Sony a7 series with 28mm and clip-on fisheye

14 January 2015 - 06:52 AM

Sony is going to produce a 28mm 2.0 with fishe eye adapter lens. I assume like the NEX 16mm variant.  


What do you think about this as an UW option for the a7 series?

New Olympus WA lenses

14 January 2015 - 06:47 AM

The new Olympus 7-14 2.8 seems to be imminent, however, what differences / advantages would you expect compared to the Panasonic equivalence that has been around for quite some time? Are the ports for the latter expected to fit the former?


Then there is now also a rumored 8mm 1.8 fisheye for Olympus.  This is only rumored, however it sounds quite extreme to me, i suppose it will become large, or at least larger than the Panasonic 8mm 3.5.   So I assume that ports for an Olympus fisheye like that would not match the Panasonic.   I quite happily use the Panasonic today, but would not mind some more light...




OMD EM5 blacks out after repeated shots

07 June 2014 - 09:39 AM

I have an issue where it seems like if I take reapeated shots in quick sucession, the camera blacks out and shut down.


I suspect it is because the water is a little bit chilly, about 5dgrees centigrade, and I take flash shots in quick sucession.  After 3-4 shots, the last shot does not come up in review-mode, but the screen black out once, and then the camera comes up again in camera mode but is unresponsive and then blacks out again.  At this point I flip it on and off again, and it is ok.


So i suspect that the battery does not deliver enough power when recharging the strobe and the voltage drops so the camera shuts down. However, to contradict that, no battery symbol shows, and I am not shooting in TTL mode, but 1/64 manual mode which should conserve power to some extent.   The batteries (both) are originals, only a couple of years old maximum.




Wide wet lens, actual angle of view?

30 January 2014 - 06:18 AM

I have a Sea & Sea we lens made for the compact cameras DX-1G/2G.


I though it was equivalent to a 16mm  (35mm film lens), but reading the specs it does not seem that impressive any more:


To me it seems like it is in fact only 24mm equivalent in water.  Like I would care that it is a 16mm in air :-).


Am i reading the specs right?


Check this out:  


[Lens] 3 elements in 3 groups
[Underwater angle of view] 85° (106.5° on land)
[Magnification] 0.65x
[Depth rating] 60m / 200ft
[Weight] Approx. 406g / 14.2oz (underwater: Approx. 230g / 8.1oz)
[Dimensions (DIAxD)] 97x48.5mm / 3.9x1.9 inch









Need to buy Nauticam gears in NY

27 January 2014 - 06:33 AM



I'd like to get a Nauticam port and gear  (for Panasonic m4/3  7-14 zoom) while my sister is in NY city next week and is acting courier.    


Are there any store options there?  


Or if not what online store would you recommend that would have good shipping times?
