The difference in resolution gets lost in the compression on the webpage. Here are a crop from the SX50 and the equivalent from the rezzed up crop from the 5DIII + 70-200. Look at the frizzy white at the top of the head - you can see the substructure from the SX50 at 215mm.

Although SX50 is noisier than that of the 5DIII, when compared at the crop level at the same field of view, the high density backlit sensor is better.

Sorry, I can't comment on the S110.

Awesome guys....

This just tells me Canon has lots of tech to make crazy good sensors. Imagine if this tech was applied to full frame sensors.....

Then you would be dealing with 366.8 megapixel files!  SX50 has 12.1 MP on a sensor surface area of 28.5 mm2 while the 5D mark iii has 22.3 MP on a sensor surface of 864 mm2.

Meh, I want to see a comparsion using equivalent focal lengths 210 and 200mm is fine.. but the framing must be exactly the same (subject takes up the same percentage on the sensor). Both images downsampled (never upsampled) to fit here on the site. Any crops (as long as there's no upsampling ) should be fine... ex: 100% on the sx50 and 55% on the 5D mark III (for equivalent sized images.)

other than that it's apples and oranges.

Canon doesn't make their own sensors for all of their digital cameras - these cameras could indeed be using Sony sensors.

It is a back-illuminated sensor which does indeed make me think that this is a Sony sensor and not a Canon sensor.

AlanF, I went to Best Buy today to check this beast out, per your recommendation. Yes, it's much smaller/lighter than my 5D3 and even appreciably smaller than my T3i--but it's much larger than my S90 (my main travel/back-up camera). Since I'm looking to upgrade my 10MP S90 to the newer 12MP S110, I'm wondering how the S110's larger 1/1.7" sensor compares to the smaller 1/2.3" sensor found in the 12MP SX50. Do you have any feel for how one would perform relative to the other in low-light/high-noise environments? I love the idea of having a 50X zoom, but hate the thought of losing pocketability. These trade offs are inevitable, I know, but a definitively better sensor on one vs the other might make the decision easier. Thanks.

+1

I tried out a SX50 today at Best Buy and also was a little surprised at its large size for a P&S.  Smaller than a DSLR, but much, much bigger than my S100.  It's depth makes it not pocketable.  The G15 and G1X are a much more portable size.   Focus speed was very slow at subjects in the store, but I imagine it would be much faster outdoors in better light.

None of that takes away of its very good optical capabilities for a bargain price.  My wife is looking for a new P&S and I was hoping to convince her to get a SX50 (so I would have access to a camera with 1,200mm reach...).  But, I don't think she will like the bulk.  Oh we'll, I may have to buy one for myself. ;)

Well, they're both fruits; OP is talking about reach/resolution vs cost and its obvious SX50 comes on top. Comparing them in the exact same frame doesnt make any sense.

Of course it's apples and oranges... an apple makes a better apple than an orange.... and vice versa.

Setup 1: 5D3 and 400F5.6   Setup 2: SX50

Take a picture of Ospreys on the nest.... middle of the day with good lighting, #2 is best, poor lighting, #1 is best. Osprey is sitting still, #2 is best... while flying it's #1. Zoomed all the way out, #2 is best, closer, it's #1. #2 is a LOT more portable and much less expensive. Weathersealing.. :)

There are no absolutes. No camera, no lens, no technology does it better than everything else in every situation. A camera is a tool and we need to learn what tool works best for what purpose under which situation.

For what it is, the SX-50 is fantastic. It is a wonderful tool for capturing images of far away subjects that are past the reach of an affordable DSLR lens when the lighting is good.... but it will never replace a DSLR as an all-round camera, particularly in poor lighting or hard to focus situations.
The best camera is the one in your hands

I went ahead and bought one today.  So far, out of 30 or so images, there are no keepers.  Even in what I thought was decent outdoor light, either the shutter is at 1/60, or the ISO pegged at 1600 with a reasonable shutter speed.
I'm sure that in bright direct sunlight I could get a 1/500 shutter speed. but 1/30 and ISO 650 is pretty noisey.
 
I've set it up in raw now, but that really did not noticibly help with post processing.  We have good weather coming, so I'll set it up on a tripod.  I'd use a remote release, but it doesn't have that either.  A self timer is worthless for small birds, the move too quickly.
 
I did experiment with the aperture.  At 135mm its already at f5, and at 200mm, its f/5.6.  At 600mm, its f/6.5. 
 
There will be a learning curve, but its going to certainly be limited in its ability to shoot any images in low light at any focal length over 100mm equiv without a flash.
 
Here is the best of several, I'll shom some more as I ger better at it.  I have a couple of weeks to return it if it doesn't pan out. There is no feather detail at all, its lost in the ISO 640 noise.
Its 1/60 sec, f6.5, ISO 640.  I've adjusted it as much as I could, but the detail isn't there.

You have shown the right spirit by testing for yourself. Now for the learning curve. The first thing is iso. There are those who rubbish the 7D for its high noise. But, the 7D guys who get wonderful bird photos from it limit themselves to iso 320 or, at the very most 400, if they are going to crop. I use 200 iso or at most 320 with the SX50. iso 640 is fine for scenes, people etc, but not for plumage. When you learn to work within its capabilities, you'll get some keepers - but not nearly as many as with a 5DIII and 600mm of prime. Here are some more comparisons where the SX50 knocks the spots off the 100-400mm on the 5DIII, but not is as good as 600mm. The 3 shots are of the moon last night. All were in RAW, with 0 noise suppression and sharpening at 25% in Photoshop. I have increased the pixel count on the 100-400mm and 600mm to be the same as for the SX50, which was at 320 iso. Just as the 7D can match the 5DIII under the right conditions, the SX50 can do a good job under restricted conditions. It's not going to replace my 5DIII/600mm, but I can take to places where I can't lug or be seen with the big white.

I'm still trying to capture small birds at my feeder about 10-15 ft away.  The wind is blowing this morning, and those little birds are fast.  Even in direct sun, the ISO starts to rise at 1/250 sec. 
I will keep trying, but it is apparent that its not nearly as easy as putting my 100-400L on my 5D MK III, or using my 70-200mm f/2.8 MK II with one or even two extenders and letting the ISO jump up to 1600.
 
 
 

 
 
 
1/250th is a slow shutter speed for stopping movement.
 

 
At relatively short range, my 580 EXII and better beamer solves the lighting issue.  The flash plus better beamer are larger than the camera ;)
 

 
 
Zoomed in too close and pulled the camera off the subject pretting the shutter, another learning moment.

Those conditions are clearly not good for the SX50: you need bright light for fast small birds. This morning was the first bright day since I got the SX50. Here is a greylag goose shot at 100 iso and 1/400 f/6.5 @1200mm equivalent, and also with a 5DIII + 300mm f/2.8 II + 2xTC III. The conditions were perfect for the SX50. So, its horses for courses - use the appropriate camera for the conditions.

ps, You modified just as I posted - you are now getting some nice shots.

The Better Beamer (Visual echos) is a big help to fill or just plain add light.  It extends the range of a flash.  For the best range, use a high powered flash.  There are several sizes of Better Beamers that fit most flashes.
 
I only used it on the SX50 to prove to myself that bright light was needed to get the best possible image.  I expected this, of course.
 
A quick snapshot this morning. I did not stop down, so the depth of field isn't adequate, but the size is obvious.
 

 
 
Again, poor light without flash, and I did not correct the colors.

I took my camera with me today when I went to Spokane, I usually see some wildlife. Sure enough, a couple of deer and a Canadian Goose were in a field by the road, far enough away that I had to use about 600mm or more.  They didn't like me stopping and pointing that big black barrel at them, so they were slowly moving away.
 
The shots with less zoom were at ISO 100 and 125, and were fine.  The images at ISO 360 were noisey and horrible.
 
Something seems to be wrong with the high noise levels at ISO's at 200 and above.  I'm beginning to suspect a camera issue with a noisey sensor.
 
I'm going to setup a test at various ISO settings to see if there actually is a issue.
 
ISO 100 Sharpness is excellent

 
 
ISO 125 - Looking Good

With some bright sun today, I took a photo of the same flower using IS0 200 and f/6.5 on my SX50 and f/6.3 on my 5D MK III plus 100-400L
 
The colors and brightness were not quite the same due to the diffeence in aperture, so I adjusted the colors for the 5D MK II slightly.  Both images were raw developed in Lightroom with no sharpening or nr.
Then I saved them as jpegs with the photo information along the bottom.
 
The SX50 looks sharper due to its additional depth of field, but thats an illusion.  I could stop the 100-400L down to get the same depth of field, but diffraction might make the image softer. 
 
In any event, the SX50 does a nice job in bright sunlight at similar settings.  If only focus was faster.  At 1200mm equiv, a moving subject is pretty difficult to keep in the frame.  I had to use the zoom out button on the left of the lens several times to center the lens, and then release the button to zoom in on the subject.  I think most people could do this fine, but I have verly little feeling in my hands, so if my finger drifts off a button, I don't feel it.
