On article OPPO to announce 5x zoom smartphone technology at MWC (62 comments in total)
In reply to:

Zoom Zoom Zoom: Something like this is the way to go:

https://www.asus.com/us/Phone/ZenFone-Zoom-ZX551ML/

This is where the new Oppo will probably be like, as Asus left off with a groundbreaking zoom design (including OIS which is really a feat) on a phone with an absurdly bad sensor than no one bought. Oppo is probably betting that most people don't know about the Asus Zoom Phone and surely will make it slimmer, longer zoom range and use a better sensor. There will be no revolution.. Asus did it already and screw-up as they always do. Most people don't know but Oppo is the largest phone manufacturer in China, a huge company ahead of Xiaomi, ZTE, Huawei, Vivo & all other Chinese dudes. If someone has the R&D and manufacturing capabilities to do this right, it's them for sure.

This properly done could kill off everyone else including the iPhone and all look pre-historic. The problem is no one can make such zoom lens with a fast aperture, so it will be a low light disaster. That's the real issue..

no, the OPPO solution HAS to be more clever than this...the problem with the Asus and similar designs are the slow apertures and they are unavoidable if you want to keep the device relatively slim.

In reply to:

Zoom Zoom Zoom: Where is this news??? The Asus Zoom Phone did this 2 years ago already with a superslim phone without any unusually big camera protrusion and enclosing a 3x zoom inside. The ONLY reason it failed on sales is that they equipped the phone with an absolutely horrid and dated sensor and the photos were all crap! It only would take them to make the same phone with a good sensor to be a success. Why Asus never updated the phone is a mystery to me, then again, it's a company that I never understood and that only releases half baked products.. blows my mind how anyone would ever buy anything from Asus aside from motherboards which is the only thing they do well. From laptops to phones, I am yet to see ONE Asus product that is a finished concept or actually works well. So most likely is what Oppo will do, is just picking up where Asus left off, making a phone with a slightly longer zoom range within the same zoom lens design, and equipping it with something less than a mediocre sensor to match.

the images on the Asus Zenfone Zoom weren't bad because of the sensor, they were bad because of the slower apertures any conventional zoom lens comes with. I am pretty sure OPPO are going to come up with something slightly more clever.

Edgar_in_Indy: I didn't realize OPPO made anything other than high-end Blu-ray players. They seem to be a good company, unusually responsive to customer feedback feature requests for their Blu-ray players (I own one).

interesting, I'd never hear of their Blue-ray players ;)

In reply to:

ottonis: I would't hold my breath. Hasselblad made an add-on module with 3x zoom for the Motorola Z, but the lens was very slow, some f/3.5-5.6ish. Add this to a tiny 1/3" sensor. That's maybe good enough for sunny beaches and mointains at noon, but any other scenario of available light will be beyond the capabilities of this add on zoom module.
Oppo did either invent some disruptive new optoelectronic technology or this 5x zoom is going to be slow as hell.

the Hasselblad is 10x zoom and has a 1/2.3" sensor, it is on the same level as a compact camera with the same specs.

sirhawkeye64: I thought that it was proven (just like with fingerprints) that face recognition (and thus, probably a 3D recognition system) can be duped and bypassed with an accurate 3D representation or possibly even a picture.

well, a picture would be 2-dimensional, so I'd assume it would not be able to dupe a 3D-system :)

DualSystemGuy: Laptops have had this for a long time now, it's easy to fool.

When did DPR turn into a cell phone rumors site?

this is 3D-recognition, with a laser, not a camera....are you sure this is on laptops?

In reply to:

WillWeaverRVA: I'm gonna buck the developing trend here and actually say something positive about this phone. The IQ from this phone's camera is actually pretty good for a smartphone camera. I'm impressed with the panoramas and the sharpness of the developed RAW images. I personally wouldn't shell out the cash for it, but it really isn't that bad, honestly. (Of course, I do wonder what the images would be like if it DID have a larger sensor...)

it's a nice device indeed, looking forward to test the Mate 9 which supposedly has an even better camera

ottonis: First of all, thanks to Lars Rehm and dpreview for this nice and useful review.

It is just incredible how Huawei managed to let the combined output of two sensors perform worse than competitors' mobile cameras sporting only one single sensor. What a waste of resources. One would have expected a dual sensor setup to deliver twice as much SNR, half the noise and higher dynamic range, but they did't deliver. I was so excited about this promising dual sensor approach and anxious to read the reviews, now I am quite disappointed. I truly hope that future iterations of the dual sensor concept will work better than that. They really should.
Moreover, I wonder why they used a max aperture of only f/2.2 whereas other manufactureres have alerady reached f/1.8. That's more than half a stop of light....

yes, F2.2 is slower than most but then they combine the light captured by two lenses...still a valid question though, the camera could be even better with faster lenses.

Marksphoto: when i saw 2 cameras, I got super excited, I thought... finally I will be able to shoot 3d..

I was so wrong :( Nothing special about this phone other than a gimmicky idea

3D cameras were around a few years ago and never got any traction in the market...probably for a reason ;)

In reply to:

Antoneeo: I bought this phone 2 weeks ago. Unfortunately it is well below my expectation. Before this I had (and still own) a Samsung Galaxy Note 3. To be honest the bigger problem is that it misses the focus too often even in bright light. This carries to out of focus images. Sometime they are just slightly out of focus, some other they completely miss the focus. This is not acceptable by a phone at this level. I will sell it on ebay and save the money for the Galaxy Note 7...
To be clear, the few times that the focus is ok the pictures are really good. But to me this issue is too much annoying. This morning I went out with some friends and took a lot of pictures. They are 50% out of focus. The phone itself is great, nice HW, materials, shape and performances. But for me the camera department is the most important so.. I will go back to my reliable Note 3 until the Note 7 drops in price.

sounds like a bad copy, I had no trouble in my review with focusing

WestO: I believe Apple will "invent" the P9 DOF feature in the iPhone 7 next week ;). Once Apple does, everyone will trip over themselves to get the revolutionary tech. Shortly after, masses of hipsters will throw out their DSLRs.

well, they did a dual-cam but a slightly different concept :)

digitalhecht: In all fairness to their readers, might I suggest ALL blogs that feature new products place the applicable crowdsourcing, er, source all in caps at the start of the article?
Something like:
"From KICKSTARTER/INDIEGOGO -"

It is actually mentioned in the summary text on the front page that this is an Indiegogo campaign...if you are not interested in crowd funding projects you would not even have had to open this article...

On article OnePlus 3T camera review (96 comments in total)
In reply to:

backstreetrover: This review does not address the biggest problem with the camera - you cannot take pictures of moving people , dogs etc indoors (and even sometimes outdoors). The moving objects will come out blurred. The shutter speed is consistently below 1/20 even with reasonable lighting. OIS prevents camera shake, but most people use a smartphone camera for taking pics of their kids, family etc. You can'get get a good picture as the slightest motion of the object will result in a blurred photo. Going to manual mode and setting shutter at around 1/60 fixes this, but who will go to manual mode and play with settings each time they need to shoot a picture?
I wish they had used a 12 megapixel sensor as they would have got larger pixels, and the phone wouldn't have to reduce shutter speed to get the same exposure.

I seriously did not notice the OnePlus to be any worse in my test than all the others and looking at the shutter speeds they look pretty normal for the respective conditions they were used in. I think what is suggested further above in this thread might be the problem: if you have HQ or HDR (especially the latter) activated and shoot in lower light there is an increased chance of ending up with motion blur on living subjects, so make sure you've got those turned off when shooting scenes with motion.
