Re: SX50 outperforming 5DIII +100-400mm

I weent to our local Best Buy and looked a SX50 over also the Sony equivalent.  Even though the lighting is plenty bright to get fast autofocus with my 100-400mmL and 5D MK III, the camera would not focus at all when zoomed out to about 10X.  The Sony was much worse.  I tried on very well lit areas close to the bright lights,  ..,.nothing.  It did focus up close.
 
I was underwhelmed, I can't imagine being able to use it except in bright sun, and then AF might take a few seconds.  So much for that idea.

Well, I have been testing it in Hong Kong and Kuala Lumpur under very poor light conditions with dense cloud and some mist all day, all  @1200mm. Here is a 100% crop of a Robin taken before leaving (f/6.5 iso 640 1/320); then 3 full frames each reduced 3x in pixels for uploading: the Sparrow is f/6.5, iso 200 1/15 (yes 1/15 of a second); the Indian Mynah iso 200 and 1/125; and the spotted Dove at f/6.5, iso 200 1/60.

Seems to work for me. I have tried both servo on and off, and prefer at this stage to turn it off. I even got a Black Kite in flight.

Even overcast days outdoors has more light than we sometimes perceive, and indoor lighting is probably poorer than we percieve.  However, none of the other models with shorter zooms had the issue that the 50X Sony and Canon had.
 
Certainly it won't beat a 100-400 inside a building with excellent lighting, but thats not where I'd use it.  Since I could not test it outdoors, I'm wondering just how long does it take for your camera to focus at 1200X after you turn it on and focus the first time?
 
I might buy one where I could return it if it doesn't perform.

f/6.5, iso 200 1/15 tells you the light levels. The focus didn't seem particularly slow. The electronic viewfinder works quite nicely and you press the camera to your face when composing and shooting. The camera also gave some great group photos in indoor shots in restaurants at 24-40mm equivalents, which is something you can't do with the 100-400! So, I think that this a great little camera to have at hand that can capture some wild life at great distance. It's not going to replace my 5DIII!

I guess I'll give it a try.  It does sound like a useful camera for the price.  I was a bit surprised at the large size. but its still small by comparison.
It might make a good camera for those on vacation who don't want to pack around a big DSLR,  or hiking where every ounce counts. 
 
Who knows, I might sell my 100-400mmL :)

So please explain how that is "outperforming" it?

Simply, the detail or resolution from the SX50 at 1200mm is better than the 5DIII +100-400mm at 400mm. If you take a crop from the 5DIII combo to give the same view as the SX50, the SX50 image is better. This is useful if you are taking a bird photo which requires heavy cropping from the 5DIII and 6x less from the SX50.

As I had in the first post, I am not implying the SX50 is better than the 5DIII but the extra reach at 1200mm beats out the 100-400mm at 400mm. That is quite remarkable and unexpected to me, and it means I can travel light. Normally, I would use the Canon 5DIII with a 600mm prime, and only use the 100-400mm when I had to travel with limited luggage. But, for work trips I'll just take the SX50 for from now on knowing I can get some spectacular shots.

So you're taking a crop where only 1 pixel out of every 9 on the 5D Mark III is thrown out, and you're saying that a point and shoot is better.

This would require your 5D Mark III to have 10 TIMES the starting resolution to get a better result.

No wonder you came to the conclusion you did. Now try the 5D Mark III with a 2x teleconverter and a 400mm lens vs the SX50 @ 800mm.

In some narrow definition you are correct.  But most meaningless and definitely not useful to most photographers.

Please read everything that has been written here. I routinely use a 5DIII with 600mm of L lens attached for bird photography and am happy to cart this gear around because it gets superlative results. When I travel light by plane or have a few minutes to spare on a business trip, I usually take the 5DIII with a 100-400mm for bird photography, which is still quite heavy and not in the same IQ league as the prime lens. I have found that for bird photography I can use the SX50 and sometimes get better results with the 100-400 set up.

Regarding your suggestion of putting a 2xTC on a 400,  I have tried a 1.4x on the 100-400mm L and the 5DIII. Aside from the autofocus being horrible, the IQ is degraded so much that there is no advantage in using the lens without TC and rezzing up 1.4x. A 2xTC would be even worse.

Regarding the comment by RGF about not being useful to most photographers, CanonRumors represents only a tiny fraction of photographers - those of us who are primarily interested in high end gear and the highest IQ. There are 100s of millions of photographers who want tolerably good kit that they can afford and easily use to get acceptable results. Cameras like the SX50 have huge popular appeal and can be useful to us as well.

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 1200mm or even 600mm lens, therefore this little camera looks like a great deal ... and it shoots RAW!.. finally!
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.
