On Calumet Oak Brook, Illinois store reopens this Sunday article (41 comments in total)

Wait...this Chaim Pikarski guy who they're quoting as the vp of c&a marketing...he ran those bait and switch online camera stores that hold your credit card hostage while they try high pressure upsell tactics on you? So, what, is he buying up legitimate distressed properties and turning out his sales tactics to new markets? I'm skeptical that this is anything but ongoing disaster.

I was kinda hoping *someone* in the m4/3 world would roll w/ a radio-based trigger, not optical

It's nice to see someone developp such a successful proof of concept. And it's nice that DPR is savvy enough about the market evolution to recognize it's importance.

andrew jansen: Mr Fartleberry, I agree.
Would we only use a filter when the camera's own dynamic range capabilities are stretched by the scene? Or because the filter offers effects that the digital darkroom cannot replicate as well?
I prefer to control my application of ND Grey filter once back in the digital darkroom thanks - at least there I can decide if a filter was called for, and in what position to place it, and how strongly to apply it.
Not to mention the optical compromise of glass in front of glass, scratches, or dust settling, and the time taken to load the filter on.
That is where Lightroom comes in.
Shoot the scene when the moment is best, and do the rest back at home.

Now I am keen to hear from anyone who can help me understand why I should still cart most or all of my old filters around with me.

Emulate this.

If the link doesn't go through...all you have to do is google ocean long exposure.

Cameras are not just for snapshots.

On Pentax K-01 preview (376 comments in total)
In reply to:

RoyGBiv: wouldn't they be able to design lenses that mount to the K-mount ring, but with their lens elements recessed into the cavity a bit, or does the electronic contacts get in the way?

The body design absolutely doesn't warrant discussion. Even as an industrial design exercise, Newson mailed it in.

Unlike most other mount standards, 7 of the 9 pins are contained *IN* the lens mount ring itself. The other two obstruct a small portion of the lower right. m4/3 contains inwards of the mount ring, inside the cavity.

I think it's possible to have a substantial portion of the lens assembly recess inward towards the sensor from the flange. That would buy back the compactness that people are discounting here. It still needs to project out to an APS-C image circle without vignetting, so it'll still be larger than m4/3. But it will be smaller than what people imagine.

On First impressions shooting with the Olympus OM-D E-M5 article (269 comments in total)

It really should have been called something like the OM-5...as if anyone would seriously conclude that they're rolling out a film camera.

From the looks of it...I'm pretty impressed with it!

Are these bokeh balls, we're looking at? That's what they remind me of.

In reply to:

sarkozy: Fuji says on the phone:
Professionals are satisfied with the X10. The Orbs are Result the sensor design and the high aperture of the lens
Many professionals use the ORBS consciously as a stylistic device - guys
this is the way . . .

"Many professionals use the ORBS consciously as a stylistic device"

Are they referring to Bokeh balls? (feel free to do a google image search folks)

JohnHoppy: The acrimony that goes down in these columns beggars belief! Some respondents are in for the kill on Olympus like Cassius and Brutus on the Ides of March! Why? How has Olympus hurt YOU? If Olympus, one of the prime innovators, folds or is subsumed into another company and their technical expertise diluted, it would be a great pity. An industry needs competition to drive forward innovation, which then benefits us, the consumers. Yes, the crooks have been caught with fingers in the till, and one hopes will be punished, but they are a handful and many good people remain to design, engineer and manufacture products a lot of us want. What some idiots here fail to understand is that if all the competition disappears and you are left with, shall we say, just Canon and Nikon, development will stagnate and prices will remain higher. Is that what you want? Be positive, for heavens sake, and stop baying for Olympus’ blood, let’s hope Olympus recovers for the good of all photographers.

a bunch of luddites angry at Oly for killing off their precious OM lenses, & of course marginalizing 4/3 lenses if not outright killing them. "What has Olympus done to you? Some people have a lot to say about that. IMO, they don't deserve the stage they get, but that opinion matters little too

On bright eyes in the Unusual Catch Light Portraits challenge (7 comments in total)
In reply to:

BitFarmer: I like the shoot very much, but after inspecting the exif data, I have a question to the author:

lyrics51, why did you chose to boost ISO to 800 instead of opening aperture from f/6.3 down to f/4 or f/2.8?

opening the aperture would have rendered one of the eyes out of focus. It in fact could have used a wee bit more DoF. Boosting ISO in this case was a slick move.

On Lytro announces Light Field Camera article (271 comments in total)

Is my understanding correct? I am under the impression that this camera's subject isolating abilities has almost *nothing* to do with it's aperture/focal-length/sensor size ratios, since it is *computing* the blur and in-focus characteristics from its angle-of-light calculations. It's abilities to render OOF & in focus characteristics are therefore (almost) solely defined by the diameter of the two furthest datapoints that contain image information on a single subject. That would therefore make the key factor the diffracting capability of the microlenses vs. the distance to the sensor.

I believe, actually, its abilities to render OOF areas are going to surprise folks who think its sensor is too small to do much subject isolation. But I also think it's limited in how much blurring it can generate. You won't be recreating ginormous bokeh balls with this thing.

It's really nice to see DPR chucking in some serious vid equipment into their newsfeeds, bcs, it gives folks a reality check that their perspective on imaging might not be the whole enchilada.

In reply to:

fmian: I've been in sales for many years now, and while I understand the criticism these cameras get, one must understand that dismissing a product that has a market is detrimental to business.
If the consumer is dumb enough to think that a bigger number means it's better, then that's their problem.
When asked, I will explain to customers about the sacrifices made to achieve such a product, and only once has someone said 'Oh... So they (marketing) are lying to us?'.
Sad really.

That's the pergorative way to put it. Their interests & tolerance for image degradation when looking at a 14mp image could just be less stringent than others, so they're quite happy w/ the resulting mix of capabilities Certainly having stellar reach is something that speaks to the layperson strongly.

In reply to:

R Ortiz: Err... Most Leicas ARE mirrorless interchangeable lens cameras.

You probably mean "viewfinderless".

The rangefinder mirror is completely dissociated with the optical path coming through the lens. As far as the exposure system is concerned...there is no mirror in a rangefinder body.

> It appears that he might be correct on the lighting of the subject...how can the top front left wing can be lit, also the back right underwing be lit with the inner underwing shadowed...by the same light..
Your assumptions about the angle of the rear wing & the front wing are simply not accurate.

The talon shadow pegs it. Low sun from photog's four oclock position. I'm surprised this was even brought into question by "an expert." Like there's a "team" at DP that gives a crap about this. Heh.
