Can you do mirror lock up and use the remote on the A900?

Unfortunately not as the mirror lock up function is coupled with the 2sec self timer. Technically speaking yes which means you can set off the 2 sec self-timer with the remote control but you can't really influence precisely when the shutter will trigger.

The mirror lock up is only available with the release cable and not with the remote control even if you are in the 2 sec self timer(with the remote control) correct me if i am wrong

TG- sorry mea culpa you are absolutely correct. I was talking about the release cable and not the remote control. It is a serious oversight from Sony IMHO. I think they should have a separate mirror lock up function which is not related to the 2 sec self-timer. :(

Sony screwed that up.  The IR release should simply act as a shutter de-press and otherwise follow the drive mode as it is set.

I do not have one so could be wrong, but doesn't the A900 (and probably the A850 too) have 2 MLU modes - one that is linked to the 2 second timer, and a separate one that works more conventionally with 2 button presses - one to lock the mirror, one to expose?

It does but the MLU as well as the 2 second and remote are all selections under the drive mode and you can only choose one of these at a time.

From Firedman Archieves

“Happy now?”, cried the engineers, annoyed that the general public had not acknowledged their tackling of the problem in the first place.  “No!” cried the experts (who in hindsight were probably the same people who insisted that Pro cameras don’t have popup flashes).   "You can't use MLU in "B" (Bulb) mode when you're taking pictures longer than 30 seconds!"

 

This standoff lasted for about 2 decades. And now, out of the blue, without warning or explanation, Sony has very quietly added a mirror-lock-up function to the A900, in addition to the 2-second mirror pre-fire on the self-timer.  When this mode is invoked, you have to press the shutter release button (either on the camera or via a remote cable) twice to take one picture:

•The first time you press the button, the camera autofocuses, and takes note of the exposure, and flips the mirror up.

•The second time you press the button, the camera takes the picture.

Notice that you have up to 30 seconds to press the button again – after that, the mirror drops down without taking a picture. This is a power-saving feature, for the mirror mechanism uses electromagnets which consume batteries to keep the mirror up.

 

Is this new feature better than the 2-second mirror-pre-flip of the self-timer?   If you use Bulb mode a lot (as do astrophotographers), the answer is "yes".  For any other shutter speed of 30 seconds or less, the 2-second self-timer is an easier choice to work with.

 

"Hey, at least the press will be happy!" says the Sony Marketing guy.  (And they would have been, too, had everyone not been distracted with why the .jpg algorithms from the A700 firmware version 4 didn't make it into the A900...)

I have closed this topic and removed a number of un-called for posts.

While the initial question has been fully addressed, feel free to open a new discussion about the equipment.

However, play nicely or don't pay at all. Personal abuse etc won't be tolerated.
