Question 2

How to open the battery compartment of the MECABLITZ 28 C-2 and access the different parts of the flash?

Accepted Answer

Opening the battery compartment: First, turn off the flash by pressing the O button. Then, push the battery compartment cover in the direction of the arrow indicated on the housing. The cover slides to give you access to the four battery slots. Strictly observe the polarity indicated by the engraved symbols when installing the batteries or accumulators. Always ensure to replace all four batteries at the same time and choose batteries with the same charge state.

The MECABLITZ 28 C-2 accepts four types of batteries or accumulators: NiCd type IEC KR 15/51 (offering the fastest recycling times and rechargeable), manganese alkaline batteries type IEC LR6 (for average performance), or Ni-MH AA size (Mignon) accumulators. Never use lithium batteries. After inserting the batteries, close the compartment cover by pushing it all the way.

Accessing the reflector and angle adjustment: The reflector is the most accessible part of the flash after the batteries. Hold the flash with one hand, then pull the reflector head forward from the housing with the other hand until it reaches the stop point. Once cleared, the reflector can be tilted vertically upwards by about 80 degrees, allowing the flash to be directed towards reflective surfaces like the ceiling for indirect and softer lighting.

Integrated wide-angle diffuser: The flash comes with a wide-angle diffuser that fits directly onto the reflector. To install it, place the diffuser on the reflector and press it firmly until it clicks into place on both sides. This diffuser expands the lighting coverage to allow use with 28 mm wide-angle lenses, whereas without the diffuser, the minimum coverage is 35 mm.

No other part of the flash should be disassembled by the user. The internal flash capacitor is a complex component that requires no regular maintenance. If you leave the flash unused for several months, turn it on for about ten minutes every three months to condition the capacitor and maintain its performance. For any repairs or replacement of parts beyond the battery, consult the manufacturer.

Question 3

Why do the indicators on the METZ MECABLITZ 28 C-2 not light up despite new batteries?

Accepted Answer

If no indicator lights up on your METZ MECABLITZ 28 C-2, even with new batteries, here are the essential checks:

Check the battery insertion

Ensure that the 4 AA batteries are correctly inserted with the right polarity (+ and - oriented correctly)
Use the same type of battery for all compartments: manganese alkaline batteries (IEC LR6), NiCd (IEC KR 15/51) or NiMH
Do not use lithium batteries, they are not compatible with this model
Replace all 4 batteries simultaneously, not just one or two

Correctly activate the flash

Press the I button to turn on the flash
The green operation indicator should light up immediately
Wait 1 to 2 minutes: the orange indicator (flash readiness indicator) will then light up

If the indicators remain off

Check the battery polarity again - this is the most common cause
Batteries may be depleted even if they appear new: test with other certified new alkaline batteries
Clean the contacts inside the battery compartment with a dry cloth to improve electrical contact
If no indicator lights up despite these checks and confirmed functional batteries, there may be an internal issue requiring professional repair

Tip: During prolonged non-use, remove the batteries to prevent them from discharging or damaging the internal circuits.

Question 4

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 5

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 7

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.
