A7IV - exposure readings in camera

I've just spent 3 weeks in Europe having only shot my new A7IV around home to get accustomed to it after having a A77II for many years. I shot almost 2K images on our trip. Exposure was challenging going from white buildings in and out of shade to darker narrow streets. I was constantly adjusting the rear wheel to see images that were bright enough. I could not lock the rear wheel in any reliable spot, and I could not look at the arrow at the bottom of the screen (finder or rear screen) and settle on a constant exposure to use.

As I was beginning to see I had this challenge to keep images from being overall too dark or light and having to make these adjustments I noticed the arrow location that shows where the value of the over or under exposure adjustment is at as the rear dial is turned was actually one large arrow and 4 smaller arrows. (Not just one simple large arrow.) I was shooting in program mode trying to get the camera to do its best and making adjustments on top of that, rather than shooting in A mode like I used to do the most of with the A77II. Most of my shots were buildings and nice sharp images were my main concern. So I used F5.6 as a set aperture to lean a bit towards brighter images and that seemed to be sharp enough. To confound the large and 4 small arrows, the adjustment at the bottom of the rear screen seemed to show an average of all the 5 arrows with only one value (like .3, .7, 1.3 as I set the camera on thirds for that setting.)

I am looking to find out what the large and 4 small arrows are and are doing. For a short time I set the camera in Auto just to see how some shots would come out. It did fairly well, but still needed to make adjustments though a little less often. But I want to keep learning to use the camera in A and P mode.

There were times I would put the finder to my eye or look at the rear screen and see it was totally blown out or totally black with a few colored lines as if the lens cap was still on. The only way I was able to get out of this and see an image clearly was to turn the camera off and back on.

I was able to get pretty good exposures, though I often took 2 or 3 and then decided on a keeper. I don't wish to keep doing that. Since it is likely the camera is doing what it is supposed to it is probably up to me to understand better what it is doing.

Can someone straighten me out on using exposure adjustments and why so many arrows are showing the value of the adjustment? Thank you.

Also could someone help me find the setting where I can reset the time the cameras uses to turn itself off after so many seconds or minutes to staying on.

Thanks again,
 
First of all, I don't understand why you wouldn't just use "A" mode (aperture priority) and set your ISO at something reasonable?

Optionally, you could set your camera to "M" mode, set your aperture AND your desired shutter speed and allow the camera to use AUTO-ISO.

Despite having an a7R3 (I know, not what you have) I have NEVER seen any arrows in my evf or on the rear screen.
 
havnt got my a7iv with me atm but can tell you its a very complex beast until you set it up for your type of use, i would recommend watching a few utubes to get you started. i dont have any of the issues you describe and the camera nails the AF and exposure at near 100% of the time for me. i mostly use A and float iso with a min shutter speed set for 1/250 for my event shoots. have fun and dont rush the learning curve its a great camera.

As Massinissa guessed, the multiple arrows indicate that a bracketing mode is active. Since you were constantly changing exposure compensation, I'm going to guess this specific mode:
  • Exposure Bracket, Single, 5-shot, with an unknown exposure increment
This mode can be accessed by the Fn button or the Drive mode button on the left side of the rear control wheel. This Drive mode has been around since the SLT days, so your A77 II had it too.

Exposure Bracket, Single takes one shot with each press of the shutter button, but with adjustments to the EV increment. The multiple arrows indicate the adjustment for each shot. For example, Exposure Bracket, Single, 0.7 EV, 5 shot will make adjustments with each press of the shutter button:
  • 1st shutter press: normal exposure
  • 2nd shutter press: -0.7 EV
  • 3rd shutter press: +0.7 EV
  • 4th shutter press: -1.4 EV
  • 5th shutter press: +1.4 EV (sequence ends)
The sequence then repeats with the sixth shutter press, returning to normal exposure. Without changing the Drive mode or turning the camera off, I'm not sure if there's a way to cancel or reset this sequence once it starts.

Exposure Bracket, Continuous, shoots the entire sequence with one long press of the shutter button. The sequence can be cancelled by releasing the shutter button. I use this mode quite often for HDR landscape photography.

This may explain why you were having so much trouble. You were fighting against what the camera was programmed to do.

This all makes sense now per your explanation. A check of the camera settings, and yes, somehow I activated single bracket mode in the drive mode menu. In my haste in the moment I must have selected single bracket, and not single shooting.

Thanks you very much for your help.
 
Think I will shoot with 'A' for a while and set minimum shutter for 1/125. And see how it goes. Most of my shooting is landscape and travel. 1/125 should be fine as I usually have a 20-70mm F4 on the camera. I can always change to 1/250 if I put on a 70-200mm F4. If I want more bokeh in a special shot like a waterfall or something I can change it as well.

Gotta' work out a routine for myself that encompasses my shooting.

Thanks for taking the time to reply.
 
Yep ...bracketing ...you guessed it.

That ought to simplify your experience while giving you great shots!

I may totally mis-understand what you meant by what you posted on your reason to choose f 5.6. so pardon me in case: Image brightness is a result of overall exposure determined by shutter speed, aperture and ISO. Choosing an aperture is mainly driven for choosing a DOF adequate for the subject matter.
Also could someone help me find the setting where I can reset the time the cameras uses to turn itself off after so many seconds or minutes to staying on.
To adjust the power save settings on a Sony a7 IV, navigate to the Setup menu (the briefcase icon), then select "Power Setting Option" and then "Pwr Save Start Time". You can choose a time interval (from 10 seconds to 30 minutes) for the camera to automatically enter power save mode when idle.
Thanks again,
If it helps?
Cheers,
Ralf

Yep, sorry for any confusion on my choice of words. Thanks for the PWR save tip.
