tkbslc: I always thought 4K was a long way off, but just yesterday I saw a lower end TV manufacturer (Seiki SE39UY04) offering a $700 40" 4K (@30Hz) TV. 30Hz is low, but it matches the 30fps max of the Black Magic 4K camera.

When lower end manufacturers start offering $700 4K TVs, you think maybe the higher end brands won't be out of reach for long.

I saw this too. For games, 30Hz is low.

However, most movies are still 24fps, so 30Hz is actually more than you need, and it will be under that for watching films.

The HFR version of the Hobbit strongly illustrates that 48fps video is not most people's cup of tea. Resolution, however, will dazzle the eye without giving you a headache.

This doesn't guarantee sharpness, since the compression schemes and levels vary, even within the same site. Pictures that are very red are destroyed by whatever facebook is using for compression. Causes major macro blocking and destroys detail.

Math. Why are people so bad at it?

This works. You get more light, less dof, and more angle of view with it than without it. End of story.

If you aren't going to shoot another format, don't worry your poor little head about comparing it.

nathanleebush: Can someone who's not terrible at math like me give me a rough estimate of what kind of equivalency this would translate to on a Super-16 sensored Blackmagic Pocket Camera (M43 mount)? Would it essentially make the field of view like an APS-C camera?

Total conversion to m43 is 1.4x

...so something longer than that? I've read it's about a 3x. So for a 14mm lens figure 14x3x0.7 = 29.4mm? Sigma 8-16 starts to sound more attractive, eh? If you need to shoot that wide, that is.

In reply to:

HowaboutRAW: In mirrorless, no Leica Ms, nor the Samsung NX300. Kinda of missing some good lenses there DPR.

The new M should probably be in both categories. Other than AF, it's identical in features to the m43 and Nex systems.

GURL: "The additional light capture from the clear pixels offers improved low-light performance but also allows the use of shorter exposures the rest of the time"

Said shorter exposures should result in deteriorated SNR for red and blue signals. As I suspect that color accuracy in the darkest parts of an image don't really matter this should not be a problem (our eyes don't see the difference?)

What about making the R&B photosites larger to compensate? That could be a win/win.

I'm not seeing that "improvement" in the raw files. Looks worse to me. Anybody else seeing that too?

In reply to:

Jimmy jang Boo: "..., click through to see how the Q7 stacks against the competition."

What competition? There's nothing quite like the Q.

...it's front focused. Look at marks on the paper in the foreground. It's subtle, since DOF is so big with these cameras, but it's there. Dunno if this is an issue of the testing or the camera misfocusing, but that's definitely the issue. Do over!

Two things: there appears to be a bit of front focus to the Q7 shots. And the raw file links are broken.

Trollshavethebestcandy: M43 size

Good job.

@T3: of course it'll sell! It's their cheapest model! And it'll probably be on a deep discount by xmas. Watch it fly off the shelves and half off! But that doesn't make it good gear.

On Nikon issues firmware update for D7100 article (20 comments in total)
In reply to:

Aris25: No metering in video mode!!!!!!!!!!!!! At least give us that!!!!! This is rediculous!!!! We cannot change aperture in video mode, we can't see if the exposure is right cause we dont have metering in video mode, we can't use flatter picture profiles because of banding and fpn .... But we have headphone jack with live meters for audio, and mic input for clean audio recording!!!! Does anyone in Nikon Tests the versatility in video mode before they put it in production... The D7100 its an amazing stills camera but for video... i dont think so... The picture quality overall isn't that bad if you have the time to denoise the footage(sometimes and in the lowest iso)... and if you have the time to exit from live view to change the aperture ... and then to check how is your exposure ... and then come back to live view ("ohhh the white t-shirt is overexposed") Then you have to exit from live view.........Nikon Rulessssss

AIS lenses focus marvelously for video. However, the click stops are distracting during video. It's not an elegant solution. I tend to use my Panasonic cams for video, since the adapters (and I'm using dirt cheap ones) adjust aperture more smoothly. On auto shutter/ISO, you can transition from light to dark in one cut and do it so it looks nice.

wootpile: This is a nice build! Anyone who has worked on big movie sets knows that without a silent blimp you simply won't get any work.

A V1 won't cut it either - not enough resolution and high iso capability. try that once and you won't get any more work from the film studios :)

Thanks to op for offering a alternative to commercial variants!

Ok, no really, with all these comments you're coming off like a Fuji evangelist. That appearance is actually the opposite of convincing--it's disconcerting.

LaFonte: I used x100 on a movie sets. Resolution was there and it is silent (only lack of zoom, but that may not be a problem in small sets)
But kudos to the pelican solution. I always enjoy a good DIY, definitely smart.

No, I get that--6mp is more than most customers actually need. 12 is really enough for a billboard--that was proved years ago.

The XTrans resolution is actually lower than rated. If you can sell it to your clients as enough, then cool.

What you say is all true. However it is also true that professionalism makes a big difference. Demonstrating competence is something you have to do 24/7, as your rep relies on it. You're not going to win any hearts when you end up taking more time to get the shot than the DP, because your camera can't nail focus. I do wonder if that will be an issue in the future as light levels drop to normal real world levels for the new digital gear. What if a DP wants to shoot by candle light? Will the Fuji AF or sensor keep up? If you have experience, please share? I know that the 51-point Nikon system is a beast and will continue to give good results under light that's far too dark for today's movie cameras.

micahmedia: I've tried this with the D700. It greatly reduces the mirror slap, but it's not silent. Not quiet enough for a quiet set or quiet performance. I think the issue is the soft cushioning. The Nikon bodies resonate at a low frequency. Perhaps stiffer foam would mitigate this. I never got around to more experimenting, but the basic idea is good. Not perfect, but useful.

Yes! I found that too! Unfortunately, I need something a little quieter. I need to be able to shoot next to audience members in ninja fashion.

If I find a better foam in my future experiments, I'll be sure to share!

...this isn't the type of thing DPR really ought to bring up. Unless you're hoping we can address our addictions only to accept and embrace them?

Ideal for...? With low resolution and slow focusing of the X-Pro or XE...it's just too much time wasted on missed shots. No pro would stand for it. Amateurs, fine. Not pro.

When your paycheck and reputation rely on it, you need to get the shot the first time. That's what a good DSLR can do, that a MILC can't under all circumstances. At least that's the case for the current crop of cameras. I expect this will change over time. But in the mean time, on big budget productions, blimps and DSLRs are the way.

On Just posted: Olympus Tough TG-2 iHS Review preview (106 comments in total)

I just repaired my little brothers' Stylus "Tough" 3000. Rear button design/construction was terribly flimsy. The zoom buttons were the worst, and that's what broke. They were held in place by an S-shaped plastic spring a fraction of a millimeter thick. This spring was both a locator and a return spring.

In other words, pictures something that has to swing back and forth like a car suspension. Now picture it supported by one spring and that's all. And it's positioned so that the spring twists back and forth with every press of the button. Fatigue design right in, so it fails like a paper clip bent too many times.

Now, I realize this this is a cheaper model, but still...it could be designed to be more durable with the amount and type of materials. See: goo [dot] gl/5Tefe

40daystogo: This review finds that the upper ISO performance is stellar. This review thinks that many RX100 users will want to upgrade simply for the better high ISO quality.

http://www.imaging-resource.com/PRODS/sony-rx100-ii/sony-rx100-iiA.HTM

Maybe in jpeg, but the raws they posted seem worse at top ISO.

In reply to:

Bob Israel: The previews on this camera say it all . . . improved low light performance while maintaining all the good of the original RX100. I pre-ordered one already to go with my RX1 and I just sold off the last of my m4/3 lenses. The camera will do all I need for travel purposes and give me high quality 20MP images that I'm sure I will be able to print as large as my 17" Epson printer will let me print.

Can't wait to get it!

See my post above. It seems to be the same to slightly worse at the top ISOs. I'd wait and see. Otherwise, I like the improvements...just not convinced on the sensor yet.
