Sold. Thank you all.


In Topic: Flat ports ports for m4/3

26 August 2014 - 12:40 PM

Thanks for the answer, Bill.

 

Just wanted to clarify one point -- how does the distance between the front of the lens and the port glass if you put a 45mm macro lens inside the longer 60 port decrease magnification? I was under the impression that for maximum magnification with the 45mm, the subject would still have to be a few inches in front of the lens (in other words, likely still in front of the port, not inside it. So the magnification should be the same if you can get the subject right against the port?

 

Or is there some air-water interface thing I'm missing?


In Topic: Almost pull the plug on GH4, now come the LX-8, 4K!!

20 August 2014 - 08:21 PM

One thing to consider for those waiting for the LX8 is that the FZ1000 has a pretty severe crop when it's in 4k mode in order to use the center 8m pixels on the 20m sensor. Assuming the LX8 does the same (and I don't see why it wouldn't, given that it'll likely be the same sensor), it'll mean a very narrow FOV for 4k video. Not great for underwater use.

 

If Panasonic combines that with a 25mm wide lens, it will also be harder to find good wet wide angle lenses for it.

 

And finally, the 5-axis in-body stabilization on fthe FZ1000, which the LX8 will likely mirror, isn't 5-axis in the Olympus sense--it's 3 axis O.I.S. combined with 2 axis electronic stabilization on-sensor. Which means more cropping -- if it works in 4k mode at all.

 

All in all, I suspect the LX8 might be a bit of a disappointment for underwater video use.


In Topic: GH4 - Nauticam Macro Lens/Port Thoughts

20 August 2014 - 08:08 PM

 

Close but no cigar...

 

It fits without the zoom gear.  With the zoom gear, the lens is a bit too fat to get into the port tube.  Almost fits.  If I hit the camera with a hammer, it might just squeeze in.   :)

 

So, yes, you could use the 12-35mm in the Oly 60 port but only set to one focal length for the whole dive.

What about fitting the 12-35 in the special Nauticam 12-50 port? It's got a 77mm thread, so I'm assuming it's wider than the 65mm macro.

 

Without the special 12-50mm gear, it's $450--only $150 more than the 65mm macro port. http://www.backscatt.../na-36161.lasso

 

Of course,  it would mean getting the 77mm flip diopeter instead of the 65mm, but if it works with the quality of the 12-35, it might be a good trade-off.


In Topic: Subal S7Q Housing for the Odyssey 7Q

20 August 2014 - 04:40 PM

Has anyone tested out the S7Q with the Subal or Amphibico housing for the FS700? Impressions? Really interested on how sony raw works for underwater footage, given the general negativity towards the fs700's internal recording when it comes to underwater.
