Yesterday I was taking photos using Live View engaged and noticed a few shots with an aperture of less than F5.6 vignetting on one side. So today I did some testing using various lens and various apertures, findings were somewhat interesting.

When taking a photo with a Canon EF lens ( 180mm Macro, 135 SF, 85 L and 50 1.0L) this glitch did not appear whether live view engaged or not. Photos were fine both ways.

But with an Alternate lens (Angenieux 180mm, Nikon 135 DC, and Leica 180mm) on and aperture set to less than 5.6 and live view engaged vignetting appeared badly on one side. But if I disengaged live view before taking the shot, the picture turned out fine. If aperture was F5.6 or higher no vignetting..

See samples below right shot is with Live View engaged. No post processing done on the shots except resizing.

I shoot live view all the time, never have seen this? wierd? are they RAW or jpg?

Raw. I thought it might be an adapter issue but though not shown above th Leica also did the samething. I at least have the work around by turning off live view after focusing and then shoot. And I agree wierd since it only does it with Alts.

Call canon and see what they say, most likely nothing as your using an adapter? I really wish I could help as I love shooting with live view, it kicks ass haha

It looks like the mirror is blocking part of the light path to me.

I've seen the same thing as well! Thought it was in my head.

this is wierd. It can't be the mirror, since the mirror is up during liveview shooting. I had the reverse problem, where when I shot at infinity with the rokkor w/o liveview, the mirror would block the light path, but there was no problem otherwise.

Does this only happen at infinity? Try at shorter distances...

Looks like a timing or reset issue between one of the shutter curtains and live view. No idea why it'd only affect certain lenses though!

Does this happen in the landscape orientation, too? Maybe the mirror is not fully locked up. Does this go away if you turn the camera upside down? I didn't see this on 1Ds3.

Hmm. I read "side" and thought landscape, but if indeed they're only resized then of course these are portraits and the shutter's out as a cause. I wonder if looking into the mirror box and rotating the camera with live view engaged and no lens attached would be at all interesting...

I first noticed on Saturday in portrait mode but only on 1 camera. Distance was about 20 feet. The shots I took Sunday as seen above was deliberately done in portrait mode to see if it reoccurred and if it occurred on all bodies.

In landscape mode I didn't notice it on Saturday but it was possible it was there as I was shooting into snow so the bottom of a few shots had a slight blue tinge to it.

I'll will likely try a few shots again this weekend assuming weather cooperates using some other alternates to see if it happens to them too. And try different orientations.

Both Saturday and Sunday they were shot tripod mounted.

Another thought I had was the position of the sun but Saturday shots were in two different directions and Sunday an entirely different direction and then it clouded up shots above were after clouding up.

I basically view this now as a glitch and not a big issue for myself since my work around is focus with live view turn off live view for alts then shoot. Or shoot at aperture setting of F5.6 though F32. With Canon lenses just shoot away no issue.

I'll let you know what I find next tiime I shoot. Though I'll have 1 less 5d MKII to test with. I have sent one off to Lifepixel for conversion to full spectrum.

I've seen this using Liveview with my 40D mounted vertically on a 4x5 view camera when shifted.

My solution: turn off LV before taking the shot, lol.

I can't reproduce this, for what it's worth.

I have this same problem, and have gotten a few shots ruined due to it. Sometimes it is quite severe. I thought it was just me...

I did not see this with the 40D. I have been thinking about a 5DII just for the LV. This is a deal breaker for me.

Always in portrait orientation, or in landscape as well? How about when the camera is inverted in landscape orientation - is the problem worse?

What's the camera setting? shutter speed?

I couldn't reproduce the problem even with the camera in upside down position

I have noticed differences in using LiveView with flash. I have a 14EX ring flash connected to the Leica APO 100mm macro. When I use the viewfinder, the shots are ok but when I use live view, it is blurry, like motion blur. Anyone has the same experience? I will play with it some more to fiigure out what is going on.

Turns out with LiveView and Flash is used, the mirror comes back down (I believe it is for ETTL metering?) and then goes back up again before it takes the shot. I think I started to move the camera once I heard the first shutter movement hence I got motion blur. I have to remember that next time.

BTW, I didn't get any vignetting as OP did.

Went out today and was able to reproduce including shooting upside dwon. Used the Angeneiuex 180, Leica 180, Canon 180 Macro with same results. I also used the coastal Optics 60mm and Nikon 28mm lens Intersetingly enough the Nikon did not produce this. It occurs only on the opposite side of the mirror, not as noticable when camera in landscape positioning but there none the less. Anyways I see this as an inconvience glitch, I'll just turn off Live View after focusing for non Canon lens. Todays shots were near infinity focusing.

i believe that when you are using Live You should turn Off the miror lock up option !

Using a Mirex blad and a Oly 35 PC i don't have this problem... but i've find some strange flare once... maybe lihgt coming from the eye piece ?

You could try shining a penlight into the viewfinder while taking a long exposure to confirm this possibility, but it shouldn't happen. The mirror's position during exposure should effectively block off this light path. (Though extraneous light entering the viewfinder before the exposure can certainly affect your metering!)

Surprisingly quiet discussion since if this is common 5DmkII problem this basically means that 5DmkII is not usable with alternative lenses (depends on shooting style but I shoot 99% with live view). Is burningheat the only person suffering from this?

I'm considering 5DmkII but secondhand 1DsmkIII start to seem interesting choice if there is even slight risk of this bug in 5DmkII. 2nd hand 1DsmkIII only about 2k more and has better autofocus / custom functions / viewfinder for the situations when I'm not using alternative lenses. Only bad thing about 1D series cameras is the size and weight. Luckily they still don't have 5DmkII in Finnish stores...

I think it is only in portrait mode or similar "off horisontal" shooting. Havent seen it in a while though. The problem just appears every now and then for me.
