It doesn't. Here's the same file processed identically in ACR/PS, one with lens corrections and the other without. Full-sized images: Image: Z7 banding sample, with lens corrections Image: Z7 ...

It definitely does not occur for uncompressed, and Sony currently doesn't offer a lossless or alternate lossy compression algorithm. Btw here's going way back on this: https://www.dpreview.com/foru ...

You mean in general shooting? It's pretty common on high-contrast edges of exposure pushes like the lettering in that DR crop.

That's the result of their raw compression algorithm. They don't appear in their uncompressed raws.

Haven't seen this channel before. Really like his style and delivery. Good review content as well. Thanks for sharing.

There are a few layers to this. At the bottom is the camera, which has firmware support for MTP , a mechanism that allows control of the camera's functionality over USB and WiFi. MTP is an industry ...

Not at all, just posting in case others want to develop their Z7 raws in ACR/LR w/o corrections, rather than having to resort to using other raw processors that don't honor/force the use of the ...

Jim, I posted comparisons previously as well, including instructions on how to defeat the built-in ACR/LR corrections: https://www.dpreview.com/forums/post/61869525

Thanks for supplying the raw. Only the second file/raw seemed to be available for download (_DSC1306.NEF). I'm able to see the banding but only after some very extreme contrast adjustment, which ...

Roger, I can write you a script that will automatically determine the number of steps for a lens (using the gphoto2 app). Then you can hook up various lenses to the system to build that table. ...

Hmm, the only BIOS setting you should need to worry about with running Linux in a VM is making sure the Virtualization features of your processor are enabled, and most are those settings are more ...

It's more an observation. By allowing the camera to focus for 2 seconds, it will potentially focus more in AF-C mode than AF-S within the same allotted time, since the former focuses continuously ...

The camera may use that time to continuously focus in AF-C whereas it may only focus once in AF-S.

For AF-C the camera may permit itself more time to focus, depending on how long AF-ON/shutter is engaged prior to the exposure. Maybe check how the camera responds to triggering from the external ...

Thanks for the recalcs Jim. I think it's important how the wide AF-S has a much lower stedev than the normal AF-S. I observed the same thing on the Sony MILCs. I believe this is due to the ...

I placed three pieces of tape on the MF ring of my 50G, one at MFD, one at infinity, and one half-way in-between. I then determined the programmatic step distance to focus from infinity to MFD is ...

I'm guessing it's non-linear, at least in terms of focus space/distance, based on an article I once read from Roger Cicala. But I don't think that is material for my test since I'm commanding the ...

Things get more interesting when I tested the 50G f/1.8. Here are the results on the Z7+FTZ, this time with 10 photos instead of 25. Click "original size" to animate: Animation of 10 photos, Z7 + ...

LR is relatively slow even on very fast systems, particularly its demosaicing. It doesn't take much advantage of multi-cores/parallelism except for specific operations like imports and exports. ...

Where's the tangent in this thread? Without a Z6 in hand others attempted to predict/answer your question using technical knowledge of existing sensors.
