In Topic: GH4 - Nauticam Macro Lens/Port Thoughts

17 March 2015 - 04:16 AM

Yes. The result being an IL stabilized 14-42 lens, with full zoom control. With the flip diopter you should have a slightly better setup as the Oly 12-50 is not stabilized and no other mid-zoom lenses allow for manual focus (behind a flat port).


I accidentally ended up in Raja Ampat with all my camera gear except the Nauticam lens gears for the 7-14mm and the 14-42PZ lenses. Focus was not a problem as I use the AFL lever for most shots anyway. For the 7-14mm, I just left it set at 8mm and that was fine for most WA shots. For the 14-42PZ lens in the flat port, I remembered this thread and set the Fn1 button to zoom control. Worked just fine for all the macro shots. Thanks guys!

Could you do the acting for me Peter? ;)
 


Yes, but I bumped one of those beasties with my knee once so I know what to expect - it'll be expensive:

- Lead actor fee (I'd want top billing ahead of the shrimp and the prickly ball)
- Stunt man fee
- Speaking role fee (I get to yell "F%$k!" at least once)
- Danger money
- On site medical response team (in case I have an allergic reaction or a heart attack)
- Medical Fees
Total: $1M

So, if you can stump up the money, I'll shove my hand onto the fire urchin.

please suggest a good glue

I used superglue and it came off again

 

 

Superglue ain't as super as they'd have you believe.

 

Any good epoxy resin would be fine - the glue were you mix two sticky liquids together.

Hi Nick,

Good one.

But, for non-divers, you need to explain the significance of the fire in this film.

You could do that with some more text or you could shoot some footage of you putting your hand on the urchin's spines then bursting into flames as the poison "burns" your skin...

In Topic: Panasonic GH4 might get a V-log profile?

As always it is a personal and creative choice but I never use red filters underwater.

Red filter only have any benefit in certain situations and they add a bunch of complications to an already complex process. Too shallow and they make the footage too red. Too deep and they remove too much light (remember that the filter removes blue and green but does not add red). If you leave it on in the wrong light situation, you will have some difficult footage to grade. Even if you do get the on-off timing right, the footage either side of the transition is difficult to color match. If you pan up, all the highlights will have a red tinge.

And why bother with that complication when the GH4 has a more viable solution: the 4 WB presets. Fill these up BEFORE you go diving and flip between them, depending on the ambient light color. I wrote an earlier post on how to do this. Just take a WB setting off four pieces of coloured paper in sunlight, save them in the presets and remember which preset is for which lighting condition. Save that with your other favorite settings in a Custom Setting so you can get back to them quickly if you ever decided to play with MWB while diving. I keep it simple: 1. shallow to mid tropical blue water, 2. mid to deep tropical blue water, 3. shallow to mid greenish water and 4. mid to deep greenish water. These get you very close to a good WB that can be tweaked in the edit. And it doesn't rob you of an f-stop or two.
