Live Control OFF -> Live SCP ON                  

22、0;      The Super Control Panel on the left, and the Live Control View on the right.4) Flash modes - if you are using a strobe with TTL you will use the single lightning bolt "Fill in Flash" mode on the camera. However, if you are planning to use the stro

23、be in manual mode you can save battery life by changing the flash mode to "Manual Value" through the quick menu. This is also beneficial because using the internal camera flash at a lower power means less recycle time and helps eliminate any delay on being able to take a picture.OK -> s

24、croll to flash icon -> scroll over to select "Manual Value Flash" -> Press INFO to change flash power -> scroll to 1/64th power -> OK to confirm*Important Note: Remember that the new style of flash on the E-M5 Mark II requires it to be turned on before it will work. Make sure y

25、ou switch it on and test that it is firing properly before closing your housing.*5) Rear Control Buttons - the default setting on the EM-5 four arrow key rear buttons controls only the focus point, which basically means you are not taking advantage of 3 out of 4 buttons! You can custo

26、mize 2 of the buttons instead to gain quick, one-touch access to important features.Custom Menu -> B: Button/ Dial -> Button Function -> Key Function (option with the four arrow key icon) -> Direct Function -> OKNow you have access to change the right and down arrow key controls on th

27、e back of the camera. (Up gives control of Aperture / Shutter Speed without the dials and Left gives control over the focus point, these are NOT customizable). You have the same options for both customizable buttons, I suggest reviewing each and picking the ones that best suit your needs. For exampl

28、e, I set my camera to have direct access to the flash mode via the right arrow key and direct access to the sequential shot/ timer mode for the down key. (The sequential shot is not something used much underwater but I find I use it alot topside, so it was important to have direct access for me.)6)&

29、#160;Rec View - this sets the length of time an image review is displayed after taking the picture. Default is 0.5 seconds. For underwater use, 2 seconds is usually recommended so you have a chance to quickly gauge that exposure and focus look good before taking another picture. If 2 secon

30、ds is too long, set it to what you desire, or simply press the shutter halfway down to cancel the review.Set Up Menu -> Rec View7) Picture Mode - the default is natural, but jpeg shooters may prefer VividNOTE: this does not affect RAW filesAccessible through the SCP / Quick Menu or

31、 Shooting Menu 1A Note About Handling the E-M5 Mark IINever, never hold or carry your E-M5 Mark II camera by the flash. I have found that the connection with this new style flash is finicky, and it must be fully installed to send the correct signal to the camera and allow the flash to fire. There we

32、re several dives when I was testing this camera where the flash was greyed out because the camera could not send the signal to the flash. If you lift up, or pull out the camera by the flash you will weaken the connection point between the camera and flash and it may result in your flash not function

33、ing. Always grasp the camera by the body only. If you do install the flash on the camera, switch on and the flash icon on the screen is still greyed out, please simply press gently on the flash like you are trying to push it further into its slot. This worked for me to get the flash to activate

34、 when this would occur. Once in the camera and on, be careful not to jostle the camera / housing too much to prevent the flash from disengaging.OM-D E-M5 Mark II Set Up For an Olympus Housing:The Olympus housing is a great option if you are on a budget and don't want to spend the money on one of

35、 the more expensive aluminum housings. There are a few limitations, but for the most part set up is the same as other housings.  Important Olympus Housing Information:Before taking your rig underwater these things MUST be completed to ensure proper functionality and minimize the risk of a

36、housing flood.1) Remove the rubber grommet from around the Electronic Viewfinder, also called the “Eyecup”. To do this make sure the accessory flash is off the camera, and then simply slide the piece up and off the camera. Remember to replace the flash before putting the camera in the housing.2

37、) Remove any straps, filters or lens caps.To insert the E-M5 Mark II into the Olympus housing you should follow these steps:1) Turn camera OFF2) Keep LCD closed (not pulled open on its hinge)3) Check that the ON/OFF lever on the housing is raised up and in the OFF position, if not, gently push up on

38、 the lever.4) Set the 1:2 Switch lever to 1 on the housing (make sure its also set to 1 on the camera)5) Gently slide the camera into the housingOnce the camera is in place you can close the housing and the 1:2 Switch will connect correctly. Then press down on the ON/OFF switch so that it lines up c

39、orrectly (you can do this before closing the housing to confirm correct placement).Always test your housing underwater without the camera installed for the first dive. This will ensure there are no manufacturing defects.Olympus Housing Menu & Button Configuration:Like all cameras, the OM-D E-M5

40、Mark II focus set up comes default with auto focus occurring after a half press of the shutter button. This works fine in most situations, so if you are happy with the half press focus, then nothing needs to be changed.With the PT-EP13 housing there is not an ideal button configuration to use the mo

41、re advanced option of splitting out the focus. Typically you want a button that would be activated by your thumb, so if needed you can quickly focus (with thumb) then take the photo (with your pointer finger).If you would like to have the ability to split out the focus, it can be done, just keep in

42、mind that you will be focusing and taking the photo with your pointer finger, so it may be a little slower.Please remember this set up is an advanced option and is not required to use the camera underwater. Please only change out your focus set up if you understand the steps. Otherwise leave at defa

43、ult, and use a half shutter press to focus with a full shutter press to capture the image.Button Configuration for Split out FocusButton Functions ( Custom Menu -> B: Button/Dial -> Button Function)Fn1 - MF - this will allow you to switch between the Manual Focus and S-AF focus

44、on the camera with one press.Fn2 - AEL/AFL, this will become the button you press to focus the camera.Rec - Leave as Record for Movies.Set Up When Using AFL Focus with Fn1 & Fn2 Buttons:AEL/AFL Settings (Custom Menu -> A: AF/MF -> AEL/AFL)Use these settings if you've ass

45、igned MF to the Fn1 button.S-AF - Mode 1 - this will basically keep the camera as default, where a half shutter press focuses, and a full shutter press takes the picture, which is how most folks shoot topside, for wide angle underwater where focusing is not a touchy as macro and for subjec

46、ts underwater where you want to re-focus each shot.C-AF - leave at Mode 1 - i try not to use C-AF on the E-M5 as it can be slow, and will refocus your image automatically. Often it focuses different then where you want.MF - Mode 3 - this separates the shutter release from the auto focus, s

47、o you can lock focus and then take as many images as you like without affecting your focus. In addition to this, Manual Focus is active so if you have a focus gear on the lens you can use both MF and AF quickly and easily without changing any modes.Shutter Release (Custom Menu -> C: Release

48、-> Rls Priority S)Rls Priority S - OFF - this prevents the camera from taking a photo unless it is in focus in S-AF mode. If you want to be able to take a photo even if the camera has not locked focus then turn this function ON. (Release Priority C is the same only for the C-AF Mode).Now onc

49、e you have set all of these, you can shoot a picture as standard (half shutter to focus) when in S-AF mode. Simply press the Fn1 button to switch to Manual Mode and now the Fn2 button controls auto focus and the shutter release only takes the picture. This makes it very easy to have both topside set

50、tings and underwater settings created without having to change things in the menus every time you use the camera, so you do not forget to reset anything for the next trip.NOTE: I use all of these settings with the camera in Manual Mode, so I have full control over my exposure settings. OM-D E-M

51、5 Mark II Set Up For a Nauticam Housing:The E-M5 Mark II camera and Nauticam housing require no changes to the camera, you can leave the Eyecup in place and there is plenty of space for the little triangular strap attachment pieces. It is important to note that any camera strap, lens cap and lens fi

52、lters need to be removed before you install the camera into the housing.The OM-D E-M5 Mark II comes set up with defaults that work well on land, but might not give you the best possible results underwater. If you have set the primary settings as outlined in the beginning, this section will help you

53、streamline the camera for quick and accurate auto focus underwater when using a Nauticam Housing.The Nauticam Housing does not include any tray or handles, though it does come with the silver brackets that add support when using the Nauticam Flexitray system. I highly recommend this tray as it is ve

54、ry adjustable, allows the housing to stand flat on a table and is very secure. One downside is that if you do need to adjust something, there are at least four, sometimes more, screws that have to be loosened, then retightened so it can be a pain.I prefer to move the tray (any tray) further to the r

55、ight, to allow a space large enough for my hand to fit between the housing and the handle. This way I am gripping the housing directly. I find it positions my fingers much better for accessing all the controls and buttons.Advanced Focus Set Up in the Nauticam Housing:One of the biggest benefits to t

56、he Nauticam housing over the Olympus is that they set the rear of the housing up differently than the camera. The record button on the camera is actually a small lever on the housing, set right by your thumb. With the advance customization available on the E-M5 Mark II you can easily reassign the Re

57、cord Button to be something different. I prefer to set it as the AEL/AFL setting.AEL/AFL -  You can assign this option to one of the Fn buttons or even the record button. This can be helpful to separate the focus lock from the Shutter Release. Often underwater it is hard to focus exac

58、tly where you want with the camera re-focusing every time you press the shutter half way it down, especially when shooting macro. Separating these allows you to focus the camera, then take the picture and take multiple pictures without the camera refocusing. This is very helpful for lenses like the

59、60mm and 45mm Macro that tend to focus hunt often.Please remember this set up is an advanced option and is not required to use the camera underwater. Please only change out your focus set up if you understand the steps. Otherwise leave at default, and use a half shutter press to focus with a full sh

60、utter press to capture the image.Here is how I have my OM-D E-M5 Mark II buttons assigned when shooting in the Nauticam housing, I find this the best set up for quick changes to focus mode, so that focus can be achieved quickly, easily and accurately.Button Functions ( Custom Menu -> B:

61、 Button/Dial -> Button Function)Fn1 - One Touch White BalanceAlternately - if you want to be able to record video at the touch of a button (vs changing the actual mode) you can assign the video record to the Fn1 button.Fn2 - MF - this allows you to switch quickly between MF and your default focus mode (S-AF is recommended). This is great for using the AEL/AFL feature. (Note: this comes into pl
