The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
Eric,
Are you referring to the issue folks find with lens designed for APS-C sensors on a full frame body or is it particular to fish-eyes?
JW
have seen that black edge scenario when using lenses designed for the small format sensors on a full frame camera as the image is only sized for APS-C. In other words the image does not fill the sensor. My assumption was that Artie was shooting digital but would still apply with a
Film camera as they are the standard for "full frame".
