I would not miss seeing Crater Lake National Park if you are anywhere in the vicinity.  Simply breathtaking,  weather can be interesting in Fall so check ahead.

I'd rather pay $899 and get a full warranty and a for sure real copy from Amazon, Peace of mind is worth way more than 41 dollars saved

The regular use won't care a whit about 4k vs UHD and UHD is actually better for them, if anything.
A7S+Shogun costs like 1/3 the price of a 1DC.


You forgot to add that the Shogun has a 7" screen.

Why is UHD better for "them"?

Isn't most movies shot on 70mm film better than 4K?
You know those huge Panavision cameras?

I have shot once in 4K with a friend, we rented the RED Epic. The end product was sh!t, don't tell the talent that >>> http://www.youtube.com/watch?v=09Su2qxm8ik

"You can pick an A7r up for as little as $1700 used, A7s' used for as little as $2000."

Ever wondered why these owners are selling?

You can find anything used. And I was actually having trouble finding all that many A7R and A7S for sale. On FM there have been but very few, etc.

A7s can't record internal 4K, and as per dpreview external isn't even cinema 4K, its UHD (max 3840 x 2160 @ 8bit). http://www.dpreview.com/previews/panasonic-dmc-gh4-sony-alpha-7s

GH4 is better with both cinema 4K (4096 x 2160) internal & external (10-bit), only problem is that its micro 4/3rd sensor.

"It sounds like there will be a retractable opening near where a filter would be, so you could turn your circular polarize easily if you needed to."

Pretty cool. I could sure use that with the 70-300L.

Roger was responding to the posts about loosening the mount screws to simulate the issue.  He said that loosening the screws will always cause it to happen and I agree.
 

Umm - What Cicala wrote, titling his response "Shame on you Fotodiox" was this:

"For loosening the screws in their demo camera before making that video. We've got dozens and dozens of A7s and I'd never seen flex like that. But if I loosened each mounting screw 1/2 turn, I got flex exactly like that."

(Lots of other sensible-looking posts in that thread too.)  I think msm's perspective is quite plausible.  There may be some problematic bodies (I have no idea, but Cicala has seen more than probably anyone else), but it's not at all clear what "the issue" was that people were complaining about - slight rotational play, clueless mishandling or something else, let alone whether any mere "wriggling" had any effect whatever on the images produced.  The idea that Fotodiox is responding to demand rather than trying to create it by exploiting internet chitchat is a tad naive (even if they were it's not clear exactly what the demand is or whether this will satisfy it).  And based on my experience with their lens adapters - usually perfectly fine except sometimes with inaccurate infinity stops - I doubt Fotodiox are the last word in mechanical finesse and I certainly won't be buying one of these things for my A7r or A6000 (nor, when I attach my 70-300L to either one, would it occur to me to pick the combination up by the body...).

The 400 5.6 prime beats them all, canon 100-400, sigma zooms, whatever.

Not mine, and not the various test lenses.  For all practical purposes, they are the same, except for the IS and close focusing of the 100-400.
And focusing speed?

A midrange zoom isn't supposed to "beat" a prime because unless you're focal length limited. With the zoom you can get the optimal sensor coverage meaning less noise and more sharpness because of less nr. With a prime, what do you do if your subject decides to get near you? Quickly switch to the 300L, 200L and 100L?

I never run into a situation where the bird did not fit with the 400 prime. But I am not the waiting type, I am the walking type, and shoot whatever appears. So, the 400 prime is perfect, light and fast focusing.
If the bird is still, it always fits the image, no matter how close. If the bird is flying very close, it moves too fast for me to be able to frame it, and zooming will only make the process slower, not to mention the AF would be slower too.  It is better to shoot farther, as the focus will be better, and still close enough to get zero image degradation.
