Default Fringing when looking through viewfinder of 550D

Hi,

I was wondering if any other 550D owners (which is great, by the way) are experiencing fringing when looking through the viewfinder. In my case, it is yellow/blue fringing, and it seems to change depending on how I position my eye (I'm talking about very small movements here). It is quite noticeable, up to the point where it is distracting. However, the pictures turn out fine and without fringing. Also, the effect seems to be independent of the lens I use.

Any ideas? Is it normal? I've never experienced this with previous DSLRs.

Thanks,
Alex

I haven't noticed it but I'll check. Same with different lenses?

I do really like this little camera. Wish they'd make a FF version!

Thanks, I appreciate it. And yes, it happens with all my lenses (which doesn't make sense to me).

Try it with a subject with sharp edges. It's most noticeable there.

Yes! My hunt for affordable yet fast wide lenses would be over ;)

How fast is "fast?" You can have a lot of fun and get a lot of dandy results with a 15mm f/2.8 fish on a 1.6x crop, either de-fished or not.

I wonder if this could occur if the entrance surface of the pentaprism wasn't perpendicular to the axis of the incoming light....ie, a slightly skewed pentaprism or the mirror not quite resting at 45 degrees?

Nill,

Off topic, but how do you manage with just one scroll wheel? Is it confusing?

Hi!

I'm totally new to photography, but I recently bought the 550D and I noticed that too. But then, I onyl have the kit lens so far (cause I'm not good enough for the real stuff yet), so I'm nt sure whether it's a lens or a camera problem.

Would you mind explaining what could be causing that? i.e. what that fringing is?

thanks!

Not happening on mine, Alex. I've used several lenses with it. My viewfinder is edge-to-edge clean. I suggest sending it for service. Something's out of alignment.

Not at all. The Q button takes you straight into all the settings, which are very easy to see and access on that big beautiful screen.

Thanks for all the answers. I suspected that something is wrong.
Great. Of course, something like that has to happen one week before I leave for LA. Oh well.

I'm not so sure, Hannah also experienced something like that. Could it be dispersion from the eyepiece diopter and the penta mirrors? It doesnt affect the image itself, does it?

Cheers,
Bart

Hi Bart,
Yes, it doesn't affect the image. What exactly it is or why it occurs, however, I don't know, as I don't know enough about camera manufacturing. Quite frankly, I'm puzzled. It is pretty noticeable, too.

@Hannah: How noticeable is it in your case?

I looked, and I don't see it.
