My camera I have a canon DSLR which has two reflex mirors attached to each other. When taking a picture, the larger one moves in but the smaller one doesn't. This then takes an image covered in one part. How should i fix that. Jaymoh

Any digital single lens reflex camera body , rebel t3i, go to Canon's USA website and look at dslr cameras

Glad to hear you're back up and running :-)

That depends on what you compare it with.

It's larger and heavier than a point-and-shoot camera, but it's smaller and lighter than an high-end DSLR.

It has a smaller sensor than a high-end DSLR, giving poorer results, especially in low-light situations. It has a larger sensor than a point-and-shoot camera, giving better results, especially in low-light situations.

It's more complex than a point-and-shoot camera, requiring more time to learn how to use it well. It's simpler than a high-end DSLR, requiring less time to learn how to use it well.


It doesn't give you as much control over picture-taking settings as a high-end DSLR will, and many of the settings require going through menus instead of simple buttons and dials. This can make the D3100 slower in operation. It gives you more control over picture-taking settings than a point-and-shoot camera, and provides access to some of those controls through buttons and dials, instead of going through menus. This can make the D3100 quicker in operation.

The D3100 won't focus with lenses without an autofocus motor. Higher-end DSLRs will autofocus with any autofocus lens.

No two camera models are identical. Only YOU can decide which features are most important to YOU. How important is the weight of the camera? Do you want a camera that's easy to learn, or one that's easy to control?

There would be almost no noticeable difference between an 18 megapixel camera and a 20 megapixel camera. Personally, I would look for a camera with a fast shutter speed and a high Optical Zoom.

The Canon EOS D60 is a discontinued 6.3 megapixel digital single lens reflex (DSLR) camera.

The Canon EOS 40D is a 10.1 megapixel digital single lens reflex camera.

The Canon EOS 1D Mark III is a 21.1 megapixel digital single lens reflex camera, and is the first to break the 20 megapixel barrier.

Several reasons.

Interchangeable lenses. A wide variety of lenses are available for the pro bodies, ranging from ultra-wide fisheyes to super-long telephotos. Also macro lenses, defocus lenses, tilt-and-shift lenses, and others providing capabilities you just don't get on a compact camera.

Larger sensor. Smaller cameras by necessity have smaller image sensors. Packing the same number of megapixels into a smaller sensor means that each pixel is smaller. This cuts down on its light-gathering ability. Larger sensors are more sensitive to light. Trying to match the higher sensitivity on a small sensor leads to much more digital noise. In general, if you take the exact same picture with a pro camera and a compact camera, the picture from the pro camera will be of higher quality. Of course, if you never print your pictures larger than 4x6 or 5x7, you may not see the difference. But if you make a three-foot poster, you'll see the difference.

Larger sensors also allow the photographer to reduce the depth of field. One of the factors controlling depth of field is the lens focal length. Small sensors need shorter lenses, and short lenses have wide depth of field.

Speed of use. Compact cameras tend to be designed for the non-professional. They tend to be easy to use, automating many features and providing menus to hold the user's hand while guiding him/her through the non-automatic stuff. Pros don't need the hand-holding. They want to be able to control everything, or at least be able to if they need it. Rather than making choices in a menu, it's faster to just press a button and turn a dial. Of course, with all the settings possible, you need more buttons and controls, and you need a bigger camera to hold them all.

Unless I've left out something, I think those are the main reasons pros put up with the expense, bulk, and weight of their cameras and equipment. If anything I've said is unclear, please feel to free to respond with any additional questions.

This is normal. the lens stay at the largest opening so you can see to focus, then the mechanics will close to the setting when the exposure is made. This is part of the reflex in single lens reflex (SLR). This part staying open when you focus keeps lyou from having to open the aperture to focus and then close it to the correct setting to shoot the picture.

You will be guided by the instruction above. Let me know if this works. Usually you should set that to S2:1M.

1. Press the Power button, and turn off the HP All-in-One.
2. Unplug the power cord from the wall outlet.
3. Unplug the power cord from the back of the HP All-in-One.
4. Wait for 20 seconds.
5. Plug the power cord into the wall outlet.
6. Press and hold # and 6 while plugging the power cord back into the HP All-in-One.
7. Turn on the All-in-One by pressing the Power button ( ).

On a DSLR (digital single lens reflex) like your Rebel, the shutter remains closed until you actually take a picture. The camera cannot display an image on the LCD since there is no way to preview one that has not been captured.

This is a Single Lens Reflex Camera
As such it is not possible to take a photo via the LCD.
The image comes into the camera and to the viewfinder via a mirror.
When pushing the button to take the picture - the mirror lifts to allow the image to go to the CCD.
There is no way to change this with this model
