| On cameras Part 1:

Here's the start of a series of commentaries on cameras. Feel free to pick out mistakes, but I've made sure I've researched everything.
Continuing on the topic that Vu has raised...viewfinders on DSLRs...
a.The 20Da The 20Da's supposed live view function is nothing of note to anyone who wishes to use the camera normally. That's why everyone buys the 20D instead. The point of the live view function is specially made for astrophotography. Since our eyes can't see infrared, the live view will allow the sensor to cature the infrared and display it onscreen so you know what you are taking a picture of. The sensor can capture infrared but the eye cannot. Also, since the 20Da is not built with the technology Sony has incorporated into the R1, it's likely that the view is not "live" but a series of captures displayed in slideshow fashion. It's definitely not live, though, in the digicam sense. Some have mentioned that it may be able to do infrared photos, but Canon has stated that there is actually an infrared filter, it merely blocks out near infrared, which is the kind that people are interested in. However, that would mean it could be used normally. But, sicne the 20Da doesn't ahve an electronic shutter similar to the one in the D70, it's not likely that it can be used in daylight.
b. The Fuji S3 Pro The Fuji S3 Pro also has an interesting live view function. It's black and white, lasts for 30 seconds, and has magnification. The black and white is probably because the camera has not interpolated the image into colour as yet. There's no reason why not, since digicams always do this, but since the other features of the function are lacking, it's not a huge problem. Some have said that this makes it suitable for a studio camera, however the real feature that is lacking would be mirror lockup. Granted, Nikon did not incorporate mirror lockup on the F100, reserving it for the F5, thus the F80 wouldn't be allowed it at all. But of course the D200 rumours are that both self timer and two stage mirror lockup are possible, no doubt bowing in to consumer pressure and cheaper cameras overall. It's curious as to why you cannot take a picture while in live view, as that would solve mirror lockup problems, but suffice to say, the live view function of the Fuji S3 is not very useful. Checking focus with the angle finder would be just as good. Can it help for that low angle shot, probably, but a cumbersome interpretation. Live view could be useful on DSLRs, but for most times, the viewfinder is superior. We'll see with new technology, however. |
