I've had mine for several years and have never been disappointed with it. I shot the America Cup races with it on a monopod using the 1.4 and 2.0 TC together for 1120 mm total. Shooting the Cats at 50 MPH it did great. You can see the images at FM Forums under sports.

SJPRG,
Could you include a link to your pics on FM Forum. I'd love to see them but there are so many in the sport corner I gave up searching :(
Thanks,

The following link has been shared before. But as far as I'm concerned, the article is one of the best real world comparisons of a 5DII vs 7D IQ when reach limited. It's worth the read...

Maybe in the future, but I really need a macro right now.

I have to ask the obvious question, your title says "What Canon lens for fashion/portraits???" so why to you need a macro for fashion/portraits?

Do any of you guys ever print your photo for framing? An "8x10" mat covers .25in. on each edge of an 8x10 print. I've found it really helps to have some extra space around your subject to account for that and/or cropping it for different aspect ratios prints ( i.e. 4x6 or 5x7 or 8x10 or ...?).

There is no way to "frame it perfectly in the camera" and account for all these cases.

The portrait as envisioned by the pigeon when he commissioned the work...




The portrait as delivered by the hipster street photographer claiming to be a portrait artist.  :)

Just a little humor.

Technical Support / Re: Help needes: EOS 7D - noisy pictures
« on: July 03, 2013, 03:44:13 PM »
Dani,
You said "This frame shows the full picture". I have a 7D and I've never seen noise like this using ISO 200 except for extreme crops or if you push the exposure a lot in post proccesing. Taking a close look at the noise it looks more like JPEG artifacts. I can even see what looks like the 8x8 macroblock structure.

If this truly is the full image that was captured I would ask the following.
1. What recording format were you using? Large, Medium, Small, RAW, M-RAW, S-RAW?
2. How was this rendered to the JPEG image shown? In the camera, in post processing. With what tool and setting.

Cheers,
Doug

Does anyone have some good real world example photos of before and after using FoCal that illustrate the improvement?

Thanks,

Here is an example of a "real world" test case where it's pretty easy to tell, without pixel peeping, whether or not you have a issue with front or back focusing.
-djd



Canon EOS 7D
Focal Length    400mm
Exposure    1/160
F Number    f/5.6
ISO    3200

Is it?  Its just one image.  Things are not quite so simple.
 
Please consider the following:
 
 
The Canon AF system varies from shot to shot, so a thorough test requires that you take several shots setting the lens to infinity or mfd before each shot.  Then you need to throw out obvious misfires, and average the others.
 
That one image that appears to be perfect could, in fact be a misfire, and the other nine be OOF.
 
2. With a wide aperture lens, the depth of field is very shallow, so its difficult to spot the exact focus on a three dimensional object.
 
3.  You do not "KNOW" exactly where the camera tried to focus, it could have been on the beak, the foot, the tail, or the board the bird is standing on.  A properly designed target will insure that the AF system will try to focus on the same spot every time.

Mt Spokane,
You are absolutely correct. I never intended to imply one photo was enough. It was just to give a real world example for which you should take several to determine if you have a problem or not.

I agree with all the other points you bring up as well which also emphasizes the fact that there are lots of other real world reasons why we don't always get perfect focus where we expect in an image. And they have nothing to do with AFMA.

Cheers,
DJD
