Even so, the modern mirrorless systems nowadays have a decent battery lifetime, that gets you through the day, it can be yours that you get into situations where you must be economical with the remaining energy. I would like to give you a few tips and hand that will enable you to continue working as long as possible.
Tip 1 Use the display not the viewfinder!
Even though the back display of your camera is much bigger than the display in your electronic viewfinder, it needs much less energy. This sounds weird but is logical. The viewfinder has much more pixel and as switching pixels needs energy the viewfinder needs more energy. Besides, the refresh rate of the viewfinder is much higher than the one at the back display. This needs also more energy.
Tip 2 Reduce display brightness!
Once you are using the back display you could optimise the setting. By reducing the brightness of the display you can save additional energy and extend battery life.
Tip 3 Switch of image stabilisation!
Olympus OM-D camera does have fantastic image stabilisation, but to be able to correct movements it needs energy. In case your battery life is at the end you have to decide whether you would still use the image stabilisation or not, but you can shoot some more images.
Tip 4 Switch off Autofocus!
Even though that manual focus in a modern camera is realised by electro motors, you are able to save energy in case you switch off the autofocus. Especially when you are shooting slow-moving object as you just have to set the focus once. The autofocus on the other side is moving the motor every time you half-press the release button. Alternatively, you could use the back button focus method, which uses the AEL/AFL button to activate focus.
Tip 5 Keep your batteries warm!
The capacity of batteries highly depends on the temperature. Working in cold conditions the battery life is much shorter than usual. Therefore I have always one battery close to my body to keep it warm, mostly in my pocket. In case the battery in-camera is dying I can use the one in my pocket.
In case you are shooting several motifs during the day and would like to sort them right away, OM-D cameras allow you to make folders in camera. When your motif is changing you can change the folder and therefore the images are sorted when you are coming home. Depending on your workflow this could be very helpful.
How to make a folder
The easiest way to reach the settings menu is as in most cases the Super Control Panel. While shooting the Super Control Panel is reachable via the “OK” button.
1In the Super Control Panel you can choose the small card symbol in the lower-left corner. Press “OK” to open the settings menu.
2 Choose the option “Assign Save Folder”. You can choose here wither to make “New Folder”* or choose an “Existing Folder”.
*If you would like to make a folder with your computer, please take care that this folder is located in the folder “DCIM” and that the folder name has the structure 101OLYMP otherwise the camera is not able to find it.
3 In case you would like to make a new folder, the following dialogue allows you to adjust the number of the folder. An own name is not possible.
On the same place, you can select the folder you would like to save the images. Please be aware that the replay mode can only show the images of the chosen folder. In case you have more than one folder you can move images by pressing the “OK” button in the replay mode.
Shooting in the studio is more comfortable when you can save images directly on your computer and not on an SD card in the camera. It makes your workflow faster, as you can check image quality on a much bigger screen and you can post-process images on the go. No time-consuming transfer after the shoot is needed.
How to set-up wireless tethered shooting
Before you can shoot wireless into your computer you have to link your working computer, wireless network, and camera. Therefore you have to connect your camera with the provided cable to the computer and start Olympus Capture. This procedure is only needed the first time you are using your camera with the computer the first time. Once done no cable is needed. For linking computer, network and camera do following
1 Open Olympus Capture and press the plus close to “Create new link”
2 Connect your camera with your computer via cable and start. As soon the camera is started a selection menu shows up. Select camera control (tethering icon)
3 Select your computer name in the dialogue popping up.
4 Once the link is established you can disconnect the cable and start shooting with the camera.
In case you would like to reconnect your camera with the computer. Press WiFi Icon on camera and select “Access Point Connection”. Select then the network, which is used by your computer as well.
Differences to tethered shooting with cable
There are essential differences between shooting to your computer tethered with a cable or via WiFi. The most obvious is that in case you are using a cable you can adjust any setting on the camera and with the computer, whereas with WiFi the camera is in your hands and operation is only on the camera. For the same reason with the WiFi connection, you get no live view on the computer screen. WiFi is only transferring the image directly to the hard disk on a selected folder.
