Sony A55 transparent mirror removed and analyzed!
Image credit: TheSyberSite analyzed
TheSyberSite (Click here) investigated the bugs and limitations of the Sony A55. And he gave a particular attention to the translucent mirror construction He actually removed the A55′s mirror!). The mirror is made by flexible plastic (See the picture on top). Also without the mirror you can use the A55 to take picture (of course autofocusing will not work!). It would have been nice to see if there is some kind of improvement in the image quality. That’s why I contacted the author of the test. He said he will post such a comparison soon.
Thanks Ray!

2 years ago |good question.
Where exactly is the infrared filter located?

2 years ago |It would allow for more light on the sensor, loosing autofocus during the exposure.
Also allow for IR if the sensor filter was removed. (I’m assuming (and could be wrong) the beamsplitter does not transmit IR so well.)

0.18 clearly shows mirror outside of lens mount.

It is possible you posted it several months ago already.

2 years ago |Old news…many sites have tested this..for instance SLRclub tested this almost a year ago…without the mirror you get pictures that are a little bit brighter(0,3ev) and sharper.

2 years ago |Thanks for the link! Completely missed that!

2 years ago |Are they really sharper? Or is it just because the no mirror samples are brighter? When I look at the comparisons between the A580 and A55, I can’t see much difference in terms of sharpness. Although I am currently on a really crappy screen…

In did, it’s an old stuff.

2 years ago |Andrea this is a question to You….not actually related to this subject but still……can You ask Your sources does a77 suffer from SEVER jello effect like a55 (and a33) or is that issue solved? (I know it’s due CMOS technology….)
admin
2 years ago |I have been told Sony worked hard to minimize that. But we have to wait until the camera has the final firmware before to make a final judgement. But it looks good, actually very good…

2 years ago |What doesn’t suffer from this? CCD?
I never noticed the jello effects. I just youtube-d it after you posted o.o
feedmatekill
2 years ago |oh, the jello effect is really severe on a55, for example see here http://www.youtube.com/watch?v=iYLLLrTwnbU&feature=related most of my photos are wildlife and kinology related jobs….I would like to have an usable video option….but that would mean that I need real fast and accurate AF tracking (which I have never dreamed to get from DSLR or SLT for that matter) and elimination of that horrible jello effect that looks terrible….
I have been told that d7000 is far more better in that regard so it’s possible
feedmatekill
2 years ago |Yes CCD are immune to jello effect
ahhh-lpha100
2 years ago |Hope the mirror in the 77 is not removable. Would prevent dust reaching the sensor… (if properly sealed at the edges).
