In reply to:

Alphaville: These expensive small-sensor cameras really should implement computational photography to get depth of field control. I might orherwise just ad well put up with an iPhone X or similar.

DxO One is now discontinued. I recall its SuperRAW format matched some APS-C sensors as per DxOMark. Oh, and I don't really cry foul on that.

In reply to:

noisephotographer: Skin tones are not bad. But the image processing still leads to blown out highlights/too dark shadows. Certain smartphones (Google phones and for low-light conditions Huawei P20 Pro) handle this much better.

You're comparing apples and oranges. Pixel defaults to multi shot HDR while Sony only occasionally uses it in Superior Auto mode. A better comparison would be Auto HDR on Sony with the phone cameras.

So 46mm is telephoto, huh? Looks like I've been learning garbage all these years where 46mm is supposedly "normal".

On article Does sensor size still make a difference? (1067 comments in total)

Great Bustard: For the benefits of larger sensor systems, I'd have said:

• Higher resolution
• Option for a more shallow DOF (if desired)
• Lower noise (although this often requires a more shallow DOF)
• Greater DR (with the remarkable exception of the 6D2 :-) )

While the last three bullets were mentioned, the first bullet was not, and it's the most important reason for some people.

@Great Bustard, Thanks for the information. I didn't actually know the exact difference between lw/ph and lp/mm.

Number of megapixels is not a great way to measure resolution. The smartphone cameras have a lot of pixels but they're nowhere near the amount of detail that can be shown in those pixels.

A good way to show resolution potential is lp/mm and a good way to decide whether large sensors do offer a resolution advantage is to survey the common lp/mm numbers reported for each format. You'll find that it would establish the OP's argument as a fact.

Lastly, if all of the above is too technical, here's a simple proof. If you see the photo below on a phone screen, it'll be hard to tell what sensor it came from. However blow it up to a desktop screen size and you'll see the craters in the moon, unlike any phone sensor out there. It's just a THREE Megapixel image and it lays the smartest phone sensors to waste.

new boyz: Photography is becoming more and more than just about the lenses and sensors. That's why Nikon is falling behind (I think). They are not really into software things. Nikon (and other manufacturers for that matter) must offer cool tricks like this to attract casual users.

Nikon should partner Apple.

On article DxO OpticsPro 11 brings advanced Raw noise reduction (110 comments in total)
In reply to:

Tahir Hashmi: Long time DxO Optics Pro user here and I just did a quick comparison between DxO 11 and DxO 10 regarding PRIME 2016 NR and Spot Weighted Smart Lighting. I'm happy to report that the improvements are real.

First off, my favourite High ISO Test shot for NR.
PRIME 2016 https://www.flickr.com/photos/code_martial/27142991210
PRIME 2014 https://www.flickr.com/photos/code_martial/15610784099

I've rendered this shot previously with PRIME (2014), LR 5 and Capture NX2 (links in the photo description). PRIME 2016 is head and shoulders above the methods I previously tried. It's got better details, colour saturation, shadow areas and smooth area rendering.

[1/2] continued...

As you rightly mention, this is not an objective comparison as in my other post (http://www.dpreview.com/news/7419541954/dxo-opticspro-11-brings-advanced-raw-noise-reduction?comment=4093240848). The goal here is to see what's the best I can get out of the package.

The input here is the exact same raw file, so the exposure is definitely the same. The brightness and colours are a consequence of PRIME's improvement. In all previous renderings, I had to pull exposure and desaturate a little to control luminance / chrominance noise. Essentially, what you don't see in other versions is not worthy of display.

Distortion correction (or lack thereof) is inconsequential and not worth dwelling over. It's only an aesthetic choice that I reverted between DxO 10 and DxO 11 conversions.

Next up, Spot Weighted Smart Lighting.

See https://www.flickr.com/photos/code_martial/26810489144

Starting with the panel on the right (yup, I'm going backwards), we have default (HQ) NR and default Smart Lighting. There are 2 problems with this panel. The hair and black background have a slight green tint, and the skin has a patchy rendering instead of uniform gradients.

The panel in the middle has PRIME 2014 NR with default Smart Lighting. There's marginal reduction in patchiness of the skin but the tint remains.

The panel on the left has PRIME 2016 NR with Spot Weighted Smart Lighting. The tool automatically detected the face and adjusted lighting accordingly. The green tint is gone. The skin rendering with PRIME 2016 is quite smooth and the details (e.g. eye lashes) are well defined.

All-in-all, this looks like a worthy upgrade.

What a scene! The banner image crop in the Resource Magazine article looks even better with the curvy bits at the bottom cut out. Totally worthy of living room wall-space.

In reply to:

Hugo808: But why does it overexpose? Isn't that, like, a major drawback in a $2000 camera?

My old D40 did it and it drove me nuts. I don't want to fiddle around with +/- buttons when I'm shooting!

From what I've seen, the more expensive it is, the more fiddly a camera becomes – at least as far as initial customisation according to personal preferences is concerned. If you don't like fiddly, Sony has arguably the best Auto mode, that too in sub-$1000 cameras.

Firstly, you can "fix" it by setting a bias for each metering method independently, so when the camera shows 0EV on the exposure meter, it's actually applying the under/over-exposure bias you specified.

Secondly, with the inclusion of highlight priority mode, it makes more sense to bias the default metering a bit brighter to get richer tonality in lower contrast pictures where highlight clipping is either minor or non-existent.

In reply to:

Chev Chelios: Is it just me who was expecting to see the obvious "sideways-on" photo of the converter mounted on the camera (to judge its overall depth once fitted), but found there wasn't one?

You can see that on Fuji's website. It's quite deep: http://www.fujifilm.com/products/digital_cameras/accessories/lens/conversionlens/x100wideconversionlens/index.html

Edit: oops, that's the wide angle converter. Never mind.

Looks like the RX10's competition has arrived. Would be interesting to see how these two and the rumoured P8000 (1" sensor, f/2.0-3.0 24-120mm lens) would compare with each other.

On article From NEX to Alpha: Sony introduces 20 megapixel a5000 (151 comments in total)
In reply to:

greypixelz: This alpha bs is getting a bit tiring. It's clear they are using it to confuse the users. The fact they made the a5000 similar in look to the NEX 5 series shows intention on sony's part to confuse the new adopters. Wonder what they will call the NEX 5 line now.
Is the 20Mp sensor better than the 16Mp sensor in terms of dynamic range and noise performance?

*I jumped the trigger. Never mind.*

In reply to:

Artistico: This is clearly aimed at someone who thinks their smartphone's built-in camera isn't good enough, yet they don't want the hassle of bringing along a compact camera as well as their omnipresent phone. I think it has good market potential and I wouldn't mind seeing more camera manufacturers getting in on this idea to give us a better choice of smartphone camera modules.

Now. If only the QX100 (and the RX-100 for that matter) had a more sensible 10 megapixels - it can't resolve any more detail than that anyway, so the extra megapixels only serve to reduce dynamic range and increase noise. I can't speak for the QX10 from experience, but 18 megapixels in a 1/2.3" is way to much.

I've never felt the RX100 lens lacking in any way to match the 20MP sensor. At 1:1, RX100 pictures look much sharper than what I get on the 24MP D7100 with any of 35mm f/1.8G Nikkor or 16-85mm VR Nikkor or 55-300mm VR Nikkor.

On article Just posted: Sony Alpha NEX-6 Review (330 comments in total)

I was trying to compare the build quality score for this camera against others, and it seems like the widget is not showing the difference against other cameras.

The build quality rating of this camera is shown as 10/15, which is even less than that of NEX-3 (11/15) and PEN EPM-1 (11/15). I'm wondering if it's a bug in the score widget.

Can someone qualitatively compare the build quality against cameras like Fujifilm XE-1, NEX-5, etc.?

javidog: Seriously guys. You cannot be serious on wasting an ounce of energy on reviewing such a camera. Surely there is better equipment out there for y'all to play with and write about.

marike6, all early reviews of this camera have given it "junk" rating. DPR could at least have deprioritised reviewing this camera over better ones. I doubt if their testing method is so unique that they might show a junk camera as a winner.

Oh, let me check the conclusion to see if they actually did this...

In reply to:

GaryJP: Hmm. All these people banging on about it being a pocketable camera. Don't your pockets have pocket lint?

It's the last place I'd put a camera without a case, and with a case it isn't exactly pocketable.

I carry mine on the wrist strap, ready to shoot, which makes it only mildly more convenient than many other small cams.

I slip it in along with a piece lint-free microfiber cloth that I got free with my eyewear. That solves the pocket-lint problem and still leaves the camera more freely accessible than from a camera case.
