Beim Verstellen der ISO-Empfindlichkeit o.ä. geht die Hintergrundbeleuchtung des Monitors auch dann an, wenn man währenddessen gerade in den Sucher blickt, obwohl der Eye-Start-Sensor am Okular diese Situation erkennen müßte (normalerweise geht die Beleuchtung aus, sobald der Sensor erkennt, daß jemand in den Sucher blickt). Dies blendet den Benutzer, dessen Augen sich an die Dunkelheit adaptiert haben, und es stört enorm bei dezenten Aufnahmen in der Finsternis, etwa im Theater o.ä. Veranstaltungen.
Die Fehlerbeschreibung gilt für die DSLR-A700 (Ausführungen mit und ohne Griffsensor) mit Firmware 1, 2, 3 und 4. Dieser Fehler bestand schon bei der Konica Minolta Dynax 7D und 5D sowie der Konica Minolta Alpha Sweet D und wurde auch mit den letzten Firmware-Versionen für diese Gehäuse nicht behoben. Auch bei der DSLR-A100 existiert der Fehler mit allen Firmware-Versionen. Das Problem besteht leider selbst noch bei der DSLR-A900 (Firmware-Version 1) und betrifft nicht nur die ISO-Taste, sondern auch +/-, DRIVE und WB ebenso wie alle Menütasten am Display sowie die FN- und C-Tasten und nicht zuletzt auch die Intelligent Preview-Funktion. Offenbar sieht Sony dies als Feature an - aber wenn schon, dann sollte es konfigurierbar sein!

Das folgende Verhalten würde ich nur zum Teil als Fehler betrachten, da es in manchen Situationen auch sehr nützlich sein kann, es wäre aber schön, wenn man das feiner konfigurieren könnte:
Auch bei deaktiviertem Eye-Start wird der Eye-Start-Sensor offenbar weiterhin benutzt, solange die Kamera noch aktiv ist, was in bestimmten Situationen den Eintritt in den Standby-Modus praktisch unmöglich macht.

ZITATThe behavior of the A700 when eyestart is turned off with regards to
sleep mode is strange and, I think, faulty. It causes my battery to
drain much faster than it should. For example, turn eyestart off, set
Info.disp.time to 5 sec, and Power save to 1 min because it will be
easier to see the problems.
The first problem is that the A700 continues to use the eye sensor and
that prevents the camera from going into sleep mode. While carrying
the camera on the neckstrap (around your neck or over your shoulder)
the eye sensor will often sense something close by and will keep the
camera awake. When eyestart is turned off then the eye sensor should
not be used to keep the camera awake. The eye sensor can still be
used to detect that the eye is close and turn off the LCD, but after
the 5 second time has elapsed *even* if something comes near the eye
sensor the 1 minute sleep timer (power save) should not get reset and
start over. This behaviour is okay when eyestart is turned on, but
when eyestart is turned off the camera shouldn’t be ruled by the eye
sensor. Also, even if I hold the camera by the lens very still for 5
seconds to allow the display to go off and start the countdown to go
into sleep mode I have found that outside in sunlight the eye sensor
sometimes seems to be detecting something (maybe just a passing a
shadow) and the LCD will not go off. By the way, if someone wants to
turn off eyestart but keep the LCD on for much longer then they can
select a longer time for Info.disp.time and/or Power save.
The second problem is that even if the LCD goes off and 1 minute later
the camera does go to sleep it is too easy for it to awaken. In order
to awaken the eye sensor must detect something and the grip sensor
needs to be touched. I walk around and carry my camera a lot for
hours at a time (I do foreign travel photography) and because of the
weight I usually have the camera strap around my neck and I am holding
the camera in one hand to reduce the weight on my neck and to keep the
camera from swinging around too much. I cannot hold the camera with
my right hand because it will touch the grip sensor and the camera
will awaken. I am forced to only use my left hand to hold the lens
and it gets very tiresome to not be able to switch hands sometimes.
Also, I have noticed that sometimes just a slight brush of my hand on
the grip sensor while the camera is hanging from my neck will be
enough to awaken it. With eyestart off the A700 should require a
button to be pressed to awaken the camera.
By the way, the A700 designers themselves have set the precedent for
ignoring the eye sensor sometimes. Another bug is that if I hold the
camera to my eye and then change the ISO the LCD strangely lights up.
I am looking through the viewfinder and ISO is displayed in the
viewfinder. There is no reason to light up the LCD. That is a big
nuisance in a dark theater or other place to have the LCD light up for
no reason. The eye sensor is ignored which is strange.
I have owned and used several DSLRs from Canon, KM, and Sony. My
Canon 30D did not have an eye sensor and it required a button press to
awaken the camera (I usually just did a half-press of the shutter
button) and it would go to sleep after the time out without any weird
shenanigans like in the A700. I think that when eyestart is off the
A700 should behave the same way. There have been threads about this
subject on some of the digital camera discussion forums also.[/quote]
ZITATI’d like to second Henry’s comment about the eye sensor trigger to prevent the
camera to go to sleep mode. The sleep count down should only be interrupted
with the press of a button. Furthermore the camera should awake from sleep
mode also only with a press of a button.
At least selecting this behavior should be an option in the menus.
And the highlighting of the LCD while holding the camera to your eye is an old misbehavior dating back to the time of the KM DSLRs, that should be fixed in a
future update.[/quote]
