Try the same test in low light with a lot of shadows. You’ll notice that ISO6400 is about the borderline of usability for both. Or in fact for most cameras on market.

I like your channel, but this could not be more of a an “apples vs oranges” comparison.
First, using the same f-stop for both cameras gives the K-1 about a stop of extra exposure (and hence noise advantage).
Second, you cannot compare 1:1 (100%) views of a 36MP image with a 26MP image. The magnification is higher for the 36MP image and hence more noise will show (just like more noise shows up when you change from a “Fit” view to “100%” view).
Third, the K-3 III uses internal image processing to beautify the raw data. One the one hand, one could argue one is only interested in “out of the box” comparisons, but on the other hand one definitely does not get to compare the sensor performances as such and could easily justify some significant post-processing for the K-1 images in order to provide a level-playing field.
All of the above has nothing to do with “scientific comparisons”, not every investigation has to meet every possible standard, but what you are doing here is unfortunately not meaningful, even though the comparison superficially looks like it is “fair”. However, please continue making videos about Pentax equipment.

Thank you for this video. As you said, it’s just a comparison of “first glance results,” but I still found the comparison to be interesting. I would love to see a similar comparison with the KP and K3III. Thank you again for your content!

I’ve been shooting sport with the K3iii but took the K1 to a darkly lit concert and was happy I did. When thing are moving fast, I’ll no doubt need to crop later and the K1 definitely lends itself to that. While I take a hot in sharpness, I can clean images from both at ISO 6400 and they look very good. I normally don’t shoot past 6400 unless the lighting is just that bad and I need a faster shutter.

Interesting video, surprised the K-3iii holds onto colors so well. Wonder how it does that.

Thank you. Very interesting content! I know how my K-1 compares to my K-5 II, so now I have an idea on how the k-3 III would compare to the K-5 II.

You might already know this, but F/4 on APS-C isn’t exactly the same on Full Frame. That being said though, I did hear that it was more of a “first-glance” results kind of video. If anyone wants to know definitively which camera has less noise, this is a factor that might need to be considered. but then again, the image size is different so I’m not concluding anything instantly because it might take me some time to think about. Also, there might be some factors that I’ve failed to recall that might be effective. That being said though, thank you. I’m not disagreeing with the video, simply trying to let someone who might be wondering, to know how this works.
