How to change aspect ratio in K-7

Hello guys, I am trying to figure out how to change aspect ratio in K-7. I think I changed it to 16:9 a while ago to have a landscape photo fit into my laptop screen perfectly. But it is weird for portrait, which I do a lot too. So I'd like to change the ratio back to 3:2 or 4:3, but I couldn't find where to change it. I am about to go on a trip. Can somebody help me please? Thanks.

It doesn't have aspect ratio for still photos!

It does have it for movies, however, which you change as below:

Menu button to Screen "3"
"Movie"
Right button to "Recorded Pixels"
OK button
Up or down button to "aspect ratio" you want.
OK button
Menu button twice to exit.

For stills, just about all DSLRs have an aspect ratio of 3:2, while point-and-shoot cameras use 4:3. On Pentax DSLRs, there's no option to just use part of the sensor and end up with a different aspect ratio, as the viewfinder would be unable to show you what part of the frame is in use. If you want a different aspect ratio, you can always crop in post

Thanks a lot for information. I just got back from the trip. No internet there...

I got it that there is a fixed aspect ratio for all still photos on my K7. So is that ratio 16:9?

JSJ - Further to what Adam says above, according to the K7 Manual (I was looking to buy a used K7 to get pentaprism for manual lenses - and then Pentax kindly invented the K30...) - you can change the Resolution of JPEGs, not RAWs, in the K7. But not - for actually taking images - the AR.

But - the K30, in Playback, can crop to ARs other than 3:2 - select 16:9, 4:3 and 1:1.

Can't find on a quick look at the K7 Manual if K7 does that - but if it does - being the top-end model, with more settings - might it be possible that you inadvertently "pre-set" that function to convert all JPEGs and "Save to" 16:9....?

Crop to different AR is on K30 Manual Pages 187-188 - but K30 doesn't have a "sticky pre-set" to continue doing that - it's a 1-off per selected image.

Only wondered about a "sticky pre-set" in the K7 - because my Bridge Fuji HS10 does exactly that. You can pre-set say, 16:9 - then if you pan images on a levelled tripod - makes them easier to create "even" panoramas with Hugin or other panorama programs.

Regards, Dave.

It's a quite simple crop in Lightroom. Just click on the crop overlay tool and then click on the aspect ratio and set it in custom to 16:9. There are several preset choices also but 16:9 isn't there although I'm running Lightroom 3 and ver.4 may have it.

I always gloss over that part of the manual, so I was surprised to discover that the K-7 has a similar set of features. That is, in the Playback mode, you can crop, and choose aspect ratios to crop to, rotate, etc. The cropped result is saved as a different image. That's on page 239-240 of the K-7 manual. The camera doesn't seem to have a way to apply this to many images at once or a permanent mode for it, which makes sense. Since the optical viewfinder always shows a 3:2 aspect ratio, framing something else would be a guess. With an electronic viewfinder like the Fuji HS10 has, it makes more sense... if you're one of those unbelievers in The One True Aspect Ratio Of 35mm Film.

The camera can't get stuck on a different aspect ratio, but it might be stuck on one of the weird digital filters. Check the [Memory] section in the [Rec. Mode 4] menu, and hidden on page 2 (turn the e-dial to get page 2) there's a check box for Digital Filters. Uncheck that if it's selected, then hit the MENU button twice to get out of the menu, then turn the camera off and on. Now the camera will have forgotten any unusual filters it was remembering. Page 281 of the manual. The factory default has this memory turned off, and I would leave it off. It seems like a good way to get a hundred shots inadvertently taken with "Toy Camera".
