Here is what I want to avoid, it is really underexposed, but still no texture in the sun. With Hassy and a provia ou ekta, I wouldn't have such problem.

Is that so? Do you have an example?

Cheers,
Bart

Foreground seems rather underexposed ...

So you should be horrified by the price of a painting of rodko

Regarding the underexposed background of course yes. But same exposition on DSLR, same sky color, only white in the sun and lots of bull...t around it.

Esox, you may get yellow sun when it's coming next to the horizon because of the atmosphere which blocks shorter wavelengths. We know that.
It's not a matter of DSLR vs MF.

Nice shot, but I find the ghost image over the sun itself to be quite annoying.

Thanks mac_paolo. This ghost... well you are right, the thing is that I have a kind of religion : do the photoshop to the point of what's on the slide. You are right on the fact that no ghost would make the picture more simple and "direct". But I find interesting the presence of this ghost, it's also shows the strength of the sun. In fact I'm in the middle of two religions : the one that put the impact and the reading of the picture in itself number 1 and the one who put in number 1 the subjects on the pictures. As we say in french : between the two, my heart swings... Sorry for the awful translation. I'm opened for a better one or maybe the english equivalent...

BTW, I always shoot the same picture with DSLR to double check the exposure with same parameters. The DSLR version has a white sun...

I guess it's a question of getting the right exposure for the sun, it doesn't have to be burnt out, regardless of the camera you use...

Hi,

Digital works fine until one of the channels is clipped. So you need to keep exposure low enough to avoid clipping. All digital stuff works that way.

Best regards
Erik

Hi,

With digital you can always get moiré. That essentially means that the lens outresolves the sensor. Most DSLRs have an OLP (Optical Low Pass) filter that reduces aliasing by softening the image. MF and some 135 cameras don't have (Leica M9 and Nikon D800E). Sigmas have no OLP and a Foevon sensor, producing aliases but no color moiré.

Would be thankful if you could point out the moiré in my picture because I cannot find it.

Best regards
Erik

Because it seems there is moiré on the tablecloth...   Wink

I can see some red/magenta ghosts in the texture on the tablecloth behind the last cup. It doesn't seem to be the color of this tablecloth.

Hi,

I don't think it is moiré as moiré looks very different from that. The shot is made in my living room. The "table cloth" is a dust cover for a slide projector I have. The table is glass. What I guess you see (and me too) are some weak reflections of a few colored books standing outside the picture either in the glass  below the table cloth or in the lens itself.

Best regards
Erik

No,

I guess the color you see are reflection of items outside the image.

Moiré arises when a lens has high MTF at sensor resolution, in practice low to medium apertures. It is also a sharp pattern. The reason I'm pretty sure it is not moiré are because it doesn't look like moiré and it's not in a situation I think it would arise.

The MF cameras you consider will be much more prone to moiré than my Sony Alpha 99 as they don't have OLP filter.

Best regards
Erik
