Hi! I'm owner of some Pentax film cameras: Pentax MX, Pentax ME Super and Pentax P30. A recently purchased the Pentax K3, my first DSLR and my start with digital photo. Because I'm owner of film cameras I have some manual lens, Pentax-M Series. I know that in Pentax is possible to use all lens from film era with digital cameras. I always use the
M Mode. I would like take the control.
I read the manual, and I set the: "Use Aperture Ring"to "Permited" in
Custom Setting Page 4, but I still found a issue: the photometer / light meter appear do not works.
Looking for a solution I found in Internet with help of our frind Google, the need to use the Green Button, another button that the manual does not explains very well your function, operation and use. Apparently the green button take the correct exposure and configure the camera. At the first time, the Green Button for me is not very confortable, I will prefer to use the classic shutter button halfway. Looking for an alternative I found that is possible to use a old school with the "
Preview Dial". If the
Main switch isset to Preview Dial, then is possible to
change the Aperture Value using the Aperture Ring from Lens and the
Shutter Speed using the Front e-dial, and the
photometer / Light Meter is working to adjust like old school.
In my search for how I can use the Manual Lens in the Pentax K3 and how is possible to use the light meter / photometer I found that is need it to configure the Green Button from
PLINE to
TV Shift on
Camera Options Page 5 --> E-dial Programming. This configuration I do not understand. I would like to undertand that the things do, I do not like copy & paste.
Can anyone help to undertand it? - Why is need to change this setting, TV Shift, for the Green Button?
- What it do?
- Is need it for all Pentax Manual lens Series? only for Pentax-M or Pentax-A or Screw Mount (M42)?
I think that change afect to when use the non manual lens if I want to use the Green Button. Its correct? What is the impact?
Exist somewhere explain very well the funtion, how to use or operation of the Green Button.
Thanks in advance!
