To get proper depth of field in INON UFL-MR130 EFS60 Underwater Micro Semi-Fisheye Relay Lens
Posted 16 July 2010 - 03:33 PM
When I began to use, I just adjusted distance of focus simply on foreground subject. After that, I compare with Tokina 10-17 macro wide shot , I could not find any advantage of this long nose lens over Tokina combo setting( plus teleconverter). But recently I realized that to get good sharpness of background subject I should adjust focus distance on foreground subject as far as possible. After all I could get better sharpness of background subjects than my tokina 10-17 combo set. All those are pictures taken by lnon long nose lens.

Thxs for the info Cho. I am one of the frustrated person too. Can you elaborate what you mean by "I should adjust focus distance on foreground subject as far as possible"
Thanks in advance
Sorry maybe it was not enough that I explain about my concepts on how to adjust focus distance. Actually this long nose lens has great depth of field.It has longer infocus area than other ordinary lens. I mean main subject should be located at the point of nearest infocus area from camera , not center of infocus area.

It would be not easy to make subject be placed at just front site of infocus area exactly. In my opinion, for this reason, focusing braketting(?) would be needed as the mention of Timmoranuk. Anyway subject should be placed on very front point of infocus area,not exceeding of infocus limit.
