IP54 Posted October 16, 2023 Share #1 Posted October 16, 2023 Advertisement (gone after registration) Hi all, i'm thinking to buy the Q3 to upgrade from my beloved Q typ116. I wasn't interrested by the Q2 due to it's high isos bad performance compared to the Q. So i'm wondering if someone here did a side by side comparison between the Q1 and Q3, same photo at 6400, 12800 isos and more? And then pushed by 2 IL in Lightroom to see if the banding is controlled. If you made or can make this comparison, could you please show the result in images please? Of course i know there are other benefits in the Q3, AF, resolution and tilt screen, but here i'm wondering about the sensor limits in bad light conditions Link to post Share on other sites More sharing options...

Because of Q2's higher resolution, it is essential to compare at the same output size and not at the pixel level. How did you come to the conclusion that Q2 is worse at high ISO? 1 Link to post Share on other sites More sharing options...

The OP's statement is contrary to the test reviews I've read. Link to post Share on other sites More sharing options...

Honnestly it's perhaps a bad memory from the Q2 release Now my interrest is on the new Q3 vs my Q typ116, regarding the high iso noise and banding, if someone did a test?

Sparkassenkunde Posted October 16, 2023 Share #5 Posted October 16, 2023 Just a quick test with a night picture from my daily commute today, ISO 6400 @1/40 f2.0: DNG as imported in Lightroom: Welcome, dear visitor!

IP54 Posted October 16, 2023 Author Share #7 Posted October 16, 2023 Advertisement (gone after registration) Hi Sparkassenkunde As we discussed in private, i already saw banding on Q3 photos, especially on a 6400 isos night shot with pushed shadows. So i wondered if someone compared Q vs Q3 in this situation, to check if Q3 handles better the banding that the original Q? Link to post Share on other sites More sharing options...
Sparkassenkunde Posted October 16, 2023 Share #8 Posted October 16, 2023 Here is the picture we discussed privately before. It is a ISO 6400, 1/40s, f4.0 shot pushed in Lightroom by 2 stops. It is my only picture so far with banding. All my other pictures with ISO6400 show no banding - even if pushed by up to 5 stops. So I can't say anything about the cause in this case: Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

There is no issues or banding at all. The Q and Q2 weren’t cutting edge sensor wise when they came out. The Q3 is definitely amazing. If you want even better image quality shoot in M-DNG and you’ll get even better high iso performance. That’s what I use at night. Link to post Share on other sites More sharing options...

Just a wild thought... could it have something to do with the sensor reacting strangely to the projected lights? A bit like the banding you can sometimes get in viewfinders from LED light sources... 1 1 Link to post Share on other sites More sharing options...
Sparkassenkunde Posted October 17, 2023 Share #12 Posted October 17, 2023 That might be an explanation - but I unfortunately can’t make more tests, as the illumination has only been installed until last weekend - I would have to wait until next year. I will do some more tests in the coming weeks and try if the banding occurs again. So far I am more than happy with the real life use of the Q3. The example shown above was accidentally shot with the mentioned parameters, all the other pictures I took that evening were fine. Link to post Share on other sites More sharing options...
IP54 Posted October 17, 2023 Author Share #13 Posted October 17, 2023 it seems we are not alone observing this random banding, i just saw this in the Q3 facebook group Welcome, dear visitor!

Miltz Posted October 17, 2023 Share #14 Posted October 17, 2023 The banding is not from the sensor. It's from the lighting. Link to post Share on other sites More sharing options...
Sparkassenkunde Posted October 17, 2023 Share #15 Posted October 17, 2023 That was my thought as well. The comparison from the Facebook post doesn’t hold any information on the lighting situation, unfortunately… Link to post Share on other sites More sharing options...
Daniel C.1975 Posted October 17, 2023 Share #16 Posted October 17, 2023 (edited) Sorry to say, but there are too many people out there with too deep pockets but no clue (and the lack of will to learn) and totally unreasonable expectations. This combined with the possibility to publish funny statements or ridiculous comparison and findings on the spot is a deep well for false and nonsense information. I honestly perceive this as very tiresome. I am not addressing anyone in this thread, it is just a general statement Edited October 17, 2023 by Daniel C.1975 8 Link to post Share on other sites More sharing options...

IP54 Posted October 18, 2023 Author Share #18 Posted October 18, 2023 Well, back to my question. I've just have the opportunity to test the Q3 against the original Q, this test give the answer, 6400 isos, +2 IL, + 50% shadows, Q3 on left, Q on the right: Welcome, dear visitor!

MindsEye Posted October 18, 2023 Share #20 Posted October 18, 2023 (edited) I've had my Q3 since late June. I haven't noticed any banding at high ISOs and/or night shots, even with expansive skies or large areas of similar tone. I don't have a Q to compare. But I'll provide a high ISO example that is also on my Q3 gallery. Here is the overall image shot at dusk at ISO 12,500. Look at my next post to see detail at 100% as you can't see the noise or artifacts accurately with this one (scaled down for the forum posting requirements) Welcome, dear visitor!
