It's currently £450 upwards which is rather steep for a 2015 model.
I paid £295 nearly 3 years ago on a special offer from Amazon.
The spec sounds impressive but the actual lens sharpness etc. is probably not as good as my more pocketable Nikon P530 that cost £179.
The only thing that is superior is the 4K video it shoots as the Nikon is only 1080p.
However, when shooting 1080p video, the FZ300's sharpness is poor for some reason. To begin with I thought maybe it was my particular camera but a web search revealed that every other FZ300 was the same.
Don't get me wrong . . . viewed in isolation, the 1080p looks OK but if you compare its results side by side with the Nikon or my Panasonic SD800 camcorder the inferiority is glaringly obvious. (Just in case you are wondering, I did spend ages testing every possible version of mp4 and AVCHD it provides, to no avail).
I assume the problem lies somewhere in the way the 12 megapixel sensor down-converts the video to 1080p.
