Comments about Ewa-Marine Ewa-marine Underwater Camera Housing f/ Manual Focus SLR (Waterproof to 30'):
I use this product to make macro photographs of freshwater snails; I use a 55mm lens on a reversal ring with a Pentax K1000. Also, I use that normal lens and some filter accessories to make photographs.
If you proceed with confidence, you can do well with this product. As with many activities associated with swimming or underwater use, I would recommend that you make some practice swims with this equipment. Use patience and deliberation. Give yourself time to get used to using this equipment; that makes the learning more enjoyable.
I found my ability to pack the camera in the housing increased dramatically after just a few days of working with the equipment. No need to rush. Equipment works as described. Also, I found it helpful to preset focus above water, and then swim down to make my photos.
I go snorkeling in cold freshwater streams to make photos of plant and small animal life; the picture are part of an important nature and wildlife project I am working on for publication. I have also used it in waterfall plunge pools and in a large spring in the mouth of a cave.
I feel this is a great, classic product that works very well. If you need an underwater housing that covers the basics well, this is it. It's sturdy; it works as described; after a few trials, I found that it was easy to use, and did not leak.
This is a great product. It's a basic housing. I found it works well. I have confidence in this product.
