I am sexy as hell, awesome as hell, and what the hell.
My Self-Summary
So, here's the deal, this is supposed to describe who I am, but do
any of us really know who we are? I think we all have a general
idea, but I don't know if anybody really knows who they are. People
always describe themselves by personality traits and physical
traits, but is that what makes them who they are? It certainly has
an impact, but it's not the ultimate answer. So, if you want my
traits, look at my pictures and keep reading. If you really care to
know who I am there's no better way to find out than to speak with
me. Go ahead, message me. I guarantee I'll get back to you no
matter what you say to me. Plus, I love getting messages and I love
talking to people. So, find out for yourself who I really am.
Now, some useless text so I can get a higher percentage for having
1,000 words in my profile. Yeah, I'm a cheater, but you don't have
to read it.
There is an enduring fascination for limits in photographic culture
and technique. The drive to engineer and use the fastest film
speed, the highest shutter speed, the shortest focal length, the
quickest motor-drive and the fastest lens continues till this very
moment. In several cases, the need to push a limit is sensible, but
in many cases it is not. Every time you extend a limit, you will
approaching another one, Most parameters are part of a system of
mutually influencing forces. Faster emulsion sensitivity implies
larger grain sizes, increasing the signal to noise ratio of a
sensor will also increase the noise and a compact zoom lens implies
a smaller aperture.
Pushing back frontiers is not the province of the Startrek crew
exclusively. In the photographic industry mechanical and optical
designers and engineers have relentless opened up new horizons. But
sometimes a natural limit is being encountered. The top speed of
the horizontally running focal plane shutter had been fixed at
1/1000 of a second for a very long time. With improvements it has
been possible to push the top speed to 1/2000, but then the adverse
forces start to counter act any further progress. In this case the
physical boundaries and possibilities can be calculated and
predicted with some precision and confidence.
Lens designers are working with a larger range of uncertainties.
Optical improvements do not advance in a linear fashion. Too many
variables and constraints must be accounted for.
This state of affairs is particularly true for that specific class
of lenses that are adorned with the title of superfast lens. In the
current context this applies to standard lenses with a maximum
aperture wider than 1:1.4. In most cases the aperture has been set
at 1:1.2. Only a very few lenses have been designed in the wide
angle or short telephoto category with apertures of 1:1.2. But the
main battleground for all manufacturers has been the standard lens.
There are practical, and optical arguments for this choice. For a
long period the standard lens (with focal length between 50mm and
58mm, sometimes stretched to 60mm) has been the pre-eminent choice
for documentary available light photography. It is in these
circumstances that the light collecting power of the high speed
lens was most required. Optically the balance between bulk and
speed could just be held, in particular with the inherently bigger
slr-lenses.
The race for the fastest lens started in Japan in 1953 with the
introduction of the Zunow 1.1/50mm lens, followed in 1954 with the
Fujinon 1.2/50mm. Both lenses were for the Canon and Leica CRF with
screw thread mounts. In those days the fastest normal lens had an
aperture of 1:1.5 and then a 1.1 was really impressive. A very high
speed lens suited the available light photograpers who had to cope
with slow speed films and very coarse grained higher speed ones,
like the Agfa Isopan Ultra or Record. And then one stop more of
lens speed implied one higher shutter speed or added exposure in
the shadows. Canon and Nikon responded in 1956 with a 1.2/50mm lens
with seven elements (canon) and a 1.1/50mm lens with nine elements
(Nikon). At that moment in time both Nikon and Canon were already
focused on the SLR concept, but Canon did introduce the 0.95/50mm
lens for the Canon 7 in 1961 to demonstrate their prowess in
matters optical. No more very high speed normal rangefinder lenses
were made in Japan until 1999 when Konica produced the special
edition 1.2/60mm lens for M-mount.
Canon introduced a 1.2/58mm lens for the Canonflex and a 1.2/58mm
lens with aspherical surfaces in 1971. The first series used
aspherical surfaces that were grinded by machines that were
manually operated. Only later (but long before Leica) did Canon
switch to a fully automatic grinding process.
Canon’s 1:0.95 lens “holds razor sharpness even at full aperture”
(original excerpt from advertisement), but this statement is quite
optimistic. In fact the Canon lens wide open is a good practical
example of the working of spherical aberration. The sales brochure
of Canon also describes the lens as being four times brighter than
the human eye. Here Canon is a bit too modest. The Leica brochure
of the Noctilux 1:1/50mm describes the lens as being even faster
than the human eye. Studies of the eye have revealed that the
maximum aperture of the eye lays between 1: 2.4 to 1:6.8 depending
on age and situation. The Summarit line of lenses equals the
maximum aperture of the eye.
The quest for superfast standard lenses has always been associated
with a large dose of prestige. The availability of a very high
speed lens has always been seen as the icing on the cake. A camera
system with superfast lenses was accepted as a true professional
product. Many camera and lens manufacturers have been producing
standard lenses with apertures ranging from 1:0.95 to 1:1.2 and
with focal lengths from 50 to 60mm. These lenses were made for CRFs
and SLRs. The marketing argument has been focused on the use in low
ambient/natural light or even the absence of illumination where the
just hand-holdable shutter speed could be the dividing line between
a good and a lost picture. A high speed film where the sensitivity
threshold had been pushed to the maximum level was also a trick of
the trade. Working at the limit of the possible has its own charm
and knowing that you are using the best lens adds to this mood. A
superfast lens is loaded with aberrations and very difficult to
manufacture within the required tolerances that the design demands
to tame the optical rays.
Almost every design relied on spherical lens surfaces and the
designer needed additional lens elements and more exotic properties
and/or daring shapes to get a decent quality at the widest
apertures. The pictures that could be made with these lenses could
be described as acceptable only with a benevolent approach. Canon
went over the top with its 0.95/50mm lens for its rangefinder
camera. On the other hand we have learned from the Startrek series
that you need to go where no one else has gone before in order to
improve your knowledge and experience.
Around 1970 lens design had been improved, but the only rangefinder
left was the Leica. The lens mounts for slr-cameras are inherently
bigger and most manufacturers of SLR lenses have stayed on the safe
side of 1:1.2, and often used aspherical lens surfaces to improve
the image quality. Since the advent of digital cameras the interest
in superfast lenses has become marginal. Only Canon has produced a
1:1 design for the EOS series, but the most recent incarnation of
this lens has its aperture reduced to 1:1.2.
The competition in the SLR arena for the highest speed lens
continued from 1960 to 1985 between several manufacturers, but the
CRF scene was abandoned around 1965 leaving Leitz as the sole
survivor. Undoubtedly the Leitz designers knew about the Canon 0.95
lens and were aware of the need to produce a superfast lens
themselves. Their research into the design options indicated that
the only solution for a lens that combined a compact mount with
good performance was to use aspherical surfaces. The aperture of
the original Noctilux was set to 1:1.2. A wider aperture required a
bigger mount and it might also be assumed that the size of the lens
elements was too large for the aspherical grinding process.
The Noctilux had internal competition from the Summilux 1:1.4/50mm
that offered comparable performance at a much lower price. Still
the 50% additional light that falls on the film surface could
become important. When working in very low light levels it makes
sense to put the minimum exposure just on the edge of the toe area
of the characteristic curve of the film. Here any additional light
that can be used to activate the AgX crystals is welcome. Nowadays
the S-shaped curve that for such a long period in photographic
technique defined the tonal reproduction has been made obsolete by
digital capture where a linear response is the normal case.
The successor of the original Noctilux widened the maximum aperture
to 1:1 and used only spherical surfaces. The performance wide open
is quite good and much better than what the Canon 0.95 offered.
Both lenses used seven elements and no doubt the new glass types
available to the Leica designers and their experience with high
speed CRF lenses gave the Noct-design this much improved
performance.

Thinking about living it. I'm unsuccessful so far.
I’m really good at
I'm really good at being really good at things.
The first things people usually notice about me
Well, recently it's everything. People who haven't seen me in a
whole always look at me in shock and say they don't recognize me or
they actually ask someone else who I am and then look at me shocked
when they find out. I guess I look really different and dress
different than I used to. It makes me feel good about myself. But,
other than that I don't know what people notice about me as far as
first impressions go, so do me a favor and tell me so I know. I
won't ignore your message like some other snobby, stuck-up bitches
on this website.
My favorite books, movies, music, and food
I'm all over the map with this one, and there's just too much to
list. I know what I like, but I'm usually up for trying something
new and different.
The six things I could never do without
Humor,
friends,
soap,
art in all forms, toilet paper, and

I spend a lot of time thinking about
Everything. I think too much. And I wish I had the balls to do
something completely crazy.
On a typical Friday night I am
At the movies. I love
movies. I hope to make movies some day.
The most private thing I’m willing to admit here
I don't really know what to put here. Just ask me something and
I'll most likely tell you. I'm an open book.
You should message me if
You're alive. And you have something to say. So, that pretty much
includes everyone with a working brain. Do your damnedest, ya
bastards.
