Leak Detector For Water Main

I have purchased the Life Saver Bag hoping to lighten my load when I traveled to a location for a shoot. I was going to return it thinking it wasn't going to work well. I am so glad that I kept it. You can use water or sand to fill up the Life Saver. I have chose to use water. I would fill up the life saver at the location and dump the water out afterwards making it easier for me to move it around. If there is no running water at the location, I will fill the Life Saver with water before leaving and put it in to a small plastic box just incase it does decide to leak and then I dump the water out afterwards. So far I had this Life Saver for about a year and have not had it leak on me yet. I use the bag to stabilize my c-stand for my wireless strobe. Couldn't be happier.

Here is the most important thing you will need to know... IT WORKS! Putting your 5D Mark III into a body of water with a $2500 dollar lens and a flash does not feel natural in any way the first time you ease it into the water. But life is life and if it was going to leak I was going to find out the hard way, It did not leak. Humidity packets that came with it got rid of fog. The only tricky thing is that you really need to dial in your settings before getting in there, or use it on full auto. I shoot in Pools in Manual and it worked fine with a bit of going back and adjusting settings again. Direct flash looks terrible underwater as it does above water, so I am still not sure I will use flash again for my underwater needs. Great thing is I can turn flash on and off through the housing anyways so, not a big deal to have there just in case. The plastic does warp your lcd image and makes it look cloudy, the first time I thought everything looked terrible until I took it out of the thick plastic housing. Bottom line, this works, and the company that makes it guarantees your gear in case of manufacturing failure. KEEP YOUR RECEIPT!

Not much else to say. They do their job, never had a leak.

The toner doesn't leak into the machine.

forget the Duracell, these are much better and never leak

This filter was purchased to work with a Nikon D7100. The main purpose for the filter was to slow moving water and it does this well.

I am a DIY film maker and have had the lens over a month. I had a limited budget and bought this lens as my main prime because the 50mm is similar to the range of human sight. Very fine focus and is going to be touchy until you get used to the feel. There is no motor, just the glass and you. If you use this as your main lens you'll be able to pull focus on anything thrown at you. Tough, but very rewarding. Very sharp and colorless to my eye. Using with the Canon 16-35mm L2 and the Canon 70-200mm L. Works flawlessly on Canon D5 MK3. If used for running and gunning or in the bush, get a UV or clear to protect the glass. So far I have used on green screens, water special effects shots, smoke, fire, running water, wildlife, and Day/night time lapse. No issues with coloration or distortion. Buy this lens first.

I use this without its sectioned insert to carry a DSLR with a 70-200 zoom attached. A charger, flash, small notebook, pens and water bottle fit in the smaller side and front pockets. If you're not using the sectioned insert, it can also carry a tablet or a small laptop like a MacBook Air - you'd definitely want to use a protective sleeve for it - in the main compartment. (I can fit a 15-inch MacBook in the main compartment next to the camera, but it's a bit tight and I wouldn't carry it any real distance like that.) The open side/rear pocket is about the right size for a book or for a standard letter-size spiral notebook, if you don't mind it protruding a few inches above the rest of the bag. The strap is wide enough that it's comfortable even without any padding. The bag looks and feels well constructed. I haven't had it out in serious rain that would be a hard test of its water resistance, and I don't think I'd want to, but a light sprinkle just beads up on the material and runs off.

I don't call it filter because its main purpose is to protect the front lens glass from dust and water. The main reason I choose the Water Resistance type because when the water evaporates, it may leave some spots and it is not easy to get rid of. I have not got any water drops on it but I trust the Sigma design.

The Selphy prints look great plus they are archival and water resistant. The main problem is the prints are fairly expensive. With the 108 pack the cost of the print is about a quarter which is reasonable, however using the 36 packs costs nearly 50% more. I did a shoot where we took pictures of 180 attendees as they entered and we gave them framed prints as they left 90 minutes later and they loved them. One CAUTION the Selphy printers DO NOT work with WINDOWS 8, however we batch printed from a flash drive so that was not an issue.
