Heliopan diopters for Iscorama 54

[kado]

hey guys, first time poster. long time lurker.

im looking to purchase diopters for my iscorama 54.

i know 82mm or greater diopters are hard to find,

but i stumbled upon this site that sells Heliopan diopters

for 82mm, 86mm, and 95mm.

anyone know how well or poorly they perform?

or better yet, if someone is kind enough to sell me a +.5 >82mm diopter. :)

 

thanks.

hi tony,

i'd be interested in the +0.35 82mm and  82mm +0.25.

can you tell me more about them?

i currently have a +1 86mm diopter which covers around 1.5ft to 3ft.

what's the focal distance of each one if paired with the isco54?

im looking to find a weaker diopter that would cover 3ft to the minimum focous distance of the isco54 which is around 2m (6.5ft).

 

edit:

and your price for each?

 

thanks.
