Burned artifacts in viewfinder!

Has anyone else seen this artifacting? I received the XF about a month ago. Love it. I've used it several times and the other day I was using it outside in bright sunlight. After an hour of being outside, I noticed in the rear viewfinder a few bright green blobs! Then , , , a larger fleshy colored little design!! OMG!

Interestingly it was NOT in the LCD screen, nor in any actual video shot - just brightly colored in the rear viewfinder. The artifacts are in the same place whether looking thru the "camera" position, or the "media" position. But again, NOT in any actual video.

I got a new camera (B&H graciously exchanged it - with Canon's permission).

It's been great for 2 days and all of a sudden, I'm seeing more of the same after shooting outside again! Now, I'm as careful as the next fellow and take caution NOT to point the lens or viewfinder into the sun. That's not to say that if I'm walking outside holding the camera in a normal fashion - that for an instant or two, as I turn, the sun might not peep into the rear viewfinder without my knowing it . . . but apparently it is (I'm thinking this is what caused this?).

But I've been videoing for 20 + years - I've NEVER had anything like this happen. Now, in one week - it's done it to two cameras?
Anyone else had this happen? At first I just thought it was the first camera was flawed . . . but now???

I'm not sure it is the sun - it's just coincidental that two times outside = 2 flawed viewfinders?

I hope I'm not alone on this issue??
Thanks,
Larry

Hey Larry, that sucks.

It sure sounds to me like direct sun got into the viewfinder, but then again, you said you've been careful, so who knows? For your sake, I hope it turns out to be a camera defect.

I've used my XF305 outdoors a lot over the past month and things still look normal. Knock on wood. Like any camera, I avoid letting the sun get into the VF but I haven't gone out of my way to be extra special careful . . . now I will be. Thanks for the warning.

It sure can. The same glass eyepiece that enlarges the image in the viewfinder can also act as a magnifier for sunlight going in. It can then burn the small monitor inside, like a magnifying glass does to a leaf. I've seen viewfinders with this damage.

panny's are notorious for that..one friend burned his HVX-200 viewfinder and another friend toasted his HPX-170. (we are in AZ so a LOT of outdoor sunny shooting occurs) My hmc-150 has a thick black sock over the viewfinder since I don't use it. (prefer an external monitor)
Panny's were around $250 to replace!

I'd be surprised if it's not mentioned in the camera instruction book, it is with most cameras.

Burned artifacts in viewfinder

Thank you for your comments - but what I can't understand it this happened to TWO cameras in 4 days?? I've been shooting for over 20 years - and I've NEVER had this? The first time, I thought there was something just wrong with the new XF300. But now the second time? I was only outside maybe 2 hours. Either I was shooting (using the rear viewfinder) or walking around - I keep the viewfinder level with the ground - so it's not like the sun is glaring into it! I never just sit the camera down by itself so accidentally the sun can shine in! (That I know of!) I thought maybe this camera was extra extra sensitive or something . . . or would it have been something else I'm doing?

Hi Larry,

Sorry to hear about the problems you're having.

You've probably called B and H already? I'm curious what they (and Canon) have to say. Please keep us updated.

Best,

Could very high humidity be a factor?
I imagine you're protecting against condensation just like preventing the sun from entering the viewfinder since you're an experienced shooter, but it is an odd two events so close together.
I'm planning on getting the XF300 soon, is there any specifically "new technology" about the viewfinder that might make it more vulnerable than past types?

It takes very little time for sun to burn the viewfinder LCD if the angle is right. When shooting outside, I always put a piece of gaff over the viewfinder when it's not in use to prevent such an issue.

The early pro Sony color VF were easily damaged by the sun, it took just a couple of seconds to leave a pink or green blob on the finder. Just walking with the camera and the finder point in the direction of the Sun can do it.

The Sony EX3 manual specifically warns of this well know "sun magnification = damaged viewfinder" risk too - for those that bother to read manuals...but to have it happen twice with 2 separate Canon XF cameras in such a short period of time sounds very strange/worrying????

Re: Burned artifacts in viewfinder!

Just wrecked my viewfinder today with this. I hadn't pointed the camera at the sun or the viewfinder. However I wear glasses and am thinking that maybe my lens reflected sunlight back onto the viewfinder screen.

Does anyone else with this problem wear glasses?
