The end of 35mm adapers and hv20s....

Exposure Lock

Exposure Lock

Seems like it would not be that difficult to come up with a mechanical attachment with a lever you flip that locks the button down in the position it needs to be in. Could do that until someone comes up with a firmware fix, (if that's possible).
 
If the button is the key any solution would be good, but until we see were the button is positioned, etc. we won't know what to do for sure. I know Nikon would have to solve that problen if there is a problem.
 
I just noticed it in my 40X and tried it. I never cared about that button really because I always use manual mode. Its no big deal, you just press it with your thumb, but something can be worked out to hold it down by itself. I supposed that even people using it during the tests that we saw might have pressed it but because lack of practice may have let it go for a little while without even realizing it. We will see.
 
So that light won't matter if it's covered up. And yeah, it'll be a breeze to clamp the button down, but I still think the exosure can be set and locked without having to push that button down. A few pages back Hunter posted a function in the menu showing "exposure lock-m" or something along those lines.
 
Ok I just tried it again on my 40X. The AE-L and AF-L button, which is located in the same place as the D90 in the picture, locks both exposure and autofocus when the camera is in the A (auto) Mode and you leave it pressed. Then I moved the camera and could override the focusing manually. It should work the same way in the D90.

Exactly, the menu has a Hold and Lock option. The Hold is for the photographer to quickly keep reseting his exposure when he centers on different brightness spots within the frame. Whereas the Lock setting, the photographer can set on a certain zone for a giving sequence of shots in a given environment, and not deviate cause it's locked. It's like having a reseting light meter when in hold mode.

Now that said, even if you ever had to clamp a button; so what! It's easy to do, and filmmakers/Cinematographer are notorious for DIY-ing issues to make all sorts of things work for their needs. Filmmaking is largely problem solving not problem bitching.

The Nikon D90 is a first step in a revolution to a new future of acquisition. Nothing to worry about on this subject anymore. Whatever problems come up, there will be a dozen great ideas to overcome it.

We are assuming the shift in exposure is part of the exposure, and therefore can be locked. Have we determined what is exactly shifting?

Not to be the negative nancy, but could it be the matrix metering? Something that cannot be disabled?

Just saying. Sorry if it's a rain cloud thought.
 
Yes, you would think they would. They won't necessarily say it will overheat but rather would put a positive spin on the problem like, "Record up to 5min a clip!"


Good point.

More footage supposedly taken with the D90 on http://www.youtube.com/watch?v=M5DD0QaMUKA . Unfortunately in incredible bad compression quality. I´d love to see this one in HD.

Bike footage is amazing. The use of wide angle lenses like that without the adapter BS compromise is great. Even in that low rez it's quite apparent that the 12.3 MP density and excellent dynamic range makes for good images. Awesome how the D90 was mounted on the bike. I wish we could get this in HD.
 
Probably safe to assume that all the footage we've seen so far has the kit lens on it.

That could be the result of certain soft images that people are seeing, because Kit Lenses aren't exactly "great" glass. LoL

mmmm Sunday can't roll around quick enough.

Here are some clips I found of somebody testing the D90 in some display area somewhere.

These kinda go along with what I'm saying about the rolling shutter and focal length. In the first video, you can see that when he's at a longer focal length the rolling shutter is a lot more apparent. Even in small moves.

At wider focal lengths, even though he can't hold the camera steady to save his life, you can barely see anything at all.
 
Must make it by far the shortest large sensor HD camera you can buy. Great for those tight applications.

Just imagine where this is going to go
