FF450+ Lens Hood https://www.opsweb.org/forums/posts.aspx?topic=1455936 Sun, 19 Jul 2026 02:09:15 GMT Sat, 27 Oct 2018 07:06:09 GMT Copyright © 2018 Ophthalmic Photographers' Society FF450+ Lens Hood https://www.opsweb.org/forums/posts.aspx?topic=1455936 https://www.opsweb.org/forums/posts.aspx?topic=1455936 Hi ophthalmic imaging experts!

Anyone out there ever experiment with removing the metal lens hood from their FF450?

When going after some of those peripheral lesions it can get in the way and it's far faster to pivot my camera than fiddle with head positioning.  [It's all about speed so we can get back to those urgent OCTs!]

I'm wondering most about flare/lens glare issues since the hood does cone down significantly.

I don't like the thought of losing my lens cap, but i'm sure i can macgyver that.

All input appreciated.

It should be easy enough to find a different way to have a lens cap on there, even if it means making a detailed sketch and having a 3D printer burn one out.

Speed is an important thing, the longer it takes to get the photo, the less patient the patient is, and the quality potential for imaging tends to decrease.

Is there a different way to drop the glare? Overhead lighting being turned off? Different location for room lighting (under cabinet only during capture vice using overhead)? using only reflected light during OCT on matte painted walls to reduce polarized light potential? At the worst if the glare is from external lighting you could drop a sheet over the photographer, camera, and patient and reminisce of the similarity to wet plate collodion photograph capturing processes.
