Help for a newbie, please ;)

[Pinkfairy1978]

took some photographs today and noticed that i had some squiggly lines come up on some of them, I used a prime lens for most of my photographs today and haven't noticed them but when I used my 'zoom' lens 70-300mm they appear?? does anyone know what they may be and suggest any help i can get to remove them. Thank you in advance

also, forgot to add that i done the white paper test and these lines show up on both lenses ;(

That's odd; if the dirt pattern is identical regardless of lens, that pretty much only leaves the sensor, but that seems too well focused to be on your sensor. Have you cleaned the front & rear elements of both lenses and looked at them carefully under good light to ensure they're clean?

Time to clean your sensor. It's really dirty.

Ah-yep!

 

[tirediron]

I ain't never seen sensor dirt that well focused... have you guys?

 

[SCraig]

No, but really that's all it can be. Showing up on two lenses eliminates the lens, and as you said that only leaves the sensor.

 

[tirediron]

That's why I'm wondering if maybe both lenses are just reallllly dirty?

Thanks for the advice, it just seems really odd to not be showing up on some shots but is really clear on others, I will be off to the camera shop in the week then to get the sensor clean. Does anyone know the average price in the UK for this as don't want to be ripped off!! have added 2 more photo's (please excuse the 2nd one but this was taken (quickly!!) with the 70-300mm camera and the 1st with the prime lens??

The reason it's not showing up in some shots is likely due to the aperture you're using. Try this: Put one lens on the camera, set the camera to aperture priority and f16 and shoot a blank wall/white paper. Then, put the other lens on and do the same thing, then post those two pictures. If the dirt patterns are identical on both images, then it has to be sensor dust, If they're different, that it is, as I suspect, rear element dirt.

Sensor cleaning is easy and NOT something you should pay a shop for. Reposted:

Sensors are EASY to clean yourself!
Reposted "John's How to Clean Your Camera's Sensor":

sensor cleaning is easy, and difficult to really screw up (That's NOT a shot at you bazooka!). IMO, it's one of those basic maintenance procedures, such as de-fragmenting your hard drive, or changing the oil in your car, that if you cannot do, you have no business operating that piece of equipment.

Here's my stock 'How to'...
Sensor-cleaning. It's easy to do and should be considered routine maintenance. Spending $50 - 75 for something that takes, literally five minutes, is foolish IMO. Do it yourself, save time and money, just be careful!

DON'T be scared of cleaning your camera! All you need are the right tools. I'll repost this just for info:
Contrary to popular belief, cleaning your own sensor is easy, and difficult to screw up. You should have a few tools though. My preference is for the Visible Dust line of products, in particular the Arctic Butterfly; it's a little pricey, but worth it.

Get a Giottos rocket, DO NOT use one of those cheap blower bulbs with a built in brush. They're dust/lint traps. Remove the lens, and holding hte camera at a 45 angle with the lens opening pointing down, thoroughly blow out the mirror chamber. Now, lock up the mirror and clean off the sensor. Once you've blown off the "big chunks" use the Arctic Butterfly to clean off the small stuff following the instructions provided.

If that doesn't work, then you may need to go to a wet cleaning system, which is a still easy to do. In ten years of digital photography, I've never had to use a wet cleaning system on any sensor.

Remember that you're not actually cleaning the sensor, you're cleaning the low-pass filter in front of the sensor which is usually made of mineral glass or other very tough material. It's actually quite difficult to scratch or damage. It is easy to get streaky if you **** up with a wet-cleaning system, but that's not permanent.

Buy a cleaning kit and do it yourself.

Ok just took 2 quick shots rubbish lighting indoors but def. showing on both lenses, first is the 1.8/50, 2nd is the 70-300

 

[Pinkfairy1978]

thank you all for your help, this really is greatly appreciated xx

 

[tirediron]

Has to be sensor dust; I've seen it like that before, but there's nothing else it can be.

 

[Pinkfairy1978]

thank you, will be purchasing the items you have mentioned and will clean myself at least it will save me the time and trouble of finding a good camera shop i can trust xx
