I bought a Sony DSC-H400 bridge camera December last year as I was just starting out in this big world of photography & it's been a great little camera but when the ISO is at 800 i'm now starting to notice more noise in the images which has got me a little worried, i've taken around 5000 images since getting the camera if that helps any
More image noise developing

Do you mean that the noise is actually increasing or that you are just beginning to notice it more?
At 800 ISO virtually all digital cameras will exhibit noise especially if the images are under exposed or in the shadows.
And with the very small sensor on the camera you have noise will always be a problem at higher ISO settings.
You could try a noise reduction program - I use Neat Image 3 which is very good but takes a bit of getting used to and experimentation to get the best results - fortunately you can download a free trial:

But if the noise is starting to really annoy you the only choice may be to start exploring the DSLR range of cameras with their bigger sensors.

I'm still processing the same amount as I was & used to notice a tiny bit of noise at ISO 800 but images were still nice & clear but the images I took last night had a lot more noise in them. Not sure if it's related but the lens seems to now have a bit of up & down play in it once it's zoomed out a little. My next camera will be a dslr once i've saved up for one

I don't think it can be related to the lens. Sensors can produce more noise when they get hot but I've never heard of one degrading over time. Doesn't mean it can't happen, though.

There are a lot of things to consider.
First, you should find an earlier shot with noise you are happy with and compare them to the recent shots where you are not happy.
Post them here too, se we can have a look.
Noise can become more apparent depending on a lot of factors. The sort of conditions you are shooting in will have an impact, especially if the camera is making decisions on how to process the photos (Raw or jpeg?)

Could of course be the presence of outside influences affecting the background levels of spatial pollution .which in turn convinces us that our current gear is no longer worthy and makes us buy new gear whether needed or not .least that's what I tell the wife when I need a new camera of lens etc .

Don't underestimate the effects of sensitisation. If you start worrying about noise and how to reduce it in your images you've in effect started your eyes and brain on a training course in the detection of noise. You will become better and better at seeing it. You will be able to see it very easily in places you never noticed it before. Keep at it and you will soon be able to see the noise in your own eyes. There's a helluva lot of that, but your brain has been very kindly been post processing the RAW images from your eyes to conceal it from you because it thought you didn't want to see it.

Are your noisier images shot in darker conditions? You'll notice it more in darker areas if the image is underexposed.
The camera won't be getting noisier, I've never heard of that, and can't think or any technical reason it might happen other than an overheating sensor and you'd only get that in *very* long exposures or super high def video when the sensor is overworked and heats up. The Sony DSC-H400 isn't very good at clean high ISO and it's known to be pretty poor at 800 + iso.

Most likely you're a) getting more picky b) under-exposing (causes worse noise) because it's a bridge camera with poor maximum aperture c) asking too much of a compact camera with a tiny sensor.
A technique for getting rid of noise in shadow areas without excessive noise reduction is to boost contrast to make the blacks more 'solid'. The noise will often disappear as the blacks darken, although there is a limit to what can be done.You could also try mounting the camera on a tripod to reduce camera shake and allow you to use a lower ISO setting.
If you plan to regularly shoot at ISO800 or similar and need low-noise pictures then this is the wrong camera for you, and you need something with a bigger sensor and a lens with a large aperture.
