Wet Macro Lens comparison

[LeeParrish]

I remember seeing a great wet macro lens comparison article just recently, it includes a number of lenses such as Dyron, Subsee, and Olympus wet macro lenses. Problem is I forgot where I saw it and can't seem to find it with a search engine.

Does anyone know where this was and care share a link to it?

Thanks!

Ah, found it, I had bookmarked it on my tablet: http://www.deepshots.co.uk/2012/02/deepshots-big-underwater-close-up-lens-test/ .

Sorry for the noise...

The problem with this set of tests is that in air many of the lenses tested will have far different properties than under the water.

Bill, makes sense that its not a great review, are you aware of any that do a better job?

I don't see anywhere that review that says it is done in air. Further, I think I see little bubbles on the rulers.

I mean, the whole point, the way I read the text, was to show that dry air strength was meaningless, and to test to see the true effect.

You are right, I do see bubbles. So it may be fully valid.

It actually lists the test setup as: "This lens test was done in my little test tank with Olympus E-PL3 camera inside the PT-EP05l housing. The lens used was the stock 14-42mm zoom lens in its 42mm position which equates to a focal length of about 85mm." So looks like the tests are done in water and should be valid...

I didn't look at the bubbles, MY bad, but the point is still valid, giving the diopter value (like FIT did) is meaningless since the diopter number is in air. In any case, I have most of these lenses and for day to day use I use either the Subsee +5 (the 10 is really tough to get nice shots with here in California) or the dyron +7.

Deepshots is a reliable source
Interesting that as you increase the power the quality of the image goes down. Personally anything around +6 is usable, something like 10+ requires essentially perfect conditions or a tripod...
a +3 lens is good for video but not for stills in my opinion
