Re: Sony NEX-FS100 Camera Test
In the fs100 video, Juan Martinez referred to the vg10 as the insides of a nex stills camera repackaged into a camcorder.

This can explain why XDCAM HD 50Mb L-GOP looks just as good as Pro Res HQ. PS As far as I am concerned, the nanoFlash still rules 8bit acquisition because you can record any frame size and frame rate at a constant quality whether it be 280Mb I-frame at 1080 24p or 720 60p. |

But, let's assume we manual focus -- which I do. Trust me. (Actually even with E-mounts you can really use AF because it's Contrast AF not Phase AF. Another thing I'll bet no one explained in these demos. And, how many even thought to ask. Bottom-line, you can hear the zoom and the aperture. You do get aperture control with A-mounts and is better than non A-mount lenses, because the other lenses have no aperture control from the camera. Old the great old lenses not only have no camera control -- they have poor aperture control. The adaptor either has a ring marked 1 2 3 4 5 6 7 or you use the lens ring. But, where is the auto-open doing focusing? Not present because there is no coupling pins from the camera to provide this function. So you open manually. Where is the auto-close to the selected aperture when you start shooting? Not possible. All this talk about using adaptors, but who has actually used them. AFAIK, I'm the only one and they -- nor the E-mounts -- work well enough in the real world to justify $6000. For a $1000 with a NEX-5, sure. But, anyone currently using an EX1 is not going to put-up with the actual operational nonsense of either the VG10 or the FS100. ==== "I shoot my ex using all 3 rings and would do the same with the fs100." With what lens?

I would say the choice between a external Prores recorder and XDCAM recorder should come down to workflow rather than image quality. Prores is smoother in a FCP edit but XDCAM requires less storage. Is the HDMI on the PMW350 and 320 not 10bit? Anyone know?

If it reminds you of your EX1 that's because the designer added the needed styling cues to make you think you were getting something more than the lens and electronics of the VG10. And of Allan Roberts is correct, you may be getting the same chip as in all NEX cameras. It simply reads 3.3 mp of binned photosites.

Re: Sony NEX-FS100 Camera Test
I don't know why you keep referring to Alan Roberts' report when soo many people have refuted his crazy math. He posited that the F3 has similar sensitivity to a 2/3" camera, therefore, their photosites are the same size - this is utterly wrong. He also says that the F3 has a cleaner signal at +6db than 0db. And throughput his paper, he provides at least 3 different numbers of pixels with different reasons behind each number.

According to Dan Keaton at Convergent Design, no camera has a 10bit HDMI output. Because 10bit HDMI connectors are so rare, I would need proof that the Atomos Ninja is even using true 10bit HDMI hardware before considering it. Same goes for the Aja Mini (although it has 10bit SDI). |

Re: Sony NEX-FS100 Camera Test
Absolutely it was a deliberate choice, they'd have made it when the these two S35 sensor cameras were coming out in parallel.
Although, I don't think 8bit/10bit will affect the thinking of those people who have been shooting on DSLRs that much, they've been living with all sorts of artifacts and lower resolution, it'll be more if the FS100 becomes a cool camera to use. The design seems very much targeted that those people. |

Of course, Allan could have made the wrong assumption, but if Sony supplied a proper set of specifications he wouldn't need to make any assumptions. Of course, he might of made a math error. The unit he tested may have been faulty. BUT, unless you get the correct information from Sony and re-run the numbers -- or find and fix the math error -- you've got nothing but an OPINION of the noise level. As I've said a hundred times, opinions are not measures. Would you fly on a new plane based upon an opinion? "Gee, that 400-foot wing sure looks strong -- lets load 500 souls and fly to China." HOW a camera feels to use can't be measured so we must fall back on opinions. But, when it comes to noise and resolution and aliasing -- there is NO NEED to rely on opinions. Do you think that when Sony writes a spec sheet on a $100,000 camera it asks a bunch of shooters to give their opinion. "OK guys, we have a range of FEELINGS -- now can we now vote on the S/N ratio. And, please convert your feelings to dB because NASA really likes dBs. We can't have a spec sheet reading `looks really clean' to 9 out of 10 of us." Sony not only makes measures, it replicates these measures. It also follows a DEFINED procedure. And, during production it tests each unit to be sure it meets it specs. Do you really think Sony has a guy who looks at each unit? "Sure looks about like the one I saw 9 months ago it the lab, I'll sign-off." Let's get real. What if someone next to the guy who says "Gee, that 400-foot wing sure looks strong -- lets load 500 souls and fly to China." says "Bet you $1000 the wings won't break-off until after at least 10 trips." Now, what do you do? Get another opinion? And, if the next guy, who admits he owns stock in the company, yells for the first two guys to shut-up." Everyone who finds fault with Allan's measures has an "investment" in not wanting the numbers to say anything negative. Allan, on the other hand, has no investment in ANY camera, He simply tests them. Each one gets tested like the last one following a procedure accepted by the BBC. He runs the numbers and publishes them. The BBC is free to use the numbers or not use the numbers. They make a decision based on whatever they want. You are free to do the same. The one thing you can't do until you run a set of tests is make the numbers go away. Folks can scream at Allan. But, until another set of tests are run following industry accepted procedures -- you all have nada. PS1: Some idiot posted that the BBC should not let one engineer dictate what cameras can be used. He wanted some "creative types" to be in on the decision. So, let's assume the BBC brings in Nigel who, if I remember right, hated how the FS100 FELT. He damns a camera. Do you demand the BBC replace him with someone who is less picky? PS2: this drama has played-out over the years. In the end, when others make measures, they confirm Allan. But, after the confirmation, there's a statement about how it doesn't really look as bad as the numbers imply. That's fine. Only with the FS100 are folks screaming at those who give negative comments. Hmmm.

Re: Sony NEX-FS100 Camera Test
Alan Roberts' assumption seems to be based on an ISO of 800, which is a rating similar to that of the Alexa and Epic, which do have rather different pixel counts.

Re: Sony NEX-FS100 Camera Test
I've honestly been trying to talk myself into buying the FS since it's been shown. I guess I have become accustomed to the "EX look" Even in the latest samples I still see a something that sits wrong with me. I wonder if it has something to do with AVCHD? The colors do remind me of my SR11 which also uses AVCHD. Perhaps the reason I seem to respond so strongly to the F3 video is because it is so similar to the EX1/3?
I don't know. I kinda give up on trying to figure it out.

Re: Sony NEX-FS100 Camera Test
My idea of a perfect camera would be an EX1 style camera with this chip at about the same price as an EX1. Could have made it at about the same cost as an EX1 and saved money in manufacturing by selling it without lens. A perfect opportunity to have cleaned up at the EX1 price level. Personally I would have bought the new version and kept both. The EX1 for greenscreen and run and gun and the new version for creative film making.
I can see financially this makes good business sense for Sony as this caters for the professionals and the indie film maker and clearly keeping the two apart maximising profit and unfortuneatly keeping the indie film makers in said category. I will drool over the F3 and hope some manufacturer makes something with as good a sensor and ten bit out. From what I understand and I may be wrong is that they have to spend money to downgrade to 8bits. How sad is that if true. Needless to say I won't be buying the FS100 .with its lower res and 8 bit out with avch recording. Like Erik I was looking forward to this camera only to now feel disapointed. |
