I want to buy digital camera?

But I'm confused among samsung pl210, sony wx7, nikon s3100,fujifilm 900exr.I want that in which I can use optical zoom in video recording,in which I can take videos & photos horizontally & vertically.For eg I want to take photos of qutub minar.It is impossible to take photo of qutub minar coz it is very tall & my old camera cannot take videos & photos of so much tall & wide monuments like old fort & qutub minar.so plz tell me which camera is best for my requirements among these 3 cameras.If these cameras are not suitable u can mention another camera.pLZ DON'T mention SONY h SERIES & SLR CAMERAS.My budget is upto Rs 15000 & less
