DA* 16-50mm underexposes?

I took a couple of pics of the same subject in my room - mixture of fluorescent and incandescent light.

With my FA35, the image comes out brightly and well exposed

At the same aperture of f2.8, my DA* 16-50mm is noticeably dimmer and more yellowish in light cast.

Perhaps someone will be able to help you if you show us your pics?

typically people have this problem when they are shooting in P (or in your case possibly AV) mode and they have their camera set to spot meter. If you move your camera slightly it wille expose the image entirely differently.

Without seeing your images and your exif it is impossible to say. All I can tell you is that my 16-50 does not under-expose.

Da* 16-50mm f2.8 does underexpose like many other pentax lenses. However, it is not that severe most of the time.

This zoom does cast yellow tone to many things. I call it warmth giving zoom. Great lens to use in cool colour temperature environment and bringing out contrast the best. Hence this is the reason why this zoom performs so well in landscape or waterscape early in the morning.

Have you tried manual white balance with a gray card or something similar?

If you shoot in manual mode, you can get perfect exposures with the Da 16-50 or any other lens for that matter. Just expose as far to the right as you can without clipping highlights. My Tamron 17-50mm would "underexpose" too if I left it up to the cameras more automated modes. Problems like this are a great impetus to become proficient with M mode if you ask me.
