Henrik Herranen: I think there's a slight error in the caption that says: "[...] The 18.7 x 14mm sensor size that Canon has been quoting appears to refer to the 3:2 crop area [...]"
Shouldn't this read "18.7x12.5" which is the number you say Canon quoted in the text?
Also, in the text: "(rather than 24-12mm from a 15.1-60.4mm unit)"
I guess you mean 24-120mm.
Yes - I've corrected both (The second error should have read 24-112mm). Thanks for bringing them to my attention.
Zoron: i would prefer 3x zoom, 24-75mm f1.4-2.8
@tkbslc - actually it's very close to 1EV at both ends (within 1/6EV).
VaLeX: I'd like to know more about:1. Sensor size: in relative terms, how does it compare with APS-C, m4/3 and Sony's 1"?2. How are the control rings on the lens working? Fly by wire? How fast and responsive are they?3. I don't think I've missed something, but the camera is not weatherproof, right?
APS-C (Standard) ~ 23.5 x 15.6 = 367mm2
APS-C (Canon) = 22.2 x 14.8mm = 329mm2
1.5" (G1 X Mark II 4:3 crop) = 17.9 x 13.4 = 240mm2
1.5" (G1 X Mark II - 3:2 crop) = 18.7 x 12.5 = 234mm2
Four Thirds = 17.3 x 13.0 = 225mm2
1" (RX100) = 13.2 x 8.8 = 116mm2
1/1.7" (Most Enthusiast compacts) = 7.4 x 5.6 = 41mm2
1/2.3" (Most compacts) = 6.2 x 4.6 = 29mm2
Eigenmeat: 12.8MP at 2014 is a bit of let down at 2014 to be honest. Especially with a sensor this large and lens this fast(less diffraction prone). Sony can squeeze fully usable 20MP 1'' sensor on its RX100/RX10 series (especially the RX10). No reason Cannon cannot squeeze a good 16-18MP on a 1.5'' sensor.
It's pertinent to try working out the area of a Canon APS-C sensor and the size of this one, then multiplying the ratio between the two by 18m.
We were told the original G1 X's pixels were the same design as Canon's DSLR sensors and this appears to continue that relationship.
Photato: No PDAF points on Sensor it seems.The Autofocus more likely is Contrast Detection slow.I like the lens Focal range and apertures though.As for the Muti-aspect sensor, the emphasis should have been 16:9 and 3:2, and not 4:3.
@Photato - 'Contrast Detection slow' seems like an odd phrase, given that some CDAF cameras (eg Olympus E-M5) are among the fastest on the market, in terms of single AF acquisition.
piratejabez: Thanks for these!I think the titles for the first two images are swapped—the first says "18mm" and the second "55mm" but it should be the other way around. The metadata is correct.
How do you know I didn't stand much further away for the 55mm shot?
You're absolutely right - I've now corrected it.

Petroglyph: Very clever sensor design, Sigma. Photo sites in the bottom two layers are 4X size comp to the top one. On the 75mm fov equiv one make it f/2.0 or 1.8, please.
All three cameras will be F2.8, as per the Merrill versions.
Artpt: @DPReview, was there any press release given regarding compatibility with Olympus lenses?
If there'd been a release, we'd have published it. As mentioned in the article, DFD autofocus will only work with Panasonic lenses. Olympus lenses will still work, using conventional CDAF (which is very quick), they just won't be quite as fast nor, in theory, as good at tracking.
Esign: This is some of my ratings, if only based on this test scene:Fuji X-T1 compared to fullframe cameras Nikon D800, Sony Alpha 7R, Canon EOS 5Diii:Nikon wins everything, low ISO second Sony, third Canon, high ISO second Canon, third Fuji (!).Fuji X-T1 compared to APS-C cameras Nikon D7100, Canon EOS 70D and M34 Olympus OM-D E-M1:low ISO first Canon, second Nikon, third Fuji, medium and high ISO first Fuji, second Olympus (!), third Nikon.
@Usee - I disagree that the scene is a source of misinformation - just because it's not the information *you* want.
It's reasonable to assume the majority of people judge their exposure by whether their JPEG is the correct brightness. That's what the ISO standard is based on and that's what the logic of our test is based on.
If a camera is needing a different shutter speed to achieve this, we report it, so that you can see which cameras need more exposure than you'd expect.
The alternative is to apply fixed exposure parameters and then present images of different brightnesses - which would be hard to interpret and wouldn't answer the question 'how would they look if they were all the same brightness?'
The question is whether we're trying to model real-world usage for the majority of our readers or conduct tests that end up appearing esoteric to the point of irrelevance.
ThePhilips: DRP, please cover in details the DFD (Depth From Defocus) feature! Thanks.
Others have made a presentation -http://www.imaging-resource.com/PRODS/panasonic-gh4/panasonic-gh4A.HTM#DFD- but there is no real-world test of it yet.
There are no testable units yet, we're told. It'll have to wait, I'm afraid.
nimrod1212: This is a fairly summarized feature set review here I understand, but in order to record 422 at 10-bit am I right in thinking I still have to have an external recorder? Maybe I'm misreading something. I care nothing for 4K, it is the increased dynamic range and reduced compression for HD that would make me want this.
Correct. Internal recording, even at ALL-I is 4:2:0, I believe. Alternatively, 4:2:2 8-bit over HDMI, 10-bit if you *just* use an external recorder.
rrr_hhh: "and a minimum shutter speed of 1/8000 sec "
Isn't that the maximum shutter speed, being the fastest one ?
@trekkeruss - Tv is certainly a less ambiguous term.
1/8000th is the shortest time value and the fastest shutter speed.
Yes, it is. It's now been corrected.
Thanks for highlighting that.
mpgxsvcd: "NTSC (offering frame rates of 23.98, 29.97 and 59.94), PAL (25 and 50) and Cinema (24) and requires that the camera be rebooted to switch between settings."
Possibly (and I'm speculating here) because you need to re-set the clock speed of most of the processors?
brettchris: regarding the viewfinder size: i got very excited by that comment but now i am confused:
the specs for the XT1 viewfinder quote 0.77 magnification- off a APS-C sensor which would be 18x12
whereas the canon 1DX specs shows 0.76 from a full frame 36x24 = 27x18
is there a mistake or am i missing something?
Fujifilm is quoting the figure using a 50mm *equivalent* lens - meaning the figure is directly comparable to the figure for the 1D X.
Traditionally manufacturers have (unhelpfully) quoted all systems using an *actual* 50mm lens which, as you say, then required you to take crop factor into account.
We'll check whether CIPA is encouraging a change in the way this is quoted and we'll make sure it's clear in our database.
Long story short - you should be excited - the X-T1's viewfinder is vast.
stern: travel companion? why would i choose an ILC for travel? My travel camera is the pentax mx-1. compact, rugged plus incredible IQ. IMHO IQ of the mx-1 is on par or better than the Sony RX, which is probably due to the mx's better lens (sharp!). travel = compact.
@Tord S Eriksson - neither the Q nor K-mount range offers a 6-14mm F1.8-2.5 lens so, while interchangeable lenses offer greater scope for flexibility, they don't necessarily allow a match for what the XZ-1/-2 and MX-1 do.
Equally, the MX-1 offers more control over depth-of-field at the long end of its zoom than the RX100, which is likely to mean competitive image quality in low light at longer focal lengths, too. As such 'in a different league' is likely to depend on what you shoot.
Usernamefail: Never seen Wells look so empty - now I know when to visit!
A little further South than that - the street is in Frome, Somerset and the Cathedral is Salisbury. ;)
BernardRoughton: Where is the interesting shot of the split street taken?
Frome, in Somerset - it's a really pretty little town.
David Hurt: The 3rd Image will NOT load - it says Error.
That should now be fixed. Sorry about that.
Expat Nomad: @R Butler. It doesn't seem to be mentioned (apologies if I have missed it), but did you use video at all? If so, how did you find it to be?
I've not used the video a great deal - I was a bit pressed for card space and don't tend to think in terms of video.
I'll be shooting some, though, so will cover it in the review.
