I must admit this is pretty impressive for a 1200mm P&S :)

Impressive!!! :)

I must admit this is pretty impressive for a 1200mm P&S :)

That's got to be the understatement of the year......

This is making me re-think my strategy for a hiking camera.... I have been avoiding P/S cameras because they quality just was not there.. things appear to have changed!

I had to spend some time in LR4 to make it look like that :) . However, I think that I will never own a proper
Now I'm curious, if it is possible to make a 1200mm zoom P&S with a little larger sensor, like the one in G15. How big could it be?  ::) That would be something really cool, even if it had no wide angle, like 12x 100-1200mm eqv. dedicated super-tele-zoom.
Its possible, but the SX50 already has a large body and the lens is a large diameter and pretty long.
 
I think you know this, but it is not a 1200mm lens, it has a 4.3-215mm lens, so the crop factor is 5.58. 
 
 
The G15 has a crop factor of 4.5, so the lens would need to be about 267mm which would make it longer and bigger in diameter.  The body would have to get bigger than the SX50 because of the lens size.  The length and diameter are determined by the 267mm focal length and the f/6.3 aperture.  Its a size versus focal length compromise.

Yes, I'm aware of that and I don't mind if it had a Rebel-size body with built-in 55-250mm or even 70-300mm caliber optics.

The trend is toward smaller sized bodies, I'd doubt if they make a bigger P&S, but email Canon with your wish.

Well, it is smaller than the real 1200mm lens, much smaller :D ... and less expensive

Had very little chance to test much in Singapore. Just one brief trip out in poor light again. Not many keepers but the two attached out of about 50 made it worthwhile. To reiterate, I am just having fun taking photos with this lightweight camera, the quality of which compares well with the 100-400L on an FF when you get it right. I will test it further when I get back in my favourite bird site where the waterfowl tend to be far away and move slowly, which should be perfect if the light is good. The two attached are a close up of a Rainbow Lorikeet and an amusing one of an (?) Australian Pelican - work it out - which is a 100% crop from the far distance. The Lorikeet is reduced by 3x.

Thanks Alan, please keep us posted. 

I recently upgraded from the 7D to the 5DIII.  I have pretty much decided to sell my 7D, but am among those that have thought about keeping it "for reach" with the 100-400L.  I am aware of your and others who have argued that there isn't much to that.

But now, perhaps I sell the 7D, and pick up the SX50.

as much as SLR gear has improved in the past decade, PnS cameras have improved leaps and bounds more.
They are quite usable for a lot of things, especially when you have the flexibility of raw files.

I regularly use G-series PowerShots for serious imaging of stationary subjects.
I did play with a G15 a few days ago, AF speed is much improved, even the switch to their own in-house type sensor has made for (surprising to me) improvements as well.  I hope this tech does trickle up to the next crop bodies.

back before I got my first DSLR, I made good use of a Panasonic DMC-FZ20.  a 12x constant f/2.8 stabilized lens was a huge fun factor and it worked extremely well.  Too bad the sensor got pretty noisy above base ISO.
With that, or eve better lenses now, on today's sensor tech, no good reason why a superzoom compact can't be a capable camera, as the OP has well demonstrated.

I haven't considered a superzoom PnS for a while either, thanks for opening my eyes.

SX50 compared to a 60D with various lenses:

First 70-200F4 at 200mm
Second 70-200F4 with 1.4 teleconverter
Third Sigma 120-400 at 400mm
Fourth SX50 at 1200mm

All pictures are 600x450 pixels cropped from the center of the frame.

Pictures are minimally processed in Lightroom. Note how teleconverter caused loss of contrast, plus the Sigma lens has much less contrast than the 70-200. I was very impressed with the colours out of the SX50.

I decided to try one out today, so I took my SD card, and went to our local camera store, Huppins (www.onecall.com).  They had a demo, but indoors, it would have required 1/15 sec at ISO 1250, so that was out.  They will match B&H prices, but they were out of stock except for the Demo.
 
We went outside and snapped a few images, being careful to hold the camera as steady as possible.  I found it was a bid difficult, and AF was very slow, around 2 or more seconds.  Once you get it focused, then its ok unless you drift off the target too much.  It certainly is not a sports camera, not at 1200mm anyway.
 
Here are some of the sharpest images.  I included a 100% crop, its not going to be pretty as you might expect. They can be improved with a little PP.  I did take jpegs using the dreaded green box setting, since the camera battery was getting low, and I didn't have time to set it up for RAW.
 
Still, it seems like it gets useful images at extreme distances as long as the light is good.  A tripod or monopod would be useful when lighting is difficult.
 
215mm (1200mm equivalent)

 
 
100% crop, kinda meaningless at 1200mm equiv, so don't obsess over it.
 

 
 
 
Another at 1200 equivalent
 

 
 
and the crop.

Those photos of Ospreys are really useful - just what I would liked to have done. The complete SX50 camera at £350-400 clearly outperforms in telephoto bird photography the Sigma 120-400, which costs £600-800 just for a lens alone! The Sigma open wide at 400 is f/5.6, which is hardly brighter than the SX50 f/6.5 at 1200mm. The Sigma may have much faster autofocus, and a 5DIII has superb high iso noise, but for relatively static photography in good light, which is what most of us do for birding, the SX50 wins hands down - the quality is far, far better.
Thanks

I admit that this is using the camera under ideal conditions.... and that in poor light or with moving targets that a DSLR with good lenses should do much better, but the fact that in good light with a stationary target that I would need a $10,000 lens to get the same shot absolutely floors me.  Yes, I am planning on getting a 7D2 and if they ever come out with it, an upgraded version of the 400 F5.6 for bird photography..... but this "toy camera" has just become an integral part of my kit.

Shoot out with 5DIII + 300mm f/2.8 II + 2xTC III

Back from the Far East and decided to pit the SX50 against £9000 of supersharp 5DIII + 300mm f/2.8 II + 2xTC III. The big money does win, but the SX50 is not disgraced. Here is a greylag goose shot with both. The SX50 is not as sharp, but is still very good. I think it is really better than the 100-400L.

2 seconds to focus is not my experience - that long time must have been an artefact of usage. My experience is that in the field the focussing is very fast. It has a very clever feature that the focus tracks the object in the centre square just by pointing at the subject so when you press the button halfway to focus and do the exposure, the subject is already in focus. This is perfect for shooting birds that are relatively static - the effective focus time is close to instantaneous.

The two photos are each reduced in size 3x for uploading.

To make a fair comparison, I have the 5DIII at 100% and the SX50 cropped and scaled down to same size.
The jpeg of lower quality (650kb vs 3.2mb) for uploading. The SX50 is not as sharp,
The SX50 is a digiscoping killer.

This collage has the head of the goose that was at the centre of the SX50 image, compared with that from the 600mm on the 5DIII, which is scaled up. You can see that the quality is better at the centre and the SX50 is only slightly worse.

thanks for the comparison. I'm not surprised. After all, the low pixel density 20 MP sensor on the 5DmkIII really isn't designed to maximize detail and allow for anything but the most conservative cropping. That camera has other priorities. Anybody who's shot with a D800, or even an entry level 24MP APS-C or micro 4/3s body knows that pixel density of upwards of 50+MP would be required for a full frame sensor to match the result of smaller sensors when heavy cropping is required, which pours cold water on the bogus theory that we've reached the usable MP limits of FF sensors. I have hope for such cameras to come in 2014 and the glass is certainly up to it for APS-C sensors demands more than any full frame sensor and when you crop, the edge performance is less critical than the center.

I was very impressed with the m4/3s system and its ability to deliver comparable or superior images to what used to require telephoto lenses costing north of 5K for a fraction of the cost. As such, I'm not at all surprised the SX50 beats the 5DIII. I'd bet it can probably beat the D800e which has only has a pixel pitch equivalent to a 16MP APS-C sensor. It doesn't even push today's APS-C specs in terms of pixel density much less m4/3.

Consider you did this with a consumer grade SX50. If one of the big camera OEMs decided to start producing a line of pro lenses and bodies designed with small sensors, super fast AF, and features designed to serve the big telephoto audience's demands, THEY'D BURRY the competition and those huge 10lb setups for good. Off course, canon would never cannibalize its profitable big lens niche but maybe somebody else will.
