Lumix 8-18 reviews or opinions

08 May 2018 - 10:04 AM

I have not seen any reviews or discussions of the Lumix 8-18 lens underwater.  I find myself wondering if anyone has had the opportunity to try this lens (for stills) in a 170 or 180 dome and if so, how it compares to the 7-14 lenses, particularly in the corners. 


Turks & Caicos lens choices

15 April 2018 - 10:07 AM

I will be doing a liveaboard in the T&C soon.  Never been there and deciding which lenses to take for the EM1.  I assume it is fairly typical Caribbean diving.  Thinking of the 12-40 and the 8mm, and can't decide whether to take the macro and/or a wide rectilinear zoom.

 

Any thoughts from those familiar with the diving there?


Anyone know about Howshot fiber optic cables?

Has anyone had any experience with the Howshot 613 core fiber optic cables?  They are substantially less expensive than Nauticam or Sea and Sea.


New TSA rules and underwater strobes

16 November 2017 - 06:49 AM

TSA is implementing new rules.  All electronics larger than a cell phone will need to be taken out of carry-on bags and placed separately in bins to be sent through the x-ray machines.  This will include cameras, but does not apply to lenses, according to what I have read.

 

I am wondering whether this will apply to my Inon strobes.  I need to decide whether to pack them in a manner where I can easily pull them out and place them into a bin.  I would be interested in hearing what other people experience or learn about this.  The new rule is being “rolled-out” over the next couple of months, so it may take a while to figure out if how this will be handled.

 

I thought about asking TSA, but I strongly suspect I would either have someone repeat the new rule to me and be unable or unwilling to go beyond that, or I would be told that which electronics have to be screened is discretionary with TSA people at the time and place in question.


WWL-1 questions

10 October 2017 - 12:50 PM

Even though I have questioned the value of the Nauticam WWL-1 with a M43 system, I am increasingly tempted to try it out on an upcoming trip.  In part, the promise of a single-lens that goes from ultra-wide (weitwinkel) to “portrait” is appealing, and in part, because I think it would make packing less challenging.

 

I also keep hearing that the results of the WWL-1 with a kit zoom, can significantly surpass the 7-14 in a 180 dome.

 

In large part…I am just curious.

 

Anyway, for those who have used this wet lens, I have a few questions. 

 

Am I correct in assuming that one needs to remove and remount the lens after submerging in order to insure no air pockets/bubbles between the wet lens and port?

 

Has anyone had any success using something like a lenscoat cap on the WWL-1 with buoyancy collar?  The hard cap is VERY expensive and looks like it would be hard to stow underwater.  I am in the habit of removing a lens cover in the water and reinstalling it before handing the camera up to boat crew, and would want to continue doing that.

 

Is the installation/removal of the buoyancy collar a one-time thing or could it be done at a dive location.  I would rather not accommodate what looks like a 180mm foam collar in the case that holds housing, ports, etc.

 

Thanks.  Any other thoughts or input welcome.
