Using Filters and/or Diopters behind a (Mini) Domeport?

05 March 2011 - 11:38 AM


I thinking of getting a domeport for wide angle work and i am wondering whether it makes sense to use diopters/filters behind a Dome?

What kind of red filters do use for shooting in natural light with a Dome? i have a 67mm "wet" filters and diopters but dont know if all that makes sense behing a domeport? Shall i screw the "wet" filters directly on the lens using stepup rings, lens diameter is smaller then 67mm.

Using diopters behind a dome possible or sometimes necessary? if yes, when makes it sense and will i loose a lot of optical quality when using diopters? The lenses i gonna use have a relatively small minimum focus distance of 0.25m / 0.82ft and the other of 0.20m /0.66ft

Thank you for your much appreciated answers and help


Panasonic/Leica 45mm Macro in the Olympus PT-EP01/03 Housing for Oly E-PL1/2

25 February 2011 - 04:30 AM


I am wondering if somebody uses the Panasonic/Leica 45mm Macro in the Olympus Housing for the E-PL1/E-PL-2 (PT-EP01 or PT-EP03) with standard flat port.

Does this lens suits in the housing/port and work properly or do you recommend to buy an Athena Macro Port for it? I've read somewhere that the distance between lens and Port Glas is a bit too wide and that it could cause e.g. misfocussing on the port glas.

Many thanx for hints.

best regards
