p.19 #1 · Sony A7 and A7r Full Frame with Canon Lenses


The 50L should shine on these bodies. Magnified view and focus peaking mean precise focus nearly 100% of the time, even at f/1.2. 36MP for squeezing out a little extra sharpness wide-open will help as well.

f/1.2 would not be the primary concern. Won't it still suffer from focus shift?

Yes, since this would be a lens-specific issue, not camera-specific. Personally I have never observed this focus shift issue with my 50/1.2.

I don't notice any focus shift on my copy but it wouldn't be a problem anyway since you can focus stopped-down if desired.

Lots of 24.3MP A7 shots uploaded on Flickr: http://www.flickr.com/search/?q=Sony+A7 most Zeiss and Leica lenses but no EF sample yet. Sorry for the image size, they look better this way so you can judge them.

DR samples look so fine, highlights shadows transition look very smooth. Pleasant IQ and AF is not bad either

hardly to see noise nor banding. Click for 100%: [url=http://farm8.staticflickr.com/7356/10381966724_60224fcd1f_o.jpg

I[/url] don't see any canon cam can beat A7's IQ, let-a-lone A7r. Same performance just like D60X and D800(e)



Really looking like a gorgeous sensor! I'd like to see someone push the shadows a little to see what this baby can do.

No, the one with the element is the Speedbooster.....it's like a reverse teleconverter to take the full frame size image and reduce it to APS-C. You gain light in the process. That wouldn't make sense for a full frame sensor.

The normal Smart Adapter (III) just puts enough space between the lens and the sensor to mimic the distance it would have on a normal camera with a mirror. There is no light loss.

Okay, guys, I was a while offline because I was outside and actually taking photos with my 5D MkII cameras . I recommend we all enjoy the beautiful fall weather (where ever this is possible climate-wise).

I have a question in regard to the Metabones adapter which can be used with the A7(R) cameras: it looks like there could be potentially two of them used with Canon EF lenses, one with the glass element (improving the lens speed by one stop indirectly by its built) and the other MkII/III(?) one which functions just like an extension tube without glass element.

Thanks for your reply! I wanted to make sure that there is no light loss. Makes sense since the adapter just compensates for the missing sensor plane-lens distance. I just wasn't sure if this adapter has exactly the length to compensate for the Canon camera lens-sensor plane distance.

Yup, that's the one you want...version III of the EF to E Smart Adapter.

hopefully canon takes note of threads like these and gives you guys a FF body w/ a high res sensor...

this thread is kind of sad: lots of people invested in canon glass that are so dissatisfied w/ current canon offerings that they're willing to go w/ an entirely new brand as long as they can use their lenses...

Too sharp, no. Too much sharpening in post, yes.

I'm interested in the native E mount lenses too. It's nice to be able to explore other brands without having to do a wholesale switch.

Don't forget most of those sample shooting with fast lens 55mmf1.8. You can tell the images sharpness by reading their original 100% crop from Flickr

I can't wait on this one or any fast lenses from canon. Bokeh & colors shall be in another dimension

I see it as a great thing and perhaps a significant inflection point in the industry. Putting aside the inability to AF (or at least AF quickly), the idea that a photographer can match best-of-class lenses from Canikon to a third-party FF body is pretty amazing. Photographers have learned to take the lack of interoperability for granted but it's pretty ridiculous when you think about it. I wouldn't expect Canikon to make an interchangeable body like the A7/A7r but certainly Sony will hold their feet to the fire to keep them innovating on their own bodies now that the locked-in-system premium is tossed out the window.

Not sure what you think the big deal is here? Ever since we've had mirrorless cameras we've had to ability to use virtually any lens and adapter combo. Now we can do it with FF sure, but it was Olympus and Panasonic that got the ball rolling with the m4/3 cameras in the first place, then the others followed suit.

I'm not that clued up about the EOS M but I can't see why you can't adapt alt glass that to that. The only think Canikon need to do is take mirrorless more seriously and offer a range of sensor formats from APS-C to FF.

Sony cross platform competition is a great news for all shooters. We will have more quality product based on price, selection, and service from now on.

With a few exceptions FF-format lenses aren't well suited to smaller sensors because they lack the per-area sharpness of their smaller-format equivalents (not to mention having a different FOV). Regarding the EOS-M, adapting a Canon lens to another Canon body doesn't address the interoperability need with other body/sensor technologies.

You can't put aside the inability to AF (or having good/fast AF). And even attach your lenses without buying converters.
And very very few lenses from Canon are best of it's class when you take away the tele lenses which are not good with adapters and no AF. So why not go all the way and upgrade both sensor and lenses to best in it's class
It's fun to read all these threads about the new Sony cameras. And about all the people that will change from their Canon body to these new cameras. Because their Canon sensor is not good enough. And then you see what lenses the use and what lenses they gonna adapt to their new camera.
(I'm probably buying the A7R) And it's probably a great thing as you wrote. But except from a few unique Canon lenses like the TS-E very very few are best-of-class when you take away the long tele lenses. I belive this new camera will be much better for the people that already use MF lenses.

Mirrorless movement is just the beginning of Sony game plan. They got the film that everyone wants it. No one dare to make this move when canon is on top of their sensor game. Seem like, they want everyone buying their sensor. They currently build the bridge to close that gap.
