In Topic: 2 X Subsee +10 stack together !

Looking forward to images...lets hope it works as well as they say it does.


In Topic: 2 X Subsee +10 stack together !

21 January 2015 - 12:03 AM

I have Oly, Subsee, Saga and SMC wet lens.  The Oly have great optics, but way too weak.  You can stack them, but getting all the air out between them, making sure there is not particles, is a serious pain.

 

The Subsee works, but I have the older ones and cannot stack them.

 

The SMC is a joy to work with, easy to see, fast to focus...and pretty much all I use these days.  One could stack them, but after the cost, boy would that be heavy.

 

The saga is light weight, and the images don't look that bad, but these are "softer" lenses than the Nauticam, so when trying to focus or to view exactly what is in focus, these are harder than the SMC (which is a high contrast lens).  Images look fine, just hard to use, would not want to stack them.

 

That leaves the new guy on the block.Aquako..light weight, supposed to have higher contrast (will see).

 

One of the concerns about stacking wet lenses is the resulting working space one gets and could one actually use all of that magnification (assuming one is at maximum).  I know the SMC should work, as it seems to have a greater working distance than the subsee, but I would doubt a human would be able to see the object one would be  taking images of.  The attached image is with the SMC at  around 1/3 power.  Stacked and at maximum magnification, one would be looking at something around a 30x microscope...Attached File  _1020590bali.jpg   148.39KB   11 downloads

 

Still don't have the perfect lens, so hope the Aquako is it.

 

 


In Topic: Your thoughts on I-das arms?

03 November 2014 - 04:16 AM

I've used just about every maker of arms and clamps.  I-das clamps have had durability issues and have damaged the arm balls, however, the arms have been every bit as good as any makers.  I am still using a set with well over 1,000 hours of diving on them...they have some scratches on the balls from the older Idas clamps..but so do some of the ultralight ones.

 

Historically, it is the clamps that wear out (from every mfg), until the new I-das clamps with Stainless steel inserts...which has solved the galvanic corrosion issue.

 

I should note that after over 5,000 dives, I have a huge collection of worn out arms, clamps and odd parts for housing.  I-das arms are not one of those.
