Fie! When I submitted prints for consideration by PT, all were full-frame. I
mean, jeez, a stated aim was to show how the lens images -- delivering a hunk
chopped out of the middle would seem somewhat inconsistent with that aim.
And... call me persnickety or unrealistic, but I tend to consider a photo which
doesn't work full-frame, as I shot it, pretty much a failure. That doesn't mean
I'll never crop when necessary, to salvage something useful -- but I just don't
feel particularly proud about it.
That having been said, on the subject of the Noct's vignetting: I've come to
expect it, and build it into my expectations of the finished product, of
course; but often, shooting in the dim, it just isn't obvious anyway. To
illustrate, I've slapped the two submissions I made to PT which happen
already to have been scanned into a page for your viewing delectation.
These are full-frame scans from the negatives; the only cropping I've done is
a few pixels off an edge or two to trim off sloppy-scan artifacts. The room
was dark (what may look like daylight outside is the glow of a
none-too-enthusiastic streetlamp), and the presumably dramatic three stops'
corner loss in our chum the Noctilux is just lost in the noise. Have a look
at:

It'd be cool if many of the folk who submitted stuff to PT did this -- I'd
like to see some of those pictures better, and we've all been saying they were
too damn' small in the magazine. I expect we wouldn't have any impact on the
issue's sales at this late date...
