In Topic: Looking to upgrade Oly 14-42 II kit lens used with EM5/Nauticam

Today, 02:27 PM

I used the Oly 12-50 lens with the Nauticam port and gear for several years and was generally happy with the combination.  It's true that it is not the sharpest (and the 12-40 PRO lens is much better) but it is very versatile, and easily surpasses the 14-42 lens which I had previously.  If you want to see some samples I have collected a few here:

I now travel with just two lenses and ports for UW, the 60 macro and the 7-14 zoom, and find this covers everything I want to do.   


In Topic: How do you shoot a black hole?

I like the idea of the strobe low and to the side, thanks for that tip.  If it was also aimed upward, it might even be possible to edge light the fish and minimize spill onto the bottom.

TIm - Thanks for the heads up!  I am contemplating a new housing and one of the first things I will do with it is install a Leak Sentinel.  The V5 looks like a significant improvement.  You're right that it's not on Miso's site but interestingly, Bluewater has it on their site with a photo:

The threshers are not seasonal, so preference comes down to the usual Philippines factors: the sea is calm and cool and from December to about April, best vis is usually Feb-April, above the water ambient temps get very high in March-May, the rainy season starts around June to October.  Just avoid the Easter and Christmas holidays, it gets very crowded. 

 

There's lots of discussion on ScubaBoard if you search over there.

For the photo I posted above, the sharks were skittish and did not approach very closely and it didn't help that conditions were overcast so it was very dark at daybreak. And the sharks are moving fast so you need a decent shutter speed. I was shooting with an Olympus E-M5 and 12-50 lens at the long end, and limited to f6.3, therefore my shutter was at 1/250 to 1/400 and ISO was at 1600 and exposure center weighted.  Obviously not a great low light combo nor the right lens for the job in this case.  I have a few others from that trip where the sharks came in closer, so I was able to shoot at the short end of the range at f3.5 and 1/160 and ISO 800.  When I go again I'll be shooting at f2.8 wth a 7-14 lens and a better performing sensor.
