 Topic: A99II display and expousere problemPosted: 26 March 2022 at 21:43 |

Hi! I've just got A99II. I had the first A99, but I've sold it yesterday. Today was my first exstensive shoot with the A99II. Portraits at noon. I had problem with the displays and the exposure. Showing exposure settings is turned on and its correct most of the time. But when I had a high contrast scene which I tried to underexpose (not sure how many stops, may be 4) the displays still showed me a lot of highlights, so I continued to underexpose and when i checked the galery, the photos were black. I tested it with overexposing in another scene and its the same (this time its showing shadows and the photos are white ofc). I tried turning on and of different settings and its the same. A colleague who had A99m2 said he didn't recall having that problem. Also I with my old A99 do not recall ever having it. My questions are: Are anyone else getting this problem? Is there a solution?

Guess you were shooting in either Aperture or Shutter speed mode and adjusted exposure using exposure compensation?
If so it's a known issue with the SLT cameras, they can do +-5ev but not all of the range will show in the viewfinder or on the histogram. I first ran into it using an A77 (will only show +-2ev in the viewfinder) but it's there on the A99ii aswell (will show +-3ev). Anything beyond that won't show a change in brightness in the viewfinder but the shot will come out at your set compensation, hence the near black result. Here's an old thread where I asked how the A99ii behaves. A99ii exposure compensation |

I'm shooting manual but I see the point. Thanks!
Did anyone try to repair this? Edited by darkymir - 27 March 2022 at 00:06 |

Interesting, never heard of anyone having this issue in manual!
Was it full manual and changing exposure with shutter speed or aperture or was it Auto ISO and changing with exposure compensation? Might have to break my A99ii out of storage and test to see how it behaves. |

Unlikely to be the Exposure compensation "issue" then.
Possibly an EFCS issue but I've never seen it (can't say I ever tested it either) on my A99ii but saw it lots while using an A77. Boils down to the faster shutter speed you use the more it will start under exposing compared to what the viewfinder is showing. Used to catch me out while birding shooting aperture mode and fixed ISO, no issue with dark birds as it kept the shutter speed in a "normal" range but shooting bright white birds had the speed go up to say 1/4000sec and it would start under exposing. Fixed by going to a full mechanical shutter. |

I think you have to test this more. Do you have the problem still? Or was it a fluke? Did you try different lenses? Are you sure you put the camera into "Live View Display: Setting Effect ON"?
I never had a problem like this with the A99m2, but I usually use A-mode. |

Live View Display: Setting Effect ON - yes, it's on. As I said, I can see the exposure changing to around +/- 4 or 5 EV, then it still shows some highlights or shadows depending on over or underexpose I try to do.
I also tried different lenses, batteries, metering modes, display quality, EFCS on/off. It's the same using A, S and M |

Just tried the live view modes of my old a580. The same story. So not only in SLTs. It's an old Sony story, I guess.

This probably depends on the lighting conditions in combination with the camera settings. With my A77 in manual mode the rear screen shoes a fairly close to accurate preview from -7 to +7 stops. This is with the camera indoors pointing at a window with partially closed blinds and using 1/60s, f/2.8 and ISO 200 as the 0 exposure level, and adjusting the shutter speed from 1/8000s to 2 seconds. |

You need to provide more information.
We are only guessing at what you are actually doing. Do you have a manual for this camera? You should reset everything to the factory default settings. Then take pictures in the AUTO setting -- NOT M, A, S, or P. Does that work OK? |

Manual is the only mode where you can set the camera to underexpose more than the EV adjustment feature. This issue can never arise in any auto mode.

Yeah, as I understand it, it is not the exposure that is off, but the way the screens show the settings.
Also, the manual is easy to find online. Resetting the camera to factory settings is decent advice as you do not know if there is a setting you cannot find that is set that influences the screen. |

I've just seen the jpegs from the underexposed shots. There are some highlights. I guess what is shown at the displays is kind of correct. And after seeing the same result on the old dslr a580, I think it's just a weird choice from Sony engineers. I'll just have to live with it.
