1 more question John Knight :)

when recording on CF card avi file, is it stored as a single avi file until card is full or many avi files until card full?

Many. Each time you push the record button - it generates a new file. I know you are used to capturing one big file and then hacking away at it. But it's simple enough to import multiple files and pump them all sequentially into the timeline with a couple of clicks of the mouse.

multiple files are much better than single file i think.

is file numbering system the same as digital still camera?
the file numbers keep going up and up to thousands and thousands?
Example: 0896500 avi file

I think i like what i hear John :) you are a Sony seller now, should get some commission from them.

I'm not telling. :)

It's on Page 18 of the MRU Manual. (Which you are now going to read)

Or covered in depth in Doug's training DVD (Which you are now going to order)

Sony rule. I've been using exclusively Sony gear since the v5000 Hi8 was released in 1991. I've also got a Bravia 60" SXRD screen, and a Sony HDR-950 HDD/DVD recorder. Not once in thousands and thousands of hours recording has Sony ever let me down.

Just a quick question John to a man who knows his apertures from his audio levels. What finally decided you on the Z7 as against the EX1? Here in England the prices are so close it's a difficult decision to make, and I'd like to hear your reasoning.

I holiday'd (can you say that?) in ChCh 19 months ago. Wish I'd knocked on your door.

Hi Tom, yep, EX1 is NZ$12,000 compared to Z7 at around NZ$10,000 here.

EX1 is a beautiful beautiful machine, but not a good business choice for me.

(1) Major reason is that EX1 shoots exclusively HD. My clients view exclusively SD.
(2) My editing system would need a major upgrade to be able to handle HD 1920x1080i editing
(3) I would have to invest in some kind of XDCAM archive system. More $$$
(4) I would have to spend at least another NZ$6000 on SxS cards (which would be worth NZ$60 in a couple of years!!)
(5) I often shoot DV-CAM in the field and handover tapes to police/media. Would you hand over an SxS card?
(6) Think the Z7 is a little cumbersome to hand hold? Wait until you try the Ex1!

Easy choice.

6 bullet points that shoot it dead, thank you.

I've used an EX1 for a wedding - loved it, loved the swivelling handle, the really sharp screen and the low light capabilities. But most of all I loved the results up there on my 46" 1080 LCD.

Know what? I thought I was squeezing the last drops of quality out of my Z1 once it was burnt to DVD-R and up-scaled into this big TV. But the EX1's footage just sneered at the struggling Z1 - I was eyebrows-raised surprised by the image quality difference.

The EX1 does with ease what the Z1 struggles to attempt - that's the best way I can put it. And I just have the feeling that however good the Z7 is it's a sideways step from the Z1, when in reality most of us should be leap-frogging.

But your bullet points make sound business sense.

Judge for yourself Tom - I've put a couple of test shots on Flickr Z7 (right) v Z1 outdoor LCD test 1 on Flickr - Photo Sharing!

[Tom Hardwick]

Not quite sure what I'm seeing here. Both screens are in direct sunlight, at their default brightness settings? What's the diagonal line across the Z7's?

beneath the shadow (?) over z7´s display : The z1 display looks much brighter than z7??

The diagonal line is NOT a shadow - it is a reflection which is not apparent on the Z1 screen which is much less reflective. As detailed in the photo descriptions on Flickr, they are both in direct light hazy sunshine. In the first test both screens are set at default mid brightness, in the second test the Z7 LCD is increased to maximum brightness.

[Tom Hardwick]

Can I take it that you think the Z1's screen is better in bright sunlight than the Z7's, though not as sharp?

Better outdoors period. However much sharper the Z7 is, if I can't make out the subject the extra resolution is useless.

It's this kind of attitude that will scare people away from a forum. Think that everybody is learning here and you have to realize that before you answer.

Wow . . am I glad to hear this. I thought I was the only one that was treated that way over there. Now I know why I pretty much left. Great to read ya'all :o)

For now just commenting on this one. I think the DOF is quite narrow on this lens. I'm an old time Nikon FM2 guy and the one thing I noticed right off on this lens is that the DOF is tight on the close ups reminding me of my zooms on the old 200mm lens. Thus, when I zoom with the lens close in, I always keep my hand on the focus ring and the little finger on the iris just in case AND because of both the light change AND the tight DOF.
