Will Alpha Preview??

[Dat Ei]

Hey Bernie,

It really wouldn't, AS doesn't work that way. It's only designed
to activate when the shutter is activated.

sorry, but that is only true for the D7D and D5D. Cams with EVF and AS, like Dimage A1, A2 and A200, can be cinfigured that way, that the preview is stabilized while focussing. But permanent AS:

• drains the batteries
• heats up the ccd/cmos (more noise)
• could be critical for a chip with APS-C size

I know it would have technical difficulties, of course, but actually it works so only when shooting because of it is now unuseless when framing with no live-preview. Things can change.

Who talks about EVF ?

I meant lift up the mirror and use main sensor with on-screen preview. Sony, as far as you havent a several-megapixel-really-real-time-refreshed EVF, please keep it Optical as it is now!

I think this reply is pathetic. You may not want any progress in
DSLRs but others do. To try to defend the deficiencies in
technology is to bury your head in sand - they will come. The lack
of preview is not a virtue - it is a deficiency due to current
sensor design.

Just imagine photographers like Ansel Adams trying to compose their
full plate cameras using a wire loop instead of a large ground
glass viewing screen, howbeit upside down - do you think that their
photos would have been better or worse ?

I would like a live histogram & would even tolerate an EVF if it
were of high enough quality to enable me to judge exposure in
real-time. The clear optical viewfinder is nice to look at &
enables fine detail in composition to be assessed but you have to
check that all is well by looking at the LCD post shot to be sure
that you got what you wanted. Many shots have to be re-taken to
fine tune exposure etc.

DSLRs have been developed from old fashioned SLR technology & have
not been changed too much to ensure the compatibility of older
lenses & accessories etc. If digital cameras had been developed
from the ground up as totally new projects they would already look
a lot different & I confidently predict that Pro & semi pro
cameras in the future will only bear a passing resemblance to
todays models.

Also, read why lenses suffer from having a mirror to handle and why the distance between the sensor and optics are an issue.

What really surprises me is that it seems to be either/or, not 'also'.

• Why shouldn't a cameramaker be able hold both a 'mirror' line-up

and a EVF line of cameras and let the market decide.

Got tired of saying that, but you can have an OVF camera that previews.

 

[assafb]

OVF cannot be stabilized with AS naturally.

LCD preview can be stabilized on the LCD, but it won't be significant, as the LCD is too rough on detail and too late in response to movement to allow you to see subtle vibrations anyway.

So I don't think AS will interact with preview. But that's just my take on it.

 

[Dennis]

I just posted one idea as to how to do that before in this thread,
but there are many solutions that let you keep the mirror/OVF
format.

Live preview for the sake of live preview doesn't interest me. Live preview that exploits a large, bright, high-res, EVF that lets me preview, focus precisely and see depth of field in low light BETTER than an OVF would be welcome. And ditching the mirror would be a plus.

I don't really see the point of a split system; I'd rather dual lines of cameras, though that might be too much to ask of a manufacturer. I could certainly see someone like Sony doing EVF at entry level while keeping OVF at the higher end ... maybe throw in a MLU-based live preview on the LCD for those who find it beneficial. And then work toward a truly superior EVF that's visible in any light, but better than an OVF in low light.

So you can try to soothe the anti-live-preview crowd with compromises, but they're little more than compromises. Instead, build a true live-preview, mirrorless camera with an awesome EVF, sell it to whoever recognizes the benefits and let the OVF-or-die crowd buy cameras with OVFs. Why try to be everything to all people ?

Yes, you are right !
Vibrations than can be corrected by AS will surely not be appreciated on screen.

On my A2, it can be set either way. I normally have it set to exposure only. I tried it the other way briefly and couldn't see any difference. However, I remember the canon S2 review here mentioned this. I just looked it up and it says that it made framing easier to have IS premanantly enabled, FWIW... The EVF in the A2 is somewhat less pitiful than the one in the S2. I also remember reading (in a full-frame related thread I seem to recall) comments that AS actually shifts the sensor a lot more than you might expect, maybe in the region of a centimetre, at maximum - I'm not sure.

p.s. What an out of hand thread. It seems like some people really need to learn to take a step back and discuss things rationally...

 

[Lars Holm]

...so I take it you are an engineer or similar with extensive knowledge on the subject?

No? Then don't expect people to take your fantasies as facts.

 

[pinnacle]

A 4 ass monkey would be evolution in motion, doesn't mean it's a
good step or will be successful.

Why can't you accept that some things are very nice as they are, or
that your "improvements" may not be improvements.

A lot of people could care less about adding new fangled things and
other toys to stuff. Some people value function and quality design
first.

If you haven't used an "articulated" LCD, you may not be able to appreciate the value of its' "Function", as you devalued the E-330 feature.

People keep whining for their Life Preview, Tilt screen,
Mirrorless, EVF, movie mode camera. Well, Olympus gave you the
E330, it's the first and only camera on that path

Maybe the "first" (only available for a few months)...but I promise you, not "only" as users find out about the new usefulness of this added to existing SLR design, other manufacturers will add it to their offerings.

, so why not go
and support them and get them to keep pushing it forward instead of
trying to convince every manufacture they need to up and change the
evolutionary path they are on.

Users "whined" about image stabilization too...should Konica/Minolta have thought, Gee, that's not an "SLR"..."that belongs on point and shoot" cameras"

A SLR is a SLR, if it's not what you want, don't go yelling in SLR
forums for something different. You clearly don't want a SLR.

Maybe he wants an SLR with more features...

Is there a design criteria list from which SLR manufacturers dare not deviate? I thought "SLR" meant Single Lens Reflex". Beyond that, isn't it ok to add just about anything users find a interst in?

What if Pentax (the first auto focusing SLR) thought "Oh no, we can't add autofocus to an SLR...that is too radical...

Sony will do a wonderful job, innovating in the DSLR market. Try and embrace the spirit of useful new features and go easier on your forum members.

Congratulations to Sony and Konica/Minolta users on the new Alpha announcement. Looks like the start of something great!

Hi,

Yes I am an engineer with quite a few years of real-time devices experience. Cameras are just one more when you take the lens out.

Didn't like your tone.

With a current DSLR you can check your shot and histogram a fraction of a second after the shot and retake it with different settings if you don't like it!

In many circumstances a fraction of a second is quite a lot.

Many are saying the sensor is similar to that in D200, so that means no Live Preview. Too bad though.

If it's indeed the case, I'll get a Rebel XT for a cheap

Will it have a version of preview.

[ab012_KM7D]

Why not 5d then?

excellent 2.8 (eg KM 28-75 2.8) lens +AS +good high ISO (RAW, not jpg)

If it's indeed the case, I'll get a Rebel XT for a cheap
(body) and start building my lens collection. A couple of cheap
F2.8 and F4 lenses and the high ISO performance would be able to
compensate for the lack of AS though.

Will it have a version of preview.

Seems kind of silly... I don't believe the XT has live preview either, nor is Canon likely to incorporate live preview in a camera anytime sooner than Sony. Whatever. Enjoy it.

[Minh Ta]

But is it true that Canon's sensor is better than the one in 5D (in RAW mode also)? I do shoot RAW most of the time. I believe that the performance of the XT (focusing speed, buffer etc) is somewhat better than 5D although I could be wrong. Last, but no the least, many of my friends have Canon's so I could swap lenses with them if you get the XT.

Bernie, my point is that if Sony's offer doesn't come with Live Preview then I have no reason to get one of the best (and cheapest) DSLR in the market that doesn't have Live Preview either. Why pay for > $1000 when you can get almost the same with only
