MECAMAT 45-20
WEB INFO

The Metz 45 CT-1 is more useful in Manual mode if you can find  this part. Try eBay and/or I might have one in a kit with flash and high powered battery, I grab all I can. It adds an additional external sensor with more electronics and a myriad of settings

NOTE:  There are different versions for different models of the 45CT and 45 CL and they are not interchangeable. Metz has produced a number of different versions of the Mecamat for different models of the 45er. Mecamats can ONLY be used with the model they were designed for.    


BENEFITS

1) In Automatic mode it extends the number of usable Apertures to 9 instead of five.

2) In Manual mode it allows manual power setting in full stops  from 1 to 1/64 instead of full power only

3) It has a spot meter option. 

When the CT-1 flash came onto the market it represented a lot more power than most flashes available at that time and even today.

It had a large head, great light distribution, and in full manual settings took care of slow film better than anything else.  It effectively extends its usefulness to the present day. And with the Mecamat it can handle almost anything with the additional variables it performs.

WEB HINT - In the auto-mode you have 2 options, a green one and a red one... There is a switch with which you can select what indicator you are using.... If you set the red indicator to f/8 or f/16 and have the switch to green, you'll probably get overexposed pictures... But if the other way around (green on scale, red on switch), you'll get underexposed pictures... Mind you, you also have to set the switch at the back of the mecamat to the right side 


BACKSIDE VIEW

#14  On top is the left right switch. It activates either the extended automatic dial on the left side or the manual dial on the right side. A white indicator shows which side is activated. 

#15  Below in the middle is the flash ready lamp which replicates the flash ready status from the main unit. 

#16  Below the flash ready lamp is a red led which lights up shortly if there was sufficient light.

#17  Adjuster for angle of the sensor. At the bottom of the housing is a screw dial that allows to adjust the angle of the Mecamat upwards or downwards, in order to point the sensor when using the spot metering mode. 

#18  The unit will point downwards by using the adjuster and is designed for and perfectly suitable for Macro work, when the subject is very near to the camera.  The little red button on the hot shoe can be used to trigger the flash for a test shot. (#18 Grey in photo)



The front can be tilted to the side and the hole then acts as a visor so that you see where the Sensor is aiming. In the back a plastic part can be pushed out to be used for aiming with the visor.  You can see it in the next picture at the left side near the bottom of the case in its pushed in state. The sensor itself can be turned with its black plastic rim and then pulled out to give a spot metering effect.

NOTE:  On the right side is a dial that looks very similar to the one on top of the the flash itself. When the Mecamat is attached the dial on top of the flash is without function and it does not matter how it is set. 

ADVANTAGE:  The inner dial is used to select the ISO. The outer dial can be set from Manual full power to 1/64 power. For each stop the table indicates the flash duration time between 1/300 to 1/16000 of a second. The upper part matches apertures with distance for the chosen setting.
The highest ISO setting is only 400 but that does not matter as it is anyway only for informational purposes. A good shooter shooting digital will get the right power setting by test shots and can ignore the ISO setting completely.

On the left side is a second similar dial and a switch. The switch can be selected to activate a “green” or a “red" mode. Each mode represents 5 automatic apertures can be selected by turning the big dial. 

•   The “ red” mode allows lower apertures.
•   The  “green” mode allows higher apertures. 
•   The two modes overlap and one in the middle resulting in a total of 9 selectable apertures.
•    For ISO 100 the apertures range from 2.8 to 45. The scale also shows the maximum distance for each aperture.
•    Someone mentioned well it only goes to  ISO 400.  Duh!  
With a flash as powerful as the 45 who cares, I want as low an ISO  as I can use for massive clean files.  The ISO settings dial is just there to mechanically align the values printed on the dial. 
If higher ISO values are set in the camera simple adjust the aperture by the number of stops necessary.  Each doubling of the ISO means one stop, simple, a third grader can math that one out.
