I've been noticing the problem at least 3 or 4 shots a week. Since i've got my Canon 500 F4 IS i think (not had it all that long).

Its a strange dark halo around certain edges that could almost seem like a sharpening halo if it wasn't appearing on completely unprocessed shots.

Example of it... completely unsharpened/unaltered from raw apart from the exposure compensation turned up a little to show it more. Shows up like this in the 100% view of DPP and Rawshooter.

You can see it to the right of the curve of the wing and to the right of the beak too.

Again here.

Both images are 100% crops.

There are some blown highlights along the leading edges of the wings (though nothing that highlight recovery can't get back in raw processing) and just a tiny line of pixels blown on the red channel along the beak in the 2nd one, again nothing that processing can't fix.

Its causing me a lot of hassle... i have to spend ages and ages going around the outline of the bird with a soften brush just to not have a big thick black halo around it once its reduced to web size.

I didn't have the hood on the 500 F4 but then i was standing in complete shadow with the sun also behind and to the right of me.
No filters were used.

Has anyone seen anything like this?
I need to get this sorted before the canon warranty goes out of date on my 1d about a month from now
 
Image stabilizer wasn't on.
I can't understand why it'd be a dark ghost when the thing it's ghosting is a really bright edge either
 
does it only happen with the 500mm lens and ther 1d?

do you have a different camera you can use and check for the problem?
 
I've only seen it on moving so far but its definitely the high contrast line with a dark background doing it.
I need to try and set up a test at home with something stationary but its a bit of a pain with the minimum focussing distance and setting up the conditions :bang:
 
i've tried it with my 30D and it doesn't do the black line ghost like that but it does seem to do some sort of ghosting still.
This is looking like sending off my big lens and the 1d for a service the more i look at it :(
 
Thanks Ian. I think i'll have another go with the 30D on it tomorrow and see if i can reproduce it.
The problem is my 30D's AF is terrible for getting the type of photos i've pasted above in focus, so its hard to tell if its ghosting or just slightly out of focus:lol::bonk:

I've just seen my 1D is out of warranty about the 25th of this month so i better get a move on
 
I've run a test indoors with a stationary object and 2 flashes on it with a dark room behind it.

Basically the 1D produces the effect with my 500mm and my 100-400

While the 30D is clean as a whistle.

Back to canon with the 1D then.

I guess i'm lucky as the warranty expires in just a couple weeks.
 
Just packed up and sent off my 1D :(

Felt like sending off a loved one :lol:
 
(((hugs))) I'm sure it will all be OK :) You'll have it back in no time right as rain.
