M8 - Green Smudge

[ho_co]

Oh, I see what you are saying - don't take an image with a (brighter) light at the edge

 

Not quite so simple, but that's the direction.

 

Just be aware that the problem can occur whenever a greatly overexposed bright area is just a couple pixels outside the image area. It happens occasionally, and it's always a disappointment when it happens. One way to counteract it is to make several shots one after the other when handholding. That way, you'll often have one or two where the problem doesn't occur.

 

It always extends from one of the short sides of the frame to the center-line of the sensor.

 

The Green Stripe was discovered shortly after the M8's introduction, and was eliminated by the new sensor in the M9.

It sort of dampens one's potential enthousiasm for an M8. 8.2. 9?

[Nicoleica]

Thanks guys - as I indicated I need to modify my style - the M8 is still very new to me

 

Just out of interest, do you have a silver UV/IR filter (Or any other filter with a silver frame.) on this lens? It's remotely possible that a bright reflection highlight from that could be causing the streak.

Thanks Nicole for your interest

 

The lens is a Zeiss ZM 28mm f2.8, fitted with the correct Zeiss Hood

The filter is a black Leica E46 UV/IR 13411 - (The filter threads inside the filter - could be (remotely) said to be "silver"), but that is all I can see.

The lens is only a few months old and I have used it on my EP-1 and G1

I bought the 28mm lens as I had the intention of buying an M8 and wanted an (effective), 35mm FOV.

(I plan to move to an M9 next year if I am happy with the M8)

 

I tend to use scale focusing - I am sure that the f value was f8 and ISO 160 - the EXIF data indicates a shutter speed of 1/250th - but the lens is not coded, I sometimes find that even the f value is not accurately reflected in the EXIF data

 

I'll just accept it as one of those (happy) quirks of Leica digital photography - no real worries on my part - the M8 is just "different" from my D300

 

(I need to clean the sensor - but that's another story!)

 

Best wishes

Thanks Howard - I see what you mean

 

Quite novel - in fact I'm now quite proud of my "green smudge" - I won't call it a "green streak" - mine seems the best of the lot!!

Not really. As far as the M9 is concerned I don't believe this minor glitch is in the M9.

 

If you haven't already bought a M8/.2 or 9 I doubt you ever will or any digital M that may come out. I see posts like this all the time and they always come from people that look on the M digitals as the glass half empty and they will never see it as half full. Let alone filled to the brim.

And you never will except by dumb luck. No matter whether the lens is a Leica lens coded or not or any other makers lens coded or not. The lens is not electronically couple to the camera. So the camera never really knows what f/stop you are using. The f/stop displayed in viewing/editing programs is just a guesstimate, an approximation.

yes - see what you mean

 

just taken 11 shots at f8 - (outside)

 

EXIF shows, 7 @ f8, 1 @ f9.5 and 3 @ f6.7

 

and there's me thinking it's because the lens is not coded

 

Still it is better than using MF (adapted) lenses on my M43 where no value is shown in the EXIF

I don't quite get it. Assuming I would want to acquire a "mint" M8, with the appropriate "upgrades", and a suitable lens (" 'Cron"; or something); would I still need to avoid fierce light sources in the frame I would like to compose?

 

Just a question.

 

Sorry. Wrong quote. You get what I mean.

It’s light sources slightly outside the frame that you want to avoid.

 

But then you could get an M9 that is free of this issue. Why worry over the quirks of a camera that is out of production and that you don’t own?

I would think that the "green smudge" would be the least of your worries if you acquired a M8 - as from what I (assume) it (may) be your first RF camera, (but maybe not?)

 

How are your eyes, do you wear glasses, are you happy with manual focus, what kind of subjects do you shoot, have you a preference for telephoto lens - how big it your bank balance, if you want to buy Leica lens, (although good Nikkor glass is expensive as well as being physically big)

 

Also, I am sure that you are aware, but I may as well mention it, that if you go over to the RF Forum all the "characteristics" of the M8 are discussed since the cam was released - there are three full pages of "reported problems" and any new user is advised to consider these objectively before any purchase, I did.

 

Good luck with your "considerations"

 

(have a go at the M9 "red edge question" if you want to continue along the colour theme)

Your concern for my wellbeing is much appreciated. I have reasonably good eyesight, usually don't wear glasses (- .75, - 1.25 or something), am reasonably fit physically, in good mental health (I think...; I'm certainly not the complaining type), use primes only (24, 35, 50 and 85) and the state of my bank balance is none of your business.

The "red edge" problem certainly makes for a good read; thanks for pointing that out. If I understand you correctly the M8 (and M8.2?) should not be considered, but the M9 should? OK. I prefer full frame anyway.

[paragon]

No I did not say don't consider the M8 - after reading all the info that I could I went ahead and bought one.

 

At the moment I do not feel like spending £5k on an M9 and (maybe) an upgrade from my D300 to a D700 would happen before I considered an M9 purchase - although it is rumoured that the D700 will be replaced soon

 

I do however, feel, that because of the (larger) DSLR size, my M8, EP-1, G1, and S95 will get used more than the D300 in the next few (winter) months as I am more likely to take them with me.

 

Although I still have a M6 and M3 I wanted to try a RF Digital and considered a good used M8, at under £1,500, not a bad way to proceed.

 

I am completely open minded about most things, (inc, cameras), and prefer to appreciate and enjoy the merits of each even if sometimes your (my) expectations are not met.

Have not seen it been produced with a M9, yet. Anyone.

 

And else; only once with me, in may thousands of images. I sleep well:rolleyes:

Red, Green and now Blue!

You may have a 'special' camera. I tried to duplicate your results by shooting directly into the sun, but did not find any green streak or smudge, just lots of green leaves...

Bert, it's hard to duplicate but well documented. See Leica's M8 FAQ.

 

If you want to try to generate it, there are a lot of threads on the topic. Very bright source must be just barely (a pixel or two) outside frame; it may obviously also hang over into the frame.

 

Easiest way to look for it is to use a tripod with swivel head and a bare bulb.

 

 

It definitely doesn't happen with M9, only with M8 variants.

[epand56]

Never had a green stripe in thousands of actuations on my M8. Ok, it may happen, so what? I'm sue all those huge Nikons and Canons have their own quirks, the need of a van to take them around, for example...

Hallo,
