Zuiko 50mm + Inon UCL-165M67

[Mr_Pyro]

Hi!
I've just orderd an Inon UCL-165M67 closeup lens for my Inon 50mm macro port.

What focal lenth will this combination achive?
Would stacking two Inon closeuplenses produce to much image distortion or focus problems? Anyone tried this?

Images produced with zuiko 50mm + Inon UCL-165M67 combo would be much apreciated to have look at!!!

Cheers

Adding one or two Inons will allow you to get closer to the subject, not too sure in the equivalent focal lenght though. Not much distortion with one or two, I will have a look later to see if I can find some images. I have definitely used this combo very successfully.

With one Inon 165

Not the best subject, 50mm plus two Inon 165's

Very nice stuff Andy.

My understanding is that the Inon 165 is a +6.5 diopter. The 50 macro has a 24 degree angle of view, with a +10 diopter it would have a 12 degree AOV. So the +6.5 would be in the 19-20 degree AOV range. The downside to any diopter is that the distance between the end of the lens in this case the diopter and the subject is reduced. The more magnification the closer you will be to the subject given the same focus distance set on the lens. I like to use the Inon 165 in combination with the X1.4 tele converter. The tele converter increases the distance between the lens and subject while reducing the AOV, when the Inon 165 is added the AOV is reduced further but the tele helps retain better distance to subject.

The Inon port is a great to use with this diopter, when the lens is fully extended it sits very close to the port glass giving max distance to the subject.

Thanks for excelent info guys!
Sweet photos Andy!

So, there wouldn't be any major problems using two Inons, except maybe tricky strobe placement due to the subject beeing very close to the lens.

I realy like the possiblity to use adon lenses with the 50mm.
Does any one have some experience the other way around, ie, using a wideangle adapter with the 50mm? Could be nice to have if a turtle or shark comes by, when one is looking for small critters.
