D600 Full Frame announced! (not official yet)

[fmeeran]

I mean A Mode (full-time live view) with PDAF, only in B Mode (macro live view) the mirror flips up.

Lots of Sony Alpha DSLR bodies had an improved implementaion of it. The AF is as fast as through the viewfinder, exactly the same PDAF CMOS sensor is doing the job in both modes.

Sony DSLT have translucent mirror to split the light to the PDAF module during liveview. As for nikon, except the one camera adaptors, the other cameras don't have the translucent mirror, my guess is they have to flip mirror to PDAF.
I'm not very well read on this. Please correct me if I'm wrong.

Thanks for the link. As Discovery channel says I have learnt something new today.

So you'll still need the primary mirror to be translucent or you'll need a secondary AF sensor if you don't want to keep flapping the mirror (either in liveview or vf).
As an optics person, I personally don't like loosing light to translucent mirrors. Would rather settle for CDAF in liveview.

The the primary mirror is always translucent in every D/SLR with AF ever build. Anyway, Olympus' and Sony's system doesn't need a seconday AF sensor. If you have a 2nd CCD/CMOS you don't have anything in your light path when taking the photo.

Well I already mentioned it before that for LV for some Sony DSLRs, they have a LV vam inside the viewfinder box.

I would think there will be some issues implementing this solution for Video enabled DSLRs... is this same feature available to Sony DSLRs with video?

Didn't know that either. Back to the drawing board for me.
What I meant to say is that when the sensor is imaging, I would prefer there be nothing in the beam path to it.

Thanks. I've always assumed the AF sensor is sited where the AE sensor is.

I wasn't questioning that.

for most DSLRs, the primary mirror is only translucent in part of the mirror... not the whole mirror. so light passes through to the secondary mirror that reflects that light to the AF sensor.

Only in two models, A560 and A580, but not during video.

 

[kane-rulez]

and now its a Sony thread Though the information exchanged was quite insightful

 

[zcw123]

i heard a few working photogs saying that they were invited to review the D600 by nikon sg . don know if this is true...

I hope so and I hope the other brands will release a bunch of cheap full-frame bodies as well.

 

[xtemujin]

As a Nikon user, even when new camera models are announced and released, it gets very frustrating as the stocks are not readily available.

The nikon 1 cameras have sensor based pdaf. And they seems to have excellent af from reviews?

 

[lenslust]

This "rumoured D600 FX-format DSLR" is looking real as time passes...

AFS 50mm f1.8G, AFS 28mm f1.8G & now AFS 24-85mm f3.5-4.5G VR; besides updating all their lenses, surely these 3 lenses will do little to tickle owners of the D4/D800Es ... :think:

I would be more interested in having a 120-300 f/2.8 or maybe a 24-104 f/2.8.

lol, yes but not with F-mount lenses.

 

[spree86]

A 24-104 f2.8 would be huge, just look at the size of a 24-70. Anyway, there's already a 24-120 f4

Yeah, not expecting it to be small in size, but the range would seriously be good. Or the 17-80 f/2.8 in FX.

Of course, I'm just being greedy.

The 3rd party tamron lens can be done on 28-105mm f2.8 and very hard to find now.

Surely the range will be good..and yes not wont be small...too big..nobody will like/want..or maybe you might be ranting "too big.." as well..dont be surprise. Oh wait. It will be heavy as well..
So if they were to make it small and light. How much do you think it will be priced? And how many people will buy. Come on..be realistic..it will happen..maybe in the future but that should take awhile more or much more.
