Jack, they are great for doing interviews as you can get closer to the subject and use the onboard mic. Also, last year I took a small ship throught the Straights, I used it in the cabin, passageways, engine room (by the way, being able to turn the volume down is fantastic in a situation like this) and SMALL dining room/bar. I have used it at parties wedding receptions, hazardous waste sites and in back alleys. It is a really good lens to have. I never actually thought I would buy one, until I realized how often I was borrowing one. Bob Safay

I don't know how much information is out on the XL2 yet, but wont you be able to use the 3x lens on the XL2 as well as the XL1/s? Assuming they are carrying on their reputation of having a camera that can do anything and then some... ooo, i'm excited.

Rick Bravo March 3rd, 2004 11:20 PM

Great for shooting with the GlideCam V8!

3X WA Help!!
 
XL1s and Canon 3X WA
After reading so many good things about the 3X wide angle I splashed-out nearly 800 GB pounds on one, primarily to use for shooting property interiors. My question is, how do you get a crisp, well focused image.
I have read every single posting on the topic and still have not found the answer.I have used every aperture/shutter speed/shooting mode possible, but still cant achieve anything but a slightly fuzzy image.
From minimum distance to about 1.5 m everything is razor-sharp, but beyond that it's all downhill!
Help please.
Regards to all
Dave

Dylan Couper March 25th, 2004 02:08 AM

Hi Dave
It would help if you could post a screen grab of the image for us to look at. The 3x lens is a little on the soft side.

John Threat April 27th, 2004 10:18 PM

One thing that will help focus if there is good light in the space you are shooting and you can shoot at a 5.6-4.8 F-stop for that sweet spot.

Stopping down with the ND filter to hit that sweet spot will really make a nice focused image possible.


Other than that.. I still maintain that Canon shafted us a bit with the 3x.

Ken Tanaka April 27th, 2004 10:45 PM

I agree with John's suggestion: light your scene up. Way up. Get that iris closed down to get deep focus field.

Also, you should note that video cameras' relatively low resolution (with respect to film) make for mushy-looking wide shots. This generally doesn't become apparent (at television-size images) until you look at relatively distant objects. If you're shooting interiors this may not be a factor in your current complaint. But it's worth keeping in mind prospectively.

Tight interior shots is the ideal application for that 3x lens. I've been very happy with mine in that application.

David Phillips April 27th, 2004 11:39 PM

3X Wide
 
Thanks for the replies, but now I'm even more confused.
John says open up the iris and Ken says close down for d.o.f. and go for tight shots.
If I needed tight interior shots then I'd use the standard 16X, the Idea behind the 3X was to produce wide interior shots for real-estate work. However, I do agree that the 3X is a bit of a leg-pull from Canon.
After being in 'stills' photography for over 30 years I find the transition to video not as straight forward as I imagined, but it does work if you stick to 'Video Rules' and shoot tight and close.
I shot one of my best ever weddings last week-end, simply because everything was c/up. I have no doubts that the XL1s and lenses are very good, used in the right conditions and sticking to manual operation will achieve unbeatable results.
My advice to anyone thinking of buying a 3X would be to fully understand its limitations and make sure it fits in perfectly with your requirements.
Regards, Dave

Ken Tanaka April 27th, 2004 11:54 PM

No, actually I -think- John and I may be making the same comment. That is, light the scene brightly to afford yourself (i.e. the camera) the opportunity to be flexible with your aperture. As you probably know from your still photo work, tighter apertures lead to deeper depths of focus. John remarks that you may find a "sweet spot" around f5.6, and that use of the lens' ND might be handy to achieve that aperture. Depending on colors and the depth of the scene I might even go down a stop or so tighter.

No, I'm not recommending tight shots, per se. Just remarking that video cameras, particularly small cameras like the XL1S, wouldn't be my first pick to shoot the Grand Canyon.

(Are we in fact coincident, John?)

Yi Fong Yu July 17th, 2004 06:50 PM

Can you take on all conditions of a 'indie' shoot with only the 3x wide lens?
 
I'm considering getting the XL2 body and just getting the 3x lens ONLY. Do you think this is wise? I'm only shooting features and shorts and will be using 24p ALL the time. Do I really need the 20x "L" series? I like the wide look and want to keep it for everything. I know that the 3x wide has less of a telephoto feature but I can't think of a reason for telephoto as I can't get audio so far away anyway (unless I dub it in while in post). So all in all I think 3x will be fine. Can anyone give me advice from their experience? I'm a novice!

Jean-Philippe Archibald July 17th, 2004 11:20 PM

A longer lens can be handy if you want shorter DOF. Perhaps you should consider to buy a good manual lens with a .6 or .7 wideangle adapter...

Dylan Couper July 17th, 2004 11:38 PM

I shot my last two short films entirely with the 3x lenses. So, sure. However, that was the tool for the job at the time.

The bottom line is the right tool for the right job.

Yi Fong Yu July 18th, 2004 12:12 PM

but i thought DOF should be achieved by moving further away from subject anyway?

Yi Fong Yu July 20th, 2004 06:27 PM

there any lenses that make telephoto out of the 3x lens?
 
meaning instead of taking a 16x lens and screwing century wide lens adapters to it, you take a 3x lens and screw telephoto lens to it. it this possible? converting a wide to telephoto?

Christopher Reynolds July 28th, 2004 07:35 AM

What kind of depth of field are you talking about exactly Yi? Shallow or deep? You can achieve a Shallow depth of field by zooming in and simply focusing on your subject, but keep in mind, this also increases the size of anything behind the subject, and in front of them for that matter. Also, opening the aperature up as far as you can with a good ND filter, gives more shallow depth of field. Closing up the iris can help with a greater depth of field as long as your luminence is high enough to keep the image from getting too dark.

Exactly... =)

Rob Lohman August 1st, 2004 11:54 AM

You have the Canon 1.6x XL extender for example that would
turn the 3x into a 4.8x lens, but that would not nearly get into
the same range as a 16x times. I don't think it is possible what
you want. I guess that's what the whole swappable lens feature
is for anyway. Just put the 16x lens on it.

Yi Fong Yu August 4th, 2004 01:46 PM

just got a 3x lens... gets blurry when converting from frame mode to 24p.
 
i just got 3x lens for me xl1s and it gets very blurry during pan shots when i convert from frame mode (30p right?) to 24p to burn on DVD. frame mode looks spectacular. there's no "need" to do that i was just experimenting. i mean ... how do people like soderberg use the xl1s and then transfer it to film and have it still look OK?

Jean-Philippe Archibald August 4th, 2004 02:05 PM

Ok, I have never do this thing and I could be wrong, but I don't think that it is due to the 3X lens. People like Soderberg generally use PAL version when they want to go to film. Because PAL is 25 fps and it is easy to convert to 24P. It is almost impossible to have good results with 30P to 24P. I have read somewhere that most of the transfer labs require to work with 60i instead of 30p (or frame mode) to convert NTSC footage to film.

Rob Lohman August 4th, 2004 02:09 PM

So you claim it goes wrong when you go from 30p to 24p. The
all important question is then: what software are you using and
which settings. The big boys have highly advanced software to
do such conversions as best as possible, usually with some
human supervision to tweak areas.

Yi Fong Yu August 4th, 2004 02:31 PM

vegas5.

John Mercer August 7th, 2004 05:03 AM

Why are you converting 30p to 24p? This will inevitably cause problems. It is not designed to work this way. To extrapolate 24p from 30p causes some serious artifacts.

If you shoot 30p then you are best to stick to 30p for all output. If you need 24p then you would be better off shooting on a camera capable of this frame rate.

Best regards,
John.

Jeff Donald August 7th, 2004 07:24 PM

It would be better to do 60i to 24p than 30p to 24p. Of course it is best to do 24p as John point out.

Michael Wisniewski August 7th, 2004 07:40 PM

Would it work any better if you converted 30p to 60i, then go to 24p?

Jeff Donald August 8th, 2004 06:40 AM

Probably not, but try a short segment and see what it looks like.

Yi Fong Yu August 8th, 2004 03:59 PM

good idea, i'll have to experiment next time i get my cam out =^).

John Mercer August 9th, 2004 03:47 AM

"Would it work any better if you converted 30p to 60i, then go to 24p?"

You can't convert 30p to 60i since it is already 60i, with complete frames over two fields as opposed to two seprate motion fields - it's still stored 60i on tape. You can't recreate motion where non exists.

The problem will always remain that 30p into 24p does not go elegantly. There will be serious motion artifacts.

I don't know what you feel will be gained by converting 30p into 24p - are you after more of a 'film look'? It will not add to this. Are you wanting to output to film? You'd be much better off shooting regular 60i for that with the Canon XL1s or get hold of the DVX100a for true 24p.

Best regards,
John.

Yi Fong Yu August 9th, 2004 07:23 AM

ok i plan to try the 60i->24p. i'm just experimenting with the film looks, yesh. i may also get the XL2 next spring, but meanwhile... need to emulate some 24p.

John Mercer August 9th, 2004 08:39 AM

"but meanwhile... need to emulate some 24p."

24p won't add anything specifically more filmic than 30p - it's only really useful for where you've shot in the format and plan to work in a 24p timeline for either transfer to film or 24p DVD - but if you haven't shot in 24p it is pretty redundant other than taking 60i interlaced footage for txfr to film.

24p derived from 60i has it's own set of problems too - though not as serious as 30p to 24p - you will get motion artifacts on moving scenes, caused by interpolation of interlaced footage to progressive.

Honestly your best bet is to stick with 30p (frame mode XL1s) and experiment with colour correction etc. 30p progressive can look just as much like 'film' on video as 24p and you will have none of the problems that you are facing now. There is nothing magical about 24p versus 30p that suddenly makes it 'film'.

Best regards,
John.

Yi Fong Yu August 9th, 2004 09:04 AM

ok thx =).

Nicholas Foster September 9th, 2004 12:24 PM

Question about 3x wide lens
 
Is the 3x wide lens for the Canon XL1s fisheye?

Jeff Donald September 9th, 2004 12:26 PM

No, it is not a fisheye lens.

Don Palomaki September 9th, 2004 04:17 PM

Field of view is roughly comparable to a 28 mm lens on a 35mm still camera.

Nicholas Foster September 9th, 2004 10:21 PM

Excellent. That's all I needed to know. Thanks for the help.

Bob Safay September 11th, 2004 04:16 AM

Nicholas, if you have the chance to get one go for it. You will be surprised how often you will use it. Bob Safay

Michael Dalton September 16th, 2004 12:42 PM

I second that!!
 
I love the lens! It does wonders for making you work not look like it is shot with a cheap DV camera, the added perspective makes the images more interesting.

Roger Moore September 22nd, 2004 08:41 PM

3X lens min focus: 3/4" or 0.5m...?
 
Canon site says it's 3/4" at wide end, while Adorama says it is 0.5m... which is it?

http://consumer.usa.canon.com/ir/controller?act=ModelFeaturesAct&fcategoryid=115&modelid=8274

http://www.adorama.com/US%20%20%20%20171962.html

Roger Moore September 22nd, 2004 08:42 PM

Because if it's 3/4" it may be possible to use this lens like a macro? Maybe to use this lens for a Agus35 or
Alain35?

Matt Irwin November 12th, 2004 04:10 PM

HELP! 3x lens stopped working... WTF?!!!
 
I'm in the middle of a shoot right now. We're shooting nights right now, and last night my 3x lens stopped working.

I've checked everything I can think of:

-Lens is seated correctly
-Lens control pins are clean.
-Iris set full open.
-ND off.
-Tested gain at all settings.
-Yes, the lens cap was off :)
-Shutter was where it should be.
-16x lens works FINE.
-There is no "check lens" warning flashing.

I can see all the HUD info in the viewfinder and on the monitor, but the image is BLACK. I'm on a 1st generation XL1. I've reasoned that the iris in the lens has locked closed or the control pins have 'shorted' somehow(?).

I really don't want to (and can barely afford to) send it in, although I may have no choice...

Anyone have any ideas?

Rob Lohman November 15th, 2004 07:28 AM

Are other lenses still working? If so then it is a good bet that your
3x lens is busted. If other lenses are not working the camera is
busted and the lens probably as well.

Now to check and give out a word of warning, NEVER EVER CHANGE
THE LENS ON THE XL1/XL1S/XL2 WITHOUT POWERING DOWN THE
CAMERA FIRST!!

Now you didn't do this, right? Otherwise you might have busted
the circuit in the lens for example. If the camera was powered
down then something else has broken somehow. If other lenses
still work you can reasonably assume it is the 3x lens and send
that to Canon. Otherwise both the lens and camera have to be
send it.

Matt Irwin November 15th, 2004 01:23 PM

Well....... That explains it. Heh. Heh.

Right. I dont think I powered down the body before switching lenses that night. Yes, it is only the 3x that has the problem.

Thanks for the info, Rob.
