does anyone know about the sensors in an DSLR camera and if they run out or anything like that.
 
ok so im looking to buy a used dslr camera and somebody told me that the sensors run out after so many shots. Ive never heard of anything klike that so i have no idea what he is talking about.
 
weird, I've never heard that. And I don't see what the sensor would "run out" of.. It's not like it using something..? I guess the mechanical components of the camera wear out over time. What camera is it, and how long has it been used/ how many shots has it taken (if you know)?
 
its a nikon d70 18 months old and said its in good condition so im guessing not too many but i dunno for sure
 
yea every 20 or so shots, the sensor runs out.

no but seriously, sensors don't run out, so long as they're kept clean and dust free they'll last for as long as you want, only thing which can happen is the formation of dead pixels, but on-board software on newer cameras covers that up, and any decent photo-editing software would do the same.
 
well where the film used to be on an slr there is now a plate(sensor), the plate detects the photons (light) striking it, and it produces an image based on that, most dslr's have a sensor which is smaller than 35mm (normal film size) as far as canon goes, anything above a 5D has a full-frame sensor

Just thing of the sensor as the film film
 
Nah, you won't need to worry about that. With normal use, the worst that could happen it gets a bit dusty and that can be cleaned.

 
Yeah, if you don't know what you are doing you can really mess your camera up when you lock up the mirror and try to clean the sensor. I think what you heard about the "sensor going out" i think what they meant was the shutter going out. However, the cameras today are tested so much in conditions they will last.

I wouldn't worry. I have over 25,000 shots on my D200 and it runs like its new.
 
Sensors can just get dust on them, newer cameras, like my 40d, have an automatic cleaner so that never happens :D
 
word, the 40D has an epic sensor cleaner, never seen a spec o' dust on mine, the only time I've ever seen dust is when a bit gets on one of my lenses, that's when it really notices...

if you dont want to clean your lens yourself I expect a shop could do it for you, but if you're careful and buy the right cleaning stuff, should be fine
 
if your worried about your camera because your getting a lot of noise on your shots, its probably dust. It'd be much cheaper to get it cleaned than buy a new sensor or even camera, but i dont understand what your trying to say
 
ok well im not worried about the sensors anymore

just for the shutter will anything happen to the shutter after a lot of use and if so what can you do?>
 
wow, you do worry allot, shutters on modern cameras are good for hundreds of thousands of cycles, the timings are checked by quartz and on-board chips in most new cameras, so the chance of it being out is remote, only at very high shutter speeds will most problems become noticeable, if you take 3 shots at 1/8000 and they all look "right" then chances are there isn't a problem, but unless the camera has been totally trashed by the previous owner, I'm guessing the shutter timings will be fine, I have a Mamiya:

that thing was the first camera to feature metering, it's so old I found a roll of film with dinosaurs pictured on it, and I can assure you, it's ancient shutter is as accurate today as it has ever been...
 
ok thanks and ya i just want to be sure im new to dslr's so i dont want to have to spend more maney after i get it just to fix it
 
cool, no probs, judging by previous posts its the D70 your getting, right? if it is then it's only been out since 2004 so it's probably fine, just check it out before you get it, make sure it's working properly and put it through it's paces, enjoy :)
 
ya its a d70 and theyve only had it for a year and a half and theres still a 3 year warrenty on it
