Oprema Jena’s 58mm F2 Biotar Lens Will Have 17 Aperture Blades

We posted recently about the rumored and then confirmed revival of the legendary 58mm Biotar lens by Oprema Jena – a company founded by the same people behind Myer Optik. The company has set out to revive old legendary lenses, much in the same way their sister company Myer Optik has, and their second lens is the Biotar 58mm F2, for which they just launched their Indiegogo Campaign.

Among the interesting information gleaned from the Indiegogo campaign page is the revelation that the 58mm F2 Biotar will have an astounding 17 aperture blades. This is a huge number compared to most modern lenses, and will ensure an almost perfectly circular aperture opening throughout the aperture range. This will supposedly result in a cleaner, creamier, less distracting bokeh – something that portrait photographers will no doubt like the idea of.

Oprema Jena Adds the 58mm f2 Biotar as a Bundle Option With the 75mm f1.8

Oprema Optik announced earlier on that they’re planning on bringing back the legendary 75mm f1.8 Jena Biotar lens; but now they’ve got news of adding the 58mm f2 Biotar to the lineup. In an update, the company is announcing pre-production 58mm f2 Biotar lenses that will be added as a bundle option. The 58mm is also quite legendary and some versions had 13 aperture blades while others even had 17. This focal length has also been coming back into style in the past few years as many not-quite-50mm lenses are seeing a rise due to being better for portraiture but still not as long as an 85mm lens.

Review: Zeiss 75mm f1.5 Biotar – the LEGENDARY Original Version

When a door closes, a window opens. I was expecting to be loaned an M-mount lens, or at the very least, a lens with an M-mount adapter. Instead, what I received from the UPS delivery man was an Exakta-mount lens with a Sony E-mount adapter.

Exakta? I haven’t seen one of those since high school? I guess I won’t be shooting with a Leica M10.

The specific lens I was loaned was a Zeiss 75mm f1.5 Biotar (circa 1939 to 1960), which just happened to also be the same lens Oprema used to base the design of their new 75 Biotar. In case you haven’t heard, Oprema is the company that’s bringing back the 75 Biotar. They asked me if I was interested in writing about it. I accepted the opportunity, because I was curious. When I first heard the announcement, I was going to invest in an M-mount version of this legendary lens. But then, I discovered on eBay how much of a premium legendary demanded, and thus quickly came back to my senses.

Oddly in this case, legendary also meant the lens I was loaned came attached with a Sony E-mount adapter? That was completely unexpected. But then, it didn’t matter. In the end, it worked out all the same… opening doors with a full frame Sony.

Now those reports have been officially addressed by a company called Oprema Jena, a sister company to Myer Optik, in an email both confirming the reports about the development of the lens and explaining those involved in the project.

They make or have made optical lenses for virtually every purpose and these days their lenses can be mounted to almost every major camera brand. As such, they have a deep history and have had many well-loved lens lines come and go over the years. One of those is the legendary Biotar line. Continue reading…

This Vintage Lens Has Way More Aperture Blades Than Modern Lenses

While lots of us tend to geek out about how amazing many modern day lenses are, videographers love the look of vintage glass–especially for the bokeh. There’s a great reason for it besides how they tend to work with the sensor. But many years ago, I purchased a Zeiss Jena Biotar 58mm f2 with an adapter to Micro Four Thirds. On the old Panasonic GH2, it rendered results that looked beautiful. But that’s a Four Thirds sensor, and just yesterday I purchased an adapter for the lens to mount onto a Sony E Mount Full Frame camera.

This lens is an Exacta mount lens and still works very well. But one of the best things about the lens is the 17 or so aperture blades that it has.
