KP Max magnification in live view

ghl · 03-13-2021, 11:44 AM

I’m thinking of getting a KP and have a quick question for any owners.

I’m curious what the max magnification is when in live view,specifically with a manual focus lens?

I have a K-01 and the max magnification is 6x which makes it difficultto obtain specific focus with my 28mm and 35mm Taks.

I’m hoping the KP allows for more magnification in live view for thisissue. It wouldn’t be a deal breaker if it doesn’t, just curious.

Thanks in advance for the help.

Did a quick check, and it appears to go up to x16 (iirc 8x is 100%)

Thanks for the quick response, Robiles. I was hoping that was the case, thanks again for checking it out.

Happy to help. Also the Viewfinder / live view / video switch is genius, i will not buy another camera that does not have it.

To each their own, I like the button to switch between them on my K-1 optical viewfinder and life view better. But it's likely a matter of practice.

The k-3 and KP liveview switching mechanisms both work fine - I don’t see any real advantage to either.

As a former K-01 owner, the KP is awesome.

The only drawback of 16x on the review is that it is farther in the image than 8x is on the K-01’s 16Mp, so pixel peeping looks worse... even though the images are better overall...

Another advantage of KP is the second focus peaking mode (Extract Edge) which can make it easier to find focus. It comes from Ricoh GR cameras, and I believe KP is Pentax first DSLR with this function.

Here is a video on how it works on a Ricoh GR III. (I could not find a video from KP)

Past 100% (1:1 pixel mapping) any further enlargement is empty magnification. As noted above, that should be about 8x on the KP.

100% live view magnification on camera isn't 1:1 pixel mapping due to rear LCD having something like 1Million dots only (and 1M dots isn't even 1Mpixels). On my K1, 100% mag. in LV represent approximately what the image detail may look like on a 264 PPI print of the same image.

What does 100% mean in that context, if not 1:1, and why would that terminology be used*?

* A full answer might require some experimentation using a subject having elements of known dimensions and an image having known magnification.

1x means the image fills the rear LCD display. 2x means the image is twice the size of the display, 10x (what's also named as 100%) means the image is 10 times the size of the display. The display is 68mm wide, so, at 10x (100%) preview, the size of image features display is the physical equivalent to a 68cm wide print. It's not based on pixels, the LV magnification is how many times large is the image relative to display size.

So why would it be "also named" as 100%? (my question)

In PP, 100% means pixel-to-pixel mapping regardless of magnification. Is the rear LCD context different such that 10x never means 100% (pixel-wise) on your K-1 or are you saying it mean lineal dimensions?

FWIW...going beyond 100% would still be empty magnification.

The Pentax camera has its own definition of 100% , not the same as 100% on computer display.

Yes apparently. I don't know what 100% mean on camera, I believe it's just arbitrary because 100% doesn't correspond to the same magnification on all Pentax cameras, e.g 100% on a K3 doesn't correspond to the same magnification as 100% on a K1, even if both displays are 3" displays.

Of course there are different magnification on different cameras. The magnification depends on the resolution on the sensor, and the resolution on the LCD.
Cameras may using different resolution on the sensor, and may use different resolution on the LCD. So it will not ba a fixed number for all cameras.

But the only Pentax camera that I have used that has a 100% view setting is K3/K3 II (8.3x).
Are you sure that K1 has a 100% view setting? I doubt that it would translate into an even number such as 10x.

Edit: It seems that both K3 and K1 use a 720x480 pixel displays.

K3 resolution: 6016 x 4000 pixels
K1 resolution: 7360 x 4912 pixels

K3 6016/720 (1:1 pixels, 100%) = 8,35x
K1 7360/720 (1:1 pixels, 100%) = 10,22x

So if 10x in K1 is a 100% view, the actual magnification is 10.22x
