EF Adapter with XL H1

Yes, the XL H1 gives this warning with the EF adaptor. However, not sure whether it takes as long as 10 seconds.

Many thanks for the information Lauri. Does the warning message prevent you from recording? If it does then I can see that waiting even 5 seconds for the warning message to disappear is a major disadvantage. I think there would be quite a few occasions when it would make all the difference between getting a useable shot and missing an opportunity.

Any clarification on how long it lasts and whether it stops you recording would be very helpful.

Thanks again.

In my understanding no, at least I have not noticed that it blocked from recording. I'll check this and measure the precise time next time I attach the adapter to the camcorder.

[Paul Doherty]

OK thanks for that. It's good to hear that it doesn't stop you from recording. If you get chance to check exactly what it does that be very useful to know.

Once again thanks for your help.

Best Wishes for 2006

Hello friends,

I tried to record without lens at all (to capture a picture through a microscope via an empty toilet paper roll).

XL H1 announced "NO LENS" in red but it was recording fine. My guess is these are only warning messages. Thanks Canon to not lock the camera up.

I wish you all a HAPPY NEW YEAR from our snowy landscape with about 25 cm of new fresh snow.

the toilet paper roll lens! brilliant! i love it! that's the best use of an H1 yet!

yet another question for lauri: have you, by any chance, tried your 100-400mm telephoto lens yet? since it is telephoto, it is probably not as sharp as the prime, but is it sharper than the 70-200mm on the H1? i have been thinking about purchasing one of these for a still camera, it would be nice to know if it would be useful on the H1 as well....

This lens produced less sharp image with XL2, so have not even thought about it.

Hello Lauri,
I would be very interested by more details on this lens and the XL-H1. Even if there is a loss of details, do you think this solution is efficient for wild life videomakers ?

If you, or someone else, can post a picture made with the standard 20X zoom at max (average 700mm in 24x36) and the 100-400 at 100 (average 700mm too in 24x36), that would be very instructive.
I suppose that above 200mmm on the 100-400, it becomes too much difficult to target the subject...

Thank you !

As you wish; I'll try tomorrow to take the shots you ask for.

[Ronan Fournier]

That's very kind, Lauri. Thanks a lot!

[Lauri Kettunen]

Ronan, there's now a comparison betweeen the standard 20x and the EF100-400L lens at my webpage www.luontovideo.net -> Special.

The footages were taken indoors, for I've been working outdoors the few hours when there's some light. The settings were gamma=cine1, gain=+12db and some fine adjustment with the custom presets.

[Robert Mann Z.]

so whats the verdict, the only thing i can tell from the mpg is that the eos is darker...

do you have uncompressed stills to show resolution?

what are your eyes telling you?

is the eos adapter killing resolution on the h1 like canon says?

alot of questions ...thanks

Yes, because there was not enough light for the EF100-400. Verdict? If we are only able to tell that the eos is darker, that already suggests the EF adapter and the EF100-400 (in the 100mm end) is not bad at all.

I'm at the artic circle right now and don't have any monitor to view the footages in full rez. Consequently, bit hesitate to make definite conclusions. However, I did look at the footages in Premiere, and was bit amazed that the footages were so close to each other. (Still, in the 400mm end the EF lens is not as good as the 400mm prime.)

Summing up, so far I see no reasons why the EF adapter and lenses could not be used with the XL H1. The whole thing seems to work just fine.

[Ronan Fournier]

Thanks again Lauri !

Very interesting. It's true both images are closes. However, even if the EF is darker, it seems that the contrast is a bit higher and I can't see chromatic aberration in the corners of the picture, on the contrary to the 20x's picture (magenta, in the left edge of the box, ).

So, for the moment, it appears that we may think about this EF 100-400 as a 720-2880mm lens (because of the x7,2 coef) for wildilfe filmaking.

Now there is another question : at the 200mm range, I suppose the 70-200 is better because, among others, it opens at 2,8. So the 100-400 is usefull only if it is possible to shoot in the range between 250-400mm, (which means 1800-2880 !)
In your opinion, what is the higher useable focal limit, when pan and tilt (with a good tripod of course). Do you think the 350-400mm range in useable at last for fixes shots ?

By the way, is it the same EF adapter than the one for the XL1 & XL2 or a new designed for HD ?
