I have heard a lot of quibbling about mirror lockup being a timer element only on this list as well as others over time. I agree that the real thing would be better and I'm not exactly quite sure why they don't do that as I don't see why it's so hard to do. However in reality when I consider this, I don't feel that mirror lockup is of any use to begin with unless your on a tripod and using a release since hand holding or even touching the camera would probably cause more movement then the internal mirror function. After I go through all this I am most likely setting up for a still shot that isn't moving or moment critical to begin with. In a studio the shot is often shot with a soft lens to begin with and at close range so again the mirror lockup doesn't seem critical. The only situation that comes to mind is if you were set up for wildlife at long range and trying to catch a moment there.
My point after beating around the bush all day is in reality, how many times does the absence of true mirror lockup vs. timed mirror lock really hinder your chances of getting the shot correctly. I don't mean hypothetically, but rather real time experiences that you have actually encountered and either regretted not having it or really did need the true mirror lock feature. Personally I love the 2 second timer feature as it means not having to dig out or carry the release and I'm probably more likely to actually use it because of the same reason. Not arguing that the true thing isn't better, just really curious. So educate me here ok... :).
