Funny, the live view problem doesn't happen at all in my entry level DSLR.   

Sure? The mirror flip will cause the black-out, I thought it's common? I remember I tested before D3000 and D5000, they do have these issues, so does 550D. It should be the same as it's the way DSLR works.

Andy214, Agito666, mind if I give opinions and facts on Sony? The SLT is more on high speed AF in video, more on that later. Normal Sony live view since its 1st LV enabled DSLR (A300) is already using the quicker phase detect AF as opposed to canon and nikon's contrast detect AF in live view, thats why you will feel that LV in your camera is slower than when using OVF. Sony uses a separate secondary sensor to feed the live image to the LCD while maintaining the light path to the PDAF sensor - as opposed to using the main sensor in your unit.

As for dSLT, because there is no mirror in the path (only a transparent piece of glass that splits 30% of light to the PDAF sensor) the video now enjoys full time PDAF as well making it blistering quick. The downside now is that it is TOO quick, making any abrupt shift of focal plane looks very sudden. Good for quick action movements and fast paced tracking. But looks totally weird in slow moving scenes. The other 'concerned' downside is that the 30% loss of light will be equivalent to about 1/3 stop, which I think is still very reasonable.

the sony a300 a350 a550 a580 will still black out when the mirror flip to take picture. Just that the LV speed is faster thou

Tats why u need wandeeassmakthree 

19cross af all over screen.

Or wandeemakfor 39 

okay, boss
how about when you put your DSLR on floor? low until cant lying on floor that one.... XD
then had to rely on Live view right? or when not enough tall, you had to rely on Live view also right? 
that's why i ask that XDDD
OT: what the heck with the nymph, i wan azunyan. 

1DMKIII is plagued with AF problems. It seems 1DMKIV also inherits the some of 1DMKIII's AF problems. 

Anyway, it's all nice having 39 crossed type AF points but many fail to read the fine prints. The 1DMKIV will only have 39 high precision cross type AF (horizontal and vertical) points when a lens with a max aperture of f/2.8 or more is used or when combined with an extender. The cross type sensors vertical line sensitivity is approx two times more than the horizontal line sensitivity.

However, when using f/4 lens itself like the 600mm f/4 or by using a f/2.8 lens with a 1.4x extender, then only the centre AF point is usable as a cross type with the other 44 will only remain as non-crossed type (horizontal sensitive) only.

Using a f/5.6 lens or by using a f/4 lens with a 1.4x extender, all the AF points are horizontal sensitive and using a f/8 lens, only the centre AF can be used as a non-crossed AF while other are unusable.
I mentioned before that I don't use Live View but there were actually times when I remember that I did use it.  Not to replace the viewfinder to shoot but to use it to check WB. Switch on Live View and adjust / tweak WB on the fly and watch it on the LCD screen before you take a shot.

currently thinking to get a potrait lens.

85mm or 50mm? i can afford a f1.4. means no doubt go for f1.4 instead of f1.8 right?

been reading reviews about these, 85mm and 50mm f1.4, the only difference is the distance to shot?

need sifus advise, thx! 

Yesterday work... what you see? 

Focusing is horrible on that body unfortunately, which is why the D3 triumph over it with the stellar AF performance under low light for sports.[

custom love bokeh     

I see lots of blur at the upper part of the image... and I wouldn't have included that tree trunk, too distracting.

Yesterday work... what you see? 

  how come in so many intl sports even still so many canon wan ?

I feel dizzy >_<

errrrr..... you mean.......??????  

i am on DX. so 50mm means around 80mm, while 85mm is 136mm right?

for half body portrait, 50mm lens should be better right?

guess i'll just search for a 50mm f1.4 for a try. thx
