Is A 5 Mega Pixel Camera Worth The Money?


I have had very little experience with digital cameras, and very little of it was positive. Up until I got my 5 megapixel camera, I thought that a film camera was the only way to go. This is because I gave up too early. All I had ever used was a camera phone. It had horrible resolution. I think it was something like 2.1 megapixels. It looked so blocky that it was almost impossible to tell what you were looking at.

Now that I have a Canon Powershot 5.0 megapixel digital camera, I know better. The image is brilliant. There is no other way to describe it. The digital camera has not replaced the film camera yet, but it has come close. Although a film camera still has a better picture, it is not that much better. Most 5 megapixel cameras definitely give old film cameras a run for their money. If the image is not quite as good, it certainly is close. Besides that, the advantages of using a 5 megapixel camera over a film camera are obvious. You do not have to pay for film or wait for the picture to be developed, and you can instantly see what it looks like. For all but the most professional photographers, a digital camera is surely the way to go!

Of course, there is a downside to a 5 megapixel camera. First of all, they are fragile. Cameras in general can be easily damaged, but much more can go wrong with a digital camera. There are a million different ways that the sensitive electronics can get ruined by being slightly jarred or banged around. Besides that, people steal digital cameras all the time. When I first got my 5 megapixel camera, no less than three people tried to grab it from me. Fortunately, each time I had it secured to the strap and was able to ward them off. Even so, I still react with caution whenever anyone walks too close to me if I am wearing my camera around my neck. I don not want to lose it, after all. It costs a small fortune.

Despite all of these downsides, I think it is still worth it. My 5 megapixel camera has really changed the way I see the world. It is an incredible experience to be able to capture any image that I see. Before, I had to carefully select every image. I never knew how it would come out until I had developed the film. Now I can see it immediately!

What To Look For In A Digital Camera



Digital cameras are expensive and if you are going to buy one you need to make sure that you make the right purchase. You work hard for your money and you need to know that you are getting your moneys worth. So make sure that you take the following into consideration before you make that final commitment.

Battery life
The life of the battery is going to affect just how many pictures you can take. This matters if you are going to the lake for the day or you are taking pictures of your son or daughters birthday party. There is nothing worse than having your camera run out of batteries in the middle of the day. You need to be able to trust your camera to do the job the right way. So find out what the battery life is before you make the final purchase and compare the different cameras and batteries to find the one that is most suitable for your needs.

Megapixel count
Depending on the use of your camera you may need a digital camera with more or less megapixels. These are what will allow your pictures to be sized. The more megapixels that the camera has the larger the pictures will be able to be without losing any detail. If you are a professional photographer and you often take pictures for posters and other large scale print materials then you need to have a camera that can handle taking pictures that clearly.

User controls
These are another important aspect of your digital camera. And again they will differ according to the camera. The options that you need will depend on why you are looking for a new digital camera. If you are getting the camera for professional reasons then certain options are going to be more important than others. Find out exactly what your camera can do and how easy it is to use before you buy it. There are plenty of user friendly cameras on the market for those who just want to be able to point and shoot. Just know your needs and you will have no trouble finding the digital camera that is right for you.

A wonderfully full-featured camera at an unbeatable price



Rimesh Patel (Washington D.C.)

I've had the T1i for about almost week now and after some extensive use, here are my thoughts:
1. 15.1 megapixel sensor. Yes, the high megapixel count is impressive, but keep in mind that, as you approach higher resolutions, you need to ensure the lens on the SLR can resolve that much detail. Sadly, the included 18-55mm IS lens is functional, but the high resolution really shows the so-so quality of the lens. Even if taken at the proper focus, pictures can appear soft with this kit lens. Shots I have taken with Canon EF-S 17-85mm and EF 70-200mm L lenses are crisp. I don't have any gripes on image quality. There are some issues with noise on the higher ISOs that don't seem to show up on the Nikon digitals, but overall, the quality is amazing for the price. Skin tones, textures, colors are reproduced very accurately.

2. Digic 4. The Digic 4 processor appears to process/save the 15 megapixel images in the same time (if not faster) than the Digic III processor on the XSi (even in RAW+Jpg mode). I have also noticed that at higher ISOs, the sensor and the Digic 4 produce images with less overall noise compared with its predecessors.

3. LCD. The 920,000 pixel LCD screen is large (3"), crisp, vibrant and fully visible even in bright sunlight. In comparison, the Canon XSi SLR (which the T1i replaces), also has a 3" LCD, but with 230,000 pixels. The viewing angle is great as well and the LCD can easily be seen nearly 180 degrees around.

4. ISO 12800. Canon and Amazon are correctly identifying that the T1i maxes out at ISO 3200. Some less reputable dealers are listing an ISO 12800, which you should disregard. The ISO 6400 and 12800 settings are expanded ISO settings. The pictures taken on these two settings are ISO 3200 images pushed to ISO 6400 or 12800 by the Digic 4 chip before saving to the memory card. These pictures are extremely grainy and contain a lot of noise to the point of only being usable as for snapshots or adding an artistic effect to certain compositions.

5. Penta-mirror. That Canon is still using one in the T1i is disappointing. The penta-mirror viewfinder image is functional, but still noticeably darker than that of the penta-prism viewfinder in the Nikon D90 (which is the T1i's main competitor). I really would have preferred if Canon had kept the XSi's 12.2 megapixel sensor, forgone 1080p video altogether, and maybe upped the cost of the camera slightly to cover the production cost of using a penta-prism in the T1i. Honestly, unless you are massively cropping your images, or creating large photos, the difference between 12.2 and 15.1 megapixels really is negligible.

6. Size. This is the same body as the XSi, and therefore a bit on the smaller side compared to other digital SLRs. I have small hands, so the T1i is comfortable for me. If you have big hands, I can see this being a very difficult camera to use over an extended period of time. If you haven't handled a Canon XT, XTi or XSi, I would suggest you go to a store and hold the T1i yourself before purchasing it online. (I will upload a picture of the T1i in my hands to the user gallery for a size reference.)

7. HD Video. Yes, the Canon marketing department made a horrible marketing decision and pushed the T1i onto shelves limiting the 1080p recording to 20fps (frames per second). Recognize this as a marketing gimmick that allows them put a 1080p sticker on the camera box. The 1080p @ 20fps is fine most times, but seems a choppy if you have a lot of action in the frame or are panning quickly. The T1i's 720p video is recorded at 30fps and is clean, smooth, and sufficient for all but the most discerning consumers. One major criticism though is that the sound is recorded in mono, AND there is NO input for an external microphone.

A lot of pre-production reviews of the T1i criticize its inability to automatically autofocus while recording. I wouldn't put much weight in this criticism, mostly because neither of the other two SLR cameras with HD recording capabilities (Canon 5D Mark II and Nikon D90) can automatically autofocus while recording either. What you can do with the T1i is pan/zoom the lens and then press the AE lock (*) button to make the camera autofocus on the new subject (all while recording). A problem with using the AE lock button to have the camera autofocus is that the microphone for the camera is on the front upper left of the body near the lens mount. Therefore, the lens motor noise is picked up just as much as ambient sounds. Even with my quietest Canon USM (ultasonic motor) lenses, this lens motor sound is pretty loud in video playback. Although, remember, you can always manually turn the focusing ring on the lens to get your subject back into focus. It's not easy, but after a little practice, it's not all too hard, either.

Ultimately, you shouldn't let the HD recording limitations sway you one way or the other. This is an SLR camera -- not a video camera. The HD video is a great feature, but if you're looking for something primarily to take video, look elsewhere. There are much better, cheaper VIDEO cameras out there which can record true 1080p.

8. Record button. For some reason, the record video button is next to the LCD screen (the same button used for direct printing). The first few times you take video, you'll intuitively find yourself using the shutter release button used to take pictures. The reason for this switch is that you can take a still picture while recording video, although, doing so will interrupt the recording.

9. Battery life. My first fully charged battery only lasted about 250 shots (no flash), but all charges since have given me in the range of 500-700 shots per charge. I'm guessing the first charge had such a short life because I spent quite a bit of time learning the camera, its menus, and settings.

10. Live View. I honestly can't review this as I haven't used it too much yet -- I prefer using the viewfinder. One feature I can say is nice is that, on the LCD, you can digitally zoom in (up to 10x) on a section of your shot to ensure it is properly focused. This, and the fine focusing, can really help if you're into macro-photography.

11. HDMI cable. The T1i has an HDMI Type C output on the body to allow you to directly display pictures and video on an HDTV. A minor criticism is that the HDMI Type C cable is not included in the box. You have to buy it separately. It would have been nice if it were included, as it's not an expensive cable.

Conclusion. The T1i is a bit on the light end, yet the construction still feels solid. For the camera's price point, you'd be hard pressed to find any digital SLR out there which gives you all the capabilities and growth range of the Canon T1i. The camera is intuitive enough for those new to photography to pick and learn easily, yet configurable enough for advanced amateurs. If video is not a big deal for you, then get the Canon XSi. There is very little the T1i has (other than ISO 3200 and a sharper screen) that the XSi doesn't. Plus, with the release of the T1i, you can probably pick up a used XSi for a great price on eBay. My wife recently gave birth, and I'm not looking to record endless (never to be watched) tapes of video footage of our son, but I do want several minute clips of him as he grows through the years. I've always been more inclined towards photography, so this camera gives me a very versatile digital SLR that I need with the wonderful capability of recording HD video that I want.
