Ever since I got my 17-40mm 4.0 there have been spots that show up on every picture I take with it. I have gently cleaned both the front and back glass and yet, the spots have stayed. I cannot see the spots when I look at the glass from either side. Is is possible that there could be something on the glass inside of the lens?

BTW, the spots don't show up when I shoot with my 50mm, so I don't think it is an issue with the image sensor.

spots are on your sensor...

you dont see it with your 50mm cause... well, i can only assume you're using the 50mm for a wide open aperture like 1.8 or 2.0... and with those apertures it gets diffused so much...

shoot your 50mm at f/16 into a blue sky, or a white wall... it'll be there..

then come to first photo and we'll clean it for ya...

what he said. They are the major bane of digital (SLR) photography. The clone tool is a good remedy in a pinch.

Okay, I will bring it up to First Photo soon to have the sensor cleaned. Thanks!

Edge, I have been using my clone/heal tool a lot lately. It's just a bit too tedious to keep doing it though!

you *could* have some bigger specks on an internal element but if im not mistaken the 17-40 is DWR so it shouldnt...it might just be sensor...

wap: you're right about the 17-40, it is sealed. i would guess its the sensor as well.
