Throughout the history of modern photography, there are few lenses that have garnered almost universal praise from photographers – a tough bunch to get to agree on anything gear related. One of those lenses is the Carl Zeiss Planar 80mm f/2 for the Contax 645 medium format system. A quick Google search will return many reviews in praise of the Planar and its unique and beautiful rendering that came to define the look of wedding photography in particular. I’ve used the lens on and off over the past 10 years to shoot everything from live music to portraits and weddings, and there is no denying the special character it produces.Read More
One of the most unique features of the Sony mirrorless platform is its ability to mount, and in many cases autofocus, almost any legacy lens. I’ve written in the past about the Techart Golden Eagle (CONTAX G) and Techart Pro (Leica M) adapters. Next up is the Fringer CONTAX N/645 Sony E mount adapter.
From the earliest days of the mirrorless movement, photographers have enjoyed the ability to adapt manual focus lenses made for various legacy camera mounts to their new systems. With their electronic viewfinders and focusing aids, mirrorless cameras are uniquely suited for the task of manual focusing older lenses. As one of those early adopters, I adapted every rangefinder or legacy SLR lens I could get my hands on.
The results were satisfying but manual focusing can be challenging for moving subjects or for those with poor eyesight. Thanks to the technology in the new Sony Alpha series mirrorless cameras – specifically those cameras with on-sensor phase detection autofocus – and the ingenuity of a small company in Hong Kong, we now have the ability to autofocus almost any manual focus lens manufactured over the past 75 years for the 35mm format.
This wizardry is delivered via a new smart adapter called the Techart Pro – I’m calling it TAP for short – for Sony’s latest generation of phase detect autofocus (PDAF) cameras: the a7RII, a7II and a6300. Don’t bother trying it with any previous Sony models but we might assume that future Sony PDAF cameras should be compatible. Out of the box, the adapter supports lenses made for Leica M mount, but due to the short flange distance of that platform, there is plenty of room for an additional adapter to stack on the TAP, thus increasing the mount compatibility to support: ALPA, Canon FD and EF, Contarex CRX, Contax/Yashica (C/Y), DKL, Exakta, Leica R, M42, Minolta MD, Nikon F, Olympus OM and Pentax K. These additional adapters can be purchased from Techart or perhaps more cheaply on eBay or Amazon. The TAP itself costs $349 and can be ordered directly from the manufacturer.
The manufacturer claims that TAP can focus a lens as large as 700g but for my purposes, I’m primarily looking at small and light rangefinder lenses as they maximize the compact potential of mirrorless. For this review I’m using the following selection of Zeiss ZM lenses:
- Zeiss 35mm f/1.4 Distagon T* ZM
- Zeiss 35mm f/2.8 C Biogon T* ZM
- Zeiss 50mm f/1.5 C Sonnar T* ZM
- Zeiss 50mm f/2 Planar T* ZM
- Zeiss 85mm f/4 Tele Tessar T* ZM
