R-D1 number 4 letting me down, uhhhh....

[atufte1@mac.com]

Hello again

I thought and hoped everything was good with this R-D1 (nr.4), but once
again i've got a sample with some sort of disease, take a look at this...

I'm about to give up on Epson, and collect a refund
on this camera, but if i have too it will be a sad, sad day
because i really love this camera....uhhhh, what would
you guys do in my case...?

Best Regards

Hi Alexander,

Looking at the first few examples 🙂

Not too sure what the disease is unless you mean the grain. The odd blobs look like lens flare that you'd get with most lenses shooting at bright points of light. This will happen exactly the same on film, although would be slightly less exagerated by the larger image ares (full frame 'analog sensor 🙁 ) What lens are you using?

Alexander,

Man, that's really strange... odd that there are different numbers of "little green men" in different pictures and in different locations in the frame. Are you sure that this is not related to the lens you used? Is it consistent with different lenses? Looks like some kind of lens flare. What about daylight pictures... any greenies there? (If not, then I'd wager that the problem is not with the sensor, but is indeed a function of lens flare.)

 

[simonclivehughe]

On second look, you can see that the greenies mirror the light sources in the image (check out #147 for the clearest example of this. This simply has to lens flare.

I use a Leica Summicron 50/2 (Type 4/the new one)
And i've used a lot of dslr's like the D2x/1DsMKII/D70, etc
for shots like this hundreds of times and have never got'n
this kind of flare, of course one or to flares from time to time
but never from "every lightsource in the picture" and in every
frame, i can not use any of them without massive retusching..
(Not that im going to use any of this images...but either way, this
is way off, and should not appear as aggressive as this...)
I'm also lucky for having two R-D1's at the moment because i still
got the previous camera and this one do NOT have this problem in
the same degree with the same lens...?

 

[simonclivehughe]

If you look at the sensor itself, do you see anything different than the sensor of your other R-D1? I can't think of anything else in the light path that could affect it this way.

Look's identical...?

 

[simonclivehughe]

I guess the only other questions I would have is do you see dissimilar results from the same lens under exactly the same conditions? In other words, could something have happened to the lens between using on your original body to these pictures on the new one? Does it have a dirty rear element etc? Can you do a controlled side-by-side test to see the results from both bodies?

Sorry Alexander, if that isn't the case, I'm out of ideas, maybe you'll get more responses from others that will help you diagnose this. Good luck!

From my experience the current cron 50 (no tab but built in sliding hood) is very good at reducing lens flare (like most recent Leica glass). I wonder if it's the anti alias filter over the sensor that is maiking the flare more of a problem or even a dirty sensor. Either way the point light sources don't have the green halo that the corresponding points do. An odd problem this one. Sorry I'm out of ideas for now. I'm with Simon on this puzzle.

Oh just an off the wall thought, did you have a filter attached to the lens? Maybe this could be the problem, that would certainly explain the halo from light bounce off the front element to the filter.

I hope we manage to resolve this rather interesting puzzle.

Thats a really good question. I've never seen a lens of any kind perform that badly, but I've seen cheap filters cause a lot of problems with flare.

The sensor will record what hits it, and its not going to cause what we see here. My guess is that the problem is optical. Do you have other lenses, or a film body you can try under these conditions to replicate/rule out?

Hmmm, i don't remember if i used the filter i use now with my other R-D1,
but it's certanly something i will give a try, maybe this is the problem..?
I give it a go tomorrow, now it's WAY past my bedtime so thanks for all the
feedback and have a pleasant sleep, ill post my findings as soon as i get the
time...

And again thanks...

It's very, very likely to be the filter.

Sean

 

[aizan]

yup, it's the filter. haven't you seen this before in film?

 

[saxshooter]

You are shooting into direct light sources and I would say you are getting reflections from the filter in front of the lens. Try doing the same without the filter.

I often shoot into light sources (crouching down, shooting up to a person speaking at a podium with lights above pointing down at him) and used to get loads of flare on my D-SLR. I took the UV filters off and voila, the problem was gone.

 

[Fred]

Puzzle solved.

I've seen a similar flare problem caused when a filter was partially misted up in the cold. Star trails come out very odd indeed.

Have fun using RD-1 number 4. Look forward to seeing some gallery posts.

Alexander,

To echo further the posts by Sean, Aizan, Saxshooter and Fred (and without meaning to seem as though I like to keep good company with the majority 😉) I would definitely recommend that you experiment further with and without the filter.

Try different filters if possible, exposing them to variously lit environments.

Aside from the fact that this might even be fun to do 😉 it should at least reassure you that your R-D1 is not at fault in this way.

p.s. I admire your endurance on the Epson R-D1 forum i.e. the official site forum which, save for one post, is miserably attended to by Epson themselves...

That is lens flare.

You are ruining it for everyone else by sending back perfectly good cameras. Please get rid of your R-D1 if you don't understand anything about optics. You'll be doing yourself and everyone who has legitimate problems with their R-D1 a huge favor.

Albeit that you are correct - your tone of response is way overbearing. Perhaps you should consider a "tutorial" approach as opposed to a "disciplinarian"?

Assistance goes much further to advacing understanding than simply scolding. :angel:

I disagree.
Typically filters to me.
Remove filters and i bet you won't see those ghost images any more.
Best,

I think everyone was doing a good job helping the guy w/ the problem. He had legitimate issues with the other Epsons, and wasn't too far off thinking yet another had issues.

Your reply is rude and pointless. We are not a dpreview type of forum. If you looking to fight, find it there. Believe it or not, we actually help people here.
