XHA1 color corrected to HVX

Without sarcasm, but can you compare dynamic range in these A1 post images? The CA on the A1 lens (20x versus 13x) is not that bad. Its a long lens with a small 1/3 " high density CCD sensor. I can tell you that you wan't notice CA in almost any circumstances.

If there is one thing I like on the A1 it's the 20x lens. Abberation in full wide? yes. Sharpness? Go in 1080i shoot some fine detail structure and take that home. There are goods and bads anywhere, but the lens is not one of them.
 
Hi Xray,

All i'm saying is that i clearly see A1's CA in these shots, even if they're downsized.
Maybe in other circomstanced, i'd not notice, but here, i see it in all A1 grabs.
 
this is slightly worrying actually. I notice the CA from the canon cameras seem to be much larger and more awkard in coloring that the pansonics.
 
The CA shows up in the wide end mostly with the iris fully open. Stop down a bit and it goes away.

Hi Antoine, understood, in that particular shot, I see it. I do not see it in most of the shots I make. I can live with it, all cams do have quirks, the Panys too.
 
Even the Pany's ?

Although I see a bit of CA in the shot in question I think too much emphasis is being put on it; we notice it. but the audience most likely will not.

You can make colors in camera like this:

Or like this, both uncorrected no CC:

Or minimal corrected like this:

It's in YOUR hands.

Great thread, thanks for the effort. Aside from the CA which I did not find a problem,
the issue of dynamic range however seems to be better with the HVX. If you look at the wall of the white building that is pretty bright you can see the wood paneling, its more visible with HVX, then look at the shadow under the bridge from the A1, its darker. So the A1 was not able to hold the highlights and the shadows as well as the HVX.
 
Dunno, taking the word from Adam Wilt -techno videofreak- looking at the dynamic range, he measured these max values with the Stouffer 41-step grayscale card:
XHA1 = 8.3 stops
HVX200 = 8.3 stops

The same. It all is what settings you use (HVX =8 stops for Cinelike V gamma, and 8-1/3 stops for Cinelike D gamma.) Further more shooting with a high F number (F9.5) is not best setting. You need an extra ND working with the Canon.

I always keep my eyes open, and in some circumstances like bright white lines, diagonal or in heavy contrast, some green/purple fringing CA is there, but in moving objects, generally it is no problem. To show you that it exists see here. ( Hey, I'm very open minded...)

Ohh after closer inspection I take my previous statement back, there pretty darn close.

Yes, I think so. It's like adding more green in post and some other stuff , but you can get pretty images out the A1. :happy:
