(SR5) A77 with ISO 50 to 16.000. A65 can do almost the same as the A77.
I now have been told the A77 can go from 100 to 16.000 ISO and has the ability to shot even at 50 ISO if you need it. As you know the new sensor will feature a 24,3 Megapixel sensor. If you wonder about the A77 and A65 differences than I can tell you that:
1) A77 has 19 point AF system with 11 cross sensors while the A65 has only 3 cross sensors.
2) A77 can do 12 fps while the A65 can do 10fps.
3) A77 has new 3 way tilting LCD, A65 has “classic” tilting LCD
4) A77 can do 50 ISO while A65 can not.
5) The A77 has a magnesium body while the A65 has not.
6) The A77 has 1/8000 shutter while A65 has a 1/4000 shutter
7) The A77 has a top LCD screen while the A65 has it not.
8 ) The A77 is Dust and Moisture proof while the A65 is not
There are also other small differences but those are the most important ones. As you already know the A77 and A65 (and the NEX-7) do share the same 24 Megapixel sensor, same 3 million dot OLED viewfinder. Price is:
- Sony Alpha 77 + 16-50mm f/2.8 SSM = 1800€
- Sony Alpha 77 body only = 1050€
- Sony Alpha 65 + 18-55mm f/3.5-5.6 SAM = 1000€
- Sony Alpha 65 body only = 900€
And that’s the competition price:

Is APS-C SLT is just equivalent to 4/3 SLR?
I mean comparing light loss via translucent mirror or loss via sensor surface reduction.
Steve Jones
2 years ago |If you take the simple approach of the number of photons that reach the surface and say that is directly proportional to sensor area adjusted for light-loss on an SLT you get the following
Micro 4/3rds: 18mm x 13.5mm = 243 sq mm
APS-C (using A55 sensor dimensions): 23.5 x 15.6 = 366.6 sq mm
If we now take two-thirds of the latter, this would then be 244.4 effective sq mm.
On that rather crude basis, then a micro 4/3rd sensor will be roughly equivalent to an SLT-equipped APS-C assuming that the sensor technologies are comparable.
However, that isn’t the full story. The larger sensor still has larger photo-sites, deeper electron wells and at base ISO should be capable of better performance. Indeed if you go to DXOMark and compare the A55 with the best of the 4/3rds system cameras, the high ISO performance of the Sony is only a little bit better on SNR & DR. However, at lower ISOs the A55 has as much as 2 more stops of DR, quite probably because it can hold onto highlights better without saturating.
So, I would expect the A77 to comfortably outperform any micro 4/3rds system. I suspect it will have better SNR and DR throughput the ISO range with a much larger DR at lower ISO settings.

16000 = unusable at all
8000 = emergency purposes, still crap
4000 = usable

2 years ago |Many thanks for the clarifications Steve.
I was afraid that this pellicle mirror technology is really a limitation… Seems not that much… At least not as much as dropping performances to a lower category sensor.

2 years ago |Hey, i’m in love with Photography and I want a Sony Slt to be my first “real” camera. I am thinking about the a65 and i am wondering whether it is a good camera for beginners or not. I want to try out and play with aperature and shutter speed to be crative ;-D Do you think a65 would be the right one for me or any other camera?!

2 years ago |Probably overkill, but that isn’t necessarily a bad thing, as you can grow into it.
Just make sure you also budget for at least one properly good lens to go with it

2 years ago |Or consider an older Sony camera. a700 is a good camera and cheaper.

2 years ago |Consider A580. It isn’t too expensive, old school OVF plus very good high ISO (same image quality as a 7D, so that is what some people are saying on the web).

2 years ago |I think that many of us are forgetting, or taking for granted, the effect of SSS relative to other brands, in this high ISO discussion.
Folks have complained in the past about the relatively poor high-ISO capabilities of the Sony line in general, when compared to Canon and especially Nikon. However, it was never truly apples-to-apples unless using a stabilized lens on these other brands. For example, even with a mild two-stop effective in-body stabilization, at the same aperture and shutter-speed combination my Sony could shoot at ISO 800, for example, rather than ISO 3200 with the others.
So even with ISO 12,800 (leaving the ISO 16,000 out of the equation for a moment) and two stops’ stabilization, that’s equivalent to ISO 51,200 on another camera that doesn’t use a stabilized lens, if we wish to compose a photo at the same aperture and shutter speed.
I realize that there are many variables to consider for even a single photo, but clean ISO 6400 or even 12,800 with in-body SSS makes for a very formidable photographic tool.
Wing Wong
2 years ago |Interesting. This is hardly the “hundreds of thousands” ISO range that was originally hinted at. However, I will take CLEAN/USABLE images in a lower range vs heavily noisy ones in an upper range. Right now, shooting with the A700, between the agorabasta settings and noise reduction in LR3, I’m able to use upper range ISO 3200 and produce usable images in a pinch. If the images coming out of the camera are giving me clean images at ISO6400 or ISO12800, it will truly be amazing.
I’m wondering what the quality of the ISO 50 will be in a final image, and I’m wondering how well the all-cross type AF points will work in the field. I’m definitely itching for a better AF system compared to the A700′s.
Considering that I’ll be getting the vgrip with the body… and I’m in need of replacing the tamron 17-50/2.8 lens, the A77+16-50/2.8/ssm is looking pretty sweet. Albeit pricey… Sept can’t come soon enough. Seriously.

Pete Smith
2 years ago |Saves using ND filters on fast lenses/in bright conditions. Depending on the implementation, ISO 50 is going to give worse IQ than a native ISO 100.
