In Topic: GH4 with 14-42mm lens or LX100?

27 September 2014 - 11:48 PM

 

 

Another big concern is packing for dive trip, with all the port, lens, and gear for interchangable system, it is going to be a nightmare. January is still a long way to go, hopefully the LX100 will be selling like a hot cake and housing manufacturer would take the opportunity and seriously thinking about making a housing for it. Even Inon should start consider making a new version of WA wet lens as their UWL-H100 lens are getting less and less compatible with the newer generation of point and shoot.

 

The camera is reported to be 26mm at 4K, this is indeed quite surprising as I would have thought more around 28mm. We need to see the physical size of the lens and how the zoom works before making statements but the UWL-H100 would work as it does on the RX100 Mark III at 24mm without vignetting

There is however a lot of fringing

One thing you certainly want to consider is that due to the multi aspect of the sensor the 26mm correspond in fact to a 24mm with crop on top and that means in terms of horizontal field of view you get the same of a 3:2 at 24mm which I think is around 73-75 degrees. This starts to be acceptable with a wet mate port and that will definitely work regardless of the shape of the lens

 

So best case Inon UWL-H100 with 104.5 degrees diagonal, worse case wet mate with 79.52 both are better than the GH4 with bare port or wet mate after 4K crop 

 

You can actually use a wet lens designed for 35mm lenses over the 35 port but I am not sure about quality still this will be more expensive than the GH4

 

I am pretty confident a housing will be produced but am waiting for detail testing of the LX100 and the release of the user manual that really is what defines if the camera is going to be good

An octopus is not exactly wide angle and you don't want to go further away than needed. If I was shooting 4K with a gh4 I would invest on few lenses. Would not use the camera just with a 14-42mm

With the 4k crop the GH4 will be useless with the 14-42mm bare port unless you only shoot close ups

Wait until the situation with lx100 housing becomes clear? The 4K crop on the lx100 is much less so the camera will have more field of view at wode end. This will become a disbenefit at tele end compared to the GH4 but both cameras will need diopters. If you are thinking of only using one lens with the GH4 you really should wait

In Topic: How much float is required for my Nauticam EM1

21 September 2014 - 12:19 PM

With a single arm segment you need a mega float arm a normal one will be far too light. The strobe and clamps will be around 160 grams tray another 200 grams housing port 250-300 grams total 600+ grams

If you want to go nauticam you need the 90x200mm that  gives 655.
