This lens is a monster and its Images stabelizing is pretty damn good

In this video i show you a review of the canon 100-400mm l series lens with IS. and USM.

its fast focusing and is a massive telephoto lens and when worked along with the canon 550d and have it on the crop movie function where it uses the central 640/480 pixels then you have it at a 7 times zoom. and 7 times 400mm on a cropped sensor makes it about a 1000000000mm lens a bit like a telescope!
you can make the zoom smooth or tight so that you dont have barrel creep when not using it.

not so great for portraits but shooting a snowboarder falling down a mountain across the valley it would be A MA ZUN!

enjoy

Because you pushing an pulling does this increase the chance of getting dust in the lens?

[Dombowerphoto]

@JifferRiffic i would suspect so. but not just the lense but also the sensor if you are doing video or have live view enabled

[jkddaddy]

Dom,

how are you autofocusing while shooting video? I know it's possible but I thought it was slow and prone to hunt. In your video it looked fairly fast and precise. (and no break in the video for "quick focus"). Thanks!

[Dombowerphoto]

@jkddaddy just using the autofocus on the canon 550d, I think it is the same focus as the canon 60d and 7d. if it is good lighting it doesnt hunt that much, and also this is a very good lens

[sasktank]

does the canon 7D have the movie crop function ???

[Dombowerphoto]

@sasktank I dont think so unless they added it to a firmware update but otherwise no it did not, the canon 550d was the first to have that function

[midoel71]

Wao nice....Good knowledge, canon are great cameras. I am currently saving for a canon 60d. I would encourage great photographers like you to visit children hospitals and orphanages and take some good pictures of these kids. They would love to be a model for a day. I will difinitively do this once I get mine. Take care

Neat, it's püsch and püll!

I can't help it but..

"Huuuuugggeee monster"... That's what she said.

[neyzenilkay]

Lens fapping :D

[omgtkseth]

true that about the auto focus. I must say that I have used sony dslrs and they were better at autofocus, it focused like its seen here, which is rare with my 550D...

[csruinedmylyf]

omg ! dats a huge zooooooooooooom!

attach a sniper rifle wid dis lens ... and u r good to go!

[Szeba86]

@captainjman1976 hmm I forgot to mention that slow lenses are also good but only in controlled environment where you have total control on lighting e.a studio, it all depends on the purpose but even here a fast lens will outperform a slow one.. it will be much sharper stopped down :D

[captainjman1976]

@Szeba86 Agreed - as good as the kit lens with the 5d mark II was, it was an F4. I decided to return the camera and buy just the body and get all 2.8L glass. I find myself getting shots I would never have the chance to get with slower glass. Its worth the extra money. Zihab is right, the body is not something you are going to keep long term. But the lenses you buy should be a lifetime purchase. Now that canon also makes a "red one" type of video camera with EF mounts...need I say more?

[insanelypositive]

@6:28 the guy coming down the hill has got a Canon L series lens.. i suppose :D

[jailbird111]

@Zihab2000 first try to get to full frame body (no megapixel race here) then go for lenses. i am having nikon d300s with some good lenses but now after i have bought canon 5d with 50mm 1.8 nifty fifty i occasionally use d300s.
