DxOmark (Click here) published the RX1R test and compared it with the RX1 model. The RX1R is indeed sharper but the truth (according to DxO) is that the it comes at a cost. There is a tiny bit less dynamic range on the newer RX1R. But as we discussed here many times before, these tests are certainly to take not too…seriously 🙂

DxOMark just told everyone their score is a joke. Low pass filter removed and smaller dynamic range? Maybe every camera should have a big fat low pass filter to boost dynamic range.
Low pass filter and DR have nothing whatsoever to do with each other.
There are two reasonable explanations:
1. Sample variation – though this would be a rather large anomaly
2. For whatever reason Sony altered the sensor somewhat – maybe to reduce dark current, temperatures, cross talk, or whatever.
The DxOMark scores themselves should no be looked much at all – instead the the results of the individual measurements are very valuable if you can understand them.
I think people are mislead to think that removing some sensor filter is just a matter of removing it physically and that’s it. I think this requires rethinking of many algorithms for image processing, video processing, etc. because all the old algorithms rely of some corrections being made by the filters.
I think it’s just the measurement error range…
exactly
Almost a stop?
Not likely to be a measurement error as I am sure they have double checked it due to the disparency. More likely Sony has altered the sensor to improve some other property – DxO doesn’t measure for example dark current, sensor temperatures, pattern noise… and this has caused the slight dip in the DR at low ISO.
it is smaple variation or measurement variation or error , their test is not perfect testing just one copy of each lens or camera to score all is so lousy, imho.
One stop would be a huge “measurement error”.
I wouldn’t call that a “tiny bit less dynamic range”. It’s more than a half EV less, which, unless Sony has really lousy QC, is a much greater difference than could be accounted for by mere sample variation.
unbelievable. they wouldn’t publish a test result like that unless they were sure about it. the difference is not a tiny bit at all. what did Sony do to that camera?
If they test on the same sample once every week you would see how it spreads. Anyone who knows what accuracy they state?
over all score is not important. this clearly shows DXO actually think a bit better DR is more important than a bit better high ISO.
but for my type of shooting a bit better high ISO of the R is more important than a teeny bit better DR of the RX1.
with that said , I think this is within measurement variation or sample difference and nothing really serious.
If this is within measurement variation, I’d say it is serious.
So you think those differences are not going to hamper your shooting style? I was worried, glad you’ve said that.
Dynamic range and good high ISO capability are both very important. But it should be said, that while the older RX1 may have a slighter better DR than the RX1R, the 13.6 EV range of the latter is still very good indeed. It’s better, for example, than anything they’ve measured from Canon or Leica and is only slightly lower than the D800’s DR.
I am surprised. Then again, I always suspected inconsistency since the A99 score was so different to the RX1 and D600 when it is the same sensor and, in the case of the Sonys, the same imaging engine…WTF?
The top 6 sensors tested are Sony. Too bad the top three are Nikon cameras. Maybe Sony can up the ante with the next gen sensor in the upcoming ff a-mount and Nex. I just hope the autofocus is stellar.
