Just a simple question?

Hi all

If camera manufacturers caused the camera shutter to close when the lens release button was pushed! (OK It could be disabled for sensor cleaning :) ) wouldn't this help reduce the problem of getting dust on the sensor :thinking:

The shutter is shut when you take the lens off! The mirror is down too... what happens though, is that some dust will enter the compartment, then be blown/pulled onto the sensor by the violent movements of the mirror and shutter.

OK, many thanks :) I thought the idea seemed too simple to be good .... :bonk:
 
How long before images will be captured by some form of inbuilt optical gizmo or such like? :shrug: The shutter equivalent will be controlled by an elecrtical pulse that switches of the light passing through, all contained in a sealed unit. Hey! Presto!! no more bunnies. Just remember where you read it first :D

You mean like a compact camera? :thinking:
 
I've often thought that with todays technology that dslr's are needlessly complicated. Why have a mirror at all when the image can be dispayed on a digital display from the sensor with all the focussing handled in auto.
 
What you need is a button, when the lens is attached, the camera will suck out the air from inside the compartment creating a SEALED vacuum. And re-pressurize when you change lenses.

Prob too extreme thoug :p
 
kick me if i'm being stupid but surely a fix could be the inclusion of a consumer changeable disposable charged surface designed to attract the dust, thus at least reducing the chances of it getting onto the sensor? In effect a dust magnet with more "pulling power" than the sensor...

Or is that too simple a solution?

I use a miniture mains driven sucker myself, much better than blowing dust around the area.

Because lcd viewfinders are in my opinion nowhere near as good as an optical one. I'd pick optical any day. If that's your thing though, check out micro-four-thirds format cameras.

Or a lot of the bridge camera's, most of them have viewfinders with lcd screens in them and they are awful compared to a proper optical viewfinder.

Thats just my opinion though.

:lol: I was thinking more on the internal workings, still have a dslr with interchangeable lenses, but lets face it any part inside a camera that moves ie: mirror is old hat by todays standards. Now if the image seen through the lens was captured within the lens and then transmitted to the sensor within the camera via contacts, you would in theory have no need for a gaping big hole the size of the Channel tunnel on the camera body. When you take a look at the first plate camera it was a case of pull out the cover slide, count and place slide back. It all equates to light hitting the storage device.

Too simple Heppy, remember it has to be something so that the likes of you and I wont understand how it all works :D I think my idea is far more sophisticated :thinking: Suppose I could just a get a T mount for my Henry :thinking:
