I agree with Richard. Gonio photography is one of the most difficult
photographic procedures to learn.
As for the lens that you showed, it is a very good lens, but can be
limiting to only the 62 degree mirror which allows you to view pathology in
the angle. If you are looking to be a bit more flexible and also look at
pathology on the iris itself or just behind the iris, I would suggest
looking at the OG3M Three Mirror Universal Lens. I prefer using this lens
most of the time as it allow me to have more choices, especially when I
have multiple nevi to photograph. I also prefer the 18mm contact diameter
lens. Ocular Instruments has this universal lens on their website if you
are interested.
I hope this helps.

I’m assuming by your question that you are just starting out on this quest
to be a gonio-photomicrographer? If so, I think there are just too many
questions to be answered in an on-line forum such as this.
It took me a year of doing a lot of them to get the hang of it, while
having others show me how to do it. Maybe I’m slow, but it was just about
the hardest photographic procedure I learned to do. An OPS workshop on
gonio photography would be a good place to start.
Just my little ol’ retired advice.

Hello, a doctor of ours recommended we try this Gonio lens. Would anyone
be able to provide insight on what a good photographic Gonio lens consists
of? Is there a difference between treatment lenses and photographic?
