foggy evf,lcd,ovf compared partII

There were some nice remarks on my little game with the xacti lately:

http://forums.dpreview.com/forums/read.asp?forum=1033&message=23291231

I did a little experiment while drinking a coffee.......

I have redone this "test" now to answers some questions in the thread above.

Again-- This is a "test" that could be done better by professional testers with their perfect equipment.

Restrictions:

  • There are reflections on the lower parts of the lcd (also in real life - even more!!), but I have tried to reduce them.

  • The FZ5 has a screen protection - it has to, otherwise many scratches would make the picture invisible.

  • Our impression looking through the evf is different (but there are not more pixels anyway)

So here we go - the second game with the xacti E6:
(this tiny camera shoots anything without toys like achromats)

FZ5 evf

FZ5 lcd

Nikon F301 SLR 50mm prime lens ovf

The scenery taken with the xacti

And last but not least:
Xacti E6 3' lcd

I don't dare to comment this - take your own conclusions and read the thread above.

Panasonic may have improved the finders lateron, but they sold a camera with such finders before ;-).

Cheers

Re: foggy evf,lcd,ovf compared partII

Hi Sven, sorry to have caused you more work, but
I appreciate it. It looks about as I had expected. I
think though that the SLR got a longer exposure than
"real life"? (Some bright areas are brighter in the SLR
picture.) So in reality, the SLR finder would look a bit dimmer
in comparison.

Speaking of dimmer, the FZ5 would probably look better if the
brightness was raised a notch, for this exposure.

But for resolution it's pretty representative.

As did most everyone at the time, even in cameras costing a good deal
more.

Maybe the price of higher res screens is what's changed the most
since then. The 230k of the Sanyo makes a difference.

Again, thanks for the demonstration.

Re: foggy evf,lcd,ovf compared partII

thanks Erik,

my main point was a test of resolution...
It is is not so easy to take a good picture through the viewfinders.
There is chromatic aberration and lots of artefacts..

I have tried to reduce the "pixelation" a bit:

FZ5 EVF

FZ5 LCD

Xacti LCD

Re: foggy evf,lcd,ovf compared partII

addition.......

This is the list of the technical specs.
Starting with the FZ8 and FZ50 there is a significant increase in resolution.
Modern cameras have the resolution of the xacti camera.
This is still far away from the SLRs viewfinders, but much better than my FZ5.

sanyo xacti e6
lcd 3 ' 230.000 pixel

FZ5
lcd 1.8' 130.000 pixel
evf ??' 114.000 pixel
FZ7
lcd 2.5' 114.000 pixel
evf 0.33' 114.000 pixel
FZ8
lcd 2.5' 207.000 pixel
evf 0.44' 188.000 pixel

FZ20
lcd 2.0' 130.000 pixel
evf 114.000 pixel
FZ30
lcd 0.44' 230.000 pixel
evf 2.0' 230.000 pixel
FZ50
lcd 0.44' 230.000 pixel
evf 2.0' 207.000 pixel

zoom out

Yes, though the large size brings the pixelation very much
"in your face". I feel that clicking on "Zoom out" once, gives a
closer representation of how the eye sees the EVF & LCD.

Doing that, the remaining problem is that shadows and midtones
look dark (compared to the xacti LCD). I'm unsure if this is due to
this particular scene/exposure or to your xacti, when shooting the
VF, having less DR than our eyes. I feel the EVF normally gives a
good preview of the exposure (though direct sunlight can be
disturbing).

Re: foggy evf,lcd,ovf compared partII

Sven, I am impressed by your visual comparison of EVF and LCD resolution. I own FZ5. I have never thought before the viewer has so bad quality. But, you are right. I think our eye compensates and complements the missing information. Now I can explain why I prefer to look at the object without EVF first and to get the right frame I switch to EVF.

Thanks for enlightening on this subject.

Regards,
Mustafa

Thanks - you are right, this is better!

I have to leave some work for others.
My job with the resolution is done....

In real life it is a bit better, but not concerning the resolution....

I prefer the EVF to avoid those many reflections on the lcd screen.
The resolution is equivalent anyway...

less misleading remark

Just to stay fair, here is a final remark.

I have resized the picture taken with the xacti to the scale of the finders and resized it to 1000 x 750.
--For comparison--!!

This is close to the theoratical resolution of an ideal screen at that resolution. The truth will be somewhere between my shots above and these pictures.

Here we go:

1. downsized to 114000 pixels and back to 1000*750

2. downsized to 230000 pixels and back to 1000*750
