Stacking Subsee +5 and +10, over kill?
Posted 29 January 2013 - 01:17 PM
Anyway, has anyone try to stack them together even hand held and see what happen? Is it impossible to focus, or the magnification is just not worth it? I'm thinking some situation like tiny shrimp, or fish eggs could use that kind of magnification.

I spke to Reefnet in USA about this as I was interested in stacking their lenses but their advise to me was that there would be come major vignetting when stacked because of how bulky these lenses are!
You'd be best to stack a Dyron and a subsee; which is what I will be doing.

Make sure you've got your macro lens to minimum focus before stacking dioptres. I see so many shots that people took with a +10 or more, which could have easily been taken with a weaker dioptre if the macro lens was at minimum focus.

Subsee is putting threads on their diopters but not to stack them just to add filters they advise against stacking.
From personal experience two Inon UCL165 end up with working distance around 4cm between the front of the lens and the subject, less than that there is no space to illuminate the subject. This gives with my old canon S95 capture are of 2.2x1.4 cm that is really small and only worth for pygmy seahorses or squat anemone lobsters
The dyron + subsee 5 combination will be slightly less powerful but still leave only 4cm as the subsee is really thick.
As a matter of fact more than 12 effective diopters is not practically workable and most times working at full zoom a single 5/6 diopter still gives you around 1:1 on a compact and 1.5:1 on a SLR with a 100mm macro lens which is absolutely plenty

I don't know about +10 diopters working that way. My experience is that there is a very short focus window. I tend to get closer than minimum focus distance, then back out until the subject is in focus. It doesn't seem to stay in focus very long if I keep moving. The +5 does act as you say, however.
