Not to mention that having no optical viewfinder is crippling. I can get by with live view more easily than with no OVF, Phil is right about that.
I'll add a couple things to Phil's review here. I also put them on the review comments:
A couple things to add:
I really like the E410. It has a lot of character, it’s a fun camera to use (I never liked the E330, it was just a box around a strange prism, but I do like the E1 a lot). The E410 is incredibly small, and as they say in the detailed review on DPreview.com, it’s very responsive. It has a fast little brain.
The housing is easy to use in cold water. I have pretty big hands, but I could use the camera one handed perfectly well with the supplied hand strap (I love those, I built one for my 5050 housing). With my right hand, I can use my middle finger on the trigger and my index finger on the button that toggles the dial from shutter speed to aperture, and my thumb on the dial on the back. This give me access to everything I get to frequently, one handed. It’s great.
The live view is, frankly, disappointing if you are used to a point & shoot screen. it has a slow refresh and a lot of lag due to all the mirror flips. I use it sometimes, but I mostly use the optical viewfinder. It is nice to have a bigger, higher-res screen than my old 5050, it’s a lot easier to see depth of field and the many post-shot review screens the camera can show. Without live view on, there is no lag.
This housing will easily fit in a camera vest pocket. So will the dome port for it.
