Silberra Color films were first introduced in 2019 as an extremely limited edition test batch and only as ISO 100. During the COVID-19 pandemic of 2020-21, Silberra continued to develop the means for producing color films on a more regular basis and beginning in 2021 released three speeds of color films: an ISO 50, 100 and 160, with the Silberra Color 100 being available in both 35mm and 120 at the time of these films' introduction.
Initially not much was known about the manufacture of these films. They are presumably made to spec at the request of Silberra and are their own thing, not another color film repackaged in a Silberra box.
Silberra Color 50 has surprisingly rich colors, especially with its reds and greens, causing some to remark that it reminds them a bit of the Kodachrome look. Personally, we feel like it is similar to Kodak Ektar, but that is perhaps merely because we are more prone to tying it to a modern emulsion. Silberra Color 50 also has incredibly fine grain.
The film is coated onto what feels like a triacetate base but has a much lighter base color than other contemporary color negative films. This may cause some initial color casts in scanning as most modern scanners are calibrated for a deeper orange film base. Silberra also uses recycled film cans that have been shown to be prone to light leaking. A bit more care than usual should be taken when loading this film and subdued light is best.
Pentax Spotmatic II with KMZ 85mm f/1.5 Helios-40
Occasionally, when we get items in for consignment, we are presented with some very tough choices.
Take this Helios-40 85mm f/1.5 lens as an example. This bokeh beast has earned quite the cult following. When it came in for testing, we immediately took it out for a walk on this Spotmatic II, loaded with a roll of Silberra Color 50. We planned to be sharing these sample images with you the same day that we put the lens out on our shelves, but - alas - the test revealed that the lens had a few marks against it: rough focus, fungus in the optics, not focusing quite to infinity, etc. The rough focus was more or less fine, as the focus still worked, it just wasn't as smooth as we'd hoped. The fungus and wear marks on the optics are something we are used to seeing on a lens of this vintage. Not attaining infinity focus really wasn't this lens' fault. Originally, it was made for the Zenit M39 SLR mount and this lens had a roughly machined M39-M42 adapter ring on it. The difference in flange distance between those two camera systems, and the inexactness of the mount adapter, were causing the focusing issue. But still, the question remained - was this enough to pass on the lens or sell it with all of the significant asterisks. We don't like selling equipment that have too long a list of "things you should know," but then again, this was such a cool lens...
The solution we settled on? We opted to put it out for sale after all, though it didn't last long on our shelves. Staff member, Ashley was sufficiently lured in to buying this special lens through all the extensive conversation it was generating around the shop. You can all thank her for taking that bullet for your wallet.
Here are the sample images this lens made with that Silberra Color 50. As you can see, it is nice stuff.
