Yes, it was a little foggy above the lake. Nevertheless, I was also able to get a proper image when I held the camera in landscape orientation, that is also a bit strange. I never use filters except of ND and CPL. This were images completely without filters.

Wouldn't it be 42MP/1.5 = 28MP after the crop? Still better than the A9 and A7iii. I know using aps-c mode is giving up a substantial amount of resolution, but it still would be a pretty substantial data set. (Edit: didn’t see Fred’s post when I made my comment. Didn’t realize that the MP need to be divided by 1.5 x 2 for the crop. 18 MP is a pretty big hit compared to 42, but it still isn’t horrible. Certainly might work for situations where resolution usnt critical.)
And you are still getting the 1.4 light transmission, so low light performance isn't compromised in any way. The effective DOF would be diminished somewhat (to around 2.0) but not too bad. Seems like a relatively modest tradeoff for such an increase in convenience. Not to mention that the 35 1.4 lens is substantially larger and heavier than the 24 1.4.
I think it would be kind of interesting to compare the performance of these two options in the manner that Fred does for other lenses just to see what kind of performance hit, if any, one might see using the 24 in aps-c mode compared to the FF 35 1.4. I don't know how to do this kind of comparo but I might take a stab at it just for fun. ...Show more →
18 or 16, not a big difference, but 42 and 18, that huge. I remember my A6K looking better than my 7R2 in S35.
You're not getting all the light of the lems because you essentially have less than half the sensor in use, so you're collecting less than half the light.
Like I said, S35 mode is there mainly for video use, it avoids the pixel binning and/or line skipping Sony are doing because they can't read 42mp 25/30 times per second.

Thanks. I agree, using the lens in crop mode would undoubtedly sacrifice a lot compared to a FF version for still photography. Perhaps too much. I guess I am just curious as to how significantly that sacrifice translates to in real world images.
Question (for my education, if anyone is willing): Is there any technical difference (such as effective dynamic range, DOF, high iso noise) between acquiring an image on a high res FF sensor in crop mode vs acquiring the same image in FF mode and then cropping the FF image to the exact same boundaries as the image acquired in crop mode? Are these technically identical images or fundamentally different?

If the final output is mainly resized images for the web and there is no further cropping, the difference should be hardly noticeable. Think of it as the difference between shooting with a A7III vs A7RIII.
Now, if you are shooting highly detailed landscapes and printing large, that's another story.

The images will be identical.. Crop is crop...being in-camera or in post.

Thanks. Very helpful. Confirms what I thought was going on.
Crop mode is only available in JPG as far as I know. So if you want the best image quality, shoot RAW and crop later.
BTW a 1.5x crop would bring the A7rII down to a resolution of 5301 x 3536. Printing at 300ppi, that's still like 18" x 12", and at 200ppi it's around 26" x 17". Totally doable to use the 24GM as your "35mm" if you have an R body.

Nope. Crop mode is available for RAW (compressed and uncompressed)
It can also be assigned to a custom button in latest bodies.

With the A7RII, crop mode (APS-C S35 shooting) works with RAW but not as a custom button. Try it out.
So, with older cameras it's cumbersome as we need to activate this function in the menu system.
Curious, what does activating Zoom on the III series cameras do when in RAW? Is the RAW file the same as no zoom? Or does it actually provide a smaller RAW?
BTW, like I said, Zoom can be assigned to a custom button on the A7rII, but it doesn't activate if you try it while in RAW mode (gives an error). I just tested it out on mine.
EDIT: Oh, I see, we're referring to two different modes (APS-C vs. Zoom aka Clear Image Zoom).

"Zoom" is totally different than APS-C mode. The former only works with jpegs and it's more useful for video.
The discussion is about APC-S/Super 35mm mode which is compatible with RAW and works with your A7RII as well. (without the possibility of being assigned as a custom button though)
Interesting, I didn't realize APS-C mode actually gave you a smaller RAW file.
Sorry for the long OT. To get us back on track, here's a shot from the 24GM (uncropped of course :P). My coworker here is playing with my CV180 while I tested his 24GM. Wow, the bokeh is smooth, not a single onion. Might have to give in and pick this one up. Click here for full size.
I shoot my big runway shows in crop mode . That’s about 20k images in a few days. It’s all shot using Raw compressed. Reason being I don’t need 42mpx as that’s way overkill as they only need a 9x12 300 dpi max for printing . Second I need a 300mm. Somehow Sony forgot to make one. I use the 70-200 in crop mode . Third I’m processing them from Raw to jpeg to load onto smugmug for them to purchase prints and even the buy downloads. This is good money for me. Last show I rented the A7III and used that at 11mpx and it held up very well. I’ll do the same in January. It’s a very useful feature. Now I have tried to purée it like 50 percent in Capture One and again that held up very nicely as well. Now I know it’s a big drop from 42 but for certain things it’s very useful. One thing for sure processing 20 k in 42mpx files I’d be on it for days. What I do is process about 2k at once in bulk. I custom WB and make a few adjustments and apply to all and hit the process button and go take a short walk. Or I’m uploading at the same time.
I've been waiting for Sony to release a 35mm 1.8 so I can buy a second A7III - got a 85mm 1.8 glued to the first one. This lens though... It seems to open up some new possibilities.
In theory, a 24mm 1.4 on an A7RIII in crop mode would look about the same, right? Has anyone spent some time with this combination in crop mode? I mostly do wedding work and I can live with 18mp, but I can't compromise on AF. The ability to zoom out to 24mm would be a nice bonus.

I am also curious about the same thing - I have been on the hunt for a fast and small 35mm AF lens, and this might be the best bet.
So far, I want to say yes - Fred has said the 24 GM cropped has different rendering than a 35/2.8 or cropped 24/1.8, so that is promising. The lens should act as a 36/2.1, with a slightly different FOV (difference between cropping to 35 from 24 vs. starting at 35 to begin with).
I love the assignable button to jump from 24 to 35 easily (I have an A7Rii), aperture ring, and AF/MF toggle - all very helpful in the field to capture the shot you are thinking of.
My Loxia 21 already doesn't see as much daylight as it should because I enjoy the walk-around aspect and rendering of my CY 35-70 - I could swap it out with the do it all GM and probably see more use out of my wide angle.
