    Exposure compensation with Neutral Density filter. Please help

    Hi there,

    I am a new owner of Konica Hexar AF.
    As you know, the maximum shutter speed for this camera is an unfortunate 1/250.

    I am planning to buy probably an ND4 or 8 for times when i need to do some outdoor photography. How do i compensate for this?

    I noticed the Hexar can only fo EV +/- 2. Does it mean that i can only use an ND2 filter? Please help.......

    Don't know the camera, but a quick check reveals you can override the automatic filmspeed setting (DX coding) and set the film speed manually. So ... ND2 filter needs 2x normal exposure, if you're using ISO 400 film, set the speed to 200. ND4 - set 100, etc.

    hiya fixbones, you could compensate for it in the film speed setting. if you were using 400 iso and a 8x ND which is 3 stops then you would put the film speed 3 stops down which would be 50 iso. Nd 2 is one stop Nd 4 is 2 stops and ND 8 is 3 stops. cheers, john

    Normally the ND (Neutral Density) filters are going in 1F steps:
    ND 0,3 ; ND 0,6 resp. 1 F stop; 2 F stops so I think a N.D. 0,6 for 2 F stops is a practical choice.
    With a TTL metering the correction is already there. Working with a seperate lightmeter simply compensate for 2 F stops.

    Example: 1/250S f=11
    --> 1/250S f=5,6
    or 1/60S f=11
    or 1/125S f=8

    Best regards,

    Robert

    (owning a ND 0,6 Heliopan for his enlarger for doing RA-4 prints for a regular exposure time of 10-20S)
    Can also match on the Leica M7 but the fastest shutter speed is 1/1000S.

    Reason i want to use an ND filter us because i would like to push my ISO 400 to ISO 1600 and i think i will be shooting 1600 most of the time.

    See if i am correct.......... so if i am shooting at ISO 1600. All i need to do is put on my ND4 filter and then set it to EV +2.0 and i am good to go...right? I can just shoot normally from here?
