Hi Guys, new to the forum but have been reading from the wings for some time now,
Looking for some help or advice regarding my sony hdv-z7e,
Basicaly i have my shutter locked down to 50 and white balance set and also locked down but auto iris but even in a dull room my apature goes all the way down to f11 and still asks for nd1- nd2, just seems that when its in auto iris is always at the high end , outside in the sun its f11 and nd4, is this normal for this camera? my z1 would happily sit at f5 in bright conditions,
Any help or advice appreciated,
Thanks

You don't mention where the gain is set, which is another thing that can affect exposure.
-
Hi, Sorry the gain is set at 0 but have tried -6 and that helps me open the iris a little more
-
Definitely sounds like something is off. If you go full auto does the picture look properly exposed?"
-
In auto the picture is not what i would expect from the z7 (my z1 seems better)
-
Try the reset button. Go to a "normal" picture profile and reset that. Make sure hyper gain is off. Double check the lens mounting. If none of this works it may be a repair-shop level problem.

Hi, reset normal picture profile and just seems the same, for all i know this could be normal, I have attached 2 pictures and on both its set at nd2 and calling for nd3, the light comming in is not direct sunlight but is bright, do you think the appature numbers looks right for the conditions? Thanks

It doesn't look unreasonable -- but an actual captured frame, or short clip, would be more helpful. Point it at something other than a light source -- even better a test chart.

My biggest worry is I will be filming abroad in the next few weeks and worried i will have to have the iris almost closed (f11) all the time in the daytime sun,
If this is normal then i can live with it but its the not knowing thats bugging me, -
Aside from normal YouTube artifacts, nothing looks noticeably off for an auto iris shot. 1/50th is the slowest shutter speed you can use, so the iris will be open the most. If you're looking for a lower f. stop, (short depth of field?) raise the shutter speed, lower the gain and add ND's. (You can add filters to the front of the lens if you need to.)
