Indeed. I also don't recall seeing the 3D effect in the viewfinder, though recent shoot with Pentax MX was, well, let us say it was very refreshing to my eyes. However sometimes, more seldom than I'd like, this effect is present in my photographs.

Interesting thoughts Boris.
But I never saw that effect with a 50mm on 'FF' or 30-35mm on APS-C.
Viewfinder/lens may very well be the 'culprit'. Or lack of 31/43 Limited :) :)
I really don't think this is a DOF issue. After all, my FA50/1.4 has
less [email protected] than the 80/2.8 on 6x6.

The problem is the following, my (very basic) enlarger is 24x36 only.
No 6x6 prints at home. No way to check until I can afford a proper
enlarger (which ideally would do up to 4"x5") which won't be tomorrow
or the day after :(

I know this has been debated quite much and that it is somewhat weird
to talk about 3D in a photograph but...
man, my C330 does throw at me exactly that in its waist level finder
and 80mm/2.8 lens.

Is that the lens? The finder? Medium format DOF ?
I'm surprised and...  impressed !


I think that 3D look has to do with specifics of how we psychologically
perceive images. My understanding is that on 6x6 camera 80 mm lens has
approximately the same angle of view as 50 mm lens on 35 mm camera - normal.
It also occurs to me that may be MF viewfinders are just right in a sense of
how large/small they are. I remember distinctly the same feeling of surprise
looking through Jostein's Pentax 645 camera - the striking sense of
presence, as if being inside the scene. Another thing to consider is
tonality and OOF. If there is a smooth transition between dark and light and
sharp and not sharp, it probably looks more real. It is because the eye
would adjust itself according to the specific small area in the scene at
which it is staring and it would basically feel "normal". Smaller cameras
and hence wider lenses (for purpose of similar angle of view) would have
this "everything is sharp" kind of perception, although its degree would
differ from camera to camera and from lens to lens.

I would be curious to know if the 3D feel is retained in the prints that you
evidently make, Thibs.

Hope I make minimal sense.

Boris
