On article Light's L16 camera is in final stages of testing (300 comments in total)
In reply to:

entoman: Kudos to Light for an extremely interesting design, and I don't want to appear negative about such an innovative camera, but there many potential problems, e.g:

It can produce UP TO 52MP using a combination of sensors, but the individual sensors are only 13MP. Presumably the longer focal lengths use just one of these sensors?

The degree of precision needed in assembly and in aligning the 16 images during in-camera processing will be challenging for the manufacturers to meet, to say the least.

The 16 lenses are slightly sunken, but surely there will be a lot of flare if sunlight falls on the front of the camera, which it will in any situation when the sun is even slightly in front of the camera axis.

There are 6 sensors with the tele lens. A tele shot will be a merge of all of these, not just one.

Nephi: Please keep in mind they have not posted a single full rez image to date. All they have posted are noisy, scaled down images. If this camera can rival a DSLR and shoot 52 MP surely they post at least one sample?

Their 3 "full size" images are still only 20MP though, not 52. They could be genuine since some of the defects this tech is bound to create can be seen such as non-linear DOF on the portrait, you can see that some hair that is at a distance that's between the ear and face is more blurry than the ear is, and uneven sharpness on the "J104" landscape.

No images have any EXIF though which is shady by definition. They're all wide angle too, so no idea of what's left of the quality when you "zoom" in.

In reply to:

PortableLover: Does anyone else feel that some of those sample photos are fake? I mean, they probably have 1/2.3" sensors AT MOST due to size constraints. Sure, you could get bokeh with 150mm F2, however in 35mm terms that's 150mm / f11. Not exactly very shallow DOF numbers!

If the bokeh is achieved by software, one must keep in mind that it works sometimes and sometimes doesn't. No serious photographer wants to walk around with a camera that "might work". This has potential to be immensely fun toy, emphasis on word toy. I like the fact that someone is trying to innovate, but claiming it's 52mp and comparing it to DSLR and pricing it at $1,700 are three big strikes in my book.

Bokeh would come from the "long lens" sensors which are focused to infinity, and are thus a bit blurry at subject distance. It's the focus-stacking-like technique that would hopefully blend the sharp subject from wide lens sensors onto the blurry background from the tele ones, most likely indeed with added software blurring.

Whether the result meets expectations remains to be seen of course.

Kilrah: Bleh. I've preordered/deposited a year and a half ago but really hesitating about giiving up...

Yes I did, and that's why I'm wondering whether I should click that button or not...
Frankly it would be nothing more than a curiosity for me, just because I'm interested in the tech and in seeing what it can put out in comparison to my other gear. I don't see myself carrying it around and using it everyday, especially since I already have something for that (RX10III).
I placed my deposit a year and a half ago at a time where $1300 for the fun of it was no issue, but things have changed and I'd rather put that towards something else. Especially since the deposit is refundable.
Could get it anyway and just sell it after trying, but I'm not sure it will be easy to find a buyer.

BubbleGum: Am I the only one wondering whether you can make two of these collide?

That's pèrobably the first thing everybody would try... and no, it of course doesn't let you.

In reply to:

h2k: Did anybody ever check if these drones and sites physically exist?

Yes, if while flying you go as close to the launch site as you can you can see the guys changing batteries on the drones that just landed for the next round etc, also you can see each other in flight. Not sure if it's still there as I haven't checked it out lately but during the beta there were even dogfight games, had to find the others, chase them and "shoot" at them with overlayed graphics. Worked great.
They were using Inspire 1s.

On article Throwback Thursday: Minolta's prosumer DiMAGE 7 (202 comments in total)
In reply to:

cosinaphile: the zoom on the fuji x30 at 28-115 equiv is a joy of mechanical precision, i also lament that everything in this category of fixed zoom cameras today seems to rely on unprecise telescoping power zooms unlike this minoltas mechanical zoom .... this was quite a beast , in its day ... as it happens the fuji x30 has an excellent 12 mp sensor the same size as this minolta , a 2\3 58 sq mm , which is one of the larger compact sensors , sitting below the 1 inch , but above the other enthusiest 1 1'8 1 1.7 etc sensors.

The servo zoom is the only gripe I have about my RX10III. The camera is perfectly able to cope with high action scenarios, except for the eternity it takes to change FL.

Azathothh: DNG? Who uses that?

There are as many 3rd party software supporting the proprietary files as there are that support DNGs, or maybe even more... so the probability all of them decide to disappear at the same time is non-existent.
And there's certainly a time where there will be something better than DNG, and everybody stops supporting it as well.

El Chavo: Exciting news.

Finally some new tech in sensor that will give Sony a run for its money. It is about time.

The black and white sensor alone costs more than an entire Sony top end camera.
So once the color version makes it into a camera the product would probably cost around 3 times as much as Sony's full frame cams. No "run for their money" at all, unless you're in the market for a $10k cam.

On article Grounded: GoPro recalls Karma drone (54 comments in total)
In reply to:

photo_rb: I wish GoPro had instead concentrated on a gimbal stabilization platform that could be used handheld and mounted on any make of drone.

That wouldn't fly (sorry for the pun) today anymore. Integration between the drone controls and the camera is now paramount, and you can't do that without tight coupling between the 2.

On article DJI goes portable with the Mavic Pro (161 comments in total)
In reply to:

Martinka: I feel sorry for GoPro and Karma, but that is what it's called wrong time wrong place. Karma should have come 6 months earlier.

Or you could argue it's much worse, since it's a GoPro with its useless fisheye lens.
Nobody wants fisheyed drone footage since DJI made it easy to supply rectilinear one.

Ilia Snopchenko: "It's got 32 elements in 18 groups." (slide 7)
Looks like someone was a little bit too excited while typing. :) Looks more like 23 to me (which is the same as the similar Canon lens).

Though I wonder what lens could have 32 elements - I think 23-24 is as much as we're getting in consumer products now. :)

Tht's a bit hard given that moving things in a lens requires turning things... which doesn't bode super well when the only half of them ends up in the empty.

In reply to:

Magnar W: Dpreview reporter is writing: [ ... ] which means you'll really want a grip on an a7-series camera to balance the weight well.

I have never understood why you should add more weight to the camera to balance heavy and large lenses. More weight just makes everything worse.

Keep the left hand under the lens, then there is no balance problms. Then use the right hand to operate the camera, and for some extra support. Press the camera against your forehead to get 3-point support. Also, keep the elbows close to your body.

Trying to balance the camera with a grip placed away from the balance point just seems like wasting a lot of energy to keep the combo sturdy when handheld. Everything is unbalanced.

I am using my Sony A7 like I used my film SLR cameras that was about the same size and weight, with lenses up to 400 mm + a 1.4x teleconverter. Balancing problems? Not when the camera and lens is held like they were designed for.

Yup... I have no problem shooting a 7RII + 70-400G and LA-EA3. That's long and heavy, but putting more weight on my arms with a heavier body or grip would make no sense.

Marcelobtp: Nice lens image quality. Surprised to see usable 1.4 aperture.

I have the Samyang and to me it's not usable at 1.4. Way too much PF.

In reply to:

armandino: I really think you guys need to start to put a break on your highlight and shadow recovery especially on your portrait shots. That makes really difficult to judge the lens characteristics. The pictures looks so nervous and unnatural, it does not go well with the softness of such a fast lens wide open.

If you check the RAWs they're that way out of camera. That lens seems to have very low contrast and tends to illumintate the dark OOF areas.

On article The effect of pixel size on noise (112 comments in total)

Very good article series, thanks.
One thing that I would have seen added is on the "effect of pixel count" page. The explanation and demonstration of how and why noise varies little depending on pixel count of a given size sensor "when viewed at a common output size" is perfectly valid, BUT this assumption is not really a realistic one to make as the very reason for using higher resolution cameras in practice is typically either to create a larger output or allowing to crop, and there while we'll get more detail on a higher pixel count camera the visible noise will also become greater.

It of course doesn't change anything of what you said, but would be a good explanation to add for a common scenario.
