(SR5) More small info about the A55 and A33!
1) 15 point AF sensors, 3 cross type, 1200 segment metering
2) The A55 and A33 do have a 100-12800 ISO range. And it can go up to 25.600 ISO combined with the Multi Frame NR function! In Auto setting the iso range goes from 100 to1600 ISO.
3) Sony redesigned the shutter unit which now is more compact.
4) Compared to the Sony A550 the body is almost 2cm less height! This is possible due the more simple Translucent construction (and the new EVF).
5) The A33 weights 430gramm and the A55 440gramm
REMINDER: Tomorrow Sony will announce the cameras….follow us! We will give you every update, every news, every preview we can find!

Mistype?

this might be available for only jpeg files, i can’t imagine it would be available for raw files. So the ISO performance might only be marginally better than the nex 3/5

3 years ago |I am really hoping that the IQ from this camera can be as good,if not better than the Nikon D90. I love the D90 but the smaller form factor and the great images I am getting from the NEX5 is making me want to change over to Sony altogether.
This looks impressive even if the ISO performance is just a tad better than the NEX5, I would be getting video/still IQ plus the form factors in a relatively small size SLR.
Lets see what the reviews have to say.

Myst: in raw, u can over expose the EV by 5 stop, hence its erm,… 4,096,00iso?
(but if i am wrong, maybe the software can only do +3eV, the its still a 102,400iso.

3 years ago |Usually in raw converters (LR3, DxO) is possible to correct exposure for +/-4 stops. I recently tried it for A900 and found that even one stop underexposure at ISO6400 (12800) is awful and unusable.

So… that double cross sensor… is the cross in middle. Hmm… makes me really wondering how good the AF is, especially with AF-C while tracking objects while in 10FPS mode. And how good the AF is in poor light conditions.

3 years ago |The location of the extra 2 cross AF sensors, are completely stupid and useless.
They should have placed them on the left and right side!
Sky_walker
3 years ago |O_O oh… right… they are on top and bottom. LOL!
Who came up with this? What’s the purpose of such arrangement? duh…. I hope they gonna sell grips for A55/33 – if so than Sony invented first dedicated camera for vertical shooting!
Myst
3 years ago |you can over expose, but i was hoping for better sensor performance altogether, cause if the max iso increases all other lower iso values will have better noise control, i got a bit excited about the new high ISO of 25.600 that meant they made the sensor even better cause so far nikon d90 and d5000 sensors are better than any Sony APSC sensor(not by much but they are), the only reason i am sticking to Sony is the SSS and some of the lenses
Stupig
3 years ago |This 15-point AF arrangement is pretty disappointing. Let’s hope it work well though – because if the 1/3 stop light loss to sensor is true, there may be a stop less light going to the AF sensors compared with current SLRs.
sgts
3 years ago |seconding the placement of the focus points – there should be two on extreme right and left – instead you’ll get some dumb advice in the manual to focus using centre point and then move camera right or left : (
are sony incapable of developing proper focus points ?
dk
3 years ago |What happens to that triple-crossed center sensor that was rumored a few days ago?
Stupig
3 years ago |Maybe then meant “three” crossed sensors instead of “triple”.
Edgars
3 years ago |I also preferred cross-type sensors in left and right sides, but anyway it is nice if they are f5.6 (with light loss f5?) sensitive.
Jumping Monkey
3 years ago |crosstype line up??
why’s that?
Sky_walker
3 years ago |So that you could catch focus on planes flying above the subject.
Jumping Monkey
3 years ago |. . . i think it’d be more useful if they’re in side position.
it good for tracking subject in many sport. Runing Racing Football and basketball in vertical.
PMac
3 years ago |Obviously we are talking about rumors that may not be (completely) true but a lot of people are focusing on the obvious and missing the slightly less plain.
An earlier rumor suggested that Sony had developed a color/contrast tracking system akin to the Nikon algorithm. I must admit I dismissed the idea as that would require a totally revised metering system. Now this rumor emerges saying that Sony has moved from a 40 something cell meter to a 1200 cell system and I’m wondering about that earlier rumor again.
Ultimately 3 crosses, 5 crosses or 51 crosses means little without the smarts to tie them together – it appears Sony may (and I stress May) have figured this out.
Neonsquare
3 years ago |The 1200 cell metering system is nothing new – every Sony alpha with Quick-AF-Liveview has it. Since the A55 and A33 are EVF cameras with “always on” liveview – they just use the known 1200 cell metering in EVF mode too.
PMac
3 years ago |Neonsquare,
I cant find a single authoriative reference on the net saying the actual metering in the quick view cameras is anything other than the 40 segment honeycomb that minolta had back in the day.
Can you point me at one?
PMac
3 years ago |Scratch that – found a reference.
Curiously this is little reported on – has anyone noticed any difference in metering performance between the 40 and 1200 cell systems?
