Detail Information


Product Features:

This adapter can allow your use any OM mount lens in all of Canon EOS mount DSLR Camera.

With this new EMF adapter. Beside you can obtain focus confirmation red light, and bee sounds. You also can set the aperture infomation.

The camera can be changed on a dandelion aperture in interval from F1.1 to F45
The camera can be changed  on a dandelion focal length in interval from 1mm to 65535mm
Date can be save even turning off the camera
When focus is correct, there will be an indicator of red light and a sound singal that will prove chosen focus
You can use in Av or M mode.

　

Method for setting program:

 

1. Setting the maximum aperture on lens

2. Setting  the desired aperture on camera

3. Focus and meter the object, when focus is achieved.

4. Setting the lens aperture to the same desired aperture as the camera setting
5. Press the shutter button and take the picture.

And you can also:

1. Setting the maximum aperture on lens

2. Setting the aperture value on camera to maximum lens aperture

3. Focus and meter the object, when focus is achieved.

4. Setting the lens aperture AND the camera aperture setting to the desired aperture.

5. Press shutter button and take the picture

 

Shot and not recording exposure aperture setting

1. Setting the aperture value on camera to the lens’ maximum aperture

2. Setting the camera to AV mode

3. Setting the desired aperture on lens

4. Focus and meter the object and take the picture.,

Exposure aperture data recorded in EXIF is the lens’ maximum aperture.

 

How to Set Up this emf chip Adapter

1. Attach the adapter to the lens and attach the lens to the camera when camera is powered off. Power on the camera and set the camera to Manual mode. Set the camera in single shoot drive mode. Set the shutter speed to 1/60 second and aperture increment step to 1/3 EV.

Notice: Do not set the camera in continuous shooting mode to avoid misopertations. only set it in single shot

2. Turning  the aperture setting dial and set the aperture value to F/64 and press shutter button once.

3. Turning  the aperture dial and set the aperture value to F/57 and press shutter button once.

4. Turning  the aperture dial and set the aperture value to F/64 and press shutter button once. The operation combination of F/64-shutter button+F57-shutter button +F/64-shutter button will activate the setting mode of the ring.

5. Turning  the aperture dial, if the maximum aperture value can be set to F/1.0, your ring is now in setting mode. And you can begin to set the focal length, maximum aperture value and focus micro adjustment of your lens.

 

How enter values in setting mode?

When you setting up the ring, you will need to enter some values. In setting mode, the ring interprets specified aperture values to numbers. The conversion rule is stated in the beneath chart:

 

F/2.0

F/2.2

F/2.5

F/2.8

F/3.2

F/3.5

F/4.0

F/4.5

F/5.0

F/5.6

0

1

2

3

4

5

6

7

9

　

The ring has 3 setting modes:

Mode 0- enter  your lens’ maximum aperture.

Mode 1- enter your lens’ focal length.

Mode 2- enter your lens’ focus micro adjustment.

Turning  the aperture dial to specific aperture value and press shutter button to enter a desired setting mode.

For example, if you want to enter the lens’ maximum aperture, turn the aperture dial to F/2.0[which means Number 0 to the ring] and press shutter button. You are setting the ring in maximum aperture enter mode.

 

Entering  the maximum aperture:

1. Turn the dial and set the aperture to F/2.0 and press shutter button to enter this mode.

2. Turn the dial and set the aperture to the actual maximum aperture of your lens and press shutter button. The maximum aperture will be registered in the ring.

This emf adapter accepts aperture value ranging from F/1.1 to F/45.

 

Notice:

Don't set the maximum to F/1.0. This value is reserved for engineering purpose and will not be accepted by the ring.

Don't set the maximum aperture smaller than F/5.6. The focus detecting system of your digital camera might fail to function properly when a lens slower than F/5.6 is attached.

Store the parameters to emf chip

 

Enter the lens focal length

1. Turn the dial and set the aperture to F/2.2 and press shutter button to enter this mode.

2. Focal length can be set from 1mm to 65535mm. The ring needs five numbers to store the focal length data. If the focal length of your lens is smaller than five digits, you need to insert zeros in front of actual numbers. Each time you choose a number, press shutter button to enter.

Store the parameters to emf chip

For one example, if your lens focal length of your lens is 50mm, you shall enter 00050, that will be a combination of operations: F/2.0-shutter + F/2.0-shutter + F/2.0-shutter + F/3.5-shutter + F/2.0-shutter

 

Enter the focus micro adjustment

1. Turn the dial and set the aperture to F/2.5 and press shutter button to enter this mode.

emf chip accepts focus micro adjustment value, ranging from 0 to 31. The value is defined by two numbers. If the micro adjustment value of your lens is smaller than two numbers, you shall insert a zero in front of the actual number. Choose the desired number and press shutter button to enter the value one by one.

Store the parameters to emf chip

For example, if the micro adjustment value is 25, you shall enter F/2.5 - shutter button + F/3.5 – shutter button

Notice: Please enter the micro adjustment value according to your own tests. The value shall not be entered based on calculation alone.

 

Store the parameters to emf chip

When you are finished entering all the parameters of your lens, you shall store them in the ring for normal shooting. Here is how:

Change the aperture value to F/57, press shutter button once.

Change the aperture value to F/64, press shutter button once.

Change the aperture value to F/57 again, press shutter once.

If all the values you’ve entered are correct, the above three steps will store all the parameters you’ve just entered to the chip on emf chip.

If you have miss some steps in the entering process or the value you’ve entered does not fit the value range requirement stated above, the ring will automatically exit setting up mode and no parameters will be stored in the ring.

All the data stored in emf chip will not lost when camera is powered off.

The default parameter settings of emf chip is 50mm F/1.4, please change the parameters according to your lens’ specifications.


Take care:

1. Don't touch the golden contact points of the circuit board of emf chip when attaching and detaching the ring to your lens and camera.

2. Don't use F/64-shutter + F/57- shutter + F/64 – shutter combination in normal shootings. This combination will set emf chip to setting up mode. If you unintentionally enter this mode, choose a aperture value between F/6.3 and F/51 and press shutter button once to exit.

 
-----

1. Date is already saved anyways. You don't need the chip for that.

2. Has anyone really tried these instructions? That is a bit much but if it works, so be it. I am interested to know if these instructions work.
