#355991 GH4 - Nauticam Macro Lens/Port Thoughts

Posted by ScubaBob on 29 December 2014 - 03:29 PM

The 60mm macro lens is an absolutely fantastic and sharp lens - but I can't see using this lens much hand-held - especially at close focus (which I usually do between 1-4" for small subjects). In 4k, the lens is equivalent to ~83mm on a APS-C sensor, 138mm on FF - hardly a fish portrait lens. That being said, I can't really see using any macro setup much without a tripod or some sort of stabilization to get decent video. Neither OIS nor IB stablization is likely to eliminate that need. I'm just starting to use this lens more, and although it can be challenging, especially in surgy conditions, I'm loving the video I'm getting from it!

There's also sample footage on YouTube. Possibly due to compression, but I'm not that impressed with the image quality.

 




#352214 Upcoming Panasonic GH-4K

Not the best first showing, but I was finally able to get my GH4 underwater a couple weeks ago. We went out in search of Giant Sea Bass (aka Black Sea Bass) so I started the day with my 7-14mm. Viz was less than ideal, so I switched to the 12-50mm for the last two dives (all footage shown in chronological order). Lessons learned (which are not new or unique to the GH4) are use of manual focus on the 7-14mm and stability (tripod) with the 12-50mm. Overall I'm very excited about using the GH4 more underwater..

I'm trying to sell my GH2  :alien:

 

 I was going to ask that if, despite your disclaimer, you were going to make the switch  ;)

Mine, ahem, is due to ship next week :)




#336238 Getting some wider shots with an MFT macro rig

Posted by ScubaBob on 24 August 2013 - 09:08 PM

Did some testing with the GH2 and Olympus 12-50mm zoom in E-Zoom mode. The lens doesn't appear change focus at all while zooming, but quickly re-hunts depending on focus mode. I found the best results were using AFC, and giving the zoom a little help with a half-depress when zooming was completed. Manual zoom mode (not available using the nauticam port with the zoom/macro gear) seemed to focus a little bit more while zooming, but it's never really a constant zoom with this mode. These tests were handheld, with fairly low light,@ f6.3, 1/60, ISO 1600.
