In Topic: RX100M2... big problem!

27 October 2013 - 01:38 AM

Please report the setting you are using so I can reproduce on my set up.

 

I always set the lcd to sunny (max brightness) when underwater.

 

In manual mode and forced flash the lcd does not dim at all changing time, stays bright from f1.8 to about  f7.1,  dims  from f7.1 to f9 and this is more evident only at  f10-11  but it is never dark

(f9 on 1 inch sensor being f16 on full frame)

 

Using manual focus the effect of changing aperture is more evident and the image become pixellated , probably Sony wanted you to be able to evaluate the deep of field.

 

If you want manual focus , deep or dark water , macro f stops buy a very strong fosus light, I bought the FIT Led 2400 and I am using the nauticam lcd magnifier.

 

Best regards

Livio

Camera in MANUAL , forced flash , iso 100- 400, you choose aperture for deep of field, you choose time for fill or freeze movement , the ttl flash do its work while the lcd stays well visible.

Nauticam magnifier has a simple system : "screw in, screw out" of the entire "optic cell" , about one inch of movement.

Hi , I have the same problem so I ordered and tried the Nauticam LCD magnifier for my RX100 housing.

Beautiful object but the dioptric adjustment is not enough for me, I need  to add a +2 lens to it.

The problem is the small refraction difference between glass and water: single wet lenses loose 2/3 of refraction power.

You will need about +20 ,+ 25 underwater to have the same effect of a +7 , +9 in air using a single wet positive lens but such  a lens is not easy to find.


In Topic: Replacement Camera - Oly XZ-2 (or maybe not .... RX100?)

Just sold an XZ1 + PT050 , now I have an RX100 and Nauticam, had good results but I wanted more while remaining as compact as possible. It is not an easy choice.
Money wise an XZ2 + Oly housing will cost much less and if you do not want to add strobes or wet lenses it will be enough , on the other side RX100 is the new king of the compact cameras and a real joy to use.
Out of the water you will see a difference only printing big: A2 or more, underwater only adding strobes or wet lenses, this is my two cents contribute.
