Ummm, this is the Canon forum/thread for people that presumably have Canon cameras and lenses which they might wish to use on the new Sony A7 series. Maybe most of us won't have Sony chargers - will we?
Given the preponderance of Nikon and Canon cameras, as many as 98 percent of the potential new users of the A7 series likely won't have Sony cameras - and if the only buyers are existing Sony owners with Sony chargers, their market is greatly reduced.
To me, that isn't the relevant point. The camera will be used in a way that will require an external charger for almost all users. The battery life is very short and the charging time is very long if you are only using the internal charger. They should include the accessories needed to use the camera properly. It is different than not including extra cables to connect to a tv or including a card reader with a camera. Those aren't needed by everyone, are more universal and are easy to pick up depending on each persons specific needs. But a charger is very specific to a camera/battery and is needed for the vast majority of users.
232 reviews - 4.5 stars out of 5, ~$27, "problem" solved. You still have a 24 or 36 MP camera with one of the best sensors around, for a very reasonable price.
For my RX100, the batteries have a little less power than OEM batteries but are about 80-90% in comparison. Charger works great with OEM batteries and car adapter is included as well.

People are still whining about the battery and charger? Is that $30 item the only thing you can find to complain about the Sony? Indeed, and it speaks for the amazing value of this little Canon killer. As already posted several times in this thread, you can get 2 batteries and a charger for less than $30.
There's something called a google search, try it yourself.

On Saturday I picked up my a7r.
Here are my first impressions and some sample pictures:
1) It yields higher resolution based on my pixel peeping
2) It works fine as far as I can tell with my ts17 and ts24 which is the main reason I bought it to match with. I was worried that the edge fixes sony had implemented to fix extreme light angles might help rangerfinder lens but hurt regular lens. I could not find any distortion from this affect. So it passed the most important challenge for me. Including shifting to extremes and merging.
3) All my zeiss lens worked great 25/2, 15/2.8, 35/1.4. In fact I think with less vignetting. So again, it did great on with my eos mount zeiss's. No visible vignetting.
4) All my ef lens that I tried worked - 24-105 focussed and stabilized, 100-400 focussed and stabilized, 24-70 v1 focussed, 17-40L focusses, 70-300 5.6 focussed and stabilized, 50/1.8 (but no focus). I used with metabones III. But it seemed really slow to focus. My impression is a bit slower but comparable to than the same lens on my eosm with adapter. The 85/1.8v2 worked but it would only permit me to go to f1.3 not f1.2 - strange.
5) As expected it chews batteries. I can get 1000 or more pictures with 5diii but way less on a7r.
6) It features feel like the Russion version of the 5diii. It all works but not smoothly
- it seems to have more vibration on shutter release than the 5diii on mirror lockup.
- it does not time off to save battery easily or at least I have not found it easily
- I found a infared remote shutter release for alpha and of course I can't get it to work
- finding the magnify on liveview was tiresome - the manual is useless and cryptic
- I cannot sync for remote shutter release with my iphone 4s - don't know if not supported or just can't figure out - no manual
- The canon wired remote shutter has an easy plug in. The sony equivalent feels like it will break at first slight touch. Ditto on sd card cover and battery cover.
7) The liveview focus did not seem to have a much resolution as my 5diii. Could be wrong.
8) The histogram implemenation is way too small compared to the 5diii and thus it makes it difficult to get the exposure right wthout multiple trys
9) You can download the sony raw image processor. It works and stops working randomly. Mac Tower 8core, 32GB 10.6. I don't know why but it is frustrating. Eventually you will get through the conversions if you restart from where it stops and freezes. Aperture does not have raw converter yet. Nor does cs6.
10) There is no red light to indicate you are in the middle of a long exposure. In addition its hard to tell where you are in the sequence when you do an AEB - 3 AEB sort of makes a galloping noise and you have to hold it down to the end for it to complete its cycle. The 5diii was more intuitive with a red light on during exposure and 1 noise per shutter.
11) As noted elsewhere, using an L plate to be able to shoot portrait and landscape without turning the tripod head sideways, is yet to be perfected. The generic L plate I found, did not permit the body to be taken off the adapter because the turned body was too close to the L plate. Having to srew the l plate on and off to use the camera without the L plate is a pain. I have ordered a spacer for the adapter to give it more height and hopefull this solves my problem. This will be solved soon by someone responding to the market (Kirk, RRS, ...:?) but as of now, its not clear who.

Zeiss 25/2 with canon mount - teaching my son to drive
Canon cheap 50 1.8 - would not focus auto with metabones
Canon 24-105 focussed and IS'd
Zeiss
Canon 85 1.2 - strangley it would not go down to f1.2 on the a7r

Thanks for sharing your first results- and if the EOS-M seems fast to focus in comparison...
It is comparable in speed in focus when comparing focus speed on eos-m with adapter and ef lens to a7r with metabones ef adapter. eg 3seconds vs 2 seconds to focus from near 3' to 8' on sony a7r vs canon eosm respectively. [vs <1/2 second for 5diii]
I repeated the experiment with my 70-200 2.8 IS. <1/2s for 5diii, about 1s for EOSm, about 2s for a7r but only 50% of the time reaching focus.
In other words with ef lens and metabones adapter - only good for stills or manual focus lens.

Scott,
Did you try using the adapter tripod mount? Did you use the L-bracket on it?
If so, were you able to work with the TS-E lenses?
Fred
I am still waiting for the spacer that I ordered for my metabones to arrive by mail. I will report.

Yes, the Sony lacks electronic first curtain shutter, which is poor form. Canon 1D IV was heavily criticised for this omission. The A7, however, does have EFCS.

"According to bullet proof sources the A77 will have a very short release time lag thanks to a sort of “electronic first shutter curtain“. Michael Covington’s website explains what it is. The electornic first shutter curtain begins the exposure electronically with zero vibration: “In fact, as I understand it, the “electronic first shutter curtain” is a virtual moving edge just like the real shutter curtain, so you can use it even with short exposures. Columns of the sensor are turned on one by one just as if the real curtain were exposing them. Because a CMOS sensor can’t turn off as quickly as it turns on, the real shutter curtain is used to end the exposure.”
I don't get why a vibration at the end is less important than a vibration at the begginning. I guess if the harmonic dampening is cut off by a very fast 2nd shutter this is better than the begginning. But it suggests that if you are shooting a sequence of 3 (AEB) that the 2nd and 3rd image could be affected by the 2nd shutter from 1st and 2nd, depening on the time between shots and the dampening.So if this is true - maybe it is introducing vibration after the exposure instead of before it. It still strikes me as more vibration at end then 5diii with live view or mirror lockup

Coming from someone that have made 15 post. And only write Canon Killer in everyone Yes I'm sure Canon will be out of business in a month or two
Probably more than 99% don't own a charger. So it would be very strange to not care about all those people.
