I've been using a DSC-T7 very happily for the last year, but it suddenly started getting a massive amount of chromatic aberration. Has anyone else experienced this? The colours seem to seperate most of the time now. Especially (but not exclusively) when I use the flash.
I have not knocked it as far as I know (is it possible to misalign the sensors?)... or could it be humidity? Is there anyway to fix this?

Re: My T7 has developed severe chromatic aberration
Not everyone is happy with this camera, though most are.
It could be that your camera has developed a fault with the sensor, and I would suggest that you hurry and use the warranty if it's not over yet.
One thing that users of this camera agree on, is that the flash is poor. It's range is very limitied, and the camera just isn't built for indoor/night shooting. If you have the subject within the flash range, which I would guess should be around 2 meters, then it should be ok, otherwise it's not known to give good results.
If it gives poor results in full daylight, and the settings are default, then I would guess your camera developed a sensor problem.

Fungus in a lens is the end of the lens. It is living and eating the coating. The coating is essential for the characteristics of the lens. Without it, the lans will have more chromatic aberration, flairs and will not be as sharp. Although I have seen advice to remove it with acetone, please keep it dry (silica) and start saving for a replacement.
Is the lens clean? only clean with a lens pen or a very soft cloth. (one you would use to clean glasses) Purple also could mean lots of chromatic aberration that only can occur when the lens is not correct in place. Did anything happen with the camera? like falling or bending in a pocket?
It appears that you have already tried what I'd have suggested as a last resort. Apart from cleaning the contacts and removing the battery for 15 minutes there is not much that can be done.
In my opinion it is better to purchase new camera than to spend so much on this one. Note that sony may also charge you a checking fee if you decide to send the camera in hope for less costly repair than they estimated.
And yes, it would be fruitless to dismantle the camera if you are not qualified for this stuff. There are no user serviceable parts inside and also there are timed mechanical switches which can be difficult to reassemble without a proper schematic.
PS. Please do not use Vodka for cleaning electronic components as it contains small amount of moisture. Use Isopropyl alcohol.
Focus motor in lens assembly of camera is jammed and needs to replaced, you can get complete lens assembly from Sony if you wish to repair it at your own. Error code 61-10 shows focus problem in lens mechanism.
No. It is likely that there is still water in it. It's very important that you take the battery out and do not try to use it. Take it to a repair shop and be SURE to tell them it had water in it so they can take the appropriate steps to clean and protect it.
This is a component failure If the camera is less than a year old return it to the seller. If older than a year but a current model contact Sony who may replace it free of charge. There have been recall on some models because of component malfunction
Try this test:
Mount the camera on a tripod or set it on a secure base and use the self timer to trip the shutter. Doing this will totally eliminate any possibility of camera shake causing blurriness.
If the picture is still blurred then there might be a problem with the AF but if it isn't blurred then the problem is either camera shake OR subject movement (or both).
The zoom does not work on the T7 while you video, you have to zoom first and then start to video, then it is fixed at that zoom setting.
Other than that, the video is pretty good, I have taken video clips up to about 5mins (but in theory you can go up to the limit of the mem card and battery - battery from full is about 40 mins from the top of my head and my 512mb mem card could do about 30 mins on best quality)
The sound is good, and the picture is pretty good, but obviously there is no 'flash' function, so you are looking at daytime or well lit video only.
One thing is that you do need a steady hand, because the unit is so small (a great benefit most of the time) you do get a fair amount of camera shake if you do not have a very steady hand... usually the morning after the night before for me! :o)
I have been pretty happy with it a a fun video accessory, but if you want the camera for that as a main use, I would look around.
