indusbreed: This dude tested the A7r II AND is trashing its auto focus in low light. The trick being that it is using the focus assists beam to focus in low light. If you disable that, it becomes pretty much useless.https://www.youtube.com/watch?v=XxxKAJtBnhA
He is using F4 lens. DPR article is talking about performance with faster lenses (F2 and faster) where A7RII's AF is same or better in lowlight than top DSLRs.
aftab: Rishi, you know well that you have drawn a broad conclusion based on one test using a specific lens and aperture. To draw such a conclusion you need to use variety of lenses, different bodies, different FLs and subjects etc. At the end you may be proven to be right though, but for now your conclusion applies only to this specific situation.
Many other lenses were tested, according to Rishi comments.
Roland Schulz: Ok folks, nice test, but not completely honest: The Sony may beat Nikon´s or Canon´s best AF systems in low light using a F1.4 lens, but that´s only half the truth for wedding photographers that often take F2.8 zooms or even F4.0 to be more versatile. I bet Nikon and even Canon run´s smoking circles around the Sony using F4.0 zooms – why? Simply because common dSLR phase detect AF systems work with an internal let´s say F8 AF system, result is that lenses up to F8 doesn´t alter the AF performance. Not so with the Sony, here the AF system hitting light is limited only by the lens, but a hefty F5.6 500mm telezoom would influence the AF by 4 stops where Nikon and Canon work as before. This fact wasn´t “pronounced” in this video. So maybe the A7RII´s AF is not the holy grail for some (many) folks. Would really be nice to see a comparison with F4 lenses!!
On the other hand on sensor AF has many advantages as described, compared to dSLRs there will hardly be a front-/backfocus.
"but a hefty F5.6 500mm telezoom would influence the AF by 4 stops where Nikon and Canon work as before"
That's not true. AF will suffer on a DSLR too. A F4 lens will AF better than F5.6 lens on a DSLR in lowlight.
nikheat: Yes, but still no mirrorless A-mount!!!!!!!!!!!!!!!!!!
MacroBokeh, K01 did not have on sensor PDAF and AF was not better than a DSLR in live view of the time. There was no EVF, no tilting screen. Ergonomics were bad.
The hate had nothing to do with looks. Read the K01 review.
Lightcapture: With bright lens. Yes. That's good. Tony Northrup did a 70-200 native lens low light continuous AF shootouts with the Canon 5DS and the Nikon 810 (I think as well), and the conditions wasn't as dim as what Rishi was testing in the video shown above. And we saw the Sony did really badly in that test. I know the lens they use isn't the fast lens, but why could the same native lenses under bright outdoor conditions did so well for Sony (which significantly outperforms its competitors) while indoors it's the complete opposite?
"Knowing the geeky Tony (not as geeky as Rishi granted), he'll shoot them in the same aperture even if one lens is faster than the other."
That's not how AF works on a DSLR. Even if you use F4 on a dSLR, the lens will open to F2.8 to AF and step down to F4 to take a shot.
Besides, read this DSPR article. A7RII apparently needs light (or bright lens) otherwise it switches to CDAF only.
57even: Actually looks like a nice bit of industrial design, particularly the switches and buttons.
I didn't realise the camera wasn't weather sealed. A little surprised at that for a landscape/outdoor camera.
Digimat post was reasonable. Yours was not. That's because you are a M4/3 troll who has a history of posting nonsense with several accounts (includes banned accounts like Everdog, JustHavingFun, etc and several other active accounts that aren't banned).
A7R is weather resistant.
Operator: Compare it with the PSP tear down:https://www.ifixit.com/Teardown/PSP+1000+Teardown/1234
IMHO the A7r II is consumer class electronic sold for a premium price. Not built to last.
A7R had magnesium shell
Long story short, A7RII is weather resistant. That's official specs of the camera, regardless of what a M4/3 troll claims.
Funny I have never seen any Pentax camera with IP rating, but they are all called WR by DPreview
Typical M4/3 troll (and yes, he is everdog sock puppet).
A7RII is dust and moisture resistant. That's official specs of the camera.
I looked at his guy's history (bluevellet ) and he appears to be just another sock puppet of old m4/3 troll called Everdog , Just_Having_Fun.
This by the way isn't his only account.
Your rambling is totally irrelevant. Sony officially claims the camera is dust and moisture resistant. Weather it's good or bad WR is totally irrelevant. There is some WR on the camera, unlike what you said
It's weather sealed
misha marinsky4: Popular Photography used to do this. For example, March 1981, pages 108, 120, and 121.
Also, keep in mind that a digital camera in reality is a computer with a lens. If it breaks after two years, it's not worth fixing. 99% of the chips will be obsolete.
A camera isn't a computer. Forget two years, even a five sensor in K-5 (2010) is still not that much worse from 2015 sensors.
Even worse, Moore's law is dying even when it comes to computers. The computers aren't getting that fast as they used to a few years back. Look at the top 500 supercomputers. This list isn't changing as rapidly as it used to change. In fact, except one, all top 10 supercomputers right now are older than 2014 (bunch from 2013, one 2012 and one 2011)
It is weather sealed
firstname.lastname@example.org: The Nikon mirror up is ideal for me. Raise the mirror. Take the shot at the right moment.
OVF on a DSLR doesn't work when the mirror is up.
Where are the studio shots?
win39: What is it with the sound? I can barely hear it with the volume turned all the way up.
It's loud and clear even though my volume is less than half (1/4) . I use headphones though.
Don Sata: There is no way the cover photo (sun through forest sky) could have been achieved in a single shot with another sensor than a Sony, the wide DR allows to preserve highlights and recover decent shadows.
Toshiba and Sony shares facilities, so this so called "Toshiba" sensor is just same 24 MP sensor made in Toshiba factory.
Why no studio still shots for video?
ogl: It seems to me only sensor business helps SONY to live.
"I've heard camera business is not profitable."
You did not "hear" it. You made it up. The camera business has been profitable for a while now
