Buy those old lenses and strap them on huh. Hmm, never heard that term used before to describe lenses. Hmmmm.
I tried an A7S once, shot at 6400ISO, I thought the it was 400ISO, it was THAT clean…
I thought until 6400 the S is pretty close to the other models and only from 6400 upwards really shows the muscles.
Not true at all.. U are Talking about Dynamic Range… In terms of noise there are worlds between the models.. Dunno how ppl can always make such statements
128k on the A7s looks like 1600 on the A6000 and about the same on the A7r -actually I havent tested it on the A7r that much so that might be closer to 1000.

Seems to be almost the same as A7R
Only when that’s what they want you to believe / think they are being very clever. There is a huge gulf between just about anything and the A7S (there are some exceptions but A7R definitely isn’t one of them).
A7S has a massive advantage in dark but they compare scenes in decent lighting where you wouldn’t need those high ISOs.
Talk about scewing results…
Yeah, sounds like a conspiracy against the A7S. They dared to turn on the city lights at midnight. Next time better shoot chimney sweepers in a cave.
My God,..that A7s is truly jaw dropping. It’s literally “freakish”. Those huge photosites are cranking out some very (relatively) “high voltage” pixels readings. I would LOVE for Sony to publish the signal to noise ratio of this sensor. 62 db? 65 or 70+db? I don’t know but damn that is amazing.
That guy is such an a**hat. He comes up with his own realities and makes videos in a clear and colloquial manner which makes it accessible to everyone and thats why he gets the hits and the followers, but if you challenge his assertions they usually fall apart.
I respect his type A personality for getting out there and making a living doing reviews but his information is generally 30% off the mark.
Do you have assertions to challenge here, or did you just log in to attack someone’s character and call it a day?
No, no i dont, not for you anyway.
Such snark
Much resent
Wow
Im so sorry for not satisfying you.
Mind your own business.
To the a7s owners: is AF that bad as in the clip?
Don’t know. I have two A7S and a Shogun, but never use AF when shooting video.
My A7s never shoot video… I basically use it as a still camera for even darkest conditions without tripod. The only native E-mount lens I use is the 28-70mm kit lens from the A7, but this lens isn’t the best AF performer anyway…. Everything else I use is A-mount with LAEA3 or LAEA4 adapter. For my needs (buildings, some landscape, some macro) AF is fine but especially for macro I usually use MF enjoying the focus peaking&magnification tools.
With the Sigma 70-200 /f2.8 (latest version with build-in OSS), AF with LE-EA4 is fast enough to catch my little daughter playing in the garden. So no problem there too. But definitely not usable for fast sports (running, cycling, motor sport) or if the subject is more or less moving “randomly” (e.g. soccer). Overall AF on A7s is slower than AF on my old a850.
AF is better (for me) than my old A850.
No
I have used the AF a couple times and definitely no. Can always use A-mounts with PDAF as well if needed for action, which actually works really quite well.
I like how he forgets to put the price of lens on the NX1 and A7S. Can you record anything without the lenses. Lol, The GH4 looks like the winner relative to its price and the A7S is self explanatory.
I can’t believe that he missed that there is a full range of very affordable Samyang Cine lenses for the A7S, considering it is a video review.
I’m quite surprised SAR nor readers have commented about the SEL2470Z tear down. Not just because of the mind-blowing reason of the failure found when doing the tear down, but about the suggested repair price tag from Sony that made LensRentals perform a tear down just-to-see and try to repair it themselves.
Sony is out of their minds if they think they can keep clients with such poor and unreliable design and charge them 800USD for that repair.
Now that along with the optical discrepancies of the lens itself…I’m not sure I will be buying this lens anytime soon.
So, pick one:
#teardowngate
#repaircostgate
#2470gate
I’d prefer #HaveNoClueHowToGlue
It’s clearly stated that this type of electromagnetic focusing is pretty new/uncommon, so this could be some kind of teething troubles. However I’m not trying to defend this, Sony should start a recall or at least replace faulty lenses for free.
really doubt Sony would recall anything. Just to take something as an example from the past, the mirror from the DSLR-A850 and DSLR-A900 was known to fall off due to the glue wearing off and Sony instead of coming up with free repairs, they wanted to charge 500USD (+150USD labor) to replace the entire mirror box assembly just for a glue that didn’t held the mirror in place.
At the end I did my own repair and glued the mirror back in place and it’s working great, but only thinking about giving Sony 500USD for a manufacturing defect is totally unnaceptable. Meanwhile in Canon land, even if the mirror from the 5D also fell off, they accepted to make repairs and modifications for free even with cameras out of warranty.
That wins long term customers.
Superglue I imagine right?
Some sort of superglue. Had to keep it ventilated for many hours.
Good to hear- hope it holds up. I’ve been looking to pick up a back-up a850. I read about that and had some reservations.
I’m not aware of the statistics relating to this lens failing (I haven’t read about any significant problems), so it’s a little unfair to suggest it is a poor and unreliable design.
I think Roger was reasonably balanced in his assessment, but only time will tell if his concerns about the glue are well founded. As StV has suggested, if it proves to be a weakspot then Sony should repair at no cost.
Of course, $800 for such a repair is quite ridiculous and Sony should look at it. Whether they have very limited facilities to do this type of repair (compared to Canon and Nikon), so costs are higher, I couldn’t say, although it will only alienate customers if they have to pay it! Should it turn out that this is a very reliable lens then the likelihood is most will simply buy another one as replacement after many years service.
The issue of copy variability is a separate thing and, I feel, prone to biased reporting. I’m not saying it doesn’t exist, but I don’t think it’s to the extent some would have us believe.
The AF-focus-system from NX1 in low light is terrible!
Specifically the AF-Tracking!!!
Yep! And it only has decent AF at all with like two lenses. Massively overrated. A7S may only have CDAF but it’s AF is solid in most light, plus you can use A-Mounts which track actually very well for video in say sport so long as you stick to your subject.
I personally cannot stand this guy’s reviews
Why?
I feel the same. I don’t know why, but I just want to punch him in the face.
I see. It must be because he has the look that says, “I got swagga.”
we all know the answer
Can’t deny that A7S sickness.
Is it too much to ask of these folks that do reviews to shoot the exact same thing using equivalent lenses and doing the same post processing or none at all?
So could you then pls explain what we can see here?

Sorry, didn’t realize it was rude to ask for elaboration on a publicly posted statement.
I eagerly await your book on Internet etiquette so I can keep myself from further offenses.
Are you a police officer administrator or just bored? You haven’t actually offered or contributed anything to the original post. If anything, you are as guilty as you think I am for making disparaging remarks about a ventured opinion.
sad thing is I have not used mine for still images at all …yet (other than first week testing in the house)
