Question 1

How to use the METZ MECABLITZ 50 AF-1 DIGITAL flash?

Accepted Answer

The METZ MECABLITZ 50 AF-1 DIGITAL is a high-performance flash compatible with Olympus, Panasonic, and Leica cameras (FourThirds standard), as well as Canon, Nikon, Fujifilm, and Pentax depending on the versions. To use it correctly, start by turning off your camera and the flash, then attach the flash to the accessory shoe by engaging the foot, and then turn the knurled nut until it is firmly locked.

Install 4 AA batteries in the designated compartment. You can use alkaline batteries (LR6), lithium (FR6) for better performance, or rechargeable NiCd/NiMH batteries (HR6/KR6). Lithium batteries offer better longevity (about 430 flashes) and shorter recycling times (between 0.1 and 5 seconds depending on the type of batteries and the setting). Once the batteries are installed, turn on the flash by pushing the main switch up to the “ON” position.

The flash primarily uses three operating modes. The TTL mode (Through The Lens) is the recommended automatic mode for most situations: the camera measures the light reflected by the subject and automatically adjusts the flash power. A good exposure indicator “ok” lights up for 5 seconds after a correctly exposed shot. The manual mode (M) allows you to control the power manually with 8 partial power levels (from P 1/1 to P 1/128). The HSS mode (High Speed Sync) allows the flash to be used with shutter speeds faster than the normal sync speed, ideal for portraits in ambient light with a wide aperture.

The LCD screen of the flash continuously displays the selected mode, the zoom position of the reflector (from 24 to 105 mm in automatic mode, with wide-angle coverage down to 12 mm via the built-in diffuser), and the maximum range in meters or feet. Wait for the red availability indicator to light up before taking the photo. The motorized zoom head automatically adjusts to the focal length of your lens, but you can also adjust it manually if necessary.

To optimize your photos, the flash offers several advanced features. The modeling light allows you to visualize the lighting effect before taking the shot. The flash head can tilt +90° upwards and -7° downwards, and rotate 270° horizontally, allowing for indirect lighting (bouncing the flash off the ceiling or a wall) for softer lighting. The flash exposure compensation (from -3 to +3 EV) compensates for dark or light subjects. You can also use second curtain sync to create motion blur effects, or flash bracketing to vary the exposure over multiple shots.

In macro photography, the flash has an automatic AF illuminator that helps with focusing in low light (range of about 6 to 9 m). Maintain a minimum distance of about 10% of the displayed range to avoid overexposure. The flash automatically goes into standby after 10 minutes of inactivity to save batteries, but you can quickly reactivate it by pressing a button or half-pressing the camera shutter. For maintenance, regularly clean the lens and reflector with a soft, dry cloth, and consult your camera's manual for specific settings for flash mode compatible with your model.

Question 2

How to unlock the head of the METZ MECABLITZ 70 MZ-5 flash?

Accepted Answer

Unlocking the head of the METZ MECABLITZ 70 MZ-5 flash (reflector) is very simple. In the base position, the reflector is mechanically locked for safety and stability reasons. To unlock it, you need to press the unlock button located at the base of the flash head, then turn the reflector either vertically or horizontally as needed.

Unlocking procedure:

Firmly press the push button located at the base of the reflector
While holding the button down, turn the flash head (reflector) either vertically or horizontally
The reflector unlocks and can rotate freely until it reaches the desired position

Available usage positions: The reflector of the METZ MECABLITZ 70 MZ-5 flash can be rotated 360 degrees both vertically and horizontally. For effective indirect lighting (for example, towards a ceiling or wall), you need to turn the reflector at least 60 degrees to the notched position. At this position and beyond, the distance indications disappear from the flash's LCD screen, which is normal as the actual distance (direct or reflected) becomes an unknown quantity.

Practical tips: Make sure the flash is turned off before handling the reflector. When using indirect lighting, aim the reflector at a neutral-toned surface (white ceiling or light wall) to avoid unwanted color tints. Wait a few seconds after a flash before touching the reflector as the glass may be very hot due to the intense light energy.

Question 3

How to unlock the Metz Mecablitz 70 MZ 4-5 flash head stuck at 90° on the side?

Accepted Answer

To unlock the Metz Mecablitz 70 MZ 4-5 flash head that is stuck at 90° on the side, follow these steps:

Steps to unlock the flash head

Locate the locking mechanism: On the side or at the base of the pivoting head, you will find a button or lever that is used to lock the rotation.
Activate the mechanism: Press the unlock button or slide the lever to release the head.
Gently turn the head: While keeping the mechanism unlocked, rotate the flash head to return it to the desired position.
Lock the head: Release the button or lever so that the head locks into the new position.

Tip: If the head seems stuck or does not unlock easily, avoid forcing it to prevent damaging the mechanism. Check that nothing is obstructing the rotation and that the button or lever is functioning properly.

Question 4

How to replace the NiCd batteries of the METZ MECABLITZ 45 CL-4 flash?

Accepted Answer

The METZ MECABLITZ 45 CL-4 flash uses a NiCd battery pack 45-40 that does not contain individual batteries to replace. If your NiCd battery is worn out and you wish to replace it with a new pack, here is the procedure:

Removing the old battery:

Press both locking buttons located on the battery drawer simultaneously
Remove the battery pack from the flash

Installing the new NiCd 45-40 battery:

Insert the new battery pack into the flash head
Push until you hear or feel the click of closure

Mandatory initial charge:

Before any first use, the NiCd battery must be charged for 5 hours. Locate the charging socket at the bottom of the battery pack. Connect the supplied charger or the B 45 charger set (ref. 0012045) to this socket. A light indicator next to the socket lights up during charging. You can leave the battery engaged in the flash during this recharge, but do not operate the flash during this time.

Important: Never place a NiCd battery pack in the optional 45-39 battery drawer. NiCd batteries have specialized contacts designed for their specific voltage. The battery drawer is exclusively reserved for manganese alkaline batteries type LR 6. Incorrect use could damage your flash.
