Ricoh GR vs GR II : Blue/Purple Orb confirmation request

Happy holidays doc!

You seem to have exactly the right spirit for the holidays...First of all, I know for a fact that Ricoh changed the GR lens design precisely because of the flare issue. And even more interesting for you (and others) to know that they changed the lens design before gr2. Unfortunately I cannot tell you starting which serial number, but later batch of GR's already had the improved lens design. So it is very much possible that your GR belongs to the second group which may explain your reaction. As of the example I shared: that's not terrible pp, that's an actual crop of the dng file.

Happy holidays, once again...
Not cranky - I just like to stick to the known facts, and having long experience of engineering projects large and small I am wary of "proof by repeated assertion".

I don't understand what "an actual crop of the dng file" means. "Linear" DNG is a partly-processed image file that you can visualise directly. However, I understood that the DNG file from a GR is a proper raw file containing the non-demosaiced RGGB Bayer data. If you visualise this data directly it looks like four greyscale images. The example you linked to looked like a crop from a processed image where the darker region had been lifted and the saturation cranked-up.

I'm not saying the GR is the most perfect camera on the market and can never be criticised (this isn't the Leica forum). I'm saying that there is some flare, generally well-controlled like most modern lenses, and the conditions where it is likely to impact the image quality are understood and predictable. There is no need make up a new vocabulary to discuss it. Sometime I think people who are highly critical of the performance of modern digital cameras should be sentenced to 6 months with a folding Zeiss roll-film camera with an uncoated Tessar lens.

Wishing you and your family a happy holiday also.

Ok, DJ, this is a much more measured answer, thank you!

I am not spoiled or delusional enough to call GR, (or any modern era camera for that matter) unusable or crap because of a minor issue such as lens flare. But that shouldn't stop us from discussing a problem when we see it. As I tried to explain, Ricoh considered this to be an issue and addressed it themselves. And as I also mentioned in my previous posts, Ricoh considered this problem urgent enough, and didn't even wait for GR II before they redesigned the lens unit.By the way, I never called the GR flare an "orb" myself, but under *extreme* conditions it sure manifests itself much differently than a typical flare artifact. Regarding the example I shared: Without getting too pedantic on what a "crop from a raw file" is, I think everyone understood what I meant: what you "see" on a computer screen when you *first* open a raw file in your favorite raw processor. Of course, every raw developer will need to process the data before you "see" something on your screen, but you sure can't call that "terrible pp", just as you can't call the flare issue as "forum BS", just because someone used the wrong vocabulary to describe it.I will need to look up for the source file, as unfortunately at the time when I shared it, I made the mistake of not naming it properly...not easy for me to look it up among 15000 files now! But if I happen to find it, I would challenge you or anyone else to retain it with proper post processing techniques. Not that it matters, because it was just meant to show the flare in its worst form.
From dpreview: "So the core of the camera remains the same then. But that's not terrible news, given how good the GR was. The GR II still uses the same well-regarded 16MP APS-C CMOS sensor and a 28mm equivalent F2.8 lens that is impressively sharp all the way to the corners."

This seems to contradict your view that the lens has been redesigned. Do you have a reference for that? I am curious.

DJ, here is a link that you may find more convincing than my personal experience:


And while the lens specs are broadly the same, the new version has two 'high-precision' aspherical elements and one high-refraction low-dispersion element to produce what the company says is the best GR-series lens yet.

I have no doubt that this improved lens design went into at least some of the GR make 1. my camera went to service for a problem that required the change of lens unit, and when it came back it no longer suffered from the flare issue as much as the old one. That was long before the GRii was out.

From Ricoh in 2013: "while minimizing distortion and chromatic aberration by incorporating two high-precision aspherical lens elements and a highly refractive low-dispersion glass element in its optics". Who knows?

@rondom - that is very interesting! My GR was from the first batch of preorders when it was announced. And yes, I have those intriguing purple flares.

not sure, what else to say really..
I only know the history of the camera that I own: if something is different about it, I try to look at "facts" as much as you do....i myself don't believe in magic, voodoo or miracles...
Let's leave it here, and everyone can decide for themselves...
For all those that care:
my GR which was prone to extreme flare had the following serial number:
0310112xx

hi Archiver, you may want to share your serial number here (leave out the last two or three digits if you wish for privacy) others who own GR make 1 but cannot see anything unusual about their flare may choose to do the same as well...

Thanks for this .

My GR serial is

141090xx (only 8 numbers , yours 9 ? )

Bought in November 2015 : with the blue flare

Mine is 1710xxxx, bought at the beginning of 2014. I looked through a lot of images with bright lights sources, including some with the sun in the frame, and saw remarkably well-controlled flare. I didn't see any unusual purple flare. I found this one image, taken with some fairly extreme back-lighting, where the flare has a purple hue. This is a processed version, but the "purpleness" is about the same as the default version.

Thanks for sharing. That's a lovely picture, and also lovely use of flare...hard to tell, though, how different copies of GR make 1 would have rendered this particular scene. Your GR has a high serial number and a recent purchase date. If you have *never* encountered the *opaque* magenta artifact in challenging situations, I would argue that you might have the revised lens design. Of course, this is speculative information, and I have nothing to prove other than my already too much repeated story.

In the latest Sample Gallery for the Sony RX1R II, this sample taken into the sun shows flare with a strong strong purple / green coloring: DSC02142.acr.JPG.

It is certainly possible that Ricoh modified the spectral response of the anti-reflection coating to adjust for the characteristics of the Sony sensor, or something like that, but that is pure guesswork.
