Ok, did my best to get some comparisons of the A7CR+40G against the Q3 43. These were all shot at F2.5, ISO100, matching SS, WB set to 5500K. Imported all into Lightroom with the Adobe Default profile, then export at 4K to make file sizes more manageable. I'll provide a link to the RAW files here shortly for those that prefer that.

The Q3 43 images are the first ones of each pair, then the A7CR. Sorry for not more color options, I live in high desert Central Oregon so all we have is dull brown and dull green right now

They look a lot closer than I would have thought. Thanks for this.

The Sony definitely pops the yellows a lot more, but other colors aren;t as drastic and even more close together. Yellow is just the only color I could find today .

I’ll try and get an example of better specular highlights too, that’s probably the best differentiator between the two. Though still closer than you might think.

If you can, take a picture of a car or large object from some reasonable distance with subject separation and background bleh. I found the Q3 43mm to excel at mid-distance photography for people where you have some real subject separation pop. I'm not sure the flowers and plants comparison is representative of the differences between these two lenses.

Good comparisons and few differences that are immediately apparent to me. Sometimes, without my being able to say exactly why, I just like the output from one lens more than another. It might be interesting to put up a series of photos from each lens that are not identified and then to see whether one is drawn more to one set of images than to another.

Thank you for these images, I know how hard it is to do. There are significant differences but many are swamped by the differences in exposure - may be transmission differences as you used the same f-stop, or the light changed on you between sets.

Given how hard it is to set it all up, one suggestion is to simply take a set at different apertures besides the lowest common denominator - say, f4 and f8. You gain a better and more representative picture of how we typically shoot such material, at the best apertures.

These are all, effectively, bokeh images with missing middle ground between the near-focused object and the distance. A higher vantage point will help here. You can, after the setup, also do a set focused at longer focal distances - say 3-4 metres; these look to be about one metre or so. What you gain here: you instantly see foreground bokeh and focus fade in both directions.

Nature shots work well because you see image motifs of different sizes, with high levels of tonal grading and color gradation as well. Cars, buildings etc. posterize as they have a uniform color tone, so you only have the light to provide gradation. It's why most lenses handle that subject matter well.

It's critical to be mindful that you are seeing only a smidgen, the merest of looks, at what each lens is capable of and may be trying to do. We all need an overall balance of image types - light conditions, apertures, focal distances, image contents, angle of viewpoint all play a huge part and this is the reason to try to get as much done in one set as possible.

It also helps to choose representative setups of what you intend to do in real life shooting, your familiarity will help you see differences, and it will matter more to you. Last point: it is critical to equalise exposure of the white point at least, both WP and black points are best, so you can see shadow detail and highlight detail retention. Exposure changes everything.

PS these both focus to 0.25m so a close focus set would be great as well, you can do this indoors - very 'illuminating', often.

PPS you don't need anything more than 1500x1000 jpegs made for the project, images are gestalt objects. We need to see the interaction of the motifs - the 'flow' of the image - unless you lapse into 'surveillance mode'. No one puts 100% crops on their wall (I hope).

PPPS 'Looking through' the bokeh effect, I prefer the Leica here, better color response and color tone spread, more longitudinal 'life' esp. water, greater subtlety. But it's now hard to buy a poor lens, and the Sony did well too. And it's very personal. thanks again!

I let a friend borrow the A7CR long term so these are the only images I’m going to be able to share for awhile. Sorry to everyone wanting more.

I know people love comparisons and I don’t unappreciate them myself. But…

IMHO, ANY modern camera is capable of fabulous imagery. Unless it’s for print, I can take any camera I own from a 1” to miniMF and get interesting photos, as long as I’m shooting well. The most important tool is the one holding the camera. I peruse the m43 forum image threads and there’s some incredible work there.

And unless it’s out of spec there are no bad lenses. They can be sharper or crisper or gentler. Blur varies but there’s no such thing as a bad modern lens. It’s just lens personality and preference. Some lenses do better with different subjects. No need for a portrait lens to have ultra sharp corners. there are a few lenses I own that if I pointed at any woman I’d likely get a punch in the nose, they’re so sharp.

In 2026, IQ is a given. Has been for a while. For me, the only thing that matters is lens selection, functionality, handling and UI. That’s it. Maybe for some read out speed. The Sony 60MP sensor is in about 7 different cameras. There’s no doubt the A7CR and Q3 have very similar IQ when the sensor is basically the same. But I just can’t love the lousy EVF and sos so handling of the A7CR. I’d rather take the larger A7R5/6. I could do 90% of everything I do on my SL3 (my favourite small format camera) but I am baffled by Leica’s idiotic decision not to have EFCS available on their cameras. But I’ll still choose the more expensive SL3-P over the S1Rii. Handling and UI are essential. IQ is a given.

Jump into this thread since my 1st try to buy a used Q3 43 failed locally today - seller didn't show up and blocked me. Perhaps he thought I should make better usage of my Sony

Q3 (either 28 or 43) is such a camera:
i) A compact body with top-tier resolution and good user experience
ii) A compact lens with top-tier image quality

I tried hard to find a Sony combo as an alternative but failed on both sides:
- A7CR is the only body choice but its EVF/LCD is far from good to me
- None of Sony's top-tier (GM) lenses are compact enough; they're all fast and big like Canon/Nikon.

Finally I realize it's impossible to find such a combo without big compromises - I don't expect A7CR-2 to have significantly better EVF, and it's also very unlikely that Sony will release a slower&smaller GM prime (any of 28/35/40/45mm f/2).

If I get a used Q3 43 later, I'll use it together with my Sony 20-70-200, but it'll be my main daily carry.

Hope it's relevant here.
