Could you help me please, or if anybody have the same phenomena.

I’ve bought my NEX-5 just after its appearance on the market firstly with the conception of using it with (adaptered) manual Voigtlander/Zeiss etc. lenses as soon as posible.

So, I’ve bought an adapter Leica-E and everything’s fine except one very strange phenomena:

When I shoot in RAW/ARW format with the adapted manual lens on, and then I enlarge/zoom in the image in the camera, it mostly result a ”greenish/like expired film” or sometimes a totally „meaningless bw” image. Just if enlarging it. With the kit lens the problem does not appear or in JPEG format neither.

Have anybody the same problem? What should it be and why? Firmware/software problem?
Any unique fault with my camera? Thank you.
 
Sounds like a problem with the software you are using to view/edit the raw files.
Do you get this problem with the Sony lens that came with the camera?

I am sorry if I wasn't totally clear (my English...). So, I have no problems with teh produced images.

The problem is only with enlarging the ARW image shooted with the manual lenses in the camera display. Just in the camera display when I playback them, the enlarged images appear totally badly as I mentioned. With the Sony lenses (both shooted ARW and JPG) are totelly perfect from the beginning, also JPGs shooted with the adaptered lenses. Enigmatic for me...
 
No problem with your English, I didn't read your post properly, sorry.

It does sound very odd. I suspect it's not a problem only with your camera.
I don't have access to my adapted lens right now, so I can't test it myself.
Hopefully someone will.

Thank you very much for your inmediate reaction. So I hope that somebody coluld check it and if it's a global phenomena Sony will find out the solution (firmware?)
 
That image seems to have the appearance of an un-demosaicked RAW file. Normally the cameras LCD image is constructed from the embedded Jpeg which is present in all RAW file data, instead of enlarging the Jpeg file the camera appears to be trying to display the RAW file.

At one time cameras could not display any image if RAW files were used & they could only be seen in computer imaging programs when the RAW files were downloaded into the computer.

Have you got installed or downloaded the latest firmware update ?

Yes, I updated the firmware for the body (2.0) so I have it already. For the lens, I still have the version 0.0. Maybe I should update it either?...This is my suspicion right now...
By the way, thank you for the details about the camera image process.
So is it the lens firmware problem...?
 
I have shot numerous shots with the Leica 40/2 lens with adapter and there is no issue for me in zooming in on the image in camera or externally using Bibble 5 Pro. Right now it is the only manual lens I won so I can't verify how other lenses might work. Unless it is somehow interpreting the lens to be something it isn't I don't see how the camera's processor could process it differently for one lens versus another.

Thanks for the information. And which firmware do you have for the body/lens?
 
I duplicated this...just took my lens off the camera, set it to Raw ONLY (no jpg). The images look "normal" on playback (with lens off, generally uniform color and shading across the image plane). But when I hit the enlarge button, odd things happen. Sometimes I get a large color shift (to deep blue or green), sometimes a solarized B&W mess of an image.

And what the image does during an enlarge can change each time you look at the same image. So the same image can look green one time, a while later when you go back it can be B&W, the next time blue...no real pattern that I can tell.

With the kit lens on (even when defocused to look like the lens off pictures), I can't get it to mess up. So it has to do with a non reporting lens (or no lens) being on. It does not effect the raw image at all (opens fine in IDC) and the non enlarged preview is fine. Just the enlarged preview with RAW only and a non reporting lens.

This won't affect me at all (for now), so it's not a big deal for me. But I can see how it may be irritating if you only shoot RAW and use manual lenses.

Here is one example image. I took pics of the back LCD with my Canon. Remember, these are all the exact same RAW file in the camera!!!

Here's what it looks like in the non enlarged preview:



Here it is enlarged (but zoomed as wide as possible) with the B&W solarized pattern:



And here is the same image with the green hue:

OK, I can reproduce it too when shooting raw only. It actually looks kind of cool. Anyway, it doesn't happen with Raw + Jpg, only when shooting RAW ONLY AND using a non-Sony lens (I don't know if this happens with Alpha lenses on Alpha adapter.

Thanks for all, so I am more staid now.

For the time I will use RAW+JPEG and than let's see if there will be any solution later if it's possible...
It's just a little awkwardeness really for now.
 
Doesn't anyone find this situation rather disturbing ? It strongly suggests either that this is deliberate or a serious QC mistake which has gone totally unnoticed !

I have to assume that it is not an unsolvable error in the original prototype software but something which somehow crept in during the production stages. Why on earth was this not noticed & corrected in the QC checking on the production line ? Is it that no cameras are checked with the adaptor & manual lens attached - if so this is a serious oversight & something which should be corrected immediately.

We are frequently told that no one should buy a camera without satisfying themselves first that it does what they want it to do & so ,believing this to be true, no one should buy the NEX automatically thinking that this issue will be addressed in a firmware update until Sony make a public announcement that this will happen .

I remember the unofficial promises about a firmware update for the A900 which were never translated into action.

I picked up this error from a Japanese user who reported the same problem.

The root of the problem is in using a lens other than E-mount or A-mount (via LA-EA1 adapter), and shooting in RAW with DRO mode enabled.

If you disable DRO, the playback problem goes away.

It appears that Sony simply has a bug in decoding RAW files that are shot in DRO mode with 3rd party lenses. Hopefully they can sort it out in the next firmware update.
 
Yes that does provide some clarification but surely DRO has never worked in-camera when using RAW so how come this error slipped in ? Who on earth tests these cameras , is there any responsible management in the factory ?

I can only duplicate the "polarized" play back phenomenon once. I went back and changed the setting to RAW+jpg and took a second image. The playback was normal, including the first image. Then I set it to RAW only and shot a third image. The playback of all three images were fine.

I am using the updated firmware, manual lens via an adapter.

Shoot in RAW with DRO enabled. If you have review enabled, you can click "Enlarge" at that time, and the display error should occur.

I just did a quick test and have found that if I take one shot RAW+DRO (reproducing the error), then change the settings to disable DRO and take another shot RAW without DRO (no error), then at playback both images will enlarge correctly.
 
This seems to suggest that software processing 'pointers' are not reset every time before use & are conditioned by the initial starting sequence.

Please, please don't let anyone suggest that this is something which is just a little quirk which can be lived with. :)

Ooops, it's extremely strange...really, if I disable/switch off DRO (in my case i've just let it there without any reason...) the problem seems disappearing...well, all of this is just a detail but also a kind of failure maybe...
