peter_jarmuda Posted June 25, 2007 Share Posted June 25, 2007 I recently bought brand new 5D and after 2700 pictures I get this black frame around the image. This happened for about 9 consecutive shoots and then it stopped on its own. Schould I be concerned about it? I keept on schooting that wedding and there were no more blurbs like that. On this image I used 24-105L/Is lens Thanks for your help. Peter Jarmuda<div></div> Link to comment Share on other sites More sharing options...
ryanjoseph Posted June 25, 2007 Share Posted June 25, 2007 Thats some pretty bizarre vignetting. I have never seen anything like it. Have you tried the camera with diffrent lenses? I know I am probably wrong but I would try that first before I send the camera in under warranty. Either way, something is definetly wrong.

peter_jarmuda Posted June 25, 2007 Author Share Posted June 25, 2007 Like I said I got about 9 consecutive shoots like that and then it was all fine. Link to comment Share on other sites More sharing options...
jake_holt Posted June 25, 2007 Share Posted June 25, 2007 You may have just knocked the lens hood crooked - I did this once with my 17-40 and got almost the exact same results. Thought I had a busted shutter at first! See if you can re-create it by turning the lens hood out of the locked position. Link to comment Share on other sites More sharing options...
ryanjoseph Posted June 25, 2007 Share Posted June 25, 2007 That's a good suggestion James, this has never occured to me because I use a 1.6x crop camera body. Link to comment Share on other sites More sharing options...

wilbur_wong Posted June 25, 2007 Share Posted June 25, 2007 I suspect that the tulip shaped lens shade was in use, and it was not fully screwed on. Try a sample shot with the lens shape slightly off at the 24 mm end and see if you can duplicate the vignetting. Link to comment Share on other sites More sharing options...
peter_jarmuda Posted June 25, 2007 Author Share Posted June 25, 2007 Jake I hope that was it. I'll try to recreate that tommorow, and in the meantime I might get a better slep tonight Link to comment Share on other sites More sharing options...
fourfa Posted June 25, 2007 Share Posted June 25, 2007 it's the lens hood. Link to comment Share on other sites More sharing options...
PuppyDigs Posted June 25, 2007 Share Posted June 25, 2007 Been there with my 5D and 24-105. Hood needs to be installed correctly. Sometimes the light’s all shining on me. Other times I can barely see. - Robert Hunter Link to comment Share on other sites More sharing options...
greg lockrey Posted June 25, 2007 Share Posted June 25, 2007 It's broken! Link to comment Share on other sites More sharing options...
peterlyons Posted June 26, 2007 Share Posted June 26, 2007 Definitely the lens hood! I get this too often. I'm starting to tape the hood in place using gaffers tape. Dials and buttons too. I bounce around on a boat all day (no complaints!) so hoods, buttons, dials, are constantly getting whacked. Then I notice the problem 50, 100, 200 shots later. I'm starting to wise up and get stuff taped down. Good luck and have fun! Link to comment Share on other sites More sharing options...
dogbert Posted June 26, 2007 Share Posted June 26, 2007 It looks to me like something is not right. Wedding shots should not look like that. Link to comment Share on other sites More sharing options...
mvw photo Posted June 26, 2007 Share Posted June 26, 2007 Lens hood crooked. I get it too sometimes. Exactly the same. So, no worries, all is fine Michael Link to comment Share on other sites More sharing options...
pjmeade Posted June 26, 2007 Share Posted June 26, 2007 That's the lens hood, no doubt. I've had that myself when I hadn't put it on correctly. Link to comment Share on other sites More sharing options...
savagesax Posted June 26, 2007 Share Posted June 26, 2007 Agreed, the hood gets bumped sometimes. Make sure it is on right. Link to comment Share on other sites More sharing options...
j_smith6 Posted June 26, 2007 Share Posted June 26, 2007 I think that the sensor is broken. So many dead pixels in a new camera... :) Link to comment Share on other sites More sharing options...
scott sanford Posted June 26, 2007 Share Posted June 26, 2007 Yes, it is definitely broken. However, I'd be willing to take the 5d for half of what you paid if you want to unload it. .....No doubt, a lens hood issue from this vantage point.

wilbur_wong Posted June 26, 2007 Share Posted June 26, 2007 On second thought, the lens hood IS right, it is the camera that is crooked. . . . (sorry, couldn't resist) Link to comment Share on other sites More sharing options...
joe_oconnor3 Posted June 26, 2007 Share Posted June 26, 2007 Hi, I've had a 5D for a good while now. I experienced the same kind of fear when the camera was new. Then it occurred to me that all of the reviews state you need a really good (no great) lens. I found the one sure way to combat the vignetting is to stop down the aperture at least one or two stops from maximum wide-open. If you need to open the aperture all the way use Camera Raw's vignetting control to de-vignette the photo. Enjoy your 5D I know I have.

mark u Posted June 26, 2007 Share Posted June 26, 2007 Stopping down is a cure for vignetting within the lens (due to the lens barrel obstructing the fully open aperture or due to fourth power cos law fall off toward the image corners): however it will merely emphasize a skew lenshood, bringing it into sharper focus.

HarryBaker Posted June 26, 2007 Share Posted June 26, 2007 Definitely the lens hood, Peter. I got my new 5D just a week ago so have taken fewer than 100 pictures. Then I had exactly, but exactly the same thing as you, especially on the widest end of my 24-105. The hood which clicks into place tends to rotate slightly when you put it back in your bag and the rest..... Link to comment Share on other sites More sharing options...
arlen_c._elkins Posted June 26, 2007 Share Posted June 26, 2007 You also need to correct for that black gadget bag showing up on the path at the end of the bridge - need to reposition it Behind the lens for best results and less cloning in Photoshop!

roger_smith4 Posted June 26, 2007 Share Posted June 26, 2007 You might try different lens hoods to get the right darkening effect. Link to comment Share on other sites More sharing options...
PuppyDigs Posted June 27, 2007 Share Posted June 27, 2007 Hoya makes a nice smooth vignetting filter. Sometimes the light’s all shining on me. Other times I can barely see. - Robert Hunter Link to comment Share on other sites More sharing options...
