It works fine with no other hacks! Neil, Can you give some details of what you did in Pacifist? I really think it should run Aperture reasonably well if I could only get past the check.
I found that the offsets were wrong — just search for the first and second occurrences of the first hex string, and replace, and then the next occurrence of the other string, and replace. And make sure you are working on a backup of that file, so you can go back and try again if it fails. First off — you do realise that this post is for Aperture 1. The values for 1. Having said that, if you have an Aperture. Only the Aperture Application installer bothers to check compatibility; all of the support packages just go in.

Chris November 4, The competing Summarex was also quite heavy at g versus the g Biotar. During the Post War period it became a matter of prestige for German lens designers to create a fast telephoto or portrait lens. Then in Nikon released their Nippon Kogaku K. Nikon Nikkor-S. However, no other lens has reached the status of the 75mm Biotar amongst users and collectors.
It should be noted that nearly all these lenses were designed for rangefinder cameras, while the Zeiss Biotar 75mm except for copies in Contax RF mount was designed and produced for SLR cameras.
This camera was also the first camera to use what is now known as the M42 screw mount alternatively called the Universal Screw Mount or Pentax mount. It was the very first 35mm eye-level single lens reflex with a glass prism finder and interchangeable lenses, debuting an astounding nine years before the Nikon F , Canonflex, and other eye-level SLRs with interchangeable lenses and focal-plane shutters.
Among the many different versions of this lens, these are highly sought after and reputed to be of the highest optical quality of all versions of the 75mm Biotar. Primarily this is because the lens elements were produced using the high-refractive lanthanum-containing Schott glass that only Zeiss had access to.
These lenses also have twelve aperture blades instead of the ten blades found in Version three. Sadly, the partition of Germany placed the Jena factory where the 75mm Biotar was produced in the Soviet Sector, which later became the D. At first there was cooperation between Zeiss Oberkochen in the West, and Carl Zeiss Jena in the East, but eventually Zeiss Oberkochen filed a court case to prevent the use of the pre-war Zeiss trade names.
This dispute and the growing animosity between the USA and the Soviets made it difficult for the Biotar to be sold and marketed in the West, and production ceased in The Gauss models designed at Carl Zeiss Oberkochen never used the Biotar name, but kept the older Planar brand name for historical and political reasons. In the Kine-Exakta brochure of it is referred to as the Biotar ,5 but the designation of the lens changed multiple times over the years, for a variety of reasons.
The first version stands out immediately to possess a small and compact barrel, one centimetre less in length than the next version , a weight of g and a front lens of 55mm. The minimum focus, with distance scale expressed only in meters, is located at 90cm. However, the front graphics, with the fascinating design of the depth-of-field scale, make it immediately unmistakable.
One amazing attribute of this lens is that it has eighteen aperture blades, thus being capable of creating a circular lens opening continuously from f1. This version and version two had manual aperture selection. These are reputed to be the best lenses in terms of optical quality. The lens ring changed from 7.
The pre-selection ring is located in the front panel above the diaphragm ring. The third version of the Biotar had a front lens of 55mm in diameter, a solid barrel with a heavily knurled or scalloped focus ring, a double distance scale, a minimum focus at 0.
Although Version Three predominantly had ten aperture blades, the earliest preset models produced in M42 mount for the Contax S camera came with twelve aperture blades.
The Fat Version was commonly used for x-ray and copy machines, so they can focus as close as the Thin Version, or closer, just by adjusting infinity to closer than infinity so that close focus is as close as needed.
The last known example was serial number 8,,, produced in Exakta mount in However, the catalogue for the Exacta VX still shows the lens for sale, so the factory must still have had stock on hand even after production ceased. Recently Dr. In they established another company, Oprema Jena, which offered a modern version of the 75mm Biotar, the Oprema Jena Biotar 1.
In , a press statement from the company sadly informed us that Dr. Immes had been grievously injured in a car accident and that the company went into liquidation. I have no figures for how many versions of this lens were produced, but the company website is still online, and the video above gives a nice overview of the lens. From to only 16, lenses were produced through the three versions, across six different mounts.
The rarest examples were made in coupled Leica screw mount and Contax rangefinder mounts, and they sell for very high prices due to their value to collectors, but optically they are no different to examples in other mounts.
Optically the M42 and Exa Mount Version Two lenses with twelve aperture blades are reputed to be best, although I have seen side by side comparisons and the difference is minimal. Production numbers in descending order of units produced, years of production, and serial numbers where available in various mounts follow.
Contax rangefinder; ; units, starting from serial no. Leica Thread Mount; ; Only 3 units, serial nos. However, researching past auctions and current sales I have discovered three.
It does weigh more than my average 50mm lenses, but I like the weight. It feels solid and steady when shooting portraits by hand. The large knurled focus ring, which is distinctive of the s German silver lens that I love, makes focusing a joy, and the focus is dampened perfectly, smooth and easy to use. Unlike modern super-sharp lenses that highlight every pore of the skin, the Biotar 75mm is much more forgiving in portraits, and the softness when shot wide open creates images reminiscent of portraits from the Golden Age Hollywood.
There are many bokeh lenses that are one trick ponies. These are used often for shooting portraits in low light to create a swirling background or total universal blur. But the Biotar 75 is capable of producing several types of images. Photos by Cheyenne Morrison ]. At close distances, one to two meters, it can make classic portraits with background out-of-focus areas that resemble a Monet oil painting.
These show just a hint of swirl, the attached photo of Tim at a waterfall best exhibits this look which reminds me of the rendition of my Schneider-Kreuznach Xenon.
However, step back a bit and shoot the subject at five meters and position the background so that dappled light shines through trees behind the subject and we get incredible rendition of the swirly bokeh effect that has made lenses like the 58mm Biotar and the Helios 44 so renowned. His magnificent photos show just how radically different the bokeh presents when using the Biotar 75mm on a digital camera. Bokeh is very pronounced, with hard edged bokeh balls as opposed to the images that I have shot on film where the bokeh is much softer.
I know that the bokeh balls trend is a matter of taste; many people love the look, and a slew of companies are even recreating vintage lenses to cater to this taste. But there are just as many people who hate that look and find it to be a distraction. As the critics rightly point out, the whole point of a portrait is to highlight the subject, not to emphasize the out-of-focus area. I prefer the images produced with the Biotar 75mm on film. But I also love the shots on digital.
The M42 mount does not hit the mirror when using a Canon 5D, although I cannot vouch for other cameras. Know that the M42 version is easier to adapt, but that it also commands a premium price. The fact that the Biotar 75mm was the pinnacle of lens design for many postwar camera systems meant that vintage camera collectors were already paying a premium for the lens even before its renaissance as a classic portrait lens for modern day photographers.
The really sought after lens is the postwar Version Two with chromed steel body and eighteen aperture blades. A working Biotar 75mm in good optical condition is a fraction of that, and a worthwhile investment for a portrait photographer, as prices will only continue to rise in coming years.

Character counts more than specs, and a lot of modern lenses not all are technical wonders that are very boring. You could also argue that the Weimar republic ended in and that bij Hitler had a firm grip on Germany for at least four years. I would disagree with your summary of the Summarex. Yes it is quite heavy and somewhat prone to flare but a lot of its reputation for this are due to condensation of the essential lubricant from the 20 blade yes really 20 blades diaphragm on the glass surfaces either side of it.
Also it is essential to use the correct lens hood. Once the fogging is cleaned and the diaphragm lubricant replaced with modern non-evaporating silicone grease, the performance improves a lot. For a design, the Summarex is a remarkable performer, with excellent contrast, even when used wide open, as it often is. The Summarex has a reasonably flat focus field and is certainly less curved than the Biotar. For me the huge advantage is the mount. I was however, going to put a new Biotar on order and it is very sad, what happened to the company, after the death of Dr.
