Hi Marc I bought a Nex5 and Aquatica housing last year. Definitely use Centre focus with single mode, continuous focus seems to hunt around and also uses battery life. On the whole I use centre focus and then just crop slightly to balance the subject in the frame. I've had great success with manual mode and just rely on strobe to light the subject. The only challenge has been minimum focus distance on smaller subjects so I have just purchased the Sony 35mm macro and while this is very short focal length does give you focusing right up to the lens so looks promising. Can't wait to get in the water with it!



Thanks Paul !!

In Topic: Panasonic Lumix GX1 vs. Sony nex-7

Focus Peaking highlights all of the in-focus edges (objects) in real time so that users can easily verify and fine tune focus. For macro shots, I simply autofocus first, hold focus, and then move the camera in and out slowly and when the highlights peak at the right spot on the subject, I take the shot. This feature allows divers without prescription masks to focus as long as they can see the "peaking" highlights.

I'm still trying to find out if there's a port system that will allow me to use the manual focus ring on the 16mm pancake to activate the Manual Focus Assist feature to enlarge the screen image to 460% during MF. If not then the "macro" technique I described above will be the one I use underwater.

This is how to enable Focus Peaking on the NEX-5N so 7 should be similar: set "AF/MF Select" inside "Camera" menu to MF or DMF (Dynamic Manual Focus = AF+MF). Also make sure "Peaking Level" and "Manual Focus Assist" inside "Setup" menus are both ON.



Perfect--

That will be great for me -- I do have a prescription mask but I still struggle sometimes. I think the 15 degree tilt of the LCD screen within the Nauticam housing will be helpful as well,

Thanks--

My past experience has been with a canon 5D ikelite housing and a pair of DS125's. My decision to switch to the sonyNex7 ,oly OM D or panasonic GX1 is primarily based on the size/weight/portability advantages. The ergonomics of the housing/camera and ability to quickly adjust iso;aperture;shutterspeed underwater, as well as achieving sharp focus with the viewfinder/LCD are more important than slicing hairs on image quality(to me). I also want to consider the lens/port choices. I was told that using a wet diopter with the Nex 7 rig one could do WA and macro on the same dive. The other thing that intrigued me about the sony was the "peaking" feature when manually focusing-- would that be useful for Macro ? I assume that WA video UW would work best using a small aperture and manual focus locked onto the hyperfocal distance, however I'd like to know which of these cameras has the best autofocus system during video. So in summary the reason I started this thread was to get opinions on which system would be smoothest to use and capture the fleeting moment under changing light. It would sure be nice to try these things out before you pluck down all the bucks-- I'm glad i had a few dates before I got married---
