Skyline of Frankfurt am Main at dusk (2014)

This image shows a panorama which was stitched from eight images in portrait orientation. Due to the high dynamic range of the sensor I only used one exposure and brought back the shadows with Lightroom. The size of the resulting image is 19200 x 6000 pixel.

Luitpoldpark in February (High Pole Shot)

This is the first high pole panorama I shot with the Sony ILCE-7 camera and the Walimex Pro 8mm fisheye lens. The pole is about 5.5m or 18ft high. I used a custom made wireless remote adapter to trigger the camera.

Comparing image crops of Sony LA-EA2 and Sony LA-EA4 on Sony ILCE-7 (with Sony SAL70200G @ 200mm)

Today I did some tests with the two lens adapters Sony LA-EA2 and Sony LA-EA4, which can be used to adapt a lens with a Sony A-mount to a camera with an Sony E-mount. In another article I already compared looks and weigth of the two adapters. In this article I focus on the different image crops when you use the two adapters on a full frame camera with E-mount. I used a Sony ILCE-7 for my tests. On a Sony ILCE-7r the crops are the same, but you get a higher pixel count.

I only tested the Sony 70-200/2.8 (SAL70200G) at 200mm. I used the lens collar of the lens to attach it to a tripod. The lens, the tripod and the subject were not moved after that.

The first image shows the result when using the LA-EA4. The resulting image is the full resolution of the sensor.

For the second image I only exchanged the LA-EA4 with the older LA-EA2. For this image I used the following configuration of the camera: Menu → Custom Settings (gear icon) → 5 → APS-C Size Capture → Off. You can clearly see the shading of the LA-EA2 on the sensor. The maximum manual crop is marked with the green rectangle.

For the next image I only changed one setting in the camera: Menu → Custom Settings (gear icon) → 5 → APS-C Size Capture → On. The resulting image showed an even larger crop than the second image but no shading of the adapter. In postprocessing I superpositioned the two images to be able to mark the camera crop in the second image. This is the result.

In the last image I used the first taken picture and marked the three different crops. The red marker is the LA-EA4, the green marker is the LA-EA2 with maximum manual crop and the blue marker is LA-EA2 with cropping enabled in camera.

The maximum manual crop (which is equivalent to the unshaded area of the sensor) will differ when you use a different lens. And it also differs with different focal lengths of a zoom lens. But this needs some more testing.

Images of shaved Samyang (Bower, Rokinon, Walimex) 8mm fisheye lens attached to Sony A7 (ILCE-7)

In the last article I showed the resulting images on the sensor at the different stages of shaving the Samyang (Bower, Rokinon, Walimex) 8mm/2.8 UMC fisheye lens.

The following picture shows one side of the box of the Walimex version of the lens. It also shows the lens hood in its original state.

The following images show the lens with already shaved lens hood.

Residenz München Kaiserhof

I think this panorama is not one of my most spectacular ones, however I took the image because I was thinking about a reprojection of the scene.
