Here's $0.02:
Ignore the crop factor. You pick your viewpoint to show product, or product in installed environment. You zoom to frame and crop in camera. A big deal is made of crop factor, but unless printing big, or doing a lot of wide angle, an APS-C sensor camera will do fine. Who gives a hoot.
How big will catalog ads or magazine spreads print? That really determines your body/sensor requirement. I did a trade show banner 7 feet long from a 6 MP shot. No one complained.
I'll tell you what toys I carry in my field location gym bag:
1. A decent tripod with a quick release head. Any tripod is better than no tripod. For your work, anything similar to: http://www.bhphotovideo.com …ghType=categoryNavigation
. Look for used.
2. A $20 double axis bubble level to avoid distortion of wide angle shots of products installed their landscape.
3. If you are in the SW USA, get a "warming polarizing filter" CP+81A, like a Hoya Moose Filter, to add inviting warmth and character to lighting product shots in the landscape. Buy the thread diameter for the largest lens you have, and use step down rings to fit other lenses in the bag.
4. Get a Whi-Bal card or similar for digital White Balance. I use larger 4x6. Any brand, but this is a must have product.
5. Get a $25 collapseable circular diffusion panel. For shooting reflective installed products in place, it is more important to kill specular highlight reflections and harsh daylight shadows than it is to add light with flash. There are lots of reasons I use these in field on stuff like irrigation equipment. You'll thank me. Any brand 22" or bigger is fine, like: http://www.bhphotovideo.com …EG&addedTroughType=search
. Diffusion reflector size depends on your installed product sizes. I can't over emphasize how much this is used. You can always do a longer low ISO exposure from a tripod in lower light, but you can't kill specular reflections without diffusion.
6. A sandbag to shoot from ground level, or counter weight tripod arm.
7. Small flashlight to manual focus aid in the dark before longer exposures.
8. A non-reflective seamstress ruler for sizing shots.
9. Pen knife, and especially small stainless steel scissors for gently and aesthetically cutting away plant parts from products without pissing off property managers.
10. Rubber knee pads for me.
11. Extra batteries and flash memory cards in waterproof cases.
12. A shutter release cable.
13. Spritz bottle with water to add fact dew drops when appropriate.
Ok, that's my junk bag. I also use a QFlash, but let's not go there.
As far as camera, any used 20D, or a 30D, or a Nikon, they'll all do fine. The Canon XT series does not have Canon's quick control dial, nor the LCD on top, and are less convenient when on location, on tripod, for ground level shooting, which you will do from a tripod with lighting in a landscape. A deal breaker for me using XT line, but the Canon XTi is a cheap fabulous camera.
Lenses?
1. A CLOSE FOCUSING wide angle zoom to get close to product, and then let perspective have other parts of shot diminishing in size is kind of essential. A Canon 17-40L, an EF-S 17-55 IS, Tamron 17-50. That kind of thing. It's impossible to make a specific recommendation. Many lenses will do the job. The Sigma 17-70 focuses very close for this work, but I know nothing of its quality. I use a 16-35 for this stuff.
2. A tripod mounted telephoto. Here, you stand back at sunset, lights are on, and shoot the pretty family sipping wine on their patio, with curved walkway and patio lighting, and COMPRESS everything in the distance, highlighting the job your company just did. For a corporate landscape, you'd do the same shot with the wide angle on tripod and bubble level.
It's a bizarre recommendation, but I'd tell you to buy a Sigma 150mm f/2.8 macro, which will double use for isolating close-up shots in the landscape. If not, buy a 200mm tele, or a 70-200 lens, and buy a 60mm or 100mm macro lens separate in the future.
I know opinions are cheap. With this in mind:

I have a hot shoe flash and tripod so I am good there. "Crop factor"...yes I've heard referance to this and need to read more. I really don't want to drop more than about 800.00 on a body and maybe 500.00 a lens for now. I think that I can pull this of for that kind of coin right now anyway.
I just do a 20D, and the Sigma 17-70 to start, with some accessories... Jack
