Canon XH series -- various sample clips
 
I am just a newbie here, but as I had the chance to make a direct comparison between a A1 and a Sony FX-7, I thought I should post some of my unscientific observations. After all, the question "which is one is better in low light?" is asked regularly.

First disclaimer: I am in PAL land, so those were PAL models.

Second disclaimer: this is an unscientific test.

The test was very simple: I tried both cameras in a very low light setting and examined the noise on a monitor. The light was turned down until the cameras were reaching maximum gain (18 dB, the A1 can turn the gain even higher, but will not do this automatically) and the picture was examined. This is an important test for what I will be using this camera for (filming live jazz gigs).

A few things are striking:

-first: the noise is different, you get more gritting luminance noise on the Canon and some blotchy chrominance noise on the Sony. At first sight, the Sony noise looks less obvious, but this is a question of taste.

-second: Sony automatically switches some kind of noise resolution on, while Canon does not. The picture from the FX-7 gets a bit less sharp when gain is increased.

-last but not least: the FX-7 is noticeably less sensitive than the A1. From 20 years of photography practice, I would say about a full stop less sensitive: the image is underexposed while the Canon still shows detail, you lose details in the shadows long before the Canon, etc. No surprise here: the chip is smaller.


That is about the extend of the observations. Now if someone can do a more scientific test, measure the actual sensitivity of the cameras and post pictures, I would be delighted, but characterizing the two cameras is more difficult than it seems. One can't compare one to the other without also comparing the noise, which is very different. The Sony is also obviously designed as consumer model, with higher contrast, higher sharpening, automatic noise reduction and the loss in dynamic which results of that choice. Sony's noise reduction appears to be very clever: the loss in resolution is minimal. The A1 can be tweaked to do lots of things, but apparently needs to be tweaked. Still: I chose the A1, because of the higher base sensitivity, which is important for me.

But the Sony is also a nice camera: smaller (the Canon is about the size of the FX-1) and lighter. I also liked the way the Sony always displayed the aperture, speed and gain at the bottom of the screen (they are also easier to set up) and the bigger external screen.

How do you like the other handling options of the fx7 compared to the A1? Images tweakability and external manual control buttons and such? And maybe your opinion of colour difference between the two.

That is difficult to answer. I am used to a Sony camera, so I could find my way on the Sony easily. OTOH, the Canon has lots of buttons which to me look as if they are spread around the case without any system... your mileage may vary.

As to tweakability and color, the Sony has more "punch" out of the box and the Canon produces images which are easier to improve in post. But there is one major difference: the Canon has custom controls to tweak the picture and give about any kind of color look you like, while you need to choose the VX1 (the "pro" version of the FX7) to get the same amount of control.

Two Sequences
 
The first sequence http://www.dvinfo.net/conf/showthread.php?t=81457
is a clip used for a discussion about presets here
http://www.dvinfo.net/conf/showthread.php?t=81457

the beginning is the comparison between adapted presets. It transitions into the preset I like. Of which I am looking for opinions on as far as colors go.

The second is my very first sequence ever, http://www.jaystebbins.com/movies/thefirstclips.mov shot with the Panalook preset...

Please right click and download....

Thanks,
Jay

I would like the color boost somewhere between the two settings personally. Seems that is what it might have actually looked like. What is the "squiggily" thing going on as you pan across the hull of the boat from right to left. Is that a common byproduct of video or MPG artifact?

Beautiful shots by the way.

Jay Stebbins December 12th, 2006 08:22 AM

Thanks,

I think the jiggly thing, might be the image stabilizer, as I forgot to turn it off. I found a couple of references last night mentioning that the OIS would cause a disruption during slow pans on a tripod. I agree with you on the boost as well. Last night I tweaked the settings, and added the HDF setting as well. I am headed down to the same spot today as the light is the same today as yesterday.

Thanks again,
Jay

Nice video quality. I was just filming ice 2 weekends ago in North Georgia, USA. Images looked really good considering compression. I was particulary looking for any pulsing of the stationary rocks with fast moving water in the scene that was described in another thread but didn't see any. Nice golden natural lighting.

Regards,

Raymond Toussaint December 19th, 2006 05:21 PM

Thanks for sharing Poppe! It is real winter over there, but for Finland it is mild I think? No sign of problems in the moving waterstream and black rocks, its fluid.

Yes, the mpeg compression really has improved since early days. A1 seems to be a good camcorder for shooting nature. Of course there are still some softness in wide shots, but for the money this is just great cam!

This Dec there has been only few cold days in southern Finland. I just took (and shoot) advantage of these couple of freezing days, but now it seems that we won't have white Christmas, temperature has risen again.

Nathan Brendan Masters December 29th, 2006 10:11 PM

It's amazing stuff. I really like the footage. I can't wait until I get this camera. I'm hoping to get it soon. Those close ups are nothing short of amazing, particularly at this price point.

Birmingham Alabama Noob footage
 
Ok, so the link is below... But I have to subtitle it a little before everyone is like "Why the freak did you do that...?"

I had the camera for about 24 hours or so and it was really my first thing I tried to shoot on the new cam... So middle of the night + new camera + tons of settings + A Noob = Not the best possible product

Some of the shots I slowed down and shouldn't have... Oh yeah and its SUPER COMPRESSED MP4... So that being said... I think really this probably the worst case scenario for this camera in terms of quality...

Oh yeah, and I only did about 13 minutes worth of total filming and edited it in about 3 - 4 hours...

Looks pretty good for only having the camera for one day. Now I know my way around Birmingham. Someone should call the fire department, there's a flaming pole in the city.

Nathan Brendan Masters January 5th, 2007 03:39 PM

I don't know, putting the flame out of what is apparently an eternal flaming pole may not be a good idea. Might release havoc on the city. I love the footage. What's great about this footage is when you think of Southern cities you really don't seem them as the big cities they are. These aren't small towns. They have skyscrapers and thriving metropolis setting. I'm loving the songs you guys are picking. (Most of these I've never heard). Thanks for letting the song play out.

Macro Footage
 
I found an old 10+ macro I had laying around and decided to have some fun with my precious A1. Here's the footage:

Pretty nice for a cheap macro. The yellow CA it gives is actually quite nice in this context...

got it.. nice

an old macro.. but that fixed to the ring screwing it?

CP test
 
Tried to use all the CP on the camera and the ones posted here on a end of a sunny day.

Jeff Nelson January 14th, 2007 07:34 PM

Thank you, that was interesting.

May I suggest that next time you do this, just cut from the same shot (like the wide shot) one Custom Preset after another, don't have the # scroll across the screen but just in one place, then we can scroll through the footage getting a direct comparison between each setting, seeing the same shot, then do all the closeups together the same way. Just makes it easier to really compare.

Appreciate your taking time to demo this. I still like 17 & 18 the most in your test.

Stefano Folgaria January 15th, 2007 04:36 AM

Put another way to see the test, 8 camera presets in a single window, but for better viewing some HD files here in different sizes (ASAP): http://www.stefanofolgaria.it/test/allHD_1080p.mov

My first short on the A1
 
Hey everyone. I just recently shot an short in Arabic, but it's subbed so no worries. It's around 6:30mins long.

Link: http://www.youtube.com/watch?v=pSLPm_v9aSE

I have a feeling that I'm not getting the best picture. I'm not sure if you can tell since this is youtube quality, but I do feel that something is off. I'm really hoping for some tips.

Oh, the movie is called The Last Bahraini. Bahrain is a small island in the Middle East and the movie is about a thief who attempts to steal a watch from an "inferior" Indian taxi driver. You see, locals in the Arabian Gulf some locals see themselves as superior to people from the subcontinent.

Err... Yeah, I just wanted to explain that to make the movie more understandable to the non-Arabs in the forums, which is pretty much almost everyone here. =)

Enjoy.

Doug Tessler January 20th, 2007 09:57 PM

Excellent work
 
Looks like it was a little dark though, maybe utube problems

Great Job
Doug

Music was good too

Estebe Verde January 21st, 2007 01:17 PM

Nice!!!

I liked it. The story always has and always be the sine qua non. The technology you use to tell it is merely a conduit.

For You Tube it looked great. You are well on your way man. Putting it down is the biggest step. Tweaking your image to your liking just gives you finer control over your message.

Farid Alkhajah January 21st, 2007 03:26 PM

Yeah, I definately agree that story is key. Yet, I'm still trying to get the best out of my camera. I recently downloaded some New York at night footage from on here and I was amazed at what the A1 can do. It's probably just New York being photogenic though, but I just want to make sure.

Noob question: By the way, I edit on Premiere Pro 2.0. If I plainly just export as an AVI file, will it technically be HD?

It goes way way way beyond racism. There is also tribalism, clanism, and issues of fatherhood even within families.

The Arab world and the Gulf States in particular are as diverse as anyplace on earth.
Yup, got that right.

I think that's because I've been screwing around with the presets a bit too much. =p

Oh, are you here too...

Nice pics Rumi
You mentioned that the colors were a bit flat, haven't any of the presets solved that issue?

Joni

Rumi Geiger January 30th, 2007 06:21 PM

Hi Joni, here tooooo. hee heee.

Well you can adjust the colors a lot. I just like how the HVX produces rich greens.

Best to you friend.

DOF usable with A1!
 
1 Attachment(s)
Of course, the clip doesn't show the full potential of DOF manipulation (just a casual shot; no ND engaged/shutther speed increased in order to open up aperture, etc.) - but clearly better than what I could get with my previous cameras, especially the V1!

BTW. Is it normal that - with AWB on - the white window frame gets pinkish from the red flower? When I removed the flower, the AWB reset itself back so that the frame was perfectly white again!

Tom Hardwick February 3rd, 2007 09:36 AM

The V1 has a greater telephoto (35 mm equivalent) than the Canon A1, but of course that Sony lens feeds smaller chips. The V1 is f/2.8 at full telephoto, whereas the Canon is nearly a stop slower, so on balance I'd say the two cameras were neck and neck in the shallow dof stakes.

tom.

Piotr Wozniacki February 3rd, 2007 09:41 AM

Tom, you're right of course - but in practical terms, shooting from a distance long enough to engage the telephoto side of the lens can be the most difficult of all measures, shallowing dof.

Joan Manzaneque February 6th, 2007 07:00 AM

Some B&W footage
 
Hi everyone!
I'm new here. I just bought my Canon XHA1 a couple of days ago and I thought that maybe someone would be interested in see how the B&W preset from the Library looks like. The clip is not great but I hope it helps. Sorry but it goes out of focus once or twice.

You have some nice footage there. The neon lights against the sky at dusk is really beautiful.

Stefano Folgaria February 19th, 2007 06:32 AM

nice colors, but the format is wrong.
you exported in a NTSC format 720x480 without anamorphic options, so the image is distorted.
