On Canon EOS 7D Mark II First Impressions Review preview (2702 comments in total)

Quite hard to pick up the winner of IQ. Sony seems sharper feathers (lfeft lower corner) at low iso (RAW), while Canon may have a tad lower resolution at 6400 based on a hair sample on the middle right (RAW). Nikon has sharper black-white circles at the left lower corner, iso100, raw. Pentax may have problems with its lens there, while sony's lens really shines. Sony's RAW high-ISO noise may be slightly "brighter" that others', but all cameras have quite similar chroma noise pattern.

IMHO, other features, lens and accessory prices and camera price itself (current and in the future when you want to replace it) are now more important that IQ-differences.

Paul JM: Erez, a couple of comments refer to the 'DR' of the A7, but surely there is some HDR action going on in post here ?

If HDR, the effect is kept subtle, nothing like those typical "old rusted car" HDR-photos.

Maybe next version will have narrower bezel. Top and bottom are quite wide. I would rather see those areas occupied by a larger screen.

On More manual control on iOS with Manual Cam post (46 comments in total)

Why Android is always behind? Manual controls should have been there in phone cameras from day one for those who need them.

AbrasiveReducer: This was inevitable. Everything else is automatic so why not? The next thing will be a true program mode. Just set it to "wedding", "landscape", "portrait", "over saturated for Flickr", "HDR max" and so on.

You push the button (if you insist.) We do the rest.

Well if the camera was installed under a quad-copter, it could relocate itself to right position and take a photo completely autonomously. It would recognize some keywords (eg. in wedding ceremony) and act accordingly. Where would a photographer needed anymore? :)

If you just keep Oppo's camera pointing forward when not taking selfies, you'd be fine.

Zeisschen: 100% copied design, congratulations...

The components (screen, cameras, internal circuits etc.) have become so standard, that no wonder if cellular phones look similar.
Xiaomi's price is good. Hopefully others will follow.

In reply to:

Preternatural Stuff: Ditto what some have already pointed out. The difference will be huge in video. Someday somebody will make a consumer grade full frame 1080P video cam with exactly 1920 x 1080 pixels on the sensor. Or 4K video with only 4,096 x 2,160 pixels on the sensor.

Until then, this is the closest you can get.

I can imagine bringing both the A7R and A7S for work or travel. The former for daytime outdoor shoots and the latter for indoor/night time shoots and video. What a combo. It'll be like the old days when different film bodies were loaded with different speed film.

In good light, Foveon might work with exact 1920x1080 for FullHD, but Bayer-sensors don't have the full resolution their pixel count may indicate since the values for all R, G and B are obtained by interpolation from neigboring pixels, so their resolution should be higher, ideally 2x.

On Nikon D810: What You Need to Know article (142 comments in total)

Has enyone figured out, what specifically Nikon means when that say D800E has effects of AA filter 'canceled', while 810 has it entirely left out? What is the difference between the two cameras?

In reply to:

jenbenn: What you forgot to mention is that the 5D has vastly superior dynamic range in all shots. The highlights in the sony raws are all blown out while the canon retains considerably more detail.

BTW I own a 5d III and a Sony A7 (non-r). The canon consistantly delivers less noise and better dynamic range at all isos above 400. The exception being at iso 100 and iso200 where the sony has less shadow noise if you need to lift the shadows dramatically.

To complete this: Any test site (hint: DXO) rating the canon sensor far below the sony sensor, should start using their cameras to take photos instead of performing absurd measurebating tests which do not translate into real life.

Most blown highlights look similar on both cameras, but the white arches on the upper left side of the building in the middle do have creamy color in Canon, while totally white in Sony pic. Also, the yellow object inside the building in the middle has deeper color with Canon than with Sony. Of course that is, if lighting has been similar on all shots and is not varying.

On LG releases G3 with QHD screen and laser-AF post (60 comments in total)
In reply to:

Photog74: I wonder what the point of a 534ppi display is. Most people's eyes cannot resolve more than 300. And even the eagle-eyed cannot distinguish more than around 400 dots/pixels per inch, really.

Maybe screen resolution is the area where tehcnological progress is easiest/cheapest made at the moment. Battery capasity cannot increased without extra weight/size. Processor power/energy consumption is up how fast Qualcomm get their Snapdragon 805 to the market. So far the phone manufacturers have to settle to Q's older processor 801. On the camera side, more and more companies are tied to progress made by Sony.

Quite nice looking phone. Top and bottom bezels are relatively thin, unlike in HTC's latest model, where company logo takes space.

What I'm missing in most phones is some sort of optical zoom. I guess that would make the lens system too thick, unfortunately.

On DxOMark recommends best lenses for the Nikon D800E article (72 comments in total)
In reply to:

JKP: I have been looking for an affordable WA lens for Canon EOS 6D, and it looks like Samyang 14mm f/2.8 IF ED UMC Aspherical would be a good deal. At about 250€ (inc VAT) the sharpness/price ratio is excellent, as again shown also with Nikon D800E body by DxO.

Thanks for the hint, need to read the 6D test. To my understanding, It really shouldn't matter what camera is behind the lens when it comes to sharpness of a lens, unless their EOS-mount is somehow fundamentally faulty, flimsy or smthg.. Likely a bad copy as you said.

Thanks! It worked. The grearshop thing was all new to me, last time I tried to change email address about a year ago, it said the address would be changed after they receive confirmation email from the old email, I think.

My original email address doesn't even exist anymore, but there is no way I could change that, except by creating a new DP account. Which I don't want. So no email notifications for me...

Running Retina MacBookPro here with Win7/64bit via bootcamp. Like the combination of Apple hw + MS sw a lot.

Very reliable, not a single crash happened so far.
