I've spent the day searching the internet trying to find out how to set my shutter speed greater than 30 seconds. I have seen in a review of the alpha that they tested it at 10 minutes. I just can't figure out how to set it. I have looked in the manual and scoured online. Does anyone here know how to do this?
Thanks in advance. |

The owners manual on pg 43 tells you how to get to the bulb setting,

I'm just having a hard time believing that the only way to go past 30 seconds is to keep your finger on the button. That just seems sooo... well... just not right. Is that a common feature in most cameras?

Unfortunately, yes. My E3 has a 60sec maximum in normal mode. When in B (bulb) mode I can set the duration of the exposure in the camera settings anywhere from 1 minute to 30 minutes but I need my remote to open the shutter. Maybe you have a similar setting in yours?
Or you can buy a wired shutter release which has an option to keep the (shutter) button depressed for as long as you wish.

That's normal in nearly all cameras, that longest shutter speed is 30 secs. Anything more than that, you need Bulb and a remote. My inexpensive remote for the Canon plugs in and has a lock that will lock the shutter open in Bulb.
Incidentally, it's called "bulb" because back in the early days the shutter release was pneumatic, based on air pressure. The photographer squeezed a bulb, and as long as he kept it squeezed the shutter stayed open. There were no mechanical, timed shutters in the beginning; nor electronic ones, for that matter.

Thanks for the history lesson!!! I am forever amazed how the terminology lingers in photography (dash and burn are other examples of this).
All that being said, I just don't understand why the camera makers universally decided that holding your finger on a button would be a good thing. There was one picture on here where the photographer did star trails over a tulip field (it was amazing). In his description I believe he said that it was a 4 hour exposure. How crazy is holding a button for 4 hours????????? I could think of better things to do instead (like curling up in a sleaping bag for example).

They didn't. Read my post above. :) They never intended for you to use the shutter button in Bulb mode. |

Here's a link to B&H for a wired sony alpha remote with a shutter lock...

Just got in here, not sure if you sorted this out.
According to the alpha 700 manual(p 44), (a link to this maual is posted in The_Tourist's reply above, I am new and was not allowed to post URLs :-)
You can shoot in bulb exposure mode up to about four and a half hours using a fully charged battery pack.
After shooting, the noise reduction will be done for the same amount of time that the shutter was open...
The Sony alpha 700 comes with a wireless remote control, setting the exposure to BULB mode and the drive mode to Remote, you can press the Shutter button on the remote (the remote must be pointing to the front of the camera) to have the shutter opened. The shutter will remain open until you press the Shutter button or the 2 SEC button afterwards on the remote.
Alternatively, you can press on the 2 SEC button of the remote to allow the mirror lock-up before opening the shutter, reducing camera shake caused by the movement of the mirror. Again pressing the Shutter button or the 2 SEC button afterwards on the remote after that causes the shutter to close.
I tried it on my Sony alpha 700 and it worked. I hope this is gonna be helpful.
