POLL -- How Long Will the MIRROR live ???

A POLL
How long will the MIRROR continue to live ???
A few hundred thousand clicks, I guess ;)
I think that the Panasonic G1 and the Casio EX-F1 & FH20 offer an
insight to the FUTURE of cameras/photography.
They do, but judging from the abysmal EVF performance of the G1, that particular part of the future is not going to happen anytime soon.
Both do-away with the dreaded (by me at least) "mirror".
The mirror is:

it is noisy,
it causes vibration,
it causes shutter lag/delay,
it adds weight & size to camera,
it requires a "larger" (& heavier) design lens,
it creates a "blackout" during actual exposure,
it is fully "mechanical, thus easily subject to damage if dropped,

it LIMITS to ONLY a (basic) "optical" viewfinder w/only basic
(optical) functionality.

Except for the blackout, (which future evolution could eliminate),
the "MicroAPS" (or future MicroFF) concept eliminates the mirror AND
ALL OF THE NEGATIVES ABOVE.

The micro concept could be virtually silent/noiseless, no vibration,
more rugged if dropped.

In addition to immediate less size/weight from loss of mirror, lenses
ARE CLOSER TO THE SENSOR, thus, can be designed differently,
(smaller-lighter-SHARPER).
Less retrofocs oriented designs would be a blessing for the wide angles.
In addition to no lag/delay,
Huh? If there is anything that really plauges to EVF solutions up to date it is the lag and delay. What you see is what happend a moment ago - a real problem for many applications
it opens the door to the SONY type of
sensor used in the CASIO EX-F1 and FH20 which actually allows
EXPOSURES BEFORE THE PEAK OF ACTION. Those cameras are a virtual TIME
MACHINE ... Those cameras offer a new paradigm in photographic
possibilities.

The DSLR term could be changed to DSL (the mirror creates the
"reflex") ... or my preferred term .... EVIL (Electronic Viewfinder -
Interchangeable Lens).

To be "successful" I agree that the electronic viewfinder needs to be
99% optically equal. Whether that 99% has been achieved may not yet
have been determined -- but I have read great reviews from some
people that are using it.

(Even if it is not "yet" 99%, I am convinced that it can be done. I
have a 6 year-old Minolta A2 with an "almost-acceptable" electronic
viewfinder, and I understand the G1 is 100x better -- with some
military developed technology.)
I had a good look at the panny G1 and found its EVF absolutely horrible. Low contrast, low quality image with painfully slow reactions to changes both in scenery and in lightning.

Nice idea, will soon get much better, but right now not very useful.
BUT ... even when 99% "optical" quality; we cannot forget the 100's
of ADDITIONAL FEATURES THAT CAN THEN BE ADDED.

In other words we will no longer be "limited" to only a basic optical
viewfinder.

An entire book could be written about the additional features that
could eventually be incorporated into electronic-viewfinders. Keep in
mind that you don't even have to have your "eye" to the camera,
remote operation (via monitor) is possible.

Auto exposure could be done differently, with overexposure indication
visible in the viewfinder.

I am convinced that the mirrors end is in sight. But how long before
its final demise?
I fully agree that EVF has a big future, it is an obvious technology for getting rid of a bunch of very complicated high precision mechanical components from cameras. In short if will make cameras much cheaper. And it also has the possibility to add a whole host of useful and intriguing new functionality.

But, as the technology stands right now it lacks performance to replace the mirror in any decent mirror camera.

What I rather see is a development where we get more and more advanced and useful live view implementation in our mirror based cameras, a sort of parallell development where the performance and functionality of EVF will be tried out a s a complement to the optical viewfinder.

I use live view for product shooting and some macro, and would like to use if for remote setups (like in sport) bur for the latter application it is just nowhere near useful yet.

The last bastion for traditional optical viewfinders will most likely be high end professional cameras where users will pay for the diminishing advantage of a very fast optical viewfinder up until the time when EVF finally outperfoms it. But that is still a long way in to the future.

  • Not as clear nor as high res as a real OVF
  • Drains considerably more power
  • Currently requires a focal plane shutter (so much for noiseless)
  • Gets choppy/dropped frames/flickering in low light
  • Contrast AF not as good as phase difference (and this includes the
  • G1, its not even near entry DSLR levels)
  • Zero delay OVF (speed of light), always will be some delay on EVF
  • Go play with a Dynax 9/A900 and beat that for super bright with your EVF ;-)
I say sure, give the consumers their EVF..so they can quit moaning
all the time about these overlays and info graphs they need. And let
us folks who want real viewfinders just get on with the job. Gimmick
driven mania is what I say!

I won't EVER use an EVF based DSLR..you can keep it ;-)
Your obvious hatred for the EVF is well documented around here on the chats.

By your "moaning" about the possible demise of the OVF!

However, you really do need to learn to separate facts from opinion.



Look . . . no focal plane shutter . . . just the sensor!

I just don't understand why it is so hard for you to imagine that other people don't like the same stuff you do!

I personally believe (see, thats me saying this is just my opinion) that we probably will see the end of the optical viewfinder in DSLR's within the next 10-15 years.

And quite possibly the of the DSLR as we know it (again, just my opinion).

Or even sooner . . .

EVF might replace OVF.. but, 43 and m43 wont be around for it. The
tiny 43 sensor means it will never be able to gain any market share
and certainly have no place for anyone who cares about image quality.
Who cares about the supposed advantages of EVF if your sensor blows.

From a practical perspective, one of the major players Nikon or Canon
(possibly Sony) needs to dump their existing lens mounts and go 100%
into EVF and contrast AF (etc) for EVF to take hold. 43 isnt going to
do it.
Tiny compared to the massive APS-C sensor? I don't think so.
Canon/Nikon/Sony sensors never blow? I don't think so. Are
Canon/Sony/Nikon lenses specifically designed for their sensors or
just cobbled together? I think so. How much would the R&D cost be for
these companies to change tack now? Panasonic/Oly have got ahead of
the game. The sensors are getting exponentially better and the lenses
are already there.
Take a good look at your lenses because they won't be much use in
years to come.
( On newer body's anyway ). I'd start saving if I were you.
I think you'll find the G1 is proving very popular and thats just the
start.
Im actually interested in what Oly has in store for their m43 camera. It will be a compact-sized body and not a DSLR wannabe like the G1. That makes more sense i think.

Also, take a look at your 43 lenses.. cause, aside from the 9-18, they wont AF on an m43 body.

Not true, there are several 4/3's lenses that will af on the G1 and all the newer ones almost certainly will. I'm sure a G1 owner will put this one straight. I'd imagine Olympus will be thinking of their existing customer base with their implementation but I guess we will have to wait and see. In any case, af or not, all my lenses are designed for that size sensor and will be perfectly suited in terms of resolution and edge to edge sharpness etc. Canikon glass forget it.

..higher frame rate limits you!

Imagine 60fps, sound quick enough? All well and good, but that also means that the EVF operates at a shuffer speed of no slower than 1/60.

Ambient only I can easily get to 4 stops below that in 'normal' room lighting at ISO1600. So to maintain 1/60 under these conditions we are talking insane ISO's [for the viewfinder display, clearly not the subsequent exposure]; you can imagine what the noise will look like.

Hence as the light drops you either accept lower frame rate on the EVF [not aceptable to me] or so much noise that focus will be very hard to judge (although framing will probably be fine, but i think that there is no doubt that details in the shadows will be very hard to judge)

Panasonic has a compatibility list here:
http://panasonic.jp/support/global/cs/dsc/connect/g1.html

Very few 4/3-lenses will autofocus on the G1, and even those only in Single AF mode (no tracking). And you'll of course need an adaptor making using standard 4/3-lenses a real hassle. And none of the Oly lenses have stabilisation.

Hopefully Olympus and Panasonic will make the compatibility better, at least for new lenses, but they need to increase the number of Micro 4/3 lenses really fast.
 
EVF con list..
[...]
Currently requires a focal plane shutter (so much for noiseless)
DSLR requires moving mirror and focal plane shutter. Mirror slap is the primary source of noise.

Leica M series cameras are quiet and they have a focal plane shutter.

The basic issue (and not only for 43 and m43) is that lenses were designed for phase detect AF; measure an AF point and go to it asap. With contrast AF, its a cycle of AF check and micro-adjustment of focus until that AF point is in focus.

Its also an issue for Oly. Do you design an m43 lens (smaller, less weight, etc) and limit potential sales (it wont fit on a 43 body)..

..or do you design a 43 lens with CDAF (opening the market for 43 and m43), but making it less appealing for m43 bodies since its unnecessarily larger and heavier. Or do you waste R&D resources and design and produce both?
In any case, af or not, all my lenses are
designed for that size sensor and will be perfectly suited in terms

Unless you have the 70-300 or 18-180 which are basically rebadged Sigmas and repurposed APSc/FF lenses.. and they wont contrast AF either.

I see them coexisting for quite a while yet. The simple truth is EVF's just aren't very good or as responsive as an OVF. The laws of physics are darned hard to repeal.

But I don't care enough either way to argue the issue though, so those with strong opinions in any direction should ignore me.

Thanks for the link. Well both my kit lenses will af and I generally only use S-AF mode so that works for me and many others. Why is using an adaptor a hassle?
I use one now for my legacy lenses and its no hassle to me.

Not having IS is not so good but then you will get lower handheld shutter speeds as there is no mirror slap to worry about.
I'm sure the Oly implementation will cover off some of these issues anyway.

The 14-42mm and 40-150mm kit lenses (latest) both work already and they are hardly big and heavy. The G1 is almost the same size as the E-410/20 and people use most of the existing lens line up quite comfortably with those ( Apart from the top end lenses and why would they ). Its a non issue for most people and its not going to be a problem for Olympus unless they produce an ixus sized m43 camera which I highly doubt. You can already use the 9-18mm on the G1. What P&S sized camera gives you that kind of angle and performance?
In any case, af or not, all my lenses are
designed for that size sensor and will be perfectly suited in terms
of resolution and edge to edge sharpness etc. Canikon glass forget it.
Unless you have the 70-300 or 18-180 which are basically rebadged

Two lenses out of how many? the 18-180 is not particularly popular anyway. So we get two rebadged lenses that are not perfectly suited. No big deal either. Having said that they both give decent results on the 4/3's sensor, particularly the 70-300mm so its still perfectly useable on micro 4/3's, just without AF. Oly users are in a far better position to take advantage of m43 than any other brand for obvious reasons, that is undeniable.

this doesnt appear to have been an issue for manufacturers who field lenses for APSC and FF, and where lens transfers across APSC/FF create less desirable optical circumstances. Nonetheless wouldnt say that they waste resources designing lenses for 2 formats.

in the case of mFT this is an adaption of utility, even if they wont AF as a purpose built CDAF lens would (which they wont), optically on the lenses are suited to the same image circle, whatever the AF compromise, it seems there is no optical compromise.

prior to this you were erroneously suggesting non of the 4/3rds lenses would AF on mFT, and even as recent as some hours ago you still believed that only the 9-18 would CDAF

a number of lenses have had firmware fixes to CDAF on mFT and be advised, not all lenses have had firmware rolled out. Olympus are unique in the use of updateable firmware for lenses
In any case, af or not, all my lenses are
designed for that size sensor and will be perfectly suited in terms
of resolution and edge to edge sharpness etc. Canikon glass forget it.
Unless you have the 70-300 or 18-180 which are basically rebadged
Sigmas and repurposed APSc/FF lenses.. and they wont contrast AF
either.
which is the gamble people take with 3rd party lenses, that of lower prices/compromised quality, nothing really different there either

But if you truly believe what you say, it does highlight the case, that IF an APSC variant appears, EXACTLY the same lens issues present. Except, they probably wont be able to update the firmware. And ultimately neither Canon or Nikon will have an EVIL body for just this reason, as they would then be servicing 3 lens suites. Which makes a Canon or Nikon EVF camera a fixed lens camera, that might be ok, but it is less versatile.

Good for you. It would be for me. IMO the big advantage with Micro 4/3 is compact size and light weight. Using an adaptor increase the number of parts and volume I need to carry. Also if I switch between Micro 4/3 and standard 4/3 lenses I either have to mount and unmount the adaptor for each switch, or (maybe better) have one adaptor for each standard 4/3 lens.

Btw, I think Micro 4/3 is a really great idea and really liked the G1. I might even buy one when they get the 14-140mm out.
