It's quite late now, so I'm going to get some sleep and come back with a fresh head tomorrow
Thanks for helping me with this
What was your aperture on the manual lens shot?
Forgive me, but I don't have a Kx and I'm not sure what the bolded section means. What two settings does the green button have?
Reading icywindow's link shows the green button can be customized to meter when pressed. Interesting since it also says the exposure compensation (+/-) button will do the same thing. So, you have two buttons to do the same task.
To get your exposure you just need to be in Manual mode, turn the aperture ring to your desired setting, press your customized green button or the exposure compensation button, then take your picture.
You have at least three variables comparing these images:
- You changed lenses
- The first one has more of the largely white object in the center. The second one has a much wider view. If the scene changes, even a single lens could give a different exposure.
- The manual lens is metering center weighted. The kit lens is using multi-segment. So, not only did you change the scene, but the camera changed the metering mode that made it more likely the exposures would be even more different. Even if you didn't change the lens, this difference in metering mode could change the exposure.
Metering For The Right Exposure
And lastly, exposure compensation does not work in manual mode. You simply change the values of your exposure; ie change the aperture or the shutter speed.
[edit]I just wanted to add something about the different metering modes.
With your kit lens the camera can use any of the three modes. With a manual lens the camera can only use spot or center weighted. You could, to get a better comparison of exposures, set the camera to spot or center weighted, take a picture at 80mm on the Cosina, and then put the kit lens on, recompose for the same composition and take a second picture. Oh, and set the F Stop to the same value on both lenses. This way the only number that may vary is the shutter speed.
