LCD use

[santiverdu]

Hello everybody.

I'm very happy with my S2 Pro, but I'm asking for the possibility to use the LCD screen 'to fit' the photos, not only to review them.

Do you know if there is any possibility?

Can you explain what you mean by "fit" the photo's? Are you meaning cropping the images in-camera?

Hi Santi,
if I have understood well your demands, test this site:

Santi,

If you mean to compose your image on the LCD, as you commonly can with rangefinder style digital cameras - you can not.

In order for the LCD to display a live image, the sensor must be able to see a continous live image through the lens. In the Fuji S2 and other DSLRs, the mirror and shutter keep the sensor "in the dark" until the moment of exposure. The only time the sensor is exposed to light is during exposure or during cleaning.

On a rangefinder camera, the ability to compose the live image on the LCD is a benefit, and often required because the image you see through the viewfinder is not the image that the sensor will see. Rangefinder cameras have separate lenses for exposure and viewing. The live image on the LCD shows the image as the sensor sees it - through the lens that does the exposing.

On an SLR, the ability to compose through the viewfinder is a benefit because you see exactly what the sensor will see - because your eye and the sensor recieve their light through the same lens, just not at the same time. While you are looking through the viewfinder, the path of light is reflected onto the focusing screen. During the exposure, the mirror flips up, the shutter opens/closes allowing the sensor to be exposed. The image on the sensor is recorded digitally, and optionally, displayed on the camera LCD.

There is no current way for the sensor to accept a continous image at the same time the mirror is reflecting the light through the viewfinder. My unverified source says that the Quadcon 20-20 has multiple lenses and can provide a live LCD image, and shoot with other lenses attached to the multiple lens 4SLR. See the post at http://www.s2pro.com/forums/showthread.php?s=&threadid=621 that shows the Apple version of this amazing camera.;)

Yes, that was my idea. The possibility to use the LCD screen as a viewfinder in some situations.

Of course I agree that is better to use the viewfinder all time, because it's more 'realistic' but as you know in some complicate situations it would be interesting to use the LCD only to get an idea of 'how will be' the shoot.

My 2 year old E-10, a SLR, can give me live preview on the LCD.

I did not know that. I have much to learn.

How can the light go through the lens and be directed to both the sensor and the viewfinder at the same time? Does it have an electronic or optical viewfinder?

The Olympus 2500 SLR allow the LCD to be used as a viewfinder also. These cameras use a prism to send half of the light to the optical viewfinder and half to the imaging sensor.
