That is out of control... I have never had any issues with my D300 and or D3. As for my new M8.2 , I love it... No issues with green flare to date. It is weak with low light compared to my Nikons, to state the known, however, I'm fine with the effect and post adjustment. The only issue I have had to date, was two white frames on continues at night, with about 100 frames left (DNG ) on 8 GB SDHC card with a 1/4 battery left. I turn the camera off loaded a new card and battery and set out again with no issues. As a newbie to Leica, I like the difference in effect and mobility Leica offers me. In a short, my 8.2 is a giggle to shoot with and great fun; if I need more I turn to my Nikons.

Thanks, Imants. Very interesting link.

 

from Canon EOS 5D MkII - Black Dot Problem - Bob Atkins Photography ... Pixels in the image area should not be able to generate a signal lower than that of dark pixels. The dark reference pixels are usually on the outside of the array under an opaque mask, so their signal is the lowest possible signal, determined by leakage current and/or noise. ...

That is, the Canon problem _may_ be related to reading the same dark reference pixels as generate the M8 Green Stripe. (Two completely different phenomena obviously, but maybe more closely related than we think.)

 

 

from Canon EOS 5D MkII - Black Dot Problem - Bob Atkins Photography ... While $2700 is a LOT of money for me, those who think it's a fortune for a camera should look at the price of some scientific cameras. In the grand scheme of state-of-the art electronic imaging devices, $2700 isn't going to get you perfection. ...

No, for that you'll need to lay out $8000 for a D3x. :D

Just wanted to say thanks to the guys that posted the images of the green stripe....I'm planning to get an M8.2 next year and am eager to learn everything possible before purchasing.

 

But I've never had a perfect camera. Every camera has some kind of quirk...it's just nice to know what they are ahead of time so there are no surprises.

 

anyway....thanks again for the posts

...As you can see the bright lite is hitting the sensor edge from something like a 45 degree angle. ...

 

It's interesting because I do these shots all the time and this is the first one in 2 years. There have been several thousand shots with these light sources in the frame.

 

Guess it's just that exact spot at the edge....

 

It's absolutely wild that this doesn't infect the rest of the image.

 

Bill, is that your 35 Summilux ASPH?

 

I don't think it's the angle. My example is from a 21, so the light will have been from a wider angle. But in both cases, it resulted from an overexposed source right at the very edge. More likely just the location, I think.

 

As I said above, what you shoot is about as likely to generate the Dreaded Green Stripe as anything could be. It's great that you've gone this long without it. It is clearly a very uncommon occurrence!

Red, I think you've said it perfectly. "It's a giggle to shoot with." I've got a D200 but unless there's something I know I'll need it for, I leave it home and take the M8.

 

Nothing wrong with the Nikon. I'd like to get a D700 sometime, and some better lenses--but the M8 simply catches my fancy. It moves me.

Gentleman--Quirks we've got! But it's a wonderful camera, and you won't be disappointed.

Bill -- you've proved that even shooting into stage lights it's a one in a thousand opportunity to be rewarded with a green stripe, so count yourself lucky! I've only had one in two years. The folks who made it reproducible set up their M8s on a tripod with a 28 or wider lens in a kitchen with little bright spotlights, and shifted the camera angle by a degree or less between shots to get one with a light right at or just beyond the frame edge.

 

Leica has pretty much admitted in communications to this forum and on their website that this is an unfortunate property of that model sensor and they do not plan to fix it in firmware. And I think they even sort of admitted that erroneous black point sensing is the cause. I bet they are testing for it big time with the S-cameras. That's where the learning from the M8 seems to be going.

Hmmm. I just looked at the 5D-2 pics. The black dots look very similar to a problem that Sigma had a few years ago with an early version of their RAW converter for their FOVEON DSLR.

 

Much of it ended up being due to a bug in the software that was generating 'illegal' color values during the debayering process. The highest values would show up as black or grey dots.

 

So, it may just be a software problem and not hardware related; but Canon really should have caught that one. It's pretty obvious. On the other hand if it's the hardware, things are going to get ugly.

As well as my M8 I have a D200, and got a D700 recently. It's a really great camera, no doubt. Superb at high ISO of course, used 3200 at a wedding over the weekend with the new 50 f/1.4 AFS.

 

Horses for courses though, much of the time I prefer the M8 - tonight I'm going to a social event, low light but will take the M8 + 28 and 75 Summicrons.

first the AF issues of the 1ds mkiii

 

and now the mysetrious 'Black dot' issue of the 5d mkii

which is all over the forums and appears to be quite a BIG problem

(see example below !)

 

who says only the M8 has problems/foibles:

The 5D MKII and the 1D MKIII aren't the only cameras that people are complaining about on the Canon forums. I have a Canon 50D and it's getting its fair share of grief as well. :D

 

Every morning I spend way too much time on various forums. (BMW, Porsche, Ducati, Leica, Canon) The one thing that ALL the forums have in common is that people bitch about anything and everything that's new and/or different. :rolleyes: (I also go to a Martin guitar forum but people don't complain there. It's sort of a mutual admiration society. :p )

 

Before the Internet if a camera/car/motorcycle had a problem we just learned to live with it. Now everything has to be perfect. Maybe that's good. I don't know.

Howard and Scott, yup, I'm lucky. I shoot a lot of these kinds of shots -- tho I try to get a better image than this one (disregarding the stripe), can't imagine what I was seeing when I hit the shutter!

 

It was surprising to see the stripe. It surely is a rare thing. And, it's neat that the rest of the image is still ok.

 

Ansel, watch out! Green stripes are in. I can see it now: the new book, "Green stripes with swing and tilt actions on the view camera."

As far as the green stripe goes, some people have luck and some don't. I've seen it on location exactly twice in 50K shots or so... I know Jeff Ascough saw it twice in two weddings (or was it three times in three weddings) and that nixed the M8 for his use.

 

Green stripes running through a bride's head is not exactly confidence inducing; fortunately I haven't had the problem. I think Jeff shoots in locations with more chandeliers, which you can image would wreak havoc with reportage...

I've been shooting my 1D Mark IIn since it came out, feel NO need to "upgrade" to a Mark III of anything. Full frame is nice, but doesn't excite me. I went the other direction...

 

In August I bought an Ikon, and in October an M8. I haven't shot with the Canon kit much since August.

 

I'm very happy with where my gear is, regardless of what the latest is. I'm enjoying my "regression" far more. ;)

I just bought my first M8, I just joined this forum, but god do I hope that I don't get as obsessive as some forum members here, glowing happily over the bad quality of competitors cameras seems a bit childish, to say the least.

Och, weell, misery loves company, y'know....;)

To set things right Canon might offer a EUR 2.000.- upgrade for their loyal customers à la Leica...

 

But will they offer the early 5D II adopters an apology letter and 30% off one of the Canon L lenses? The Eur 2,000 upgrade is more likely :)
