Love the Math photographer as he balances the line between science and feelings. Putting this here for discussion and a place holder when I have time to review.

WARNING: He uses terms such as Leica look, character and, soul.

;-)

Part 2 is more interesting. I list part 1 for completeness.

Part 2 with tests and summarization

Part 1 more of an introduction

I felt this comparison was too technical for its own good. A simple side by side would’ve been better.

This guys videos and comparisons are extremely technical, too technical for his own good.

He has these amazing cameras and lenses in his “studio”, and what does he shoot to compare? An action figure, wide open, in different exposure levels. So we can see how the raws from those cameras handle under exposure and pushing.

But we learn nothing about the character of the lenses, their sharpness through the aperture range and so on. I expected that, because I already knew the guy, so I just skipped around the video, until YouTube made further skipping impossible with their outrageous commercial punishment for doing so.

The thing that he is doing is well done, don’t get me wrong. I just don’t think it has much relevance for actual photography practice. The extreme pushing and pulling is something that basically never occurs in my daly practice.

The most interesting aspect to me, was the comparatively worse performance of the RF at iso 12.xxx and above.

Did he compare it at pixel level or at the same output size?
 
I like what Mr. Math does. His videos are different to the usual YouTuber review stuff. Most of 'em are also more subjective and not nearly as in the weeds as this one. I liked that he brought up the Leica Q's 28mm lens is wider than 28mm thing too. :-)

In my tests, RF's lens is similarly wider as is Q's.

I think his python script takes pixel dimension of the jpgs into account. I haven’t looked into this video in detail though, the script might be different than others.

I've been talking about this for a while - how the camera with no stabilisation and the lens least suited to low light work also has the worst high ISO performance.
Indeed, that seems less than ideal. The performance drops off in regions that you will easily reach, thanks to no stabilization and a slow lens.

The analyses are based on jpegs because that is what people use for social media posting, according to Math Photographer.

Be skeptical if you see a comparison of two cameras that use the same sensor tech, where the conclusion is that the smaller one is better than the bigger one.

I suggest positing a plausible thesis that explains the conclusion. If you can’t think of one, see if there is a simpler explanation.

I agree.
That’s not what he says. He says “technically”, in his measurements, the RF is the best of the three cameras. He calls it “the clear winner in metrics”. With the exception of high iso from 12k.

In his personal ranking the Q3-43 wins, because of Leica “look, soul and character” (thanks to the lens, their color science etc.), and still very good metrics.

What can I say, I completely agree with him. To me the Q3-43 is the better camera, thanks to the lens, even if it measures worse in “stress tests” that he does.

The measurements are in part edge cases, and there is a certain disconnect between his measurements part and the conclusions. It would have been better to really show off the character of the lenses/ color science. So I criticized the video, but I still agree with the conclusion. To me it’s really not that close bewtween the Fuji lens and the 43 Panaleica lens. I like the latter much better.

Between GFX100RF and Q3 43 the deciding factor is the preferable focal length. Between Q3 abd RF the OIS, aperture versus resolution and eye tracking AF speed, reliability.

Ergonomics is also a significant differentiation, and for some, the availability of Perspective Control. However, I like RF's form factor a lot.

Even something as apparently trivial as the aesthetic appeal of the curves and lines of a camera can be a differentiator for some. Or the presence of the Red Dot.

There's no accounting for taste.

I'm trying to make my mind up whether I should buy a used 50s Mkii. It has the same sensor as my 50s, so the same long exposure low noise and freedom from hot pixels, but a faster processor, a more streamlined, less bumpy and lumpy design, the current battery system and IBIS.

On the downside, I can't find a half case for it which I always find important for improving hand holdability, and £2.5k is a lot of money for me. I will also need to spend on new spare batteries which is annoying because I have just built my 50s battery collection up to 7.

It's the IBIS which is the main driver for considering such a purchase because it would increase the scope of the camera for hand held work with different non-stabilised lenses. i don't envisage MF as ideal for hand held work but there are always the opportunities either side of LE photos and I hate the idea of carrying a second camera for this.

I truly hope the more streamlined aesthetics is not a factor because even though the original 50s is a bit ugly, that shouldn't be a factor in a grown-up decision making process when resources are constrained.

Should it :-)

Interesting, David. I have large hands and the 50s Mkii, when I owned it, was very easy to hold in one or both hands.... similar to the 100S. It is the Q series and 100RF that seemed to need additional help for my paws.

No half case

Would one have to be a nutcase 😵‍💫 to purchase in orangy red.

Weeeeell I have a yellow such for my A7r2. Improves holding for sure for my sweaty palms, case not a proper fit though. Out in London nights I want people to readily tell its not a weapon, yellow helps in that. I've seen people trying to see what's in my hand when carrying all black camera nights in London.

I've seen a couple of comments by people with more technical knowledge than I possess, suggesting that designing a somewhat faster prime for a compact fixed-prime GFX100 might be more workable in a "normal" focal length such as 40mm or 50mm FF equivalent, akin to the Q3 43. A model of this type in addition to the current 28mm equivalent model would hardly be a novel idea to Fuji, whose GW690 and GSW690 "Texas Leicas" are legends in analogue MF.

A setup of, say, 43mm equivalent could give a "Nifty Forty" equivalent view at full 100mp medium format sensor coverage, and a "Nifty Fifty" equivalent view with 60ish mps of FF sensor coverage.

A design of this type might also allow for IBIS whether or not the lens was faster than F4.

Personally, I'm watching the skies and hoping for the day.

He also states that the RF’s native ISO is 100. My understanding is that 80 is for stills and 100 for video.
