Sadly, the new SX PowerShot camera we told you was coming isn’t a replacement for the PowerShot SX60 HS, and a lot of people are going to wish it was.

Instead we get the PowerShot SX730 HS, a compact 40x zoom camera. There is something pretty cool about a 1000mm equivalent camera that will fit in your coat pocket.

PowerShot SX 730 HS Specifications (Google Translated0

  • Number of effective pixels: approximately 20.3 million pixels
  • Focal length: 4.3-172.0mm (24-960mm in terms of 35 mm)
  • Lens Speed: F3.3 – 6.9
  • Color: Black / Silver

so maybe this has a 1/2.3 sensor is my guess, is 20MP and has a 6.9 lens at the long end.

For this pixed density the system is clearly diffraction limited, which means it has no possibility to take sharp pics even with a really good lens.

Maybe less rang with more opening would have delivered better IQ, specially if taking camera shake into consideration

BUT more is better, more MP and more zoom range :). Diffraction is less imporatant to understand

Its a entry level super zoom and sells very well.  If you are going to produce a camera the masses want for the price they want, there will be compromises.  I'm sure that most who buy one will be very happy.  Those who want a $20,000 rig for a few hundred --???

I guess there are still some old schoolers out there that would buy this.

i did not tell that canan should not produce what the masses want. The masses want specs. I am joking that the masses not understand the physical limitaions, even some reviewers may write that the lens is soft at the long end :) the lens has FF equivalent opening of F39.

Maybe a camera with 15MP, 600mm max lengh and a F20 equivalent opening lens would give better results, taking into account that it would allow 2x shutter speed, and have less motion blur. Sure the specs would sound less spectacular

I have owned a number of these little jewels. People can say they will not get you great images. But IMHO they are still a heck of a lot better then the latest smart phone/camera on the market. And smartphones are what are taking over the market these days..

+ 180° tilting screen for selfies. SX720 HS has a fixed screen.

I have an old (10 years or so) PowerShot I use just for backpacking (which is probably only once or twice a year now), and for the size and weight and price, I'm always amazed at the photos.  I could use my smartphone these days, but it's a cheapish one, and I want to preserve the battery anyway (emergency use only).  And I'm sure others have similar, specific uses, making this more than just something for the mindless "masses."

You don't understand how diffraction works in the real world.

The amount of detail you gain from adding more pixels more than makes up for the small detail you lose due to diffraction.

It reminds me of those people who complain that "lenses can't resolve that amount of pixels". These people don't understand that even the worst lens in the world will be able to capture more detail, regardless how bad the lens you put in front of the sensor is.

And, most people don't have that 1200mm full frame lens costing and weighing the same as a car.

Sometimes it's not about how great the image will turn out, but if you can capture it in the first place!

This little camera can capture things a full frame camera will never be able to capture without a massive lens that 99% of users can't afford.

All cameras have their purpose. These little things have their purpose, they offer range in a tiny affordable package, and you turn in some image quality in return.

(and no you can't crop your 70-200 image and get the same detail, you're going to need that 600mm sigma at the very least)

Would it (in theory) be possible to use deconvolution to (partly) compensate for diffraction?

There's more and more processing power in digital cameras available, so why not use it?

Personally, I think these things are really useful and under-appreciated. 

I have an S120 in my pocket quite often, because if I'm walking around with 2 DSLR bodies, I can't capture the entire useful focal range without using a crappy lens (and even then, I can't go nearly as wide, unless I dedicate one body to wide).

Having a pocket camera lets me take that quick shot of something that's otherwise not in my focal range, without having to swap lens.  I briefly considered a mirrorless for this role, but really, they're still too big for a 3rd body because of lens protrusion (it's not comfortable to stick it in a pocket).

Oh, and another thing -- they'll let you take these into almost any concert.
