No it was directed at Trendlands story about a guy from Cologne right above my post.
Righty right Helge - I got it in mind but I don't remember the name oft that Cologne stationed photographer. He was specialized with 4x5 inch bw since many years and "tryed" a comparison with a digital Nikon (in bw modus/bw post processed digital source)!
And nothing less than Ilfords Delta100 in different formats he sent into that competition!
From my point the Delta 100 (with superior developer) is one of the best (and highest resolutest)
films one can get today beside special microfilms.
In 35mm Delta100 is showing extraordinary details with perceptol and box speed ISO 25 - 50!
Of course one should use a very good lens at the optimal aperature (with trypot). This Cologne
guy did all oft it - obviously in a very precise manner (he knows his job).
With 6x7 format Delta100 is R E A L excellent (just from my point) !
But this guy came from his test run concerning resolution to following conclusion :
35mm Delta 100 has miserable resolution in direct comparison to the 36Mp Nikon D800.
6x7 with Delta 100 is quite better but the 6x7 format isn't able to show the finest details the
D800 easily provides.
First with 4x5 inch the result of film was superior in comparison to digital!
But it wasn't very much better. Friends I wasn't able to find this article again

!
I am sure I had this article saved from the net. But it is much more complicate to me to remember
where I stored that saved original article than starting to reserche it from the net again

......
I found the blog of that "Cologne guy" there he discribed his NikonD800 vs 4x5 inch comparison
in a short form.
The original "test" was much longer (3 - 4 pages ) if I would only remember from where he publisher?
It wasn't Petapixel - it was more in direction of a photo magazine?
Never mind the original test was in addition with a midt format Hassi 80Mp.
And from his resume he found out that 4x5 Delta is nearly the same like 35mm digital.
But the Hassi in midt format was real better than 4x5 !
?????....

....????
So he decided that 4x5 inch has no need any more because a 35mm full film digital reaches nearly the same resolution...(but he will proceed with 4x5 because he like it)
The last issue he mentioned was : The Hassi is superior against 35mm digital Nikon (and superior concerning Delta 4x5 inch) but in comparison to 35mm it is not an immense profit (so he wondered and relativeted in regard of the much higher pricing of the digital Hassi!
The last he mentioned sounds quite logical to me (remember in 2012 digital midt format used smaler sensors in comparison of today [~ 50% more space in relation to full frame digital] to that time].
And at the very end he discribed he scanned his films with an Epson flatbed scanner.

here is the short version (missing Hassi comparison/use of Portra400/missing additional details of the bridge railing)

with regards
PS : His conclusions should be wrong from my point! His comparison is done with very much entusiasm and he made a very fine job.
But (just from my point - some of you may see this different) his approach is REAL uncientific.
Because of what ?

....because of he was "just" comparing 3 different digital sensors between :
1) ....the 35mm sensor of his Nikon D800
2)......the ~32mm x 40mm sensor of the digital 2012 Hassi
3)......the scanning unit of his Epson700
that has nothing to tell about the films he used..





.DO YOU AGREE ?
PPS : Have fun with translation of the article of that Cologne guy and you may feel like me - such often
