This has probably been brought up before, but, is there any image quality difference between the two? Or is it just audio?

Chris has summarized the differences here at HDVinfo.net:

To answer your specific question: no, I don't think there are any differences in the image sensors or optics. However there are a number of features which might affect the way the recorded image looks. Some of these would be black stretch, additional cinegamma setting, color correction, skin tone, etc.

Of course the other huge difference is that the Z1 will shoot in PAL mode and also 1080/50). It will also downconvert 1080i to 480/30p and 576/25p through the component connector (but not over firewire).

Having the ability to show the full frame (underscan) on the LCD and viewfinder is also a nice upgrade. All things considered, the FX1 is a great deal though if you don't need the XLR's or these other features.

Hi Jesse

There are no differences between the two cameras with regards to image sensors. As Boyd has mentioned, the Z1 does have extra tweaks which can advantageous but is not critical.

I have the fortunate advantage of having both Z1 and the FX1, the latter was my first baby. If price is your consideration then the FX1 could be your answer along with a Beachtek XLR adapter.

It might be a good idea to pop around to your nearest hire/camera store and check out the cameras

Z1U gets better images than FX1?

Great replies guys! I thank you all very much. :)

Would there be any quality advantage to using black stretch on a Z1 while shooting, rather than stretching black in post, on footage shot with a FX1?

Doing anything like that in post can really degrade the image. Black stretch is one of 3 things I like about the Z1 vs. the FX1. The other 2 are, predictably, 50i (and CF25) and balanced XLR inputs.

The only thing that is really nagging me about getting a FX1 rather than a Z1, is the lack of black stretch on the FX1. I can deal with the lack of XLR, and I'm not really looking to generate anything other than 60i, 60p and 30p.

Has using black stretch on the Z1 made for a noticible improvement in shooting weddings/receptions for anyone?

With my GY-DV300U, there is plenty of control on the amount of black stretch and I love it (but I don't know that it's worth over a grand). On the Z1, how many levels of black stretch are available, or is it basically just an on/off?

Using CT1 and Black Stretch is really cool, from what I hear, with weddings. Esp. in the dark. I haven't shot a wedding in years.

Thanks Heath. Can you tell me how much control the Z1 gives you on black stretch? Does it have several graduations of black stretch available?

Boyd Ostroff

Nope, all you can do is turn black stretch on or off by using the picture profiles. I really like it myself as it helps prevent the harsh look that video can sometimes have. I also find myself using CT1 quite a bit.

I'm a huge fan of CT2, though I am moving more and more into the CT1 arena. I know the HD100 and I think the XL H1 can do different levels of black stretch.

Having several levels of black stretch available on my GY-DV300U is something I truly appreciate in that camera.

Would anyone be interested in testing the quality of using black stretch on the Z1 to stretching black in post?

Robert M Wright

Maybe I should mention that I fully realize on-camera adjustment of black level straight from the head is going to result in better quality than adjustment in post, but I often find myself adjusting black level in post, on footage shot with cameras having no black stretch ability, because so often it can make for considerable improvement (especially if a little temporal noise reduction is gently used in conjunction).

My biggest hesitation still, in deciding between purchasing an FX1 or Z1, is whether or not the black stretch is basically worth about a grand to me.

Color Correct is great (Extract allows you to isolate specific colors, a la, red lips and dress on a woman but everything else is black and white, like SIN CITY). Going between 60i and 50i is wonderful, too.

While I watched Sin City, when they showed a hooker in "old town" with really blue eyes, toward the end of the movie, I found myself thinking, could that effect somehow maybe be worked into a wedding video gracefully. Personally, I thought it was a stunning visual effect and made the woman look very alluring.

Can you add a mic to the FX1?

Also how close to a FX1 upgrade?

Heath McKnight

You can always buy an adaptor for the FX1 to put a mic in.

Z1, Color Correct/Extract--use only memory 1 and select Phase and set it to around 30, 31 or 0.

Hi

I just don't understand how there can be no difference - since FX1 and Z1 there is a difference of 1 Lux. I did read any "clear" comments about the difference of this "1" lux - down to reality (wedding ceremony- event videography).
I also read no staright comments from pd-170/xv-2100 users that also work with these new HD models from Sony. Do you guys miss the "1 lux' compared to "2 and 3 lux" when it comes to low light events events? Or not? Or, a more straight question, if these new cameras weren't HD would you buy them to replace the VX-2100 AND pd170?


I just bought the ZU1 (arrives in few days) just because the 2 Lux (compared to the 3 lux of the fx1)

I would appreciate some clear and down to business comments.

Thanks in advance:)

I have the FX1 and VX2000. I just did a DV Challenge 5 Video. I had to shoot the VX2000 in an in office shot, night time, no lights, except light from a door way, and from the computer monitor. the FX1 had a hard time. It was an easy choice to go the VX2000 since everything was going to DV SD, or being encoded to internet download quality. You can check it out at www.makeyourfilm.net. Go to the "Proof of God" button. I did really have time to try to tweek the FX1, and I just went the easy way, so it is possible I could have gotten more from the FX1.

I don't think there is any difference in the low light abilities of the FX1 vs Z1. These lens, sensors, etc are the same. I don't know why the ratings are different, but it might have to do with how they are measured (there are different standards which can be used). The black stretch function can help you see more detail in the shadows too. It might also be the "hypergain" function on the Z1 which will let you shoot in dark places but with really noisy results which aren't going to be acceptable for most uses.

There are lots of good reasons to buy the Z1 instead of the FX1 (I have a Z1 myself), but low light responses probably isn't one of them because I don't think there's really any difference.

Boyd, when having Black Stretch "On" with the Z1, you do get a noticeable difference between the quality of footage compared to the FX1. I have both and have noticed this clearly when shooting in worse than average lighting conditions with both cams set to the same exposure/iris/gain settings. The only difference was the Z1 had Black Strecth on!

I would definitely get the HDV's as opposed to the PD170's etc. Even with the FX/Z1 being worse off as far as lux ratings are concerned, you do get better footage from the FX/Z1. This was clearly evident in a shoot I did for someone recently where they needed a second cam. Not wanting to use their cams PD or VX, I used the Z1. In a very low lit lighting at a reception, they had the cams on auto to compensate for the low light and you could CLEARLY see the graining on the LCD. With the Z1 there was nothing when set to auto. Doing a data check afterwards showed me that gain was at 13db which is quite a whack.

To be sure, I checked once captured and I was right - you could clearly see the difference. Graining on the PD footage and nothing on the Z1
