Sony A33

[albertri]

Bought a33 at Cathay this afternoon. So far so good.

How much Cathay charges you bro? paid cash or cc?

I'm waiting for A55 very tempted

Cathay should be charging the same price cash or credit if I am not wrong

The DSLT technology certainly looks exciting but can any bro enlighten me on what is the difference between the Sony DSLTs and the micro 4/3 systems? I'm not referring to the sensors and mounts.

When I compare both systems, they are all just EVIL systems. What is the advantage of having an translucent mirror in DSLTs? Micro 4/3s (or even the NEX) don't have such a mirror and they seem to work in the same fashion?

Anyone?

*Confused*

Actually slt has a mirror it's just that the mirror in slt are translucent so it doesn't need to swing up when we press the shuttle to allow light to hit the sensors.

M4/3 and nex doesn't have any mirrors at all. The light goes direct to the sensor and out put through eve or the LCD live view . As such the flange distance between the lens and sensor in m4/3 and nex are reduced. In slt the distance remains the same so the normal alpha dslr lens can be used.

One of the big advantage dslr over mirror less cams has is it's autofocus speed as it uses phase detection which is much faster than contrast detection used in cameras that use LCD live view for composition.

So hope that explains the difference rudimentarily

The main advantage of SLT over Nex/M4/3 is enable the use of phase detect af which is faster than contrast detect af.

Hopefully all mirrorless format starts to employ phase detect af sensors built into the main sensor (like what fuji did with f300exr and also canon seems to have patent some design which uses this concept in their upcoming evils), then that will be the time that SLT may not be as useful as of now.

Hi, IMHO, no intention to trol, just impulse.

Can I say the non swinging mirror is a contributing factor to the higher FPS?

Can I say the non swinging mirror is a contributing factor to the higher FPS?

And also the constant PDAF which is in focus all the time since without swinging mirror to distrupt it as in normal DSLR.

Hi, I think so. But to increase 6fps to 10 fps, u need to use the "Continous Advance Priority
AE" which gives a continous flow of light from the lens to the image sensor, locking the aperture
all the time to produce 10fps as the imaging sensor has 70% light.

I think the lesser light of 70% has nothing to do with aperture locking for 10fps.

It locks the aperture so as to reduce the time needed to stop down the lens to the required aperture setting...so less time needed as the sensor can fire away continuously while PDAF is always in focus.

So it becomes the only bottleneck is shutter and how fast the processor can capture and process the images.

and your cam buffer memory also and how fast your memory card accept data from the cam. All these factors affects unless you taking in short burst of photos.

Hi, Agree. No stopping down so as to allow the sensor to work continously without interruption to produce 10fps.

SLT also allows the the use of existing A mount lens.... that's a VERY big plus.

Was reading about the SLT Sony says 70% of the lght goes to the Sensor and 30% of the light goes to the OVF... was thinking how would this affect the image? compare to a normal DSLR?

This is almost the same principle as ND filter....

Would be nice if someone who owns the older Alpha and newer A33/A55 to shoot the same subject same setting same lighting and same lens and f-stop.... see if there's a difference in terms of brighness and saturation.

Hi, Agree. No stopping down so as to allow the sensor to work continously without interruption to produce 10fps.

In order to achieve full 10fps i think you need a fast memory card e.g. class 6 or higher SD-card. I am using a different brand of cam rated as 5fps you can achive 5 fps while the buffer memory is not full once it fills up and the memory card cant catch up it start to slow down

Already discussed to death... It's only 0.5 stops, not significant.

Hi, that is a good link to read besides dpreview on SLT A33/55

cool tks sorry was new to Sony SLT hmmm .5 stop not that bad for non pro i think it wont matter much
