I used Final Cut Pro/Final Cut Studio for years. When Apple switched to Final Cut Pro X I was really shocked with this vivid downgrade. But 3+ years later, with a lot of professional feathers added to the early version of FCP X, I came to conclusion that workflow in this 'downgraded' program is fast and comfortable, and practically nothing of abilities is lost (and a lot useful is added). I hope after several upgrades Photos will become closer to Aperture than in this early version. What I like in Photos right now — it's speed and automatic synchronization with iPad/iPhone library. But I'll wait for upgrades of Photos — using Aperture as long as I'll be able to to this.
For Windows only... It means — useless program for the most of photographers.
I purchased P7700 as a Christmas gift to my wife to replace her old 'travelling' compact camera and was so impressed with it's image and build quality that I came to conclusion to leave it to my own needs. (My wife received instead P510 and happy with it).
P7700 is able to replace in most of situations including low light conditions (up to ISO 1600-3200) any enthusiast level DSLR (like D7000 or Canon 7D). It is practically much much better than one could expect from it's price. But you need to pay additionally for fast card (like Lexar Professional x400 or faster) and high quality protective filter 40,5 mm.
Upgrade of iMovie to professional level. Really good for broadcasting, especially for news reels. Fast and easy!
But for any kind of film/video production it's an obvious downgrade.
