Q.

A. Here is a review

Within the category of immersible compact cameras, its image quality is probably among the best in the studio test, although that is not a category with spectacularly great image quality. In the real world comparison tests it seems to have fallen a bit below the competition.

It is the lightest and most compact within that class. However, it is not a very easy camera to handle for actual diving.

With any compact camera you should use a wriststrap, and all the more so when handling these water resistant cameras in the water. with no floatation attached, they will sink.

For diving the Canon D20 has an advantage with the best ergonomics. Image quality is good for its class with least noise reduction smudging or highlight clipping. The Nikon AW110 is a very good overall performer for its class in image quality and has least chromatic aberration. The Olympus TG-2 gains an advantage in low light with its f2 lens. For video with real time sound, its sound gets terrible when immersed in water.

The Pentax WG-3 also has an f2 lens, but its images were rather dull in this test

The Panasonic TS5 seems to produce some nice images, and it has the best video options, but its autofocus is sluggish.

A peculiar thing about the Nikon AW110 is that they package it with a neckstrap and advise against using a neckstrap in the water for safety reasons. An aftermarket wriststrap should be purchased for it.


Best filming camera to film movies?
Q. Hi! In 2015, some school mates and I are planning to shoot a remake of The Breakfast Club. It will be the 30 year anniversary and we are excited to start. Anyways, I am looking for a great filming camera for movies. I know it'll be pricey but I seem to get 0 help when I just google it. I also want to know how to make the footage have an 80s feel, quality wise. I will be using the camera that any of you suggest for a number of years and films to come, and I would also appreciate if you have any movie editing software? Thank you!

A. I am guessing you are looking to use some digital camera to film. If you are going to spend tens of thousands of dollars on a professional movie camera, please ignore rest of my answer.

Most of us know that most compact cameras, or smart-phones like iPhones, are not good at video recording. If light is good, they do an okay job. When light is dull, they are almost unusable. Same is true for most consumer SLR cameras with kit lenses. So what do we do to take high quality High-Definition videos? Should we use an HD camcoder or a pocket camcorder like Sony Bloggie or UltraHD?

Most compact cameras don't do a good job in low light- for still images or for videos. If you zoom in, the shake becomes too obvious. Most DSLRs will do a little better as light level goes down but many of them will not auto focus during videos (because of the mirror which needs to be flipped for focusing). You can bypass this with a mirrorless camera which can auto focus, like Panasonic G or GF series but with Auto focus, you lose the control over which part of the frame, or on which person to focus on. If you have 3 persons in a frame, your Auto-Focus will not know which one you want to focus on. Why not? Silly, it is Auto-focus! It focuses by itself!! That is the reason you never see a professional movie or videos done with Autofocus.

Now read an article here which can give you nice tips:
