p.2 #1 · p.2 #1 · A1 new feature: CIZ with AF-C and E-shutter now


I just briefly tested R4 with 200600mm + TC1.4x + APS-C + CIZ 2.0 on a brick wall across my street. Well to my eye FF or APS-C without CIZ cropped to the same level as CIZ samples provide less detail than Clear Image Zoomed brick

On the other hand - I also tested an indoor sample with my A9 and 14mm GM as it was mounted there, and in that case CIZ sample looked a bit ‘not so natural’ if compared to simple crops. Something like a bit overprocessed result in DeNoise or Sharpen.

Well, in any case, my idea was to see if 200600mm can be used, not the UW lens, and it seems it can be beneficial. I will try to test it with some birds later.

Thank you, Alex!

Regarding "to my eye FF or APS-C without CIZ cropped to the same level as CIZ samples provide less detail than Clear Image Zoomed brick", it would be interesting to run that crop through Topaz Gigapixel (Low Resolution - default parameters), to upscale to the same MP size as the CIS image, then compare the two. The interesting practical question is whether there is some "magic" that Sony does in CIS that is not yet surpassed or equaled by a third-party application. If the same IQ can be achieved in post, this would be the preference of any RAW shooter. I understand that CIS is a useful option for JPG shooters.

I have another sort of ‘question’:

Whether CIS image can be run trough DeNoise or Sharpen and still retain natural enough look if compared to the same image which has been processed in DeNoise or Sharpen without CIZ.

Respectively, to my inderstanding for an image which has been run through ‘2’ instances of AI soft it is a bit difficult to retain ‘natural’ properties.

I can, in theory, test it all but haven’t had enough time …yet.

A very quick and ‘not scientific’ test by any means. Just for fun.

The pictures were all taken with R4 + TC1.4x. One picture ( ) was just APS-C mode and cropped further in LR, another APS-C + CIZ. No other adjustments were done in the LR.

I cannot upload here, so I used DPReview and also zoomed further and took screenshots on my iPad. Download them all in original size and then see details if you want. Filenames and info from LR shows what version it is and what was done to it.

https://www.dpreview.com/galleries/6857394362/albums/ciz (I am not sure if only registered members can acces the files or everyone).

I used Gigapixel (2 modes) to upscale cropped APS-C back to the same exact original px - 6240x4160. (approx. 2x). I also used Sharpen or DeNoise for the CIZ version as I normally use this software on my images.

To my understanding:

1) Upscaled versions in Gigapixel = similar or a bit better than the original CIZ;

2) However, CIZ + DeNoise or Sharpen = similar or better than the upscaled versions in Gigapixel;

3) You cannot derive any definite conclusions as I do not know how it would behave for a different scenes (Birds, for example), and there are many modes and setting % in AI soft removing blur, sharpeing, etc.

As I normally apply one instance of DeNoise to my images in any case, I believe CIZ would still be beneficial as running Gigapixel and removing noise afterwards or before in another AI could, in theory, make more troubles and also take more time besides any other factors. For a simple scene like a brick wall upscaling might be pretty simple for Gigapixel. It might possibly struggle with ‘live nature’ more. On the other hand - all this AI software does impressive things in any case.
