dgeugene1: The specs say sensor size is 5472 x 3648 or 3:2 but the sample photos (generally worthless) that I saw were all 4864 x 3648 or 4:3. Why is this?

As to worthless samples on DPR I really miss Jeff Keller's repeated San Francisco scenes. The picture of the Transamerica Pyramid by itself would be worth more than all the pictures here.

And how did Jeff manage to find so many perfectly clear days in SF?!

Please send Simon an e-mail requesting that I get flown to SF every two weeks to take photos. Thanks!

Retzius: DPR is really pushing this camera.

3 articles with the same theme in one day:

A Little Bit Better
What You NEED to Know
Why It Matters

We get it, its a small upgrade but you really like it, we NEED to understand that, and why that matters, apparently.

And you'll never believe what happens next!

GlobalGuyUSA: Does anyone know if its possible to have "FOCUS PEAKING" in LiveView with a Nikon or Canon DSLR? I noticed they added Zebra stripes to the D810 -- but what about Focus Peaking in LIVE VIEW mode? Isn't this possible?

Its a shame Nikon named the new horizon level "Split Screen" because what I am thinking is that in a Df 2 camera, when in LIVE VIEW, the user should be able to have Focus Peaking + a simulated "split screen" (Katz Eye style) for manual focus (by magnifying a circle in the center and applying highlights when its focus).

Just a thought!

No Nikon DSLR has focus peaking in live view.

D1N0: Isn't this simply a name change and will photo's for os-x be as capable as aperture?

Looking at the screenshot it seems pretty dumbed down.

tmy: How about the AF sensor?

Is it the same or newer than the older D800/E?

It's the same sensor (Multi-CAM 3500FX)

In reply to:

Daniel Bliss: Oops, DPR. The current D800 models already have 1.2 crop mode. All that's new here with that mode is raising the capture rate from 5fps to 6.

Also an interesting spec; X-sync is 1/320th. So this means all flash units, not just FP-capable Nikon ones?

Corrected the X-sync to 1/250 sec. Nikon says it can go to 1/320 sec with a drop in flash range.

sierranvin: The comparison table says Canon model = 12mp
The Canon-specific page says it has 16mp
This review is providing me with a less than pleasing handling experience.

It's 12.1MP. Camera-specific page has been fixed.

DavidsfotosDotCom: "The previous iterations of the AW120 (the AW100 and AW110) have a bit of a bad reputation for leaking and then failing. In our testing of both the AW110 and AW120, we had zero problems."
So was the seal improved, or was the test to short & shallow to determine?

They are almost identical. We don't have an AW110 anymore, but if I think the part of the seal over the battery is slightly more substantial now.

peevee1: DPR wrote: "There's no shortage of bells and whistles on the WG-4. Before we get to those, there are a pair of new features that many will find useful. The first is shutter priority mode, which offers a range of 1/2000 - 4 sec."

But your specs say the maximum shutter speed on WG-4 GPS is 1/4000s. Which is it? Or 1/4000s is only available in auto mode?

1/2000 sec is the max in Tv mode. I'm guessing it goes higher (using the e-shutter) in Auto mode.

Mike FL: I have Oly TG-2 Plus Oly's WA and Tele converter as a backup camera for bad weather. For $500, I get 19mm - 170mm which can be used for ALL weather. I like it/them even the IQ is so-so.

I like the TG-3 as it has WiFi, but I'm not sure if the IQ is lower than TG-2 as TG-3 has more MP.

I HOPE DPR will add the ability to compare the TG-3 with TG-2 in "Studio Comparison"...

Unfortunately we didn't shoot the new test scene with last year's cameras, and they have long been sent back. Sorry!

Jeff Keller: Just a heads-up that we're aware that the Ricoh WG-4's ISO 200 studio test scene shot is out of focus. This should be resolved in the morning (our time).

Thanks,

All of these have been fixed.

Tobias1234: Last year I tried the Olympus TG-2 which was one of the 2013 recommendations. I was really shocked about the bad image quality compared to any other camera (e.g. S95, TZ10, RX100, FZ38, some mFT-Bodies) I have used before.
The lens of the TG-2 is fast, but it's so soft that open wide is unusable. The JPEG engine was also one of the bad ones.

I can not agree to the 2013 and this new 2014 comparison, because there is one really important feature which is a must for UW photography: RAW support. Without RAW the pictures will have heavy false colours and the UW programs will lead brownish or blueish color casts - depending on the distance to the subject.

After my bad experiences with the compact UW cameras, I tried a RX100 in a cheap housing (Meikon). The quality differences to the candidates is so big, that I can't understand what cameras like a TG-2/TG-3 are good for.

Even a cheap Canon S95 in a cheap Meikon housing (my backup) is lightyears away from UW cameras like a TG-2/TG-3.

@Greg VdB: the reason for the comments is that these cameras appeal to a broader audience than our 'regular' users. These people aren't doing pixel-level analysis- they want something their kid won't break that can be used in the pool or at the beach. When my 6-yo niece wanted a 'real' camera (Fisher Price doesn't cut it), I got her a cheap Panasonic rugged camera for that very reason.

I don't think we're defending poor image quality at all. At 100%, they're all bad - and I'm sure the manufactures know this. As long as they keep selling, I don't see why Canon, Nikon et al will put in a larger sensor or offer Raw. As someone who likes to take u/w photos, I'd love to see something like an underwater RX100. Unfortunately, I don't see that happening.

Marty4650: It might have been interesting to see how well the Nikon 1 AW1 performed against these cameras. Compared to the four cameras reviewed, the Nikon 1 has a "huge sensor."

We (I) did an article about using the AW1:
http://www.dpreview.com/articles/9476429038/swimming-with-the-nikon-1-aw1

It's also $800-$1000, which is why it's not on the "other cameras" page :)

thx1138: This will be a race to the bottom and hopefully literally and not metaphorically. Send them all to Davy Jones' locker I say!

I reckon you should have thrown in the Nikon AW1 as a reference just to see how the tiny sensored jpg only monstrosities compare, not that the AW1 is without issues.

Sony needs to make an UW version of the RX100III.

>Sony needs to make an UW version of the RX100III.

I'd buy that in a second!

Augustin Man: 1/16000 sec?! Sure isn't one zero too much?

It's an electronic shutter once you go past 1/4000 sec or something like that (don't have the specs in front of me).

EthanP99: what is the flash sync speed

I believe what Richard says is correct, according to the spec sheet.

Rodrigo Ayres Bordin: Hi! Are all the underwater samples done without flash? For underwater pics, you could add the depth they were taken...

For some of the cameras the flash was used. I never needed it with the Canon, so I never forced it on.

ChrisAN82: dpreview staff: Did you happen to take any video with the TG-3? If so, could you hear a constant clicking noise during video playback? The TG-1 and TG-2 both suffered from this and it is believe to be caused by the microphone picking up the noise from the AF system.

We have some sample videos that will be posted soon. Just fooling around with it in the office, I didn't notice any clicking sounds.
