The mount is internally mounted on a T2 mount structure that can be exchanged between lensesHelicoid: YesFlange Focus distance: M42/45.46 mm,Front filter: 46 mm x 0.75 mmIntroduction year: before 1965This lens produced: 1964S/N of test object: 86410227** Mount of test object Image of test object: Transmittance SummaryDefinitions of the parameters belowRange: This Soligor 135mm f/3.5 transmits from 1-80% in an increasing slope from 327nm to 400nm.TVISmax (%) = 87%T400nm (%) = 80%T365nm (%) = 63%This high percentage is an indicator for relatively short exposure time under typical UV-pass filtration peaking around 360 nm or when using 365 nm UV-LED illumination.λUV HMvis(nm) = 352nmλUV HM400(nm) = 350nmλUV Zero(nm) = 327nmThese three values indicate that the lens is marginally working for some shorter wavelength UV-A photography with some filters and the few for this, suitable cameras.Spectral Transmission GraphsUV-NIR, Soligor 135mm f/3.5The transmission measurement accuracy into the end of NIR range is less good due to limitations in the light source. UV, Soligor 135mm f/3.5 UV-Log, Soligor 135mm f/3.5Numerical Spectra Data available: Yes General comments about the UV-reach:tbaFilters and how to use them on this lens:The front filter thread is a 46mm standard filter thread. It is also possible to use rear mounted filters, either in lens mount adapters for mirrorless cameras like Sony A-series etc, or placed directly in the camera.
