6910 Zeiss Batis 135mm F2.8. IWF conversion


This is a Van Diemen conversion of a Zeiss Batis 135mm F2.8 using our patented Inverted Wireform™ variable-pitch focus movement to provide a very smooth and reliable focusing movement. This lens has an exceptional close-focus with macro capability but does not reach full 1:1. All of the Zeiss range of IWF conversions benefit from internal focus and are fully geared for motorisation. Lenses are supplied with macro scaling and in PL or LPL mount with other options available on request. This lens is housed in our extended-body design, for which an image is unavailable. The conversion will share a similar design concept to the conversion in the image, but will be longer.
