Glad to hear that. Are all your corners equaly sharp to the eye now?

->

yep, whole view is now equal sharp, i need to shoot more pictures to verify that every scene gives me same results, but so far after service printed pictures are SUPER sharp, this is what i was expecting from this camera.

Bad luck that i had focus and sharpness problems with my camera and my lenses.

Happy user again. After all 5D is mass production line product, so errors happens.

Got the camera and lenses from service.

At the service they found AF focus problem and they fix it, also my lenses had recalibrated because of miss balanced sharpness. Have to say that i got competent service and i am happy for that.

Sorry if i my explanation was dramatic, it did not meant to be dramatic, probably reason for this is my bad Eglish delivery.

And why i kept camera two moths, im not PRO photographer, when you have bought equipment that cost over 2k ?, you probably in first place doubt that your skills are not good and you doing something wrong. Before i take test pictures i simply doubt my skills every time when i was looking bad quality picture.

Perhaps your film (sensor) plane isn't true.

I think that my sensor is totally broken and it has been that from factory, if it is problem or is it feature? I think im not alone with this problem when viewing pictures taken by 5D there is pics that has same fault left side of picture is not sharp as right side.

This discussion is from old thread which is dead, so started new one.

Text below is copied from older thread.

Hi, i switched my camera to 5D two months ago. Unreal problems since then.

Focusing errors and other weird problems , left bottom corner is sharpest but

DOF in the left corner is worse. Right bottom corner is near sharp as left

bottom corner but not as good that left bottom also saturation problems on right

bottom corner, DOF in right bottom corner is best. Centre of image is sharp but

not equally when compared to left bottom corner. Upper right corner is very

soft, left upper corner is soft but not so soft that right upper corner is. Also

focusing point is not always sharp, sharpest part of picture varied. Camera is

in service. Hope that they can do something with it or i neet to shoot whit my

ixus 400 which gives me better pictures at the moment.

Were you using a crop camera previously?

-> yes 30D. I know that corners in full frame camera is softer than eg 1.6x crop

camera but my problem is far from that. Test pic that i take with camera was

following 5 A4 sheet's printed out 8 to 72 point diagram which was full zero's

and x marks like xoxoxoxoxoxoxoxox increased by two. So that first line has

8-point letters, second line 10-point letters etc... one a4 paper in middle and

rest of a4 papers so that they was connected to middle paper with their corners.

Focused camera to paper that was in middle from 3m, camera was in tripod and

self-timer was in use. Test result

The paper that was in middle was readable to 12-point letters from picture. Left

bottom corner 8 point letters was VERY sharp. Right bottom corner 8-point letter

was readable but soft. Left upper corner 16-point letters was soft 18-point

letters was clear. Right upper corner 16-18 point letter was unsharp 20-point

letter was sharp. Papers was connected to wall with black tape, in right bottom

corner tape was in picture blue. Tested with 3 different lenses which all are

L-series, every time some result.

->

In landscape picture which was focused to 10m errors appears like following,

left site picture was very soft to the half of picture, left bottom corner was

sharpest on picture which should be in full frame camera worst. DOF in left site

picture was inferior than right side?. All picture was taken with raw, even if i

worked half hour with photoshop i could not get pictures out that was sharp.

->

One clarification, distance varied depending focal lenght of my lenses 17-40,

70-200 and 50mm 1.8M1 test pictures what i take was taken so that the five A4

papers was in picture wholly and when i say that some corner was not sharp it

stand whole row of A4 paper. So my pictures had 10% area in left bottom corner

which sharp. Rest of pic is mess. Have to say that im not satisfied Canon 5D

user. When you are buying camera that cost honey you certainly expect to get

quality on your hands and not camera that is comparable to market cameras.

->

Was it when the lens was wide open and improving as you stopped down?

: Tested with 4/5.6/7.1/8 and 11 no matter to final result.

Was it worst for ultra wide and better for telephoto?

: as i mention upper results where little better whit telephoto lenses, but

still very poor result.

Can you put up some 100% crops so we can see what you are talking about.

: attempt to do that yesterday but site has 100k size limit, and image must be

viewed with full size to see errors correctly. I can post image if someone wants.

Was the problem in the same corner(s) for all your lenses or does it depend on the lens?

: Problems was all the time same places, when used smaller focal lenght lenses problems was worse.

The paper that was in middle was so sharp that i was capable to read 12-point letters from picture.
