The Skyllaney Opto-Mechanics MkII conversion of the classic CY 50mm f/1.4 Planar T* is now available.

The first batch of lenses is currently on it’s way to customers who had pre-ordered them. There will be a few lenses left over from batch 1. They will be available for sale on our Ebay store.

We are now opening pre-order requests for the second batch of Planar lenses.

Simply fill out our pre-order request form with your information and choices. After submitting a pre-order request you will be sent an invoice for 50% deposit for the lens. This reserves your lens slot, choice of imperial font colour and leatherette insert choice.

Batch 2 (the next 25 lenses) will be a mixture of:

  • Converting the customer’s existing Planar lens.
  • Buying a pre-converted one from us.

If you will be sending you Planar to us for conversion for Batch 2, it is imperative that it arrives at our office in England by 15th of November, 2020. Any Planars that arrive after this date, may miss the end of year window to be returned back once completed.
Your existing Planar must have no fungus, no oil on the aperture blades, and be in good, usable condition. We cannot accept Planars for conversion at this time that need a service to get them working, such as haze, fungus or mechanical issues.

Batch 2 Planars are expected to ship second week of December, just in time for the holidays. We are ensuring all lenses from Batch 2 arrive with our EU customers before the end of the year, so there is no unexpected customs charges levied due to the United Kingdom leaving the European Union on 1st of January, 2020. This is the reason for a cut-off date if you will be sending your copy in for conversion.

The orders will be completed on a first come first served basis.

Batch 3 will subsequently be ready by March of 2021. All customers for batch 3 lenses will receive their invoices around that time.

Since every Planar conversion is hand assembled, converted and calibrated here in England, there is limited capacity for how many can be delivered for the 2020 Holiday season.

*Please note: We convert used Zeiss 50mm f/1.4 T* Planar lenses for CY mount. The availability of these lenses in various conditions is always a factor. We only sell converted Planars that have excellent to mint condition glass. Any Planars that have fungus, haze, oil on the aperture blades or scratches, are not fit for conversion. However, there may be small cosmetic blemishes on the front exterior body, as these lenses are over 30+ years old. In most cases, we refuse to sell converted lenses that have unsightly aesthetic parts on any of our custom offerings. However, they may have small nicks in the anodising, minor dust inclusion, or other minor cosmetic marks, simply due to the fact it is no longer possible to procure them new.

Dr. Ludwing Bertele (1900-1985)
Optical designer of the original Sonnar lenses

Introducing the Skyllaney: 50mm f/2 ‘Bertele’.
Skyllaney Opto-Mechanics is hard at work developing thier new 50mm f/2 Bertele lens. By 2021, we hope to release our first limited edition run of a 50mm f/2 classic Sonnar formula lens in native M bayonet, which optically is based very closely off the1937 pre-war era design by Dr Ludwig Bertele.
Our version contains the same element radii that were established by the good Doctor in 1937, but marries them with modern AR coatings which have increased contrast and reduced flaring. We also are implementing a 9 bladed 1937 sytle rounded aperture for enhanced bokeh, a high precision brass helicoid, 90-100 degree focus swing from 0.7m to infinity, a high-speed focusing body utilising a finger tab, all kept in a compact body no larger than the v4 cron. It will be initially offered in black anodised (6061 Aluminium) or chrome (Brass) finishes, with an initial run of 150 lenses, with possibly another 100 to follow. Each one will have the front filter ring customisable by the customer with up to 18 characters, in addiiton to ‘ Bertele 50mm f/2’ and the lenses limited run serial number.

Here, at Skyllaney Opto-Mechanics, we have an affection towards Sonnar formula lenses, and we see the desire of our clients to experience these wonderful lenses for themselves. Because of that, we work on entirely restoring classic Contax I and Jupiter 8 lenses.

We have spent many months designing, developing, assembling and testing our custom-built, high precision dual 4 axis CNC machine. The machine has its four main axes (X, Y, Z, A) computer-controlled through CAM control software. It uses anti-backlash lead screws and ball screws, high precision/high torque stepper motors and high voltage drivers. The machine was extensively trammed and tested, the custom backlash systems further tweaked, and then certified using precision dial test indicators. We periodically re-tram it to ensure its continued accuracy.
