How do you change Aspect Ratio on K-30?

Surely the K-30 has more than one Aspect Ratio available? I just noticed the LCD image does not fill the area. There are black bars at the top and bottom. I have searched the Menus and Manual with no results that I can find. Can anyone point me in the right direction? Thanks...Dan

Afaik, You can not change the aspect ratio on a K30 or for that matter any of the Pentax DSLR's.


Maybe what you are wanting to do when you are reviewing photos you have taken in camera is zoom the photo. I believe all you need to do is while looking at a photo on the LCD screen is to move the rear dial on the camera.

That's because the sensor captures the image in 3:2, but the screen has a 4:3 aspect. You cannot change the image aspect ratio, so there's no way to get rid of the black bars.

However, the K-3, K-3 II, K-S2, and K-S1 all have redesigned 3:2 screens, so playback / live view looks a lot nicer on those cameras. Here's a comparison of the K-5 and K-3; notice how there's no black bar below the image on the K-3:

On a slightly/completely different topic, i've heard the k-30 has "select-area expansion function for enhanced tracking of moving subjects" - where is this and how do I find it? Manual pg. number is good enough. I've used the k-30 for two years and didn't know this was a thing.

When [Expanded Area AF] in [AF Settings] of the [A Rec. Mode 2] menu is enabled, if your subject briefly moves out from the focus point that was selected when the focus mode was set to k (or when [AF.A] was enabled), the camera will continue to focus on your subject based on information from the focus points (back-up focus points) surrounding the selected focus point. The back-up focus points are displayed in pink on the status screen.
I believe it only works when you are using Select AF point.

No idea, I don't have a K-30. Just looked up the manual online and did a search...

So all think the K-30 can only produce one Aspect Ratio. I can now quite trying to change it. I thought with some Canon cameras more than one AR was available. Maby to do that would be confusing to the penta prism viewer. My others were point and shoot. Thanks all for settling the issue....Dan

I don't think that the aspect ratio has anything to do with the prism and the view finder. As Adam said the sensor is 3:2 but the LED screen is 4:3 (or was 4:3). When you are looking through the viewfinder, you are looking at a mirror that is reflecting the image from the lens. If you go to live view and look at the LCD screen, the image on the screen is straight from the sensor. Now, because the LCD screen is not the same ratio as the sensor, you will get an area that does not have a picture on it (letterbox) just like watching a widescreen movie from a DVD on a square screen TV. Pentax changed the LCD screen on the K3's and the K5's so that the ratio between the LCD and the sensor matched.


It could be possible that you can change the ratio on some Canon DSLR, but I wouldn't know about that because I have never owned a Canon DSLR. My guess would be, if you can, it would be the full frames like the 5d that has that feature.

APS Film cameras offered cropping to different aspect ratios. I recommend the Nikon Pronea 6i.

I don't know of any APSc digital cameras that offer in-camera cropping for different aspect ratios.

Some do but it might be a case of only offering different aspect ratios in live view mode. The K-01 offered multiple aspect ratios but it obviously only has live view mode.

If it is for filming, you maybe can do like a friend of mine did when shooting short-film: hook your device to a TV, put some ducktape on the screen where the black bars should be (so you only see what you wanna see), and then add the real lines in post-prod. 10/10 confirmed that works great
