Summary: The Nikon D3S, even as a previous model is a spectacular camera. It get's the job done and gets it done very well. It truly is a tool you can depend on and it stays out of your way. Yes, 12MP may seem low by today's standards of Megapixels but it is more than enough for 80% of all shooters. This camera just rocks! Unfortunately, many people are caught up with marketing ploys with larger, bigger, faster numbers.
Excerpt: This camera is my go-to workhorse. It has the focusing system and speed to shoot sports, and the low-light capability is simply unsurpased. It does everything I need a camera to do, and does it remarkably well. I've owned it for almost a year, and the only drawback is that is a bit heavy, especially if you shoot with it all day. I bought a mint D700 a few months ago, but find myself going back time after time to the D3s.
Summary: This professional camera is perfect for all situations: wedding, portrait, sport... I'm using Nikon products since 8 years, and they never failed. Solid, comfortable grip, no default for this camera.
Summary: This is the BEST camera i've owned. very solid, image quality is superb, quick and responsive, if you don't do video, this camera i feel handles better in low light performance than the D4. absolutely love this camera!
Summary: Newer cameras will always be released with new gizmos no doubt. This camera is the ultimate gear if you shook weddings, obviously great for portraits and other stuff too but am writing from the view of a wedding photographer. If you will shoot weddings in low light and super fast, this is the camera for you. I will be getting the D4 because honestly I can afford to and as a professional i need the new wireless features other than I am very satisfied with this baby.
Summary: I have had many Nikon Cameras over the past few years. Starting out with the D5000, D3100, D90, D7000, D700, D800 (currently own). I ended up selling my D7000 as once you hit ISO 3200 a ton of noise rears it's ugly head. Let alone the focusing accuracy on the D7000 is no where near as accurate as the Multi-Cam FX3500 (51 point) system. If you are a hobbyist the D7000 is a great camera for the money. If you are a pro or semi-pro this D3s camera will not disappoint.
