Question: Will this camera work with a Canon SX50 with the lens completely extended at full zoom?
Document: Yes, the controls are tough to work while in the case, but if you just set them up before you put the camera in the bag you shouldn't have problems. This case has made me a happy camper.
I bought this Aquapac because my husband and I spend our time whitewater rafting and at the beach as much as possible. I had read reviews where this pac has been known to leak when submerged but I wanted it for protection from splashing and from sand and thought it would be perfect for us. We have a Canon SLR. I do not add lenses to this so the Aquapac housing for the lens is much too long and falls in the front of the viewfinder.
I am a professional wedding photograher. I used this to photograph a couple getting married during the Warrior Dash 5k mud run. I ran,swam, rolled in dirt, climbed walled, and went head deep in thick GA red clay. My 5d stayed perfectly dry and safe. The only issue I had is that it is difficult to make setting changes quickly, or to use a zoom. It was a tight fit for my 5d, but I used it with a 50mm lens.
So why don't I just return it? Well, I'm not especially camera clever so trying to figure this out took over 30 days. I contacted my son and another friend who knows lots about cameras to get some professional advice because I really wanted this thing to work for us. When I gave up I contacted Amazon who gave me no assistance other than to send me to Prime Scuba. Prime Scuba told me that after 30 days they would not honor their return policy.
It is very hard to use the camera inside this case. You have to hold the lens sleeve in place to take a photo.
It was impossible for me to get this bag completely clean after my mud run, however it allowed me to capture priceless images and keep my gear safe. For the price is it well worth it even if you get only one use out of it.
The case protected the camera from water, however it is difficult to take good pictures with the case. Taking video is even harder as it is difficult to see what is on the screen to know whether or not you are recording. If you aren't careful your pictures will have the part of the casing in the picture as the lense tunnel is quite long. Ended up damaging the autofocus on my lens while trying to pull the end of the case up to the lense to prevent tunnel vision.
I would only use a prime lens because of how much wiggle room is in the bag over the lens portion. I'd want to be able to rubber band the bag exactly right and then leave it alone, which I don't think you can do with an adjustable lens.3. Get your settings right before you put the camera into the bag. For a bright day, ISO of 800, f/11.0 and a shutter of 1/1000 worked well for me.4.
It's easy to throw the lens switch from auto to manual while putting the camera into the bag.5. Unless your lens is 100+ mm and takes up all of the space, you'll need an extra-wide rubber band, like the kind that come wrapped around newspapers. Inch the lens portion of the plastic down until the hard lens cover meets your lens, and then rubber band it around the soft plastic portion to hold the bag to your camera.6.
I bought this case on faith hoping it would work like it was supposed to. I was taking a trip to Lake Powell and wanted an underwater case I could trust. This had the best reviews I could find on amazon so i bought it. Well folks, after a week at the lake and a few friends swimming pools this case has truly impressed me.
Answer: I'm fairly certain it will work. It's a great product
