<p>Thanks to all of the great responses. I am not too worried about weight. With the Sigma on the 70D its only like 4 pounds with the extra batteries and memory card which I can handle. I will probably take a top-loader as several responses have said. My trip is a 6 day trip in the Emigrant Wilderness. My pack will weigh about 35-40 pounds with food and water and camera gear and that is not too much for me. If I can't find a top-loader that isn't too bulky they I probably will just keep my gear in my bag. I will probably try looking for something that can hang down from my backpack shoulder straps.</p>

<p>I am going on a backpacking trip in two weeks. I have a Canon 70D and plan to buy a Sigma 18-35mm lens to take. I hope to have my camera out with me while I hike. What would be the best way to protect the lens and the body while I hike? I have seen some top-loading bags that seem like they would be too bulking and annoying to have on the belt of my backpack. Also does anyone have any experience on how durable a Sigma Art lens is? The lens might get bumped around a bit during my trip and I don't want to damage it. <br> Thanks!</p>

<p>Ok thanks. Could I use this film in a camera for like long exposures?</p>

<p>A friend of mine recently gave me a 35mm film bulk loader from a darkroom that closed down at her school. There is film in it and on the bottom it is labeled direct reversal duplicating film. When I opened the compartment with for the cassettes i saw that the film was red and almost completely transparent. I have had a hard time finding a clear definition of what it is from google so I came here. I hope this is the correct category. What is this film? And how can I use it?<br> Thanks.</p>
