Q image ratio - which one is better and what for?

Did a little search on this but nothing came up in PF:

Image capture settings > Aspect Ratio: choice of 4:3, 1:1, 16:9, 3:2
It is presently at 4:3 (default).

What difference (i.e.: image rendering) does it make if one chooses any other setting here?

Thanks,
JP

Don't have the answer but I think its a good question. I was playing around with the Quick Dial and see that aspect ratio is one of the possible settings for it. I have each assigned a dial setting but would also like to know the pluses and minuses, if any, for each with the Q.

I don't even know where to start to assign anything to that dial ...

Let me know if you ever find out anything about the "aspect ratios" .
Thanks

aspect ratio's is the format of the picture you will be taking, one is a wide angle format for say your HDTV, thats 16:9, there is square format which is 1:1, 3:2 I think is a cropped version of the standard 4:3, probably wrong on that last one. But remember every time you change aspect ratio your MPs get bumped down. Changing aspect ratio is also good for adapted D-Mount lenses that don't fully cover the image circle.

Hi JP,

There is no "better", it's just cropping to standard film formats.


A cut and paste from the specs page:
[4:3] 12M (4000x3000), 9M (3456x2592), 5M (2688x2016), 3M (1920x1440)
[3:2] 10M (4000x2664), 8M (3456x2304), 5M (2688x1792), 2M (1920x1280)
[16:9] 9M (4000x2248), 6M (3456x1944), 4M (2688x1512), 2M(1920x1080)
[1:1] 9M (2992x2992), 6M (2592x2592), 4M (2016x2016), 2M (1440x1440)

Personally, I like 3:2 because I'm used to it -- I can mentally crop what I see on the LCD to my favorite print formats easily. I commonly shoot 4:3 because it's a little taller in landscape orientation (which is how I shoot more than 90% of the time if from a tripod), so I have a little more coverage if I want to crop vertically -- which is often. This is primarily by habit or convenience though, and with the Q, at arms' length with any of the Q system lenses, it's easier going from landscape to portrait, so I often set the front dial to control aspect ratio and switch to get the best crop in camera. 16:9 is nice for shots that emphasize either wide or tall (really nice with the FE for me). Note that all but the square use the full 4K pixels of the sensor width.

Bottom line, it's really just something else to play with. If it helps your photography, then use it. If not, just pick the one you like and ignore the rest as if they weren't available.

Also, to add to snostorm's great answer, if you shoot RAW, the aspect ratio in my recollection does not crop the RAW to anything other than full resolution in 4:3 factor.

Here's what I did - for now.

Menu Camera #3, then to Quick Dial
First setting is "Smart Effect" and there are LOADS of settings possible - 9 predetermined and 3 User defined. I have Vivid Color, Unicolor Bold (with blue selected at moderate level), Vibrant Color Enhance, and Bold Monochrome.

Then go to "Custom Image" and you have 11 choices. I have Bright, Natural, Vibrant, and B&W selected

Next you have "Digital Filters" with 12 choices including None. I've got Color, Water Color, Fish-Eye, and High Contrast selected.

The last choice is "Aspect Ratio" and you have 4 choices and 4 settings so it's 1:1 for the buttons. As you noted the choices are 4:3, 1:1, 16:9, and 3:2.

LOTS of choices and creativity in one little dial on the front of the camera. Brilliant!

Thanks Scott.
From what I saw on the computer monitor, the images look indeed "taller" than what I am used to with the K5 files (RAW).
I'll just play with it and see what happens, as you say !
Cheers!

With the Q, only JPEG so far to get used to the camera, but I shoot RAW only with the K5.

Indeed, 4:3 is the native ratio of the Q sensor, whereas it's 3:2 for the K-5.

Huge differences in composition and "feel" between these formats; I personally prefer 3:2, followed by 1:1, then 16:9, and lastly 4:3. 4:3 and I just don't get along well, so I don't use it a lot, although I dabble a bit now and again.

I recommend shooting for a week at each to get a feel for the different "feels" so you'll know when to apply them.

Lots of fun.

Another aspect of the Q where the front dial comes in incredibly handy. You just change on the fly back and forth as appropriate of needed.

Thanks a lot guys!

I'll "test" different ratios and see what happens.
I had forgotten that you could assign this to the front dial .... I haven't even tried this yet.
What's there on that dial as "default" anyway?

If I recall its set for all settings = 4:3

Thanks.

The only thing I saw, when I turned that front dial, was that the screen would show little coloured icons on the right (of the monitor), in capture mode.
It also seems to change the image hue/tone.

Like everything else on the Q, there are layers.

You can set the dial to do several things.

Go to Menu
Select Camera3
Go to Quick Dial
Press the Timer Button on the Right
Now you can change what function the dial serves by choosing one of the 4 options at the top. #4 is to change the aspect ratio. (#1 is the default and it's Smart Effect, #2 is Custom Image, and #3 is Digital Filters - each has 4 settings for a total of 16).
