i shot from 18mm - 1400mm. if you are interested. i was not trying for IQ. just an example of different focal lengths.

FOV

edit: i'd say the house is about a mile away and downtown dallas between 8 % 10 miles. it was a hazy day.

Good examples despite the haze.

If you try a similar exercise using a large format camera and compare the results from a small format, using the same focal length lenses on both, you will find that the crop from the large format that equates to the field of view from the small will produce almost identical images.

Just a piece of otherwise useless information.

of coarse you would. focal length is focal length. only thing that changes is the crop factor..

But how few photographers seem to be aware of that! Believe me, I've heard high level professionals at a London Uni refresher course querying a lecturer on this topic.

it's like using a 1:1 macro. 1:1 is 1:1. all you get in the different formats is more background.
1:1 is 1:1 is still 1:1
