Here's something a bit out of the ordinary. Recently, I acquired a tilting adapter for Pentacon Six lenses to fit the EF mount. As you can see from my list, I have a LOT of Pentacon Six-mount lenses. For this picture, I chose:
Carl Zeiss Jena Biometar 80mm/2.8, Pentacon Six
which was made as the normal lens for the medium-format Pentacon Six camera. That camera was later reincarnated as the Exakta 66, and came with Schneider lenses. The normal lenses supplied with that camera were reskinned versions of this lens until Schneider retasked one of its Xenotar lenses for the duty. This lens is a five-element Planar design, and the design is rather old, though this lens dates from 1983. The build quality and styling of the lens is similar to the Zeiss Jena Sonnars pictured in my previous post.
As a medium-format lens, it has an 80mm+ image circle and can thus take the 8-degree tilt of the adapter in stride. The tilting adapter maintains infinity focus and when not tilted works fine as a conventional adapter, though it does not have a focus-confirm chip. I do have a P6-EF adapter with a focus-confirm chip, and one without. I can even adapt these lenses to my Pentax 645.
The adapter sells for $129 from Kiev Camera. It is described and can be bought here.
In the image, the lens was tilted to the left 8 degrees to turn the focus plane to run along the fence. The effect cannot be duplicated in Photoshop, and it would take an unacceptably (or infeasibly) small aperture to achieve the needed depth of field in any case. The lens was set to f/5.6, the white balance was 5000K, and there was no exposure compensation in the conversion from raw. The camera was a 5D, in Av mode. The shutter speed was 1/4000 at ISO400, and I really stretched my technique by hand-holding it at that speed.
The Biometar is a simply outstanding lens. Other images from the same session show critical sharpness at f/8 on a par with any of my other lenses.
More on the adapter: I have a Hartblei PCS lens in 45mm, based on Ukrainian glass. That shift lens has rotation, and on this adapter, would provide independent rotation for the shift and the tilt. I have not yet experimented with that combination. That lens is available used in the coupla-hundred range. Need a cheap alternative to the Canon 45 and 90mm TS/E lenses? Here you go.
