DxOmark shows the Sony A35 sensor results (is as good as the A55)
Image source: DxOmark.
You can read the latest A35 sensor review at DxOmark (Click here). As you can see from the overalls core the A35 performs as well as the more expensive Sony A55 but not as good as the last of all Sony DSRL cameras with OVF, the A580! This will bring some flame in the never ending Optica versus Electronic viewfinder rebate!
See the full detailed A35 vs A580 vs A55 comparison (Click here).
And check the mentioned camera availability and price:
A35 should be in Stock soon at Amazon, Adorama, B&H, J&R, eBay (Click on shop names)
A55 recently saw some nice price drop at Amazon, Adorama, B&H, J&R, eBay (Click on shop names)
A580 for all OVF lovers at Amazon, Adorama, B&H, J&R, eBay (Click on shop names)

10 months ago |So…is a bigger view and always-on autofocus worth the drop in battery life and (minor) hit in image quality? The debate continues….
Personally, I’d like it if Sony would continue to produce newer OVF models – both designs have their advantages.

10 months ago |We have nothing to say in regards to what technology will be used in the future camreas. Whatever brings in the profits is what we’ll have to live with.
On the other hand, the APS-C OVF DSLRs are a joke. They are oversized relative to the sensor dimensions. They use oversized lenses. The tiny OVFs provide the same experience as looking through a key-hole. It would be in the best interest of the mankind to earse these pathetic things from the history of digital photography.
Leave the OVFs where they belong – in 35mm sensor cameras where they are large, bright and provide an immersive experience like no other.

10 months ago |I do find some APS-C OVF’s acceptable (such as the one in the Canon 7D); but by in large, yes, most are horrible. Especially all forms of the pentamirror’s…and in the APS-C world Sony seemed to produce the worst (probably due to their live view system). So for APS-C I won’t miss the OVF at all, but it will be a real shame if the A900 successor does away with that beautiful view finder.

10 months ago |The A55/A580/D7000 comparison is well known – is wholly consistent with a 1/3rd stop difference. That is that the DR & SNR you will see on a D7000 or A580 at 1600 will be about what you would see on the A55 at 1300 ISO. For the vast majority of photos, that won’t make any difference. However, if you do regularly shoot at 3200+ and want largish images then you might. But for the great majority of people in the great majority of cases, it simply won’t be visible. What will be more important for most is whether the SLT makes it easier or otherwise to capture images, maintain focus, get the settings right, identifying clipping, do the framing, get the horizontals right and all those myriad of other things.

10 months ago |I hope the 24mp sensor performs well. I can’t believe Sony could have made it Better Quality / Sensitivity and upped the MP too…. we’ll see I guess.

What does VF have anything to do with picture quality ?
Futile
10 months ago |In this senario the Sensitivity of the Sensor is compromised by 1/3rd stop to allow the EVF to work without moving the mirror. When the photo is taken you lose 1/3rd stop of light, so the resulting image is affected.
This is Sony’s implementation of EVF with Phase Detection Focusing.

10 months ago |Don’t make such a big deal out of 1/3rd of a stop. It really is insignificant in the real World.

10 months ago |I’m a still photographer, one image at a time (unless I’m bracketing for HDR) and don’t care about video, although I’m happy that others do, and I don’t care that it’s a feature on a camera I purchase.
The image quality is very important and I’m will to pay more for my camera and if necessary work harder to get the picture if I need to.
I also really like my 24MP a850; paired with my CZ135/f1.8 and with Photoshop I can enlarge my prints and get better detail than if I was shooting at 200mm with my 70-200/f2.8
High MP + sharp optics = bigger prints without bigger lenses!
I see many benefits to the EVF, but if it produces even a slight loss in image quality I’ll just find a OVF from someone else and continue my photography using that platform.

10 months ago |Sony has confirmed that they will be launching only EVF cameras henceforth so you may be a bit out of luck.
If you care about sharpness and detail then you must be using the default ISO or close to it since the A850 has poor high ISO performance.
In that case I doubt you will find any difference in the IQ of the OVF based Sony A580 and the EVF based Sony A55.
Its only when you pump the ISO to 1600 and above that slight differences crop up.
Futile
10 months ago |I’m not sure it’s a reduction in Image Quality, but more a compromise of Sensitivity.. If you are a High ISO shooter it should be more of a concern for you.
Technology moves pretty fast, but standards rarely change. I think there is an agreeable level of Image Quality that will always be, and technology is really being used to make things easier, faster, smaller etc…. My guess is that this 24mp APS-C sensor will probably get you same Image Quality your used to (little or no improvements on that front), but what you will get is 24mp in a smaller body, Good AF with EVF, Video, etc….
It might not be what everyone wants, but I’ve seen it time and time again. Once a Level of Acceptability is set, its rare that the bar ever gets risen.
I’d be surprised to see decent ISO quality above what the NEX5 is pumping out, but its possible as technology is getting better. I’ll be happy with anything close to my A700 performance.

10 months ago |That’s continious phase autofocus that leads to slight loss, not an EVF.

If true, it’ll be the first 24/1.4 in Alpha mount from anybody.
redfern
10 months ago |Nice find, Carl. Through a mount adapter, this might be a viable and faster alternative to the Zeiss 24/1.8 coming for the NEX.

10 months ago |It’s not an EVF vs. OVF thing; it’s a semi-translucent vs. open air thing. The A55′s glass only reflects 30% of the light, but it doesn’t get out of the way when you take the shot. So, only 70% of light is hitting the sensor vs. 100% with the OVF system. As Steve Jones pointed out, that’s about a 1/3 stop worse in DR and low-light performance. However, take the mirror out completely and run the EVF off the sensor, then the sensor score will be the same as with an OVF. It’s Sony’s implementation of the EVF, here, that is causing the change in scores, not a universal problem with all EVF systems.

10 months ago |One thing I’ve noticed with dxomark is that the results from using the same sensor on different cameras is very consistent, usually around 1 point between them, suggesting the error on their measurements is well controlled.
DrSmouse
10 months ago |It’s also differences in the camera processing engines.
David
10 months ago |Everybody stop whining.
You would never notice the difference between two pictures with 1/3 stop noise difference, so stop making a massive deal out of this.
And for those of you with uppity attitudes, why are you even shooting an APS-C camera? If ultimate dynamic range is your concern, you should be on AT LEAST full frame, if not medium or large format.
Technology is improving at an amazing rate. Entry level dslrs from 2011 outperform professional dslrs from less than 10 years ago. Each generation gets significantly better too. Look at the a550 to a580 improvement.
The EVF adds far more benefits that outweigh this hypothetical 1/3 stop loss, which will be easily compensated for by better technology, better software, noise reduction etc.
And as someone said, most APS-C viewfinders are awful, tiny and dark, so they shouldn’t be missed at all.

First EVF’s, then the grumblings will be about touchscreens.
Mullah
10 months ago |What kind of excisting SD-card can utilize 1080 60p 28mbps without being a bottleneck?
Steve Jones
10 months ago |Lots of them – it’s 28 megabits per second. Class 10 sdhc cards ar all god for at least 10 MBytes/sec or 80 megabits per second. Many are a lot faster.
It’s the demands of a 12 frame per second 24MPIX still camera that are far, far higher. That could easily top 1.6Gbits/sec or 200 Megabytes/sec using RAW. Even JPEG could approach 1Gbit/sec (that’s assuming the 12FPS is full res).
Video files are simultaneously much lower resolution than still whilst being much more compressed (at least outside highest end kit).
So the answer is, the video files can be dealt with easily, but the endurance of the burst performance on the A77 is going to be limited by the size of the buffer.
