But Nikon lenses cost 2-3 times of similar spec Tamron/Sigma lenses! Sigma offers 3-yr and Tamron offers 5-yr warranty (much higher than Nikon's 1 or occassional 2-yr warranty).

Most people who upgrade from P&S cameras will prefer auto focus anyway.

Yes Nikon lenses are best but more expensive. So it is always a trade off.

They're honestly not. Typically they're about 30-50% more expensive, and worth every penny.

There's really no point buying a DSLR in the first place if you're going to put a cheap lens on it - you could get the same result (often better!) for a fraction of the price with a point-and-shoot compact camera. What's more, the compact will be far smaller and lighter too!

In Amazon,

Nikon 18-200 VR = £550+
Sigma 18-200 DC Macro II = £255

Nikon 17-55 F2.8 = £1257
Tamrom 17-50 F2.8 VC = £326

DSLR's sensor is far larger than P&S's sensors! That alone is good reason to buy DSLR over P&S.

It's also worth bearing in mind that the original brand lenses (Nikon, Canon etc.) retain a lot more value than the third party brands, so you might want to take resale value into account as well as comparing up front prices.

I wouldn't select based on resale value. Technology is moving ahead all the time. In few years time, there will be lot more features in newer lenses which may render old lenses [whatever brand] less attractive.

For example, people now prefer auto focus + VR/IS/VC/OS in lenses. So old lenses are losing values fast. Moreover you might accidentally break your lens. So resale value is never guaranteed.

Fair point. They are seriously cheap.

I have to disagree here though. Firstly, the sensors on the better quality compacts are much bigger than they used to be and in some cases are the same size as a DSLR. Secondly, unless you're going to fork out for decent glass, you simply won't see the benefit of that big sensor. All you'll get are the downsides of much bigger, heavier, and more expensive kit.

I'm afraid this is nonsense. Professional kit holds its value very well and always has, because technology doesn't move quickly at all in lenses. Pro lenses that Nikon produced 30 years ago are still capable of taking outstanding pictures and they're still not that cheap!

In many cases, the latest generation lenses use exactly the same optics as the old ones - the only difference is slightly faster focusing and, sometimes, image stabilisers, which aren't as useful as you might think (and are certainly no substitute for a fast lens and a sensitive chip).

Kimwoo is correct - high quality Nikon or Canon lenses hold their value well, as a quick trawl though eBay will demonstrate. Sigma and Tamron lenses rarely do.
