Mitigating Focus Shift in the Field (Nikon D800E + Nikon 14-24)

To Making Sharp Images, I’ve added a triple-focus case study showing how to mitigate focus shift in the field.

Though this study uses the Nikon 14-24mm f/2.8G, it applies to any lens with focus shift (very common), e.g., the Canon 50mm f/1.2L, Zeiss 50/1.4 and 85/1.4 Planars, Nikon 28/1.8G, etc.

This article is essential reading for any photographer not aware of the perils of focus shift (in terms of getting sub-par results). It is not only a case study, but shows the practical considerations in the field.

Not related— I just like the fact that Nikon D800E images make darn fine black and white images too. Basic conversion here using Images => Adjustments => Black and White with Deep Red Filter in Photoshop.

BTW, this post is MOST USEFUL!

DIGLLOYD: That is the intent. I keep hearing from Nikon 14-24 users who are frustrated with its performance. It is a very sharp lens, but with strong focus shift, highly unusual for an ƒ/2.8 lens.
