Canon SX50, 50D, Sony A58.
Jack Hogan: We look forward to seeing the relevant EM1 images in the New Studio Scene updated to reflect performance with the new mode. The current ones show it sompm' fierce.
Right. The ISO 800 image shot at 1/320 sec is clearly sharper than the ISO 200 image shot at 1/80 sec.
D4s gets 1/3 stop less exposure than D4 in the comparison tool. For example 1/4000 vs 1/3200 sec at ISO 6400 (f/5.6 on both cameras). Here assuming that the lighting is the same, like it's supposed to be in the new comparison tool.
fenceSitter: "50 Mpixel CMOS sensor with almost twice the physical size of the largest 35 mm DSLR sensor."
On which planet are 1.67 "almost 2"?
Phase One IQ250 has (most likely) the same CMOS sensor and the price is $34,990, so this Hasselblad is actually quite a bargain.
falconeyes: This is both interesting and isn't.
It is interesting because the RED can capture 19 MP images at 85 fps, quite a beast. And of course, at 1/42th s, you just combine two frames into one, thereby halving effective base ISO for slow shutter speeds. For such combined double frames, DxO's measured performance is disappointing actually.
It isn't interesting because for stills with a focal plane or global shutter or flash photography, you can't use this technique without embedding a digital frame memory on the sensor. And this is nowhere near in time.
DxO knows it, which is why they don't list the RED in their rankings.
DPR's headline is WRONG: D800E still is #1 in the DxO ranking, it hasn't changed.
Think that the Red Dragon combines more than two frames at base ISO. The D800 has a 78% larger sensor and a lower measured base ISO than the Red Dragon (ISO 74 vs 104), but despite that the base ISO SNR comparison (see 'In Depth Analysis') shows that Red Dragon has a much better SNR (1-2 stops!).
Steen Bay: Well, if something sounds too good to be true... As far I can tell the QE of the Red Dragon must be quite a bit higher than 100% in order to get such a high SNR, and that's hardly the case.
D800 has a 78% larger sensor than Red Dragon and the D800 also has app. half a stop lower measured base ISO (ISO 74 vs 104), meaning that it can 'handle' app. half a stop more exposure, but despite that the base ISO SNR comparison (see 'In Depth Analysis') shows that the Red Dragon has almost 2 stops (5-6 dB) better SNR in the midtones. That's simply not possible, since the QE of the D800 already is about 50%.

Buhl213: How can the Tamron be ENTIRELY useless when cut in half?
Should be OK for half-format.
Steen Bay: Rather disappointing performance, I think. Lumia 1020 has a 1/1.5" sensor with twice the area of a 1/2.3" sensor like used in for example Panasonic FZ70, and yet the FZ70 has better SNR and DR if comparing at the same exposure (same 'measured ISO'). Shows that the 1020 sensor has a rather low quantum efficiency (less than half the QE of the FZ70 sensor).
@HowaboutRAW - I didn't, I was just commenting on DxO's test results.
Bervilat: So, this will be actually worse for base iso landscape photography?
Depends.. DR is better, and the QE is probably quite a bit better too, but the higher base ISO means that SNR 18% probably won't be better at base ISO than it was with the CCD sensor.
AndyHWC: I stopped checking DXO for a long time because its result don't always match what my eyes told me. Is it comparing overall picture quality or pixel noise. To fit 41mp in a tiny sensor, you expect noise to be bad in pixels level. Anyone don't like their 1020, I love to trade my HTC 8x with you.
The sensor score is about things like noise and DR, it doesn't take the resolution into account. Could be interesting if DxO also tested the resolution of the 1020 ('lens score'), which of course is its strongest point (assuming the lens is good enough).
The DxO score is based on the 'image level' performance (images downsampled to 8mp).
Rather disappointing performance, I think. Lumia 1020 has a 1/1.5" sensor with twice the area of a 1/2.3" sensor like used in for example Panasonic FZ70, and yet the FZ70 has better SNR and DR if comparing at the same exposure (same 'measured ISO'). Shows that the 1020 sensor has a rather low quantum efficiency (less than half the QE of the FZ70 sensor).
IQ180 has a wider ISO range than IQ250 (35-3200 vs 100-6400).
@DPR - According to DPR's news story earlier today the S-1 has a 16mp BSI-CMOS sensor. Is that correct? (would be a bit surprising to see the largest BSI sensor yet in a Kodak camera)
Joseph Mama: So, what exactly is so freaking NEW about these? I mean, a 20x compact zoom? We were there 3 years ago with the SX260.
Whats new? Apart from the even lousier aperture numbers...
30x zoom, EVF, RAW and focus peaking. That's new.
No Tv, Av and M modes? If not, then that's a pity.
Another important 'Pro': The GM1 is immune to 'shutter shock', both if using the mechanical shutter with electronic first curtain (up to 1/500 sec), and also if using the silent electronic shutter. Think it should have been mentioned in the review (sorry if I missed it), because shutter shock seems to be a rather serious problem on many mFT cameras.
petr marek: Great. Missing Foveon/Sigma, very important benchmark!
Well, the OOC JPEGs shouldn't need a warning, and a warning could be added to the RAW images (for example with red letters over the DPR logo in the center of the image).
yabokkie: not needed at all.
I just need a fine tuned low pass filter to guard high frequency noise, not the fake resolution. but what I really need is more pixels say well over 100M.
a good example how stupid users can change the market though.
The AA filter doesn't affect the high frequency noise (the noise won't disappear either if the subject is out of focus).
vapentaxuser: It would be interesting if you were able to take the G15 out at the same time and do some comparison shots between the two. Based on the sample shots, one thing that the G16 is still doing is overexposing and blowing out highlights just like the G15 did. You might as well just set the exposure comp dial to -1EV and leave it there.
That said, I'll bet it was an enjoyable camera to shoot with. Especially if the Canon claims of increased speed are true. The color performance is also very nice.
@Barney Britton - According to the specs on several Canon sites the G16 and S120 have a new BSI CMOS sensor. Do you knew whether that's the case or not?
