Okay, another shot at part B.

All taken with a Tamron 16-300mm on my A58.

Having problems posting the right images!

Try again!

All taken with a Tamron 16-300mm on my A58.

Original position 70mm



Closer in 35mm



Original position 16mm



Further away 35 mm



Certainly a far clearer idea of the perspective change in these - but matching the framing was a nightmare!

@Phil Wood: Well done, Phil! Framing is, indeed, difficult... which is part of the point of the assignment The key is to try to match the size of the central subject and let the periphery go where it will. You get a larger sense of the surroundings with the shorter lens and a larger field of focus. Now, on to your next assignment.

Cheers... Brian

Thanks again Brian - hopefully Silhouette will be less problematic, though 'perfectly executed' is an interesting caveat.

Okay, let's go, I'm in a flow... However, got a lasting cold, which holds me home from time to time. Therefor some interior shots today.

Part A: Telecompression

Original Teleshot (203mm)


Cropped WA (24mm)


Part B: Zooming with your feet (actually my butt, as I was sitting on the floor )

First shot @24mm


Second shot @50mm


Third shot @98mm


I'm sorry, my horizon is a bit tilted and the horizon is shaking a bit vertically. My little tripod is not very stable.
All settings, except time, are maintained equal for all shots (f5,6).

Part C to follow.

@Harm vb: Part A is a "clear" (pun intended) pass. The extra DoF on the WA is expected since, DoF is inversely related to the square of focal length at the same aperture and distance from the subject. In order to make the images identical, you would have had to have a remarkably fast WA lens.

For Part B, the objective is to maintain the same field of view with each lens (i.e., the objects at the edges of all three photos should be be the same). It is easier if your first shot is at 50mm and moved closer to the subject for the 24mm shot and further away for the 98mm shot. If the camera is moved along the line exactly perpendicular to center of the first photo, you should be able to get all three photos to have a (more) similar field of view (left-to-right and top-to-bottom). Please try Part B again.

Cheers... Brian
