On Lytro announces Illum light field camera news story (318 comments in total)
In reply to:

Horshack: With the advent of very fast CDAF (and CDAF/PDAF hybrid designs) plus 11fps such as on the A6000 I wonder if this technology can be acceptably replicated by using an automated focus-bracket mechanism, where the camera's processor identifies different focus subjects in the scene and brackets to each. The user can later select one of the photos for selective focus on a particular subject or the camera can create a focus-stacked composite for when deep DOF is desired.

I'm aware what Lytro does. The question is whether someone needs refocusable support for a singular instant in time or whether they can accept some time skew in between photos. My guess is that skew wouldn't be a problem for the majority of use cases.

On Sony Alpha 7S in low-light: See video at ISO 409,600 news story (236 comments in total)
In reply to:

falconeyes: People are amazed. However, this is something EVERY recent Nikon or Sony full frame camera with Sony sensor is capable of in still. Just push ISO from 6400 by 6 EV in post, apply heavy NR and downscale to video resolution.

The thing new is the missing line skipping which doesn't loose you anymore 2 EV or so in video mode. And the gradation options help overcome the limitations of the missing raw file.

None of the current Exmor-based cameras can achieve a usable 409K ISO image even at 1920x1080 with NR - they have too much High ISO read noise for this type of night scene. The D4s/D4/Df/1DX/6D, maybe.

HomoSapiensWannaBe: The fire wasn't blown out at the lowest ISO example. It still isn't blown out at the highest ISO. What is going on?

In reply to:

EOSHD: You can't judge noise levels on YouTube. Compression removes it. ISO 1600 looks worse than 25,600. There's also the matter of rolling shutter on this camera, it isn't pretty! http://www.eoshd.com/content/12631/sony-a7s-rolling-shutter-test

Many videos produced today are for youtube consumption. As for the rolling shutter, I shoot in low-light more often than I shoot in an earthquake.

That's like looking at Mona Lisa and saying "pretty good".

Sigma is putting on a clinic for how to design and manufacture exceptional and affordable lenses.

On Olympus sued for $273 million over accounting scandal news story (42 comments in total)

I wonder if the banks will accept $50 vouchers toward the purchase of an Olympus product in lieu of the $273 million, esp now that Olympus has released a workaround for shutter shock on the E-M1.

Anything short of calling the K3 the Second Coming was bound to lead to disappointment in the comment section.

Retzius: Folks will gripe and moan about a developer charging $40 a year to give them a web based app with seamless photo editing integration across platforms but then go out for dinner and blow $50 for a couple burgers and beers and think nothing of it...

True, but then again a burger doesn't keep coming back asking for more money after you've eaten it.

'S' for Sensitivity and a ribbed barrel for better tactile feel.

Mssimo: Best low light camera of all times?

@Stu5, the D4s is too fat and heavy to run circles around any camera :)

In reply to:

Absolutic: IS -4EV only at central point, similar to how Canon 6D -3EV is only at center, or at other points as well? this could make a difference.

Probably across most of the frame. The improvement in low-light CDAF sensitivity is likely because the sensor itself is much more sensitive at it's native readout resolution (due to larger pixels), and even more so at its video binned resolution, in case the latter can also be used by the A7s's CDAF system.

S-Log2 support indicates this is targeted at high-end video production. I'm guessing the price will land at $3,299.

Great. If they point the ball toward the stands we'll get to see the first mass mauling of fans in multi-angle high definition.

@pew pew, nothing in Sony's release addressed the A7r's shutter shock.

On LensRentals.com needs name for massive lens calibration tool news story (133 comments in total)

I suggested this:

Syzygizer – named after Syzygy, which relates to the alignment of celestial bodies. In this case of course it relates to the alignment of lenses :)

Great images, and the kind which don't require a byzantine back story to enjoy.
