If you've got the cash, splash out on a Nikon D700
Agreed, and whilst you're at it you might as well buy a space shuttle for that commute to work.
The D700 is a pro camera. It's not entry level, it's not mid-range, it's not pro-sumer, it's a pro camera. It's an epic pro camera, and there's nothing stopping you using it if you're a newcomer, but the main advantage to the D700 is how good it is in low light, of which Mr. Fuhrer has indicated no need for, so it would be a monumental waste of £2500+.
A budget would be nice - ideally a budget of how much you want to spend and how much you're willing to spend.
I'm going to talk from a Nikon point of view, as that's what I know. Canon are around the same level and Sony are making strides into being a 3rd viable alternative, but their choice of lenses are still a little limited and/or expensive in comparison to Nikon and Canon.
A D3000 is good enough for many, but if you feel you're going to get into taking shots and feel you'll want something more in the future, you might as well go for a D90 straight away, as you
will eventually buy either that or the D300S.
The D3000. It's essentially a D40x/D60 with a new name, so if you can find a D40x for cheap 2nd hand, you might as well consider that. The disadvantage to the D3000 (and D40, D40x, D60 and D5000) is that there is no motor for the autofocus in the camera, which means the lens has to have the autofocus motor in it. That's not very limiting, as most lenses do have the motor now (for example AFS lenses for Nikon and HSM for Sigma lenses both have focus motors) - however it does rule out the fantastic value 50mm f1.8 "Nifty Fifty" unless you're willing to manually focus (Canon also do a Nifty Fifty by the way). The D5000 does have a swivel LCD screen, which may be of use (for me it's just another thing to fail/snap off and I wouldn't use it anyway).
The D90 is excellent in low light (not up there with the D700, but similar to the D300), has the built in motor, more focus points, is quicker, is better built and is bigger than the entry level cameras above. It's not big by any means, more that the above are quite small, and you're more likely to find the D90 better to hold. There is also the D80, which can be had quite cheap 2nd hand (see bottom paragraph). It's not particularly good in low light (but is better than the D40-D5000) and doesn't have video, but it does feature most of the other features of the D90 - bigger, better build, more buttons so you don't have to dive into the menu, is quicker and has the built in motor.
Lenses look to be fairly easy for your uses. Many newcomers want to shoot random shots, portrait and motorsport or wildlife, all of which ideally would use 3 different lenses - a short zoom lens (17-50mm) for your everyday walkabout lens, a midrange prime lens (50mm or 80mm) for portraits and indoor use without flash and a long zoom or prime (70-200mm or even a 300mm prime) for shooting cars or dicky birds.
Your use would be landscape (so maybe a 10-20mm), sport (could be a bit trickier depending on the sport) and random (17-50mm). You should be able to get away with a 17-50mm for the landscape easily enough though.
Either way, I'd sway away from the kit-lenses you get with any camera and get a body only and choose your lenses separately. The kit lenses are OK, and decent value, but most get rid of them pretty quickly.
My choices for a walk-about/landscape lens would be between the Sigma 17-70mm f2.8-4.0 and the Tamron 17-50mm f2.8.
The Tamron is pin sharp, fantastic value and very popular. It also features a maximum aperture of f2.8, which is good for 2 things. It allows you to shoot in lower light than if you had a smaller aperture (a higher number) and allows you to blur backgrounds more than if you had a smaller aperture, making the subject stand out more. It all sounds quite complicated, but you'll pick that up quickly. It's not a quiet lens though - when it zooms it is audible, but not massively loud. The slightly older Tamron 17-50 (the non-VC (vibration compensation)) is better than the newer one with VC - the VC is in the product name of the new lens.
The Sigma has the same aperture at 17mm, but it scales up to f4.0 at 70mm (and it scales between f2.8 and f4.0 as you zoom more), which isn't as good as the Tamron, but you do get a little more length to zoom with. It's not as sharp as the Tamron either. You have to decide between zoom flexibility (Sigma) and getting the optically better lens (Tamron). I've got the Sigma, it's a good value lens, and I appreciate the extra zoom, but I have to admit I regret not getting the slightly more expensive Tamron, which I've used a couple of times.
Both of those lenses I'd also get if I had a Canon body.
The choice of longer lenses if you need more length for sport will be determined more by what you're going to be shooting, but a popular budget choice is the Sigma 70-300mm f4-5.6 APO (make sure it's the APO and not the cheaper non-APO, which is a bit crap). Again, it's quite loud at zooming, and doesn't have a small aperture, but it's a decent lens and better than the Nikon budget 50-200mm. The Nikon 70-300mm f4.5-5.6 is a sharp lens and well built, but quite expensive. Personally I use a Sigma 150mm f2.8 prime lens - it's not especially long (but then I tend to take my motorsport photos at Knockhill, where you're almost on top of the cars) and it's also a true macros lens. It also happens to be one of the best lenses out there, but then it is expensive. The Sigma 70-300mm isn't a true macro lens - it will allow you to focus close to a subject, but you'll only get 1:2 magnification, so if you take a macro shot at 300mm the output will actually be more like 150mm.
If you've got a mate who has Nikon or Canon with a selection of lenses, I'd consider going for the same brand, as you may be able to steal his lenses every now and then rather than hiring or buying your own.
Either way, what I'd personally do is head down to a Jessops or other camera shop and handle both Nikon and Canon and see which feels more comfortable in your hand - just don't buy from them straight away as they're probably not the cheapest. Keep in mind that once you've got your first camera, you either have to stick to that brand or sell it all and switch, as you can't interchange lenses between different brands (for example a Nikon-fit Sigma lens won't fit on a Canon camera, even though Sigma makes lenses with both Nikon and Canon mounts).
When you do get a camera, I'd personally buy either one of the 17-50mm or 17-70mm lenses I mentioned above and stick with that originally, as it might be all you need. If you find you need more length, then you can get a 2nd lens. If you're not sure which other lenses you need buy the 17-50 or 17-70 and then hire a couple of other lenses. I can personally vouch for
Lenses for Hire and they don't charge a deposit - only the hire cost. It's also useful if you're going to an event and only need a lens for that week, so it might not be worth buying a lens outright.
One more thing. 2nd hand is normally fine for camera gear. People think cameras and lenses are so delicate that they treat them with silly amounts of care and the majority of the time with 2nd hand the worst you'll find is a few scuffs on the shell of the lens, while the internals and lens themselves are in perfect shape. If you can make a decent saving and trust the seller, it's worth going 2nd hand.
