Martin,
Unfortunately, my web site is in urgent need of an update, and not all images on it were taken with the D30, or any of my new lenses... BUT:
Currently my lens line-up is:
EF 20mm f/2.8 USM
EF 28mm f/2.8
EF 28-70mm f/2.8 L USM
EF 50mm f/1.4 USM
EF 70-200mm f/2.8 L USM
EF 100mm f/2.8 Macro
EF 300mm f/4 L USM
EF 1.4x Extender II
...plus I've got some other odds and ends, such as the Kenko extension tube set, etc. I am currently thinking about buying the EF 16-35mm f/2.8 L USM, since I have made a commitment to the 1.6x "conversion", or crop factor, of the 10D for at least another couple of years. It also does not hurt that 16mm on full-frame (or film) will be a really wild perspective (and yes, I mean "wild", not wide"!
). I am holding off for a few weeks, just to see what the new EF 17-40mm f/4 L USM lens will be like. I'm leaning towards the 16-35, but who knows?
It has taken me some time to build up my outfit to what works for me, and what I like as far as image quality goes, etc., and since you're new to DSLR, I wouldn't expect you to buy into L lenses straight away, so here are some of my recommendations for a cheap lens line-up:
EF 24-85mm f/3.5-4.5 USM - this is a great lens for the D30/D60/10D! I would recommend it well before the EF 28-135mm IS USM that many people (including me) seem to get. The 28-135 IS is a great lens, but build quality is not that great, and the 24-85 is better optically.
EF 75-300mm f/3.5-5.6 USM - as much cr@p as this lens cops on the Internet, you'd think it would be no good, but personally, while clearly a consumer zoom, I have found no great problems with this lens. The photo "Who's the Pretty Boy", on my web site, was taken with the D30 and this lens, before I bought my first L lens. The lens is not perfect, but it is cheap, and better than no lens at all!
I wouldn't recommend the IS version, as I think you pay too much for consumer quality IS, and the value for the buck that you get with the non-IS version disappears. If you're inclined to spend more money, and want the 300mm reach, I'd recommend the EF 1.4x Extender II with the following:
EF 70-200mm f/4 L USM - this is a lens I would recommend over the 75-300 USM, if you can make the effort and save a little longer. It is one of the sharpest zooms Canon make, and surprisingly cheap for the quality you get with this lens (build quality as well as image quality). I traded mine for the EF 70-200 f/2.8 L USM and, with the exception of f/2.8, the f/4 zoom can do anything the bigger zoom can do! In addition, it is smaller and lighter, so you're more likely to carry it around with you.
For the wide end I would choose from these three:
Tokina 19-35mm f/3.5-4.5 - surprisingly good for the price. Better than some much more expensive Sigma wide-angle zooms!
EF 20-35mm f/3.5-4.5 USM - very nice zoom from Canon, not too expensive
EF 20mm f/2.8 USM - REALLY nice prime from Canon, and one that is currently in my line-up. I found that I was using my Tokina 19-35mm mostly at the widest setting, so I traded it in for this prime. It produces better quality images than the zoom (as it should), and is a pleasure to use.
