Unfortunately, I don't have the GRDIV yet. So no RAW samples from me anytime soon. But I think there are already some people with both cameras?
On the other hand, since both cameras share the same (or nearly the same) sensor, I would not expect a dramatic difference. The main difference we should see is higher sharpness because of thinner AA filet used in GRDIV. But as for the noise and RAW noise reduction, I would not expect any noticeable difference. But of course, I can be wrong

Thank you both for responding. Even though the sensor is the same, I would like to see few issues. The high iso banding is one. Also as we all know, raw is really never purely raw....It would still be interesting to see how grd4 handles NR.
I am disappointed to see ricoh using an old sensor for this camera, but it is the price to pay for not making your own sensors, and there is nothing better at the moment. It would also be interesting to see how the new canon s100 sensor compares to the old Sony sensor.

Now I wrote a small article where you can download some DNGs: http://www.electricgrain.net/2011/11/21/dng-comparison-ricoh-grd-iii-vs-grd-iv/

After that shooting I had no other system-crash. So perhaps the GRD IV was offended because of working with the GRD III at the same time ;-)
Just kidding, I also think it was the eye-fi card. Usually I shoot .jpgs, there I have no problems. I will try DNGs next time in the City with the eye-fi card and a regular SD-card, then I will see whether it happens again.

Hi pavel,
Almost six months since it's announcement, and to my surprise, we still don't have a grd4 vs grd3 comparison.
I have completely given up on dpreview, but in the past, we saw you, cristian and also amir compare the newest grd against the previous models, and or its competitors from pana / canon...
Maybe I missed it?
I realize that this site is not a professional enterprise and relies on personal efforts,so please don't get me wrong, I dont want to come across as complaining, whatsoever. Just curious about the lack of enthusiasm, and mostly on the part of ricoh, because I assume it is them supplying you with the test units.
Best,
Roni

Hi Roni,
Well, I fully understand your point and you can believe me, I'm really unhappy about the current situation. It's not about the lack of enthusiasm. I'm the same enthusiastic about Ricoh cameras as in the early Ricoh forum days. Unfortunately, since the birth of my second daughter (early last year), I'm facing complete lack of time. My work and family eats all my spare time. And this is also why I'm not asking Ricoh for new cameras to test. Simply, because I know how much time it takes to prepare good comparison, I see no point to ask for new cameras, no matter how curious I'm about them
Usually, Ricoh folks send me new cameras even without asking. But because there were some production constraints due to flooding in Thailand and possibly also because of the ongoing "mess" caused by the Ricoh/Pentax merge, they are a bit delayed with their usual delivery. On a positive note, just today, I was informed that they are about to send me the GRDIV and M mount samples. I should have them before the end of month. So I will try my best to find some time at least for basic GRD comparisons and some M mount photos with the unusual lenses I collected for the purpose of the M mount test.

Pavel, thank you for your post. Looks like you have your hands full with much more important and pleasant and also interesting stuff. Congrats on # 2.
Will be nice to hear your findings when you have a chance...I don't think i am alone here in saying that i find your test shoots and observations more valuable than the standard photo site reviews...

I had both 3 & 4 for a few weeks. Outside obvious features like IS, screen and 2-way level, I think the main differences in favour of the 4 are:
- probably less aggressive AA filter: improved low level details, but some jaggies as well (I much prefer AA-less cameras);
- slightly better color balance in AWB (3 had a magenta hue);
- improved lens performance (less flare in corners, resulting in higher resolution);
- faster autofocus (even if still slow compared to current competition).

M

Hi Guys,
Does anyone know why Ricoh don't use a 4/3 sensor on the GRD, or at least a bigger one? I love them, but wish they would improve the sensors.
Many thanks- Arthur

I believe it's to do with physics...basically a bigger sensor would require a bigger camera...it's to do with the distance between the lens and the sensor and the size of the lens too if you want to retain the same equivalent ('35 mm') focal length. Doubtless others can provide a more technical explanation but I think the same question has been asked elsewhere on the forum. At the end of the day it's all about compromise and Ricoh would point you at the GXR with an 'A' module if you want a bigger sensor.
Personally, I think the sensor and processing engine in the GRD IV is pretty good for the sort of photography I indulge in and for prints up to A3.

Hi Arthur,
Richard is right. Bigger sensor would need significantly larger GRD body/lens. Either this or significantly less wide and/or less fast lens. GRD sized camera + 4/3 sensor = you can forget about 28/1.9 lens
Aside the body/lens size limitation, there is also another important reason why we cannot get the 4/3 sensor for the GRD. Simply, there is no commercially available 4/3 sensor! All 4/3 sensor are produced by Panasonic and the only other camera maker allowed to get them is Olympus. And the same apply for other "larger" sensors like the 1" sensor from Nikon used in J1, or the 2/3" sensor from Fuji used in X10 or even the 1.5" sensor from Canon used in G1X. All these sensors are proprietary made and not available to 3rd party manufacturers.
Ricoh is traditionally tied to Sony sensor production, so I guess our only hope is that Sony will produce something new and noticeably better for GRDVI than existing 1/1.7" CCD, which already shows its age and limitations.
