Where can I find results of long term tests on digital cameras?
For car enthusiasts , you will find some car magazine or websites
showing the performance of a car after it was driven 1, 2 or 3 years or more. Is there a website for camera or photography readers where test shots were taken and compared for cameras after they are used for a while? Example: when it is brand new, after 10,000 shots, 30,000 shots, 50,000 shots, etc. I like to see whether some cameras (perhaps the pro cameras and expensive ones) perform better than others and do not degrade the picture quality with time after being used for a while. Or, is it because of the modern electronics that some elements of the cameras breakdown suddenly (therefore there is no degradation of picture quality... ie. only good picture and then no picture at all if they break down). I am not talking about exposed mechanical parts, like the battery hinges, or the LCD monitor, but more for the elements that produce and process the pictures (shutter, sensor, processing engine, inside mechanical parts that making the auto focusing, etc.). My Lumix's 3 MP camera has over 60,000 shots over 4 year period and still going strong. But I am not very sure if it produces the same picture quality pictures as when I just bought it. The other day, I went to the attic and found an old photo taken by my Nikon One Touch P&S pocket film camera (1980s) and I could not believe how excellent and sharp the picture quality of that photo is. The camera is still working now (after 20 years), but again I don't think it produces the same picture quality. Thanks for info. |

nowhere. Manufacturers aren't interested in longterm performance but rapid
obsolescence. Cameras and their release cycles are designed around the cameras being replaced every other year (roughly) as soon as a new model hits the market. The marketing campaigns are created to impress on potential customers the fact that any model older than the current production model is utterly useless and cannot produce a halfway decent image under any conditions. As a result a large proportion of the customerbase indeed replaces their cameras every few years (people are gullible herd animals, most of them) and often don't bother to try to sell the old equipment because the resale value is minimal. Instead they keep it around for a while as a backup (just in case) and then dump it in the trash, even though it's still in perfect working order and capable of producing results of the same quality as what they did when brand new 2 years earlier (and likely not visibly worse than their new equipment). In such an environment it's not in the interest of camera manufacturers to encourage such endurance tests as you are looking for. And as all or most publications depend heavily on advertising revenue provided by those manufacturers it's not in their interest to publish such tests either. |

If you keep your equipment dry and clean it will last almost indefinitely. Humidity can get inside the camera and allow corrosion and growth of bacteria. Dust eventually gets inside even the best cameras and lenses as seals dry and wear out. Complete disassembly and refurbishing is possible but very expensive. NM |

A car can have serious things wrong with it and still chug along nicely. Underinflated tires, dragging brakes, valves needing adjustment, dirty filters, all these things can degrade the performance of a car, and most folks would barely notice, if they noticed at all. A camera depends on most everything working Just So, and if it doesn't, it won't work at all, or it'll work so poorly that any problems will be glaringly obvious. Modern electronics (by 'modern' I mean 10 to 15 years old) are fairly reliable. It's not unusual to lab test solenoids and switches to 100k to 1 million cycles. With digital cameras, as well as some (most?) film cameras, mechanical parts have been mostly replaced with electronics, which are less tolerant, as well as less vulnerable, to wear, tear, misadjustment and failure. So, a 10 year old camera with average use should, in theory, work just as well as a brand spanking new camera, barring abuse and the odd faulty part. The sensors used in digital cameras are, as far as I know, either immune to degradation over time, at least for the period of time that's relevant (digital cameras have been in popular use for roughly 5 years or so, with the hard core crowd roughly 12 years or so, and I've heard of no issues with either CMOS sensors, which are fairly newish, or CCD sensors, which are the oldest. Number of exposures don't seem to be an issue. The same type of sensors are used in survelience cameras, working 24/7, in by far a more harsh environment than any still camera, and they can go on for years with no problems. So, a 'long term' test of a camera, at least in a review style comparing models and such, would be kinda silly, especially considering the work involved. A photo would have to have been taken when the camera was new, then the exact same photo taken after 10 or more years, for a real comparison. Someone would have to gather a bunch of old cameras, which would be a hassle. Then, as others have mentioned, there's have to be some significant reason to spend one's time doing all this. I doubt Nikon or Canon would chuck in money for something that may cost them sales. With a little investigation, you can find out for yourself which cameras stand the test of time. Word of mouth, newsgroups, and photographer friends are sources of information. Simply ask folks what they use and how they like it. You can also check out Ebay. What are folks paying for used digital cameras? Some, like my poor Nikon 5700, are going for roughly 20 to 30 percent of the new price. That's actually not too shabby. Some real good cameras are going for about 1/3 to 1/2 of their new price. Normally I wouldn't rely on other people's foolishness for making my own decisions, but in some cases, like this one, I feel it's pretty reliable. Most fools aren't going to spend a lot of money on something that goes against "common wisdom", said wisdom being More Megapixels = Better Camera = Worth More Money. If folks can buy a 10 megapixel camera that's small and easy to carry around for $300, they aren't going to go on Ebay and spend $600 on a 6 megapixel camera that's big and bulky. A large LCD display on the back that works as a viewfinder is much more fun than a tiny screen that only shows the shots you've already taken. Why go with an "enormous" compact flash card when SD cards and memory sticks are so much sexier? In essence, while you can't always rely on people's smarts, you can ALWAYS rely on their stupidity. heh CS |
