This lens needs to be stoped down. for corner to corner sharpness without shift, you need f8. For more than 5mm of shift you need f11. Once stoped down it is very very sharp.
When shooting in portrait using 10 or 12 mm of shift the very top of the image will soft.
There is light falloff when shifted in portrait and landscape, (obvious on blue sky).
I will start using a perspex sheet and using LLC in Capture one.
There is alot of barrel distortion. Very annoying because It cant be easily corrected if shift is applied.
It also flares easily, especialy if a light source is in the picture. This can be random blobs of color or aperture shapes emanating from the light sorce.
when focusing close the focal length increases alot.
The lens can only be rotated 90 degrees so panoramas with rise or fall is not posable, not good.
The movements are not geared so have to be locked once applied. Very annoying as it is one extra step and can be fiddly.
However non geared movements are an advantage when when hand held. The A99 viewfinder has a very good leveling function.
This alows me to pan up and down with the shift.
No chip so no image stabilization.
There is one thing that has caused me to miss shots. The lens focuses past infinity, unlike all other manual focus lenses I have used. This is realy annoying as 90% of the time I want to focus at infinity.
Movements can move in the camera bag so you have to make shore that they are all 0 before taking photograph. (
Good lens but some things but some annoying things.
