Century Optic 2x & .6X adaptors for HVX compatible with EX1?

I am contemplating making the switch from HVXland to 1080p, on the barrel aperture EX1 paradise, but I am pretty well invested with the HVX. It makes me very happy to see that the EX1 is 77mm on the front end so all my screw on filters can make the transfer. Is it a pipe dream to hope that my Century Optics adaptors could work on the EX1 as well? Even my geardear mattebox too?
 
Century adapters use a bayonet system, and I doubt the bayonets are the same on the EX1 and HVX.

HVX is 82mm, EX1 is 77mm, so you'll need a step-up ring for the EX1.

Don't know about the mattebox, matteboxes are a problem on the EX1 because of the mic overhang, so you'll want to investigate that.
 
Thanks Barry,

Does a step up ring exist to make this conversion happen? Would it screw into the front threads of the EX1?

Are you convinced the EX1 is superior to the HVX overall?
 
A 77-to-82mm ring certainly exists. You can probably get one off ebay for $5.

Superior to the HVX overall? No. In some ways, yes (it's definitely noticeably sharper and with less noise, ranges from 1/2 to 1 stop more sensitive), in some ways it's inferior (no SD recording at all, it has a rolling shutter CMOS sensor, SxS is way inferior to P2 for workflow, it costs about 30% more).
 
Can you explain the difference between the ex1's rolling shutter vs the hvx's shutter? Can you not change degree of shutter and shutter speeds with the ex1?

thanks barry?
 
Basically, as I understand it, the CCD chips of the HVX200 are exposed to light all at once, providing uniform exposure. The CMOS chips of the EX1 use a "rolling shutter" which exposes the top of the frame first, them moves to the bottom of the frame.

Shutter speeds are still selectable on both, AFAIK, but the "issue" with the CMOS can be skew or wobble. During fast action, the rolling shutter may not, in some cases, be able to keep up with the action. Like your recent skier-X piece for example. Skiers coming over a jump at 60+ mph might be moving so fast through frame that the CMOS just can't keep up.

This is all theoretical to me at this point, as I've not seen any real "fast-action" footage from the EX1 yet. So, until someone points to that kind of footy…

And if I'm wrong, which is somewhat likely, I'm sure someone will be along to correct me shortly.

And here's a link to an article about CMOS vs. CCD, with more links at the bottom of the article.

SM,

thanks for the edjumaction on that. makes me think ccds are pretty cool and cmos kind of scary. we are going to be shooting out of old school russian helicopters (mi-8's) this coming summer and the wobble factor will probably be very high. hmmmmm.

Well, like I said, I've yet to see the kind of footage that you (and I) shoot captured with the EX1. It may be the best thing since sliced bread. It may look better than anyone could imagine. But the HVX is a known entity for me, and until I see, feel and work with the EX1 myself, I'm not going to switch…

yet.

Barry,

Why do you say SxS is "way inferior " to P2. I haven't worked with it yet, but I have greatly liked what I've seen about the cards and how the camera deals with them, they download faster and hold way more at 1080. I could see questioning the long GOP 4:2:0 but I don't get the SxS workflow issues.

Maybe I've missed something significant.

I think the most important thing to take away is that testing the camera (rent, borrow, steal, etc.) and using it in as close to the situation as you shoot in is the best and only way to really tell if any camera will do what you need it to do.

That said, the stuff you guys have shot on far lesser cameras is beautiful and poetic. So it's not the camera that makes the magic.
