@Uhoh, Any idea what the EV sensitivity is with the LAEA4??
Somebody will chime in who understands how it works, I hope. I have LAEA1 & 2. What I can tell you is it's wicked fast, the 2, and works with a bunch of old minolta glass like the beercan as well. Technically you loose 1/3 of a stop, but real world impossible to tell.

DxOMark released their results for the E-M1 today and Sony managed to reduce High ISO read noise by about a 1/2 stop, which increases High ISO DR/shadow performance. If they can carry over that improvement to the A7(r) sensor then we should see a nice bump in High ISO vs the D600/D800.

Can you see the possibility that Nikon and Canon could be making cameras with larger sensors in order to keep their relevance as leaders
When I say larger I envision a sensor 50% larger than the full size they now have.

That is very interesting. I am curious how the 24-70 will do between the two formats. I expect it to hold up much better on the A7, but maybe not?
Do you see any particular pattern of what holds up better on the 7 versus the 5N?
there are lots of lenses that seem to perform bettter on the 7 versus the 5N due to extra pixels making most lenses look better, but it's the ones with a lot of spherical aberration that are surprising. some of them look kinda weak at the pixel level on the 5N and then look sharper at the pixel level on the 7. the lenses with weak corners on the 5N just have weaker corners on the 7 though. the rokkor 58/1.2, 40 cron, and 35 lux pre asph all look better on the 7. the jupiter-3 50/1.5 and most rokkor wide angles look better on the 5N.

I don't really always like IQ on 24 MP APS-C. It makes some optics that are perfectly good looking at lower resolution look bad. For example, some lenses that are great on D600 do not please me at all on D7100.
If you crop your D600 images to 10 MP and then scale them up to 24 MP, do they still look better then the D7100?
What about intelligently downsampling the D7100 to 10 MP and comparing to the cropped D600 image?

“DSLRs will diminish in market share and likely will become a niche product for wealthy enthusiasts. Mainstream enthusiasts will move to so-called mirrorless system cameras and the mass market will happily take pictures with their smartphones while uploading them in real-time to Facebook.”
So it seems to be time to sell your mirror gear before its worth nothing Kind of alarmist but probably slowly true over time. I mean Sony coming out with this camera and us being able to snap all of our favorite alt/Nikon/canon lenses on it seems like a perfect plan to take over the world.

Is anyone considering the A7 for the better AF at all? Or is everyone A7r or nothing?
I preordered the A7 - like others I have kids and even a little better AF is worth it. Plus I only have an Epson 3800 so I am not sure there is any benefit to the 36 mpix for me. Some stitched 24 mpix images will be enough for a pano.
I preordered the FE 35 as well. Everything I've seen from the 55 looks fantastic so I may need to get that as well.

a7r ISO does not disappoint, for first results anyway, jpegs - their assessment:
"You have to push the compact interchangeable ISO 1600 objectives to see the first effects of smoothing: the image loses teeth, but the details are still there and dynamics intact. Only finer details (material book for example) are dimmed.
In 3200, the smoothing is a bit stronger, but once again the treatment due to the image analysis (solid, edge, texture) works really well. The dynamic drop slightly, but nothing dramatic.
The transition to ISO 6400 is a milestone. The overall image is a little more dense, fine details are blunt and the rolling becomes more easily visible at 100% on screen. Chromatic noise is content and images are still easily exploitable.
Fairly astonishing images to ISO 12800 are a bit more pleasing. Emphasis is further than 6400 and an HDTV screen image looks more detailed (which is not the case)."
Looks like some nasty light, and utter lack of forsight by the reporter has given us images of a lens we already know is good which make it look less than it is---well peepin is OK I guess.
The guy could not throw some RF glass into his packet and give us a bone or 2?
