New Camera & Lenses buying help

I am looking to upgrade from Canon digital S2 IS pro point & shoot camera to a digital SLR camera
I'm looking at the Canon Rebel XTi/400D & Sigma Lenses the Sigma 18-50mm f/2.8 EX DC macro & Sigma 50-150mm f/2.8 EX DC HSM & Sigma 100-300mm f/4 EX DG HSM & Sigma 1.4x APO EX DG teleconverter, I'm open to all opinions, what I do is go to antique tractor shows & antique car shows & take photos of the tractors & cars & travel around taking photos of barns & farms & then sell all the photos at the antique flea markets

Thank You all

If you will be working at close range for the tractor pictures, will you need an ultra-wide lens such as the 10-20mm?

I know the lenses you list give you a continuous range, but would the 18-50mm and 100-300mm be sufficient on their own? With having the converter do you need to fill the 50-100mm gap?

Just questions I know, not answeers, but I hope you find the thoughts useful.

Hi johnriley
No realy close up work as try to get owner to set tractor out in the open so nothing in back ground, the teleconverter will not work on the 18-50mm, so thing most of my work will be done in the 18-150mm range I know sigma makes a 18-200mm but from the reviews I read it best to go with a 3x or less zoom Lens & I'm looking to get very good to extremely good image quaility & resolution to print 8 x 10, 11 x 14 & 13 x 19 inch photos & I am living on low income so I will have to save up 2 months & buy Camera then save up 2 more months & buy a Lens so what Lens should I start with

Thanks

It's possible to get a terrific A3 print from a 6MP camera, so I'd be inclined to look for a package of either the Samsung GX-1L with 18-55mm and 50-200mm Samsung lenses or the Pentax *istDL with the same lenses branded Pentax. All these items are made by Pentax and offer terrific value at around £399 for camera with the two lenses. How can you go wrong at this sort of price with this sort of quality. Would that suit your budget?

As far as Canon is concerned I hear that the kit lens is not good, so it may be better to think more widely. If you go for Sigma, depending on costs, perhaps the 18-50mm could be the most versatile lens to start with, followed by the 50-150mm?
