This is a picture of my 10 year old Grandson Brennan, who came with me on location to Lower Basildon with his Hitachi 5.0Mp Camera because he wanted to take photos of trains "Like what Grandad does"... note the gelled hair :lol:

I'd say you are pretty Lucky Defiance...to have a grandson like that...and to have a grandson who apparently appriciates Cardi's, Trains, and Cameras...triple threat!!

See if you can encourage him to post his photos here, with us...
Wouldn't THAT be something..second generation CL, already...

Makes me smile to see that boy carry on the traditions...

The gelled hair makes me think this one walks to his own drum...
and that will serve him well..

Great shot, by the way, Defiance!!

This lens seem to produce very sharp pictures.
right?

The test results seem to show that it's one of the sharpest lenses of it's type from any manufacturer. It outperforms a number of primes.

Like Roy (aka Defiance) my example gets strapped in front of a 40D. Here are a couple of shots (clickable for the full-sized versions) that I took when the camera was very new:
    200mm, f/5.6, 1/320 sec.
    Developed: Auto contrast, Shadow/Highlight - Shadows + 25%
    Image
Not the finest landscape I've ever taken (honest :evil: ) but included to demonstrate how the longer focal lengths can compress distance. This shot was hand-held and while not pixel perfect I think without IS it would have been a lot worse.

    192mm, f/7.1, 1/640 sec.
    Cropped and Developed: Out of focus insect removed from the sky.
    Image
Wasn't even expecting this shot until the very last moment. Fortunately the lens was already fitted so I just swung the camera up and fired off a few shots. IS seemed to cope very well with the fairly rapid panning.

    200mm, f/5.6, 1/400 sec.
    Developed: Auto Levels
    Image
Hand-held again and like the last one taken from a boat so a tripod wasn't an option. Another tribute to IS perhaps, rather than my artistry! I think the sky would have benefited hugely if I had used a polariser.

Bob.

This looks like the perfect zoom. Relatively compact and light compared to its f/2.8 siblings, great IS, and phenomenally sharp. All the MTF charts and samples I've seen are amazing for a zoom. Even compared to some of the best primes like the 135 f/2 and 100 f/2.8 macro it holds its own very well. It seems like a no-brainer if you're looking for a zoom in that range.

Thanks for posting your write-ups and posting your examples.

Are there any zoom-creep with this lens?
You know, if tyou have it at... say 150mm and tilt it upwards or downwards the zoom is "creeping" ?

From my post over in the Technical and scientific photography forum:

The following shot of the Orion Nebula was made with a stack of three frames, each of 60 seconds duration at 200mm and f/4...

    Image
    Clickable (1.1 MB download)
The lens was, at a guess, only 30° above horizontal but there is no sign of lens creep.

And from my post in the same forum:

The following image is a 33% crop of Comet Holmes. An exposure of 180 seconds with my Canon 40D set to ISO 1250 and Daylight white balance and with my EF 70-200mm f/4L IS USM lens set to f/4 and 200mm...
    Image
    Clickable (545 KB download)
The lens was pretty much vertical during the exposure and there is absolutely no sign of creep.

Bob.

ok Bob, thanks.
I notice tho that on both these images the lens is at it max-end (200mm). A few lenses that have a "creep-problem" doesnt creep when parked at its ends.

Havnt heard that the 70-200 have a creep-problem tho, but i thought i should ask before buying.

Hi Khol,

I don't have any astro images taken at intermediate focal lengths but I have never seen creep with this lens.

Bob.

Stand to Attention and Salute.... Her Majesty's train approaching.

Friday saw the Royal Train going through Twyford Station probably ECS (empty coaching stock) as there where no Royal Flags flying on the front and probably heading for Wolverton... notice how clean the buffers are, no grease.

Over in "Still Life" Big Pix has an example of mono + colour, so I thought I would have a go but as it is not still life and it was shot with the 70-200 I have posted it here....

...... I like what you have achieved here, but have a look at a tad more contrast for the B&W so your image jumps...... and a nice pix as well....... but it leans a little to the left, so I put the D300 manual under the left side of the monitor for a quick fix........ at least I won't loose the manual :lol: :lol:
