Hi Team,
Noise - seems to be something I struggle to deal with. Been a lot of talk about the 50D and noise and it does raise itself as an issue now and then in my photos. I know I shoul dbe shooting with filters for sunset / sunrise photos and I am off to purchase a Cokin Grad filter kit on Monday. However, I am just wondering if what I am seeing in my 50D noise wise would be consiered normal

I admit it only seems to be an issue low light and not neccessarily long exposures but I keep second guessing myself if the level of noise I experience in my camera is normal or do I have a sensor issue.

Below photo with 100% crop was taken on AV (Aperture Priority) with my Tamron SP 17-50 @ 23 mm, ISO 100, f10, WB auto, evalutive metering.

Would other 50D owners and Canon owners alike consider the noise in the crop normal. Shot in RAW and as the lens flare would indicate no post processing apart from coversion to jpeg.
