I too have a bridge camera......Lumix Z18,had it for 3 or 4 yrs now . I find it perfect for my needs and as we walk alot.not too heavy.My BIL has new Lumix DSLR,it is great but mine has many of the same features at a fraction of the cost.
He can get closer and sharper shots of birds and wildlife when he uses a (massive!
) different lens.
