Seeing a side-by-side comparison (and, even better, links to raw files) of the IQ3 tri vs achro on the same scene would be very helpful—thank you very much!

You already have a new car. And yes---both new cars and the IQ4 series are Dante approved.

Not sure Dante would approve of a Tesla Model 3. It has no soul. 
Dante's Inferno has plenty of souls :loco:

I am assuming no one actually spends 45k on this back. Most people upgrade which is like 22k-27k I guess depending on your dealer. Unfortunately phase don't like to publish pricing so its a bit of a shot in the dark which I honestly don't like.

Granted, P1 could make this easier, but it's not really a shot in the dark.
Where I am right now, unfortunately, I have no bandwidth. That's why I only show ScreenShots / JPEG.
I set the focus manually, exactly on the rain gutter.
Camera was XF with a Schneider Kreuznach 45mm F3.5 LF BR lens. Both backs have the respective base ISO. The pictures are not edited.
33% comparison
100% comparison
The shape of the roof shingles in front of the head is basically flat from our point of view and is essentially described only by the tonal values. The roof shingles separate much better in achromatic image.
300% comparison
At the roof gutter is a groove. The groove is not visible in the Trichromatic image.
Two other cutouts 100% and 200% from the motif.
Trichromatic image converted into BW in comparison to the Achromatic image.

Realizing the sweet spot is never cheap. Sometimes it is realized after spending a lot of money time and time again through replacement or upgrading. It really doesn't matter in the grand scheme of things.
There is always something or someone at the pinnacle of whatever endeavor and it is always questioned. Besides a topic of conversation, those questions mean little, and for me, I always love to have something out there for aspiration as well as inspiration.
What a boring world we would live in without those excellent icons to enjoy through acquisition, renting or simply observing. My appreciation goes out to all the Phase One customers. Not to mention the dealers and the corporation itself!:thumbs:

Actually it's about the same price. Don't ask me how I know... :banghead:

“These images are not edited” means you left c1’s raw image adjustments at default?
If so, re sharpening during such fine detail comparisons, I suggest lowering the threshold of sharpening to 0 and luminance noise reduction to 20 or under. Or in the very least exploring these settings and their impact on fine detail.

Yes, I could do that.
But the background is, I just made these pictures for myself to see what comes out of differences by default. The pictures were never used as a comparison for a forum or similar thought.
Apart from that, I think most users here in the forum know exactly what IQ3100 can and what you can get out of the post.

Absolutely. I only point it out because the difference seem quite significant at first when, with adjustments to how each are processed to get the most out of each, the difference is a bit more subtle. I'm glad to sell a ton of IQ4 150mp Achromatics (or IQ3 100mp Achromatics which we now have coming in as trade-ins) but I want to make sure potential clients have a realistic view of the amount of improvement they should expect in terms of sharpness, noise, and look. There is absolutely a difference, but it is not quite as large as the default raw settings will lead one to believe.
We jumped from the IQ180 to the IQ4 and frankly the difference is huge. I'd expect the move from a IQ100 is less as has been shown. Mostly using it on a Tech camera and the new sensor's minimal and at times almost imperceptible color cast from shifting is extraordinary. Still shooting LCC's for dust and falloff, but we are thrilled. HDMI live view and live focus peaking has made usability much better, both significant assets to a Tech camera user. Once Ethernet comes on line and some of the other projected features it will in my mind be the best back they have ever made. Making incredible huge B&W prints (don't have the Achro), preferred to have the flexibility of shooting color too, frankly can't see why the Achro is necessary. Wishing for a bit better battery life. No regrets whatsoever.
