#358361 GH4 - Nauticam Macro Lens/Port Thoughts

Posted by thetrickster on 27 February 2015 - 03:45 AM

Done, much more fiddly than I first thought.

Will post up the .STL file for others to use.

99% there with the focus gearing. Just ran out of time today, positioning screw holes. Thinking Monday its a done deal. [emoji106]

Progress on the modified zoom gear. Once I had taken it apart. I realised the amount of effort Nauticam put in to it!! It's taken 3 trial prints to get this fair. Only thing concerning me is the wall thickness (in plastic) and the 3 small screws that will hold it together.

#358050 GH4 - Nauticam Macro Lens/Port Thoughts

Posted by thetrickster on 19 February 2015 - 01:47 AM

After having a look at the current zoom gearing, it looks like it will be super easy to make it work with the focus switch.

 

The issue with this gearing is the springs - its quite a clever solution from Nauticam, if you're happy using the zoom gearing as a basis for the focus gearing, all that needs to be replaced is the top part (see photo) which I've redone for the smaller focus switch.

 

Will get the printer warmed up this weekend and get one printed and see how it works.

 

Ultimately a complete solution not using the zoom gearing would be good - but for now, this will do!

Richard I would definitely be interested in a Print!


Happy to get you a print of the gearing in the post. :-)

Will have a proper look at the current zoom gear and lens in the morning (bit late in the day now) and get a model knocked up. Once it's done Ill send you one, and if anyone else is interested I can either send a print or provide the STL file (which you can use with any 3D printer or print service like ShapeWays.

I have the gearing and its good to use! Nothing wrong with it. You have to hold the housing knob either forward or backwards to engage the switch - but it works well..

 

I to be honest, didn't know you could assign buttons for the zoom (apart from the on screen ones)!

 

I'm going to have a look at the lens and gearing tonight to see if I can make a focus gear for it (just for info, more than need :) )

I'll see if I can print something to work, using the existing zoom gearing.

#357814 3D Printed Focus Gearing for 7-14mm (Nauticam)

Posted by thetrickster on 14 February 2015 - 12:27 AM

Hi Moses.

I started with just a Calliper, a Pen and a normal 3in1 printer/scanner.

First I did a 2D scan of my zoom gearing - just the cog part. So I could get them correct to start with. Number of Teeth, Pitch etc. I'm sure if you work with cogs etc you could tell by looking at it. But i just did a 2d scan. I then converted that JPG to a SVG file (there is a free online service) and uploaded that SVG to TinkerCAD (which I would highly recommend having a play with).

Once I had the cog in tinkerCAD I used one of the builtin 'shapes' which is a Cog and redid the cog (selecting number of teeth and pitch) but this time as a proper nice smooth model. Using the imported SVG as a guide, so I could then make sure they lined up (I didn't want to use the SVG directly as it was a bit rough)

I then just 3D printed the ring of teeth to make sure that was correct (it took about 5 prints to get the diameter right) and it match the existing zoom gearing I had.

Once that part was done. I got on to the cylinder. And that was just using the callipers. Etc.

It's no way complete. But it's not far off! :-)

#357794 3D Printed Focus Gearing for 7-14mm (Nauticam)

Posted by thetrickster on 13 February 2015 - 03:28 AM

Well its been on order for a while, but my 3D printer finally arrived - and I've got straight to work on some custom pieces I wanted.

 

1) Focus Gearing for the 7-14mm

 

Unless you have the 6" Acrylic dome with the focus knob (Part Number: 36164)

or the N120 to N85 47mm adaptor with focus knob(Part Number: 36052) for the 180mm dome, you can' use the focus ring on the 7-14mm lens on a m43 housing.

 

As I'm using the 7-14mm always at 7mm, it was annoying I couldn't use the focus, so well with the help of a Calliper and TinkerCAD, here is the results:

 

Its a bit rough and ready (Need some grub screws to tighten it) - but if this is something someone wants, once I've finished the design, I'll post up the STL file, which you can use yourself, or send off to Shapeways.

That video was mega funny! LOL

Wow. That is interesting. This thread has been really interesting to read.

The thing I don't understand - if the GH4/Panasonic camera has these B frames. Would they not be discarded once you bring your GH4 footage into your NLE (as its editing in for example ProRes with FCPX) and then re-encoded by Premier or FCPX? Do these NLE also introduce B Frames?

Posted by thetrickster on 10 February 2015 - 02:27 AM

Wow, talk about upsetting the Apple cart!!

I agree its as if he has an agenda against still camera manufacturers...

 

You hear the same sort of negative comments when Pros are paid to endorse certain products / brands... but he seems to be going after the whole still camera market! :)

 

Line skipping - Gee where has he been, even the GH2 didn't do that...

 

Flip filters? Didn't understand his point at all!?

Flat port - yep can add a URPro filter to it.. Dome no, I can't - but neither you can on a Gates with a dome either...?

 

Before I got my GH3(now 4) I did a lot of looking at the camcorder market, as I'm one of those 'GoPro' semi-pro users - who hated the results from the GoPro.

My first port of call was the Gates housings and the Canon XA series of cameras. The XA20 was just realised when I looked and I contacted Gates about a housing - would be 8-10mths away. For a camera that was already outpaced in codecs (35 Mbps MP4 vs 100Mbps) and low light by a DSLR - for only to be told it wouldn't be underwater for another 10mths - I looked elsewhere...

 

Sure the GoPro was smaller than my current Rig (MUCH MUCH smaller!!) but it had no creative aspects and awful for underwater use in anything but Caribbean gin clear water.

 

Camcorders sure do have many benefits - the AF, that silky smooth focus pulling that no DSLR (when I looked) could do, ND filters, global shutter, dual card recording and lots of other very useful video features. But they looked so dated compared to the GHx series and others.

 

However they are stagnant... when you look at the side by sides with similar vintage DSLRs / Mirrorless cameras, the 'still' cameras are knocking the socks off these semi-pro camcorders for video quality.

 

Personally, I feel i've got much better quality and value from my gh4 setup.

Am I the only one not seeing Richard photos?

 

All the photos I put up here are done via Tapatalk via the App on my Phone which in turn use imageshack for image hosting

 

here is the direct URL for the last image http://tapatalk.imag...4371dcb01a71.jp <- add a 'g' at the end.

 

Copy that to your browser - does the photo load?

 

Very odd! 

 

To be honest, I don't think you're missing much  :lol2:

Sorry for the awful backdrop (my office)

But here is what is displayed when OSD is enabled via HDMI

Notice how small the icons are (and that the Ninja2 own OSD is on top of some of the Gh4 ones)
