Testing Lens Alignment

A year without new gear hasn’t been really successful. And although we have seen a lot of new equipment this year, there was nothing to merit a complete system change (to the Sony mirrorless or the Pentax 645, for example).

My target for testing lens alignment. Almost a nice image in the autumn fog.

After the disappointing test of the Nikon 24-70 f/2.8 VR, I thus treated myself to a Zeiss Distagon T* 25 mm f/2.0. Great deals can be had on these “classic line” Zeiss lenses, because they will be replaced by the Milvus lenses. The Milvus 50 f/1.4 and 85 f/1.4 are new designs, while the others are basically avatars in an Otus gestalt.

Four Ways to 85 mm: Three Nikon Lenses and the Carl Zeiss Planar for the Hasselblad V-Series

Fighting hard against GAS (Gear Acquisition Syndrome), I still have four ways to arrive at 85 mm focal length. I may therefore check out some widespread myths about lenses: 1) Prime lenses are better than zooms. 2) Vintage lenses are ill suited for digital sensors because they are not telecentric, that is, the ray angles at the edges of the sensor exceed the acceptance angle of the microlenses, which results in reduction of color saturation, and color fringes. 3) The 35 mm lenses have a better resolution than medium and large-format lenses, simply because they need to cover only a smaller caputure area and can therefore be made from more expensive glass.

Lenses

From left to right: Nikon AF-S 70-200 f/2.8 G ED VR II, Nikon AF-S 85 f/1.8 G, Nikon PC-E 85 f/2.8 Micro, Hasselblad Zeiss CF 80 f/2.8 Planar T* mounted on a Photodiox adapter.

The contestants

  • Nikon AF-S 70-200 f/2.8 G ED VR II
  • Nikon AF-S 85 f/1.8 G
  • Nikon PC-E 85 f/2.8 Micro
  • Hasselblad Zeiss CF 80 f/2.8 Planar T* mounted on a Photodiox adapter

I hated the Nikon AFS 70-200 f/2.8 and the Canon equivalent, because having set up my large format camera, I was more than once harassed by photographers carrying these lenses. Considering their form factor it does not need much to imagine what some guys are compensating for.
