the more i research, the more i tend to be pushed towards Nikon... i was really excited about the A7R but the lens availability, ruggedness and price of the D810 is definitely the best option..
Price?
You can get a barely used A7R for $1000 on ebay, the cheapest I see a lightly used D810 is $2,200.
. i mean i need my body to be rugged. i camp, hike, expose it to weather... yes it has 18 less megapixels than the A7RII but it is a DSLR! and the battery life. just don't think mirror-less systems are ready for landscape photographers yet! don't get me wrong sony has come a LONG way but just not there yet i think. D810 is a huge upgrade to 6D in my mind.... my 2 cents.
That's interesting. For me, I wouldn't even consider a dSLR for landscape photography work over the A7R2 because of all the features the A7R2 has that are important to me in a landscape camera:
* No mirror slap when handheld
* EFCS works when handheld
* Accurate AF on the sensor
* More accurate MF with magnified view
* Built-in stabilization
* Smaller and lighter bodies
* Smaller and lighter normal and wide lenses, taking into account lens quality
Now part of the reason these features are all important to me is that I do a lot of handheld landscape photography. But part of the reason that I do a lot of handheld landscape photography is the fact that my cameras are much more stable handheld than dSLRs are. I can take a dozen or more handheld landscape images faster than I can set up the tripod and take a single tripod-mounted photo. And so I spend a lot more time discovering what compositions work with my subjects and light instead of fiddling with and moving a tripod around. For me, the dSLR is dead for landscape photography.
