vertical strips on sony ar7ii (some pictures)

Recently, I bought a Sony AR7ii and did about 2k photos with it.
works fine, but sometimes I see these black stripes.

I have no idea what causes it and how to avoid it. any idea would be appreciated! (

mirror – sony xz premium Mirroring the screen with a pc – HDCP error

i am trying to connect my sony xz premium with my pc, it 's connected first without error, but when i open an application, it gives me this error

Mirroring error
Your output device does not support HDCP.
Can not reflect. You can still mirror some apps and unprotected content
to the device.

I see corrections to edit -> wfdconfig.xml by changing the value ContentProtection -> Valid from 1 at 0
This solution applies to rooted devices but I need a solution without rooting my device.

sony – DRO, Photo Profile and Auto Mode – Why can not these settings coexist?

I am a novice in professional photography and I am still trying to understand some crucial things. I really hope you can help me.

I have a Sony A6500, I'm trying to switch from Auto to Manual settings, I'm testing image profiles and I'm discovering the DRO, but there are two things I can not understand.

1) Why can not I use the image profiles in automatic mode?

2) Why can not I use DRO when image profiles?

I've searched a lot for this, I found quite useful information on why PP does not affect RAW files, including:

"In automatic mode, the image profile is locked in. It is always there and applied to show you the preview."

If there is an image profile in automatic mode, why can not I change it or change the values?

These questions may be obvious to most of you, but that makes no sense to me.

Color Management – Sigma for Sony can be calibrated with Sigma Docker. What about Sony lenses?

So, I am so confused on this subject because I can not find any information anywhere. Sigma introduced 3 years ago a great tool, Sigma Docker, which allows, without any special equipment or extraordinary skills, to recalibrate to focus the objectives Sigma & # 39; nose & # 39; instead of "eye", we can already see it).
But Sigma lenses are much heavier than Sony's lenses. A 100mm E-mount Sony lens is probably two times lighter than Sigma's 105mm F1.4 lens, which even boasts the "fitting socket" for bodybuilder tripod.
How is the Sony 100mm E-mount Lens Callibrated? Is it always the case that we have to send it to "service" and have a laboratory, draw lines on paper, and so on? and make the settings with scredriver?

lens – Display of rattling and flickering when using Sony 70-200 F4

The "click" you hear is almost certainly the OSS (Optical SteadyShot) mechanism of the lens. The lenses of almost all manufacturers that include lens-based optical stabilization emit similar noise when starting or when compensating for camera / lens movement.

Your 24-105 and 28-70 lenses are not equipped with OSS because the IBIS system built into many Sony cameras is sufficient for these focal length ranges. However, at longer focal lengths, the same camera movement causes the subject to move more as a percentage of the frame size. The range of motion of IBIS is limited by the size of the image circle projected by the lens as well as size and space constraints inside the camera body. Thus, Sony has added the OSS to the telephoto Sony FE 70-200mm f / 4G OSS, longer, to complete IBIS.

Focal length Sony RX10 iv

I have a Sony Rx 10 iv. I've used the maximum zoom, 600 mm, but when editing in Lightroom in the details, the focal length is 220 mm.

Can any one explain, please?

Sony Cyber-shot DSC RX100 – photo without memory card

Using a Sony Cyber-shot DSC RX100, I went to shoot, but later realized that the SD card was not in the camera.

I suppose there must be an internal memory in which the photos are stored, but I can not figure out how to access it to retrieve the photos.

Is there a way to recover the photos?

Digital – Sony Mirrorless A6000 – A Mentor asks to set the image to Fine rather than RAW

Until now, I've heard about one reason why the camera was recording RAW format images instead of nothing else. The JPEG format is a form of image data loss and so I always thought that it was wise to save the image data as is (RAW).
Recently, I've heard an argument that "Good" is a better format for saving your photos because you do not have to reproduce the algorithms executed by the camera to display your photo on the small screen of the device.

What is the difference between JPG and a good balance between RAW and JPG?

How to live live on a laptop to show what's on the screen of a Sony HX60 camera?

To solve this problem, there are several ways to do it. The first and probably the easiest way is to use a USB capture card like this, then save it to a computer with software, but I do not know if it also shows the camera's HUD (and if you wish it). This method has the advantage of being able to use your camera normally, as you would without the cable.

Another way is to use software that detects your camera as a webcam. An example of this can be found here. This method poses only the problem that the camera is in PC mode and that your use on the camera side is limited to the control exerted by a software on the PC.

The HDMI and VGA ports of your laptop are just the output of your graphics card.

Another option to achieve this is to show and explain in this YouTube video

Sony F5121: Forgotten Device Password, Bootloader Locked

I have forgotten the device encryption password for my F5121 (boot loader locked). Is there a way to reset the device so that I can use it again (the data it contains does not bother me)?

I've already tried a combination with the Volumne + Up / Down power button, but I do not see any options appear.

In addition, unlocking the boot loader does not seem to work (I would have probably had to activate the OEM unlock in the Android settings before), it says:

FAILED (remote: "Unauthorized command")

Same mistake when trying to flash TWRP.
