EF-S lenses:
can only be used on APS-C cameras and not on APS-H or full frame cameras
still no 100mm image stabilised macro lens with wide aperture for portraiture as well as macro work.
current EF lenses are not optimised in either focal range or optical quality for digital SLRs, let alone the APS-C cameras
most of the L series telephotos are white which may be good if you are an extrovert pro at sports events, but not so good if you don't want to scare everyone around you and draw attention to yourself. Furthermore, you may not be allowed into sports events with one of these unless you have a pro photographer's permit pass for the event.
EF tele-extenders are only compatible with certain lenses
mainly the white L zooms and the telephotos of 135mm or more excluding the 135mm soft focus lens.
you can use it on the TSE 90mm and 45mm lens as well as the MP E65 f/2.8 1-5x macro lens.
they reduce the lens drive speed for AF - 1.4x reduces it by 50-67% while 2x reduces it by 75%.
using a tele-extender results in an effective reduced aperture (1 stop for 1.4x and 2 stops for 2x), in addition to allowing less light in, this may decrease the efficiency of the AF system, particularly if the resultant maximum aperture is less than f/5.6. The Canon body will report the effective aperture of the Canon combination BUT not if you stack two tele-converters.
The 1.4x tele-extender has a significantly protrusive front element which will hit against the rear element of most other lenses.
see http://photography-on-the.net/forum/showthread.php?t=41922 for compatibility tables.
If you mount a Sigma Tele Converter 1.4X EX or 2x EX to a lens that is not listed in the compatibility tables it may damage the teleconverter as well as the lens.
if you plan to use an EF tele-extender with a non-EOS lens such as a telescope or MF lens as you get a "connection error" message and the camera will refuse to take the photo, but fortunately there are 2 possible hacks to get around this:
put tape over the autofocus contacts between the camera and the teleconverter
if using a T adapter to the telescope, use a special T-ring that includes "fake" electrical contacts
auto-focus:
For hand-held non-action photography, you are best to just use the centre AF point as the 49 AF points in the 1DMark III tend to mostly select objects other than your subject if there are other objects in the central field of view which are closer, and more contrasty than your subject which can be really frustrating.
the 10fps mode of the Canon 1DIII is only available at shutter speeds 1/500th sec or faster.
the faster x-sync mode of 1/300th sec is only available on Canon EX speedlights while studio lights may need 1/60th sec.
custom WB on Canon 1D Mark III is quite cumbersome to set.
using non-EOS lenses on Canon dSLRs:
you can buy adapters to fit legacy manual focus lenses to be used in stop down mode BUT:
for AF confirm to work (centre AF point only), you need an adapter with AF-confirm EOS circuit connectors on it
the OM version I bought from China on Ebay had the circuit connector fall off within 2 days of mild use so had to glue it back on.

Nikon G adapter also allows aperture control of Nikon G lenses which don't have aperture rings.
Canon FD lenses require a special adapter with optical elements which will impact image quality so FD lenses are not an ideal option.
manual focus will be very difficult to achieve accurately unless either:
use a split-prism focus screen
camera has a live preview with 10x live magnification (eg. Canon 1D Mark III)

Canon EF 85mm f/1.2L II USM - compatible with e-TTL II flash;
AF twice as fast as the older Mark I version but not as fast as the f/1.8 version (no longer made)
"This lens weighs 2.4 times more, costs 6.2 times more and focuses only about 1/2 as fast as the EF 85mm f/1.8 lens. The greater weight and significantly slower autofocus function than the f/1.8 lens may make it a challenging tool for some action/performance photography applications such as basketball (but may be OK for gymnastics)"
a great portrait and wedding lens, not so good for moving toddlers, animals.
much better for astrophotography than the 50mm f/1.2 (flatter fields and sharper edge to edge)
Canon EF-S 17-55mm f/2.8 IS USM
2007:
Canon APS-C lens outfit:
Canon EF-S 17-55mm f/2.8 IS USM:
645g; 77mm filter; 27-88mm; closest focus 0.35m
Canon EF-S 17-85mm f/4-5.6 IS USM:
645g; 67mm filter; 27-136mm; closest focus 0.35m; a bit slow and only medium quality;
Canon EF-S 18-55mm f/3.5-5.6 IS:
introduced 2007
equiv. to 16-35mm, this has reasonable build quality and minimal aberrations with good resolution. Not dust proof. 385g; 77mm filter; 63-107deg;
for the 1.6x crop, it is more useful wide angle than EF 17-55, EF-S 17-85, EF 17-40 but could be sharper and more weatherproof.
said to be better than the Nikon 12-24mm, the Tamron 11-18mm, and the Sigma 10-20mm
less distortion at 10mm than a Canon 16-35mm L on a full frame.
Canon APS-H lens outfit:
31-137mm;
introduced in 2005
more distortion, vignetting than the 24-70mm but more contrast, and lighter & with the IS makes it a better general purpose lens to carry around
seems a bit soft to me
0.23x macro;
$A2000
http://www.luminous-landscape.com/reviews/lenses/28-105.shtml
RRP $A2700 great lens but no IS and its heavy. Its wide aperture makes it better for sports.
Canon EF 16-35mm f/2.8L II USM:
21-46mm on 1.3x crop; 82mm filter allows polas without vignetting; weatherproofed; av. street price $US1600;
better image quality than the EF 17-40mm f/4L, but at 24-35mm, neither of these comes close to a EF 24-70mm f/2.8L
