I am very impressed with the Nikon D750. Yes, I believe this is a camera that could trigger a person to switch platforms. The thought ran through my mind for sure.
Positives: FF, Built-In WiFi, Dual SD card slots, Good AF, 24+ MP Sensor, 6.3fps
Negatives: 1/4000 shutter speed limit, Weather Sealing?
Neutral: Articulating Screen, Built-In Flash, ISO
This camera is going to be directly compared with the 5D MKIII as I think they are targeted for the same segment: Great all-around camera. The 7D MKII is a sports-shooter camera and APS-C. No comparison.
The 1/4000 shutter speed limit doesn't bother me. I checked my Lightroom database and found that shooting above 1/4000 represent .3% of all my images. Weather-sealing isn't a huge issue either. I simply don't expose my camera to elements that warrant it.
I did a couple of shoots lately which reminded me of how useful an articulating screen can be. Getting on the ground and using Live View without it is difficult. Using an articulating screen would be an enormous help and is enough for me instead of using a tablet and WiFi.
There are so many ways I can use this camera. I love my Canon 50D for it's speed and weight. I love the 5D MKII for it's FF sensor and color IQ. But they both have bad AF which is useful for events and sports photography I do. The fps equals my 50D which I find sufficient for sports. The sensor should be more than adequate for my fashion and portrait work. I love similar card dual memory slots. And at big events where there might be WiFi.. Uploading images in real-time and having someone edit and posting images in real-time?
All for under $2300.
The 5D MKIII wasn't enough for me. It's too expensive for what I get over the 5D MKII: AF & ISO No dual CF or SD slots and WiFi was a deal-breaker.
I think most of us would agree that the 5D MKIV is right around the corner. I'm going to wait to see what that looks like. If the MKIV has the features listed, I'm good and will go with that. I love the ergonomics and UI of Canon cameras. Not to mention the lenses and accessories available.
The only reason I really want a 1DX is that it can do everything I want to do. Unfortunately, even that doesn't have built-in WiFi and it's a $400 attachment. And that attachment looks like it may get in the way when shooting in portrait mode.
The Nikon gives me 85% of what I want from the 1DX. Buying a battery grip is a $400 option which then gets me up to 95%. I can certainly live without the crazy ISO and speed of the 1DX. At 40% of the price of the 1DX especially.
With the Nikon D750, it would certainly motivate me to eventually get a Nikon D810. Which is a superior fashion/portrait camera to anything Canon has right now. If the ergonomics are decent, I could live with the lesser UI from Nikon.
I'm going to try not buying any new Canon specific gear until I see the new cameras from Canon. Hopefully that should happen by early 2015.
I can only hope the buffer can handle a decent amount of photos in RAW. I LOVE my wife's D7100 but the buffer is terrible. You only get 7-8 shots max in RAW...
I think Nikon has a winner with this new body though.
