EX 1 lens 35 mm equivalent and control q’s

[Randy Strome]

…Also no push auto focus or manual focus on any of these. I really enjoyed that on my old varizoom through Lanc. Is this not possible for this cam?

[Ray Palmer]

Call me when it comes in. I want to see it too.

Look at the tenth photo from the top. And yes, any 8 pin connector should work (maybe). I don’t really see room for a threaded rind. Write to Simon and ask him what he thinks.

[Steve Wargo] ” don’t really see room for a threaded rind.” If only I knew what a “rind” is. I wonder if it might be something like a “ring”.

Any thoughts on the crop factor?

720 is a pretty significant crop of the full sensor size. That has the image reduced to the very center of the image circle (and the sharpest portion of the lens). So for distant subjects that might be quick moving (i.e. sports), and seeing as that true 60P is only available in that reduced resolution, it would be nice to know what the 35 mm equivalent is (or what the muliplier is for all of the resolutions). Any thoughts?

My guess is that there is no crop. It resizes. It uses the full sensor but records in a 720p format.

[Randy Strome]

I wonder. That would seem tricky, as the SP mode, for instance, has a different aspect ratio, and could not really use the full width of the sensor. That alone would change the FOV. 720 and 1080 have the same aspect ratio, but I wonder how the downres is accomplished.

Thanks!

Probably by the same method the camera uses when it down-converts to HDV on the fly via the iLINK port. This is also a setting available from the menu.

Thanks for the response. I inquired to Sony, but they did not know, were going to look into it, but have not responded yet. When someone gets their hands on one a quick test will tell. Compose a shot with an object at the perimeter of the frame at full res. Reshoot at the two reduced resolution options. Check the footage to see if the perimeter objects are present or have been cropped out. The viewfinder will not nescesarily tell the story, so it would need to be from the recorded footage.

I can see that 720 could posssible be a down-convert, but I could not see how 1440 could. That seems like it would certainly be a 25% crop. So at the very least it seems that the camera is offereing two diferent fields of view (straight out of the camera).

Sony has stated that the reason they wanted the EX1 to have 1440×1080 capability is to seamlessly dovetail with the rest of the present XDCAM HD product line. That way you can have F350 footage and EX1 footage in the same editing timeline and don’t have to worry about conforming one to match the other.
