Bug on element 85mm f/1.8

<p>Alright, I'm not sure how this happened, but today I noticed there was a bug on the element that moves when focused. I cannot shake it off, and it seems just stuck on there. No idea whatsoever how this happened. Its less than a year old, but I feel this isn't canon's fault just bad luck. How much would it cost to get removed?</p>

<p>Instead of taking a picture of it, let me try describing it. This bug appears about the size of the ball on a push pin, but this seems to be because of the magnification.</p>

<p>I notice its not coming out in the photos, but its bothersome to have there. Any ideas?</p>

<p>If it's visible in the viewfinder but not in photos, then I would guess it isn't in the lens, even if it seems to move when you focus. More likely it's in the camera, perhaps on the focusing screen. Is the bug still there if you change to another lens, or simply remove the lens without putting another one on?</p>

<p>Something that small will not affect the quality of your images in most cases. Maybe if you are shooting backlit, you might see something. I have some older lenses with bubbles the size of a pin head and nothing ever shows up in the photo. </p>

<p>You mean on the inside surface of the front element right? Otherwise you could wet clean the little sucka right off. Front elements are easy to take out by removing the front retaining ring. </p>

Sometimes the light’s all shining on me. Other times I can barely see.

<p>I notice it isnt really affecting the image, but for peice of mind sake, and so I know it won't get worse, I'd like it removed.</p>

<p>And puppy face, its not the outer most element. Its on the inside, and when you focus it, the element the bug is on appears to be moving forwards and backwards.</p>

<p>Dead bugs are a good starting point for fungus.<br />So better store the lens right (normal dry air, not Peli cases for months..)<br>

I think that was a bug, but I had a even more bug like looking one.<br>
