If it were camera shake, the unsharpness would have been on the same side all over the picture. The detail shots clearly demonstrate the opposite.

There is still an airworthy Li-2 (HA-LIX) based in Hungary, although she flies in post-war civil colours.

Seen in 2006 at the Aviodrome in the Netherlands.

The performance of your lens certainly is not within acceptable tolerance limits. It looks like one or more lens elements are out of alignment. Has the lens been dropped or knocked?

If the lens has been bought new, I would insist on immediate replacement by another example. Otherwise the lens should be send in for inspection and repair.

I wonder if Duxford and Shuttleworth know about these airspace restrictions and will have to re-arrange the show’s they’ve organised during that period and change the dates published on their web sites?. :rolleyes:

Duxford already did for the Flying Legends show! See information on The Fighter Collection site. http://fighter-collection.com/pages.php

“tilt and shift functions”

How does that work?

Will a virtual camera with the same format/focal length be able to make the same perspective corrections with tilt and shift functions produce an image of a 3D virtual cockpit that fits the original photo?

A standard camera with a normal lens doesn’t allow for perspective corrections, because the lens axis is always exactly perpendicular to the film/sensor centre. The lens and film panels of the technical or view-camera’s can be moved upward, downward, sideways and even rotated. This makes it possible to modify the plane of maximum sharpness, which doesn’t necessarily need to be perpendicular to the film plane, and to make perspective corrections, e.g. to correct converging lines in the picture which actually should be parallel.

Some modern camera manufacturers, especially Canon and Nikon, offer tilt-and-shift lenses to correct the perspective as well. However, compared to view camera’s, the corrections are limited because the film/sensor-plane will always remain fixed. An advantage of 35mm camera’s and DSLR’s is that the depth of field of the lenses is greater than with a comparable focal length of large format view camera’s.

Tilt-and-shift lenses are very expensive. To a limited degree perspective correction can also be applied in the post-processing of digital images. In Adobe Photoshop you can find this under Filters / Distortion / Lens correction. Also a program or PS plug-in as PT lens enable perspective corrections.

Although top grade wide-angle lenses for DSLR’s, like Nikon’s AF-G f/2.8 14-24mm, offer superb edge-to-edge sharpness and very good depth of field (depending on the aperture setting), it could be desirable to even further improve the depth of field in the final picture. This can be achieved by using the stack-focus technique. With this technique a number of photo’s are made from the exact same position and aperture settings, but with different distance settings. With special software these photo’s will be merged into a single picture with maximum depth of field. If perspective correction would be needed, this should be done to the final merged image.

With a good DSLR, combined with a very good wide-angle lens and proper technique, it should be possible to replicate the original 1940’s photo. To remove glare and reflections in the dials, it could be desirable to use a polarization filter.
