Hello all,

I have the A73 for quite a while and have been mainly shooting still photo and 1080P video. Just today, I tried to the 4k video and to my surprise, something is wrong with it. There is a vertical red line straight through the frame. 

Seems like some sort of hardware issue? Anyone has similar issue? Need some help!

Is that a pic of the screen or actual video? A continuous line top to bottom is a problem with that particular circuit either on the monitor or sensor.

(Had to exchange mine because it developed a group of purple pixels only in 4K 3 weeks after purchase.)

Windows Screen capture on the video playback. I can see the red line on the screen at the back of the camera as well. Does the camera uses a separate chip/processor to do the readout of 4k video? Maybe the hardware for that task has issue. I may have to contact sony on this. The camera has been purchased more than a year ago though. Does anyone has any experience with Sony customer support on this sort of stuff?

But i wonder why it only affect image in 4k.

Resempling algorithms in 4K and HD modes are different. In HD mode, 20 megapixels are taken and converted to 2.1 megapixels. Maybe that's why such a thin strip isn't visible in the frames.

      Centre Focus on A7R3

      By Pieter · Posted

      I'd use Focus Area: (Expand) Flexible Spot: S instead of Center. Smaller focus area and more control over where to focus. https://helpguide.sony.net/ilc/1710/v1/en/contents/TP0001653124.html

      Custom white balance for studio flash.

      By vinniemac · Posted

      New Sony user here, trying to get my head around all of the differences from Fuji 😬  I’ve figured out most of the settings, but can’t find any answers on how to do a custom white balance for studio flash. The custom setting option only seems to be based on measuring ambient light. The only workaround I can think of is to set an approximate kelvin value and then shoot a grey card and fix it in post, but I’d much prefer to get it right in camera.    camera is an A7CR TIA Vinnie

      Sony Alpha 7 III - What type of filter? What do you recomme

      By tadwil · Posted

      I am not sure what effect you are trying to achieve regarding the bluish cast of the water.  Do you want to neutralize it or enhance it?  It would be best if you Google polarizer filter for camera and look at the images and videos and see if you can find the desired effect that seem to mirror your situation.  If you can't find the effect you are looking for, it may not be possible to do so with the Polarizer.  I use the polarizer to minimize the shimmering reflections in the water that would look distracting in the image. Neutral density filters are used to reduce the amount of light coming into the camera.  If you want to shoot a small waterfall and you want to create an angel veil effect by reducing the shutter speed to seconds but the light conditions won't allow you to do so, you can use neutral density filters to shoot at very slow shutter speeds. Neutral density and polarizing filters can get very expensive.  If your lenses share a common filter size, that would be great.  If not, get the filters for the largest filter diameter lens and get a set of stepping rings to use with your smaller filter diameter lenses.
