SLR Digital Cameras - Why Have A SLR Digital Camera

In the modern day of point and shoot digital cameras, it has to be queried as to whether there is any place for the SLR digital camera any more. Well for the fans of SLR rest assured as SLR cameras are still being made by companies such as Canon, Minolta and Olympus to name but a few. As you are already probably aware SLR cameras are bigger but have more options, and for this reason SLR cameras tend to be more expensive than point and click ones. But what exactly is an SLR camera

SLR stands for single-lens reflex. This means that the composition and metering as well as the actual film exposure are being done through a single lens. Another way that these types of camera are known is TTL (through-the-lens). As cameras go, SLR has been the favoured type used by professional photographers for decades. The reason for this is that SLR cameras offer a direct view between your eye and the target of your pictures, which ensures a photo reflecting your vision. One thing that you do have to be wary of though is that, unlike the old fashioned more robust film versions, digital SLR cameras are quite sensitive and easily broken.. The reason for this is because there are a lot more electronic components to a digital SLR camera than there were on film cameras, and once these are damaged, you probably will need to get a replacement, although repairs may be possible. But do not let that deter you from buying one, as if you look after it properly then the vast majority of digital SLR cameras sold work perfectly well for a long time, and give you good quality images for years to come.

One of the qualities and even an advantage of using a digital SLR camera, is that it is generally easier and faster to shoot and it tends to be more flexible than a normal camera. This is because it generally allows you to be able to change your lens as a feature. And quite often with digital SLR you will get an Auto focus feature. This feature enables automatic focusing and will help to give you superb image quality even in situations with low light availability . If you really push the boat out and invest in a really professional digital SLR then you will find that these use the best sensors the camera manufacturer can produce, resulting in exceptionally clear, vibrant images. But even if you just get a standard camera, you will find that the lenses made for SLR cameras are generally of a higher quality than those found in most point and shoot cameras, so you are always going to get a better final image.

A Few Tips on Used Digital SLR Cameras

Digital cameras are expensive to repair for a few reasons. If you have ever broken your digital camera, you know that usually you do not bother having it repaired after visiting the local electronic store and finding out how expensive it is. The reason for them being so expensive to repair is because they are built so compactly and with several components inside. This makes it hard to take it apart, and put it back together as the manufacturer did. You will need special machines/equipment, and these can cost a fortune (so it is probably not worth it, unless the camera has some value under it to you).

Digital cameras run into many problems. One of the most common problems is that the lens stops working (the zoom lens to be specific). Your zoom will either not work, or you will receive an error message on your screen. This is a commonly a result of the zoom lens being out of alignment.

Another common problem is that the hinge on the memory card door brakes. This is quite often, almost as often as the zoom lens issue. The battery cover may also be broken or scratched, or a broken LCD. The inside (where the memory card is inserted) can be become damaged if a memory card is forced in the wrong way.

Before jumping to the conclusion that your digital camera is broken, you should do a few things. You should check if the battery on your camera is low, because this will cause a camera to not function properly. Try charging the battery and see if this solves your problem. Secondly, be sure that no one has altered the settings. This is a common mistake. You should be able to reset settings to the factory default. Also, when a memory card is full, the camera may not turn on (this only applies to some digital cameras).

If your camera is really broken, contact the manufacturer. Maybe your camera has some sort of warranty. If not, find out how much repair and shipping will cost. Sometimes companies will repair it for free, but this is not extremely common. It is always good to get warranty when you purchase a camera, because you never know what is going to happen. All in all, if your camera is really broken and you cannot get it fixed for free, you are better off just buying a new camera. Be careful and take care of your digital cameras!

Digital SLR Camera Comparison Guide

This article is about a digital SLR camera comparison, between four models: Nikon D40, Canon EOS Digital Rebel Xsi, Nikon D90 and Canon EOS 40D.

Canon EOS Digital Rebel Xsi

When it comes to value and performance, the Canon Rebel DSLR has the best balance between the two. Whatever setting you use, either manual or automatic, the quality of the photos is very good. One of the features that are included with this digital camera is the Live View included in the 3 inch LCD. With the Live View, you can see how the shot will look like before you take the photo. The photos are sharper since it comes with an image stabilized kit lens and a sensor cleaner.

Nikon D40

The Nikon D40 comes with great photo quality and a lot of customers gave it great reviews. The drawbacks are the resolution and the speed of the camera. The Canon EOS Digital Rebel Xsi is better in these departments. If you only want to make some regular prints, 8 by 10 inches, then the 6 megapixels of this camera will be more than enough. It comes with a clear and bright 2.5 inch LCD screen. You can take photos at a maximum speed of 2.5 frames every second. If you want to take sports photos, then this camera will not suit your needs. Another problem is that it doesn't focus well when the light is dim.

Canon EOS 40D

The Canon EOS 40D is a bit more expensive than other models, but the review seem to indicate that the extra money is worth it. The things that make it worth the price include the magnesium camera body which is sturdy, the fact that it's water resistant. You can also do action photos with it, since it can take 6.5 photos per second. The camera also comes with a sensor cleaner that is built in, Live View and an image stabilized kit lens that is optional. While the Nikon D300 offers similar performances, it costs much more than the EOS 40D.

Nikon D90

The great advantage of the Nikon D90 is that it can shoot videos, something that most other SLR cameras can't do. The 3 inch LCD screen has LCD, which allows for the movie to be made on it. The movies are made in 720p HD format, but its features are limited, so don't buy it if you want to make movies regularly with it. However, if you want to take photos, the 12.3 megapixels insure that the quality is very good, and you can clearly see that it's better than the D80 here. The shooting speed is 4 photos per second, which is less than the Canon 40D.

François l'embrouille - Le responsable d'une foire (HD)

François l'embrouille - Le responsable d'une foire HD Camera cachée François l'embrouille Camera invisible François l'embrouille Extrait des Best ouf de François l'embrouille François l'embrouille ... François Damiens, né à Uccle en 1973, est un comique et acteur belge. Connu en Belgique francophone pour ses caméras cachées réalisées pour l'émission Si c'était vous aux côtés de Jean-Michel Zecca et Mike (sans avoir travaillé ensemble sur les mêmes caméra cachés), diffusée sur RTL-TVI, il se lance en 2006 dans une carrière cinématographique, avec notamment des rôles dans OSS 117 : Le Caire, nid d'espions et Dikkenek, film qui a fait connaître François Damiens en France et en Suisse. Ses différents rôles François "L'Embrouille" a fait plus de 150 caméras cachées, chacune sous différentes fonctions professionnelles. Entre autres : Vendeur de chaussures, chef scout, juge (pour les chats), juge (pour le tunning de voiture), glacier, pharmacien, taxi (là où il a piégé la plupart des vedettes), serrurier, etc. Pour se faire encore plus discret, François a abandonné les professions pour se faire passer pour un touriste. Entre autres : Joueur de golf, élève dans une école secondaire, vélo-cycliste, un voyageur blessé ayant crevé un pneu, skieur, etc. Certaines caméras cachées emploient un ou plusieurs complices (jouant plus ou moins un rôle de figurant) pour piéger une personne afin de ne laisser le moins de doutes possible aux victimes. Par exemple : Élève dans une école ...

The 5D Mk2 is a Very Good Canon SLR Digital Camera

The good aspects - The Canon 5D Mk2 is a very good choice if you want to buy a DSLR camera that is full-frame. I used to have a Canon 1DS Mk2, but this new model is more sensitive to light by at least one F-stop. It also has an accurate and fast auto focus system during single shot mode. Also the auto-exposure system is more is more accurate than the one on my former camera.

The LCD screen is pretty impressive. It has a 3 inch LCD screen with 900,000 pixels. Menus are easy to handle and understand and "Live View" will surely impress you if this is the first time you own a DSLR with this feature. But keep in mind that it is a battery drainer and once the imager circuitry from the CMOS heats up the live-view will be automatically turned off not to add noise to the images.

The battery grip of the BG-E6, which is optional, is also a very good accessory to take into consideration, as it's a lot easier to hold the camera taller using it.

The bad aspects - When in camera mode you don't have any control over shutter speed, ISO setting or iris. It has a lock button which you press when you think you've got the best image that the camera automatically adjusts in the settings area. The thing is that after each photo, the lock resets, so you risk in getting non consistent exposures when trying to repeatedly take a scene. You can only adjust the temperature setting.

The camera can only record at 30.00 frames per second instead of 29.97. It looks like a small difference, but due to this you'll need to modify every single file's header with Apple Cinema Tools or some other similar program before editing the movie you made and turning it into a regular broadcast, at 30FPS and 1080i/1080P. If you don't do this you'll have to render every single scene on the 30 fps time line, resulting in some skipped frames or just set up a 30.00 fps time line.

But this is only a problem if you're shooting for film or television, as no such broadcast operates at 30.00 fps. If you're using this camera only for web released videos, the 30.00 fps won't be a problem to you.

Another thing is the camera records audio using a sample rate of just 44.1kz when the standard is 48kz. Only Apple's Final Cut Pro can work with this file at any sample rate. As I've said before, this won't be a problem if your videos are for uploading on the Internet.

Also you may notice the H.264 block artifacts in some low light or low contrast scenes. I could say that these artifacts are more obvious than the Canon's HF10, 1080 video camera encoding.

The video is noise-free except for red. You'll especially notice this when shooting in shadow areas.
