When I bought the FZ30 back in June, I was about to purchase a DSLR (I'd actually transfered money from one account to another) then I saw the photos on WAB using the FZ30 and had a drastic rethink. Why buy a DSLR - well you do that to swap lens, but the FZ goes from 35mm to 420mm, and it does macro with the Raynox attachment.
For 25 years I've carted about a bag full of lens and other equipment for my SLR. One shoulder is now several inches lower than the other as a result and I swear I walk lopesided as a result. But mainly the stuff in the bag stayed in the bag, and laterly the bag was left in the boot of the car. When the equipment was carted about, by the time you'd switched lens the moment had passed anyway. So basically all that equipment, at least for me, was hardly ever used, I just stuck with the 70-210mm tameron zoom and a doubler.
So I checked what others were getting in macros, birds, landscapes, and portraits with the FZ and decided to get that instead. Now undoubtedly a prime lens is going to be far better than a zoom, but then you need a 28mm, 50mm, 105mm or 135mm macro, 200mm, 300mm or 400mm lens. Which is a lot of optics and a lot of weight. to cart about. So unless you've got a spare golf cart, you end up sticking a general purpose zoom on the front of it which sort of defeats the purpose of a SLR.
Just my opinion
