What was I doing wrong?

Hi Guys,

Went up Snowdon last Saturday the aim was to be up and down within 4 Hours (some guys I went with did it in 3 ) so I didn't have much time to stop and take photos (mess around with camera settings etc)

Most of the photos I did take though... Actually I better tell you my Camera first, I've just got a Canon 500D with the 18-55mm IS Kit Lens

...Back to my point, at the Lenses widest I've got horrible circular blurs in the corners of my photos, I'm guessing this has something to do with light not getting to the sensor or something (I'm a complete newbie)

Any advise so I don't end up with this again or could it be a faulty lens!?

Examples

Cheers
Zaf,

I dont have a Lens hood!!

I do have a 7Dayshop UV Filter attached though, would have thought it would be that close to the lens it wouldn't get in the way

I only put it on to protect the lens nothing more! But if I buy a £20 Canon one you're saying the fall off will go away?

Isn't it the fitting of the fillter creating the fall off though not the glass, would have thought 7Dayshop filter would be the exact same dimensions as a Canon one just lower quality glass (plastic?)

So much to learn hehe

I was there on the weekend too, took 3 hours to get to the top via Llanderis route on our bikes (few not so fit riders with us so plenty of stops).






25 minutes to come down Rangers,

Sounds Awesome! I'm in training for the National Three Peak Challenge next june so should hopefully be getting some better pics from The Ben and Scafell

I also went up on Saturday, no wonder it was so ****** packed!

We set off at 5:55am got there for 8:45am and the main car park at start of Miners/Pig track was already full!
