On article LG G6 camera review (126 comments in total)
In reply to:

Mike FL: Lars Rehm;

Please test the G6's REAL ISO, I have G5 which is at least overstate ISO one stop if not more comparing to my SONY RX100.M3.

Please test G5 too.

Hi Mike, with some sort of computational imaging going on on most smartphones ISO numbers really don't mean too much anymore on those cameras. Yes, they give you an indication of sensor gain but they tend to be far off "real camera ISOs" on most devices.

(unknown member): "a slow-motion mode that can record 960fps footage at 720p for a fraction of a second"

Is there a point to that? Or is it just a "look what we can do" gimmick?

well, at 960fps a fraction of a second recording converts into several seconds of playback...if you get the timing right you can indeed achieve very nice effects.

At the launch event the designers pointed out that the V30 had rounded edges vs the Samsung's more pointy ones :)

Ace of Sevens: F1.7 on a 1/2.55" sensor is the same physical size as F2.4 on a 1/3.6" sensor. Presumably, it's done this way because they need to have identical depth of field.

no, it's a smaller sensor with a smaller aperture...they have to do this to keep the camera module small enough to fit into a slim smartphone.

piratejabez: (The headline says 20GB... for a second I thought it was a TBT :)

Also, "4GB version" in the description.

Thanks guys, all byte confusion corrected now :) Those are the prices in my WD press release.

In reply to:

joe6pack: Come on, DPReview. Is it really so hard for you guys to publish the sensor size and focal length when you mention the aperture size?

Or just say, "we didn't bother to check the sensor size but we are sure you can find it from the comments below".

If you'd actually read the article you'd see that I've made a comment about sensor size.

Sangster: Sharp is no longer a Japanese company. It was acquired by Taiwanese based Foxconn.

I guess it's then a Japanese company that is owned by a Taiwanese one...

On article Hasselblad to open first own branded retail store (20 comments in total)
In reply to:

landscaper1: If all this store will sell is 'blads, then I have to wonder whether it is simply a PR gambit or if Hasselblad seriously expects it to be a profitable enterprise.

I am sure there will be Hasselblad-branded bottle openers, fridge magnets and other knickknack ;)

keeponkeepingon: "That said, quite a few buyers will probably get the Pictar for its attractive retro-look alone"

Yeah that's a bit optimistic.

Question: Does it work with an iphone in a case? If not then they've elimitated 90% of the iphone totting public.

They say it works with the official Apple case, so I'd assume it works with most "normal" cases that aren't too thick or bulky.

In reply to:

John Driggers: The Kickstarter project for this is filled with complaints about non-delivery of grips to people who funded the project--yet they have satarted selling to the general public. Also lots of complaints about shipping the wrong grip. Lots of reports about iPhones overheating because of the app. Yet DPreview posts a more-or-less favourable report.

Does not bode well for the credibility of DP Review.

well, I can only test the unit that I have received and for me it worked as described in the article. I cannot speak for anyone else.

In reply to:

NowHearThis: The only issue I have with my iPhones' camera is that I can't assign a volume button as the shutter release. That would make it handy in some situations.

Any iPhone I have had uses the volume buttons as shutter by default. Of course that doesn't give you the half-press function you get with the Pictar though.

In reply to:

tkbslc: I can understand using a crop and a higher resolution sensor to offer additional "reach". But why would the engineers then think that we want the cropped image interpolated back to 20MP? Leaving it at a cropped 12MP makes for smaller file sizes, the same amount of real detail, and no worse resolution than the competition. Hopefully there is a software update with the ability to turn off the interpolation.

yes, I thought the same, it would make more sense for both cameras to output 16MP images anyway

The Name is Bond: Far too much unintelligent pixel-peeping going on here. These images need to be normalised and compared like-for-like at equivalent ISOs. This camera has impressive ISO performance for a phone.

"Processing of JPEGs are horrible. Even at ISO 125 clouds in one of the images look like a painting."

It's actually quite good when you compare it, normalised, to an iphone. Iphone's only reach 6MP detail at ISO 25 in very bright light.

In fact it's smashes the iphone and I think it's probably better than a google pixel.

Look at the one portrait. Indoor, ISO1600 and yet just about ok at an ipad friendly horizontal res of 1600 pixels. And good at a more reasonable 1080.

problem is that the Pixel uses ISO 50 in bright light, the OnePLus often goes much higher...you should not compare at same ISO level but at same light level...it's the result that counts, it doesn't matter what ISO the camera uses for that.

In reply to:

noisephotographer: I just looked at the exif data and although the exif data state 4.1mm for both cameras (which must be wrong), the exif data states that the equivalent focal lengths are 24 and 32mm... So just a 1.33x zoom + digital zoom..
I would say that selling a 32mm camera as a tele camera is nearly a crime. ;)

in what exif reader is it saying that? Mine does not show any equivalent focal length....in any case I am not sure I would trust the Exif at this point, there is quite a bit of suspicious data in there.

In reply to:

noisephotographer: By the way it's not good that dpreview accepted to obtain the Oneplus 5 before the announcement. This increases the risk that one gets biased (subconscious). It's very disappointing that so many reviewers accepted this. Reminds me of amazon reviews where often reviewers got a free product in order to review it...

obviously you accept a review unit before announcement, this way the readers get to see the review sooner...what would be the point in rejecting the unit and getting one a couple of weeks later?

mclaren777: DPreview would be wise to release some DNG files for us to play with.

These JPEG files are horrible!

I am working on the full review, I hope we can upload a couple of files then.

well, I agree that most of the images do look nice at smaller image sizes, let's say typical facebook size but at a pixel level they cannot compare at all with the Google Pixel, whatever way you look at it.

In reply to:

misspiggy01: is there any phone/app around that lets me manually adjust noise reduction and sharpening in jpeg mode? i dont want to shoot raw and post process my phone camera. just sharpening and noise sliders all the way to the left...

well, noise reduction and sharpening are applied after the raw data has been captured by the sensor and is being converted into a JPG file. Once the JPG is "finished" you can't adjust those parameters anymore without deteriorating the IQ. So shooting Raw is your only option if you want control over NR and sharpening.

photog4u: That portrait mode does look impressive.

well, you have to put things into perspective...compared to the equivalent features on other phones it is not bad at all.
