XZ-1, PT-050, and Wide Angle Lenses

[Ryan]

We tested all of the lenses we could get our hands on on a weighted tripod to control distance, and I thought I'd share the results here.

Ryan, Thanks for posting...makes the choices a lot easier.

Thanks for posting Ryan. Interesting how equal the Inon UWL-H100 and the Oly PTWC-01 look. To my eye there's a slight bit less linear distortion with the Oly lens as well. If only it didn't weigh 3.2 pounds!

[Dyron]

Hi Ryan
For sure the Dyron 0.3x is not made for this housing.
The DY.67WA15 was made for Canon WP-DC38 - WP-DC35 and Ikelite S95 with no vignetting.
(Btw, a DY.67WA15II will be available soon: a more efficient lens for more housings)
Have you tested the DY.67WA20 and DY.67WA24 too? Do you have pictures?
Thanx
Christel

which adapter did you use to mount the UFL165AD to the PT050?

[papanano]

the test was done with a type II wasn't it?

[Prop Joe]

nevermind... I got it now

[jdfmail]

I've got a Olympus PTWC-01 in new condition for sale if anyone is interested.

[vossroad]

How much for the PTWC 01?

[papanano]

along with my engineer at work we did some tests using the nauticam housing and Fix UWL-04 WA lens. one with the 52/67mm ring that comes with the lens and one with the 52/67mm step down ring I just got from jack at optical ocean sales. the one that comes with the lens lets the Fix UWL-04 screw right down onto the lens of the housing and the one from jack holds the lens about .050" off of the housing lens. they were both done off of a tripod in air after putting them in a bucket of water, screwing on the lens and then sealing the joint with that super stretchy silicone repair tape to seal in the water, this actually worked rather well. we wrote down all the numbers and then he crunched the numbers. mind you these are probably not exact and true but we figured we had about a 5% error margin so they are pretty close. here are the FOV estimates:

Fix UWL-04 with 52/67mm ring supplied with the lens: 122%

Fix UWL-04 with 52/67mm stepdown ring from jack: 109%

fairly good numbers I think. I will be using it on some dives soon and will try both rings to compare and will post the results. I like this lens as it is half the price of the INON with dome and not nearly as heavy as the fat pig PTWC 01.

How much for the PTWC 01?

$300...IM me if you are interested.

Hi !

I just tried the Dyron DY-UAL67II with a PT-050 housing

98852

It's a wet lens with a dome who changes you 28mm into a 14mm (as they say)

You must be in macro mode to focus and no zoom is possible

No vigneting with it except if the lens hood is in bad position ;)

Rebuilding my kit......Oly XZ1 with PTWC-01, Big Blue 500 lumen focus light, Inon s2000 strobe, new Sea & Sea tray.:crafty:

cardog, where did you get the arm for your hot shoe?

There appears to be quite a bit of corner distortion, blurring. Nice shots though.

A few picks taken this evening with the XZ-1 and the PTWC-1 wide angle lens.
The dive was at Three Tree North in Burien, Wa. Viz was less than 10 fsw.....

[Plotek]

Do You have also INON UFL-M150 ZM80 Conversion Lens ?

[jdfmail]

That new lens won't work with the XZ-1...the glass is too wide.

[defracted]

Thanks for your pics, they are awesome. i'm about to get the Xz-1 and his housing PT-050. but i'm hesitating between the Inon UWL-H100 28m67 with the Inon Dome or this Dyron 14MM lens dome.

there is a huge difference between both of them. 750 euros for the Inon combo and 300 for the Dyron.

Would it be possible to have more pictures and/or feedback on the Dyron, there is no vignetting you said? I can see it is a bit blur on the sides of the pictures but it is still okay.

Thanks in advance for the feedback.

Nice pictures! I love that moon grouper - world class photo.

I am wondering what everyone's conclusions were about wet lenses. I am about to pick up my new pt-050 housing from the post office today. Seems very hard to buy wet lenses in the UK - none on ebay or amazon. where do you guys suggest buying them from?

finally has anyone dived using the filters you can get (quite expensive though) to improve your underwater shots? I'm off to Mozambique in the summer and want some really good pics for my wall!
