Canon 100-400mm L 4.5-5.6 IS

Just picked up this lens and first impressions very happy, the slide zoom people hate or love is easier then I thought and quick.

Had to take a few images in the backyard.

Its always exciting playing around with new gear.

Dont ask me what bird this is but it is young thats all I can tell you.

Shot at 400mm hand held up on a ladder.
I was approx 8-10 meters away from the bird.

Iso 100
Aperture F9.1
Exposure 1/100
Manual settings

Wow Tony, you're amassing quite a range of top notch glass there. I would have liked to go for the 100-400 L but it was out of my price range so opted for the consumer grade 70-300mm IS instead. Look forward to seeing more of what this lens is capable of.

And the bird, it's a grey dappled yellow beak oople dook

I only have two types of birds... duck and birds

cheers

Robert believe me the glass is a lot more capable then me the user, the reason is if I didn't have nice glass I would blame the glass if the image was ordinery, this way I only have myself to blame and it seems to be happening a lot...hehehe

Nice pic.. May I ask though, why did you stop it right down to F/9.1? the lens is very capable at wide open aperture and in fact usually better wide open..

One problem with the slide-zoom lenses is that they act rather like a vacuum cleaner. When you zoom out to the longer focal lengths, they suck in all sorts of stuff, which ends up on the sensor. Probably OK with the 40D which has sensor cleaning, but some people swear AT them, not BY them.

hi Mike,

Yep read all the reviews about a thousand of them, some have said they had a problem and some have never had a problem and the ones that did have the problem worked in dusty conditions that really isn't recommend for any type of imaging if you want to look after your lens's.

It was a choice between the sigma 50-500 or the canon 100-400 and seeing my mate has the Sigma 50-500 which I didn't like the choice was easy.

But like you said care needs to be taken and common sense.

Yeah, I had a sliding nikkor 80-200 F/2.8 that sucked in dirt... I stick to primes as much as possible these days... less moving parts....

If I had the choice of the 50-500 sigma or the 100-400L, I'd say there was no choice... just one option, the 100-400.... I've had sigma lenses, and whilst my 170-500 sigma was a really really nice, sharp lens, it just wasn't L glass... focusing was painfully slow compared to the 400 prime, or the lightning 70-200F/4

Yep I agree, there's mixed reviews and I've heard of the dust problem, others say it's not an issue at all.

I must admit it's probably my least fav L lens but having said that I've never used one so can't comment.
I am impressed with the IQ you've achieved with it so far though Tony so good pickup.

the old siggy 170-500 wasnt HSM. the 50-500 and 150-500 are pretty quick at focusing apparently. the many reviews i have seen say so anyhow.

if it was a quality issuse i'd have gone the 50-500 cause its an EX and the build quality is quite good as are the coatings.

Nice lens, nice shot. The one thing I don't like about this lens is the zoom lock also locks the focus. I sometimes find that annoying, I'd like to be able to lock the zoom but not the focus. Other than that, very very sharp, nice lens. Heavy!
