[Repeating this post because it's buried in a list of replies.]

Astronomy buffs routinely mitigate diffraction effects by applying software to images of the moon, nebulae, etc. See ImagesPlus at http://www.mlunsold.com. I couldn't find any B&A's, but I will trial the product.

Focus Magic (http://www.focusmagic.com) accomplishes a sharpening result that is somewhat better than CS5's Smart Sharpen. To me, it's worth the price, which is $65 US.

Mike Davis: I suspect the label "Diffraction Correction" exaggerates the effectiveness of this feature. No amount of processing can magically recreate actual subject detail that was lost to diffraction as the light passed through the aperture. It might be able to simulate what appears to be genuine subject detail, but it won't be accurate.

For example, assuming that all other variables affecting resolution are up to the task... If diffraction at a given f-Number is just bad enough to prevent you from discerning the date "2014" on the face of a coin lying on a table several meters from a camera equipped with a normal FL lens when viewing at 100%, "Diffraction Correction" isn't going to reconstruct that data from thin air when the data never got past the aperture in the first place.

You can't make a silk purse from a pig's ear.

ObelixCMM: So you are at the beach on the nice sunny day with your hot girlfriend, I know this is hard to imagine for some of the pixel pipers and gear heads on this site but work with me, she gets up and start walking away. You pick up your brand new FZ1000 to record this for bragging rights with you nerd friends and set it up at same settings from Dave Dugdale’s “how to video” you watched that morning on You Tube. You want that nice cinematic look, so you go for 4K at 24P and 1/50 of the second with lowest ISO. You look true the viewfinder and all you see is white overexposed nothingness, after couple seconds of panic you realize your aperture is at f4 so you go to f5.6, not much better, f6.3 you can see outlines, f7.1 little better, f8 there are some skin tones but still way overexposed. And that’s it, no more f stops, no ND filters and all you can think about is Sony RX10 with f16 aperture and built in ND filters

A Tiffen 62mm variable ND filter provides 2 to 8 stops of reduction. A little over $100. It's beginning to look almost mandatory.

Autoxave: The specs of of this lens is 25-400 mm/2,8-4. In terms of a FF sensor this will translate (equivalence) into 9-148 mm/5.6-10,8?

>F-numbers dictate how intense the light is - how many photons land on each square mm of sensor.

Intensity is photons per unit area PER UNIT TIME.

In reply to:

Fygaren: As you probably never frame your photos using diagonal AOV, to get the equivalent of FF 3:2 with mFT 4:3 or the other way around, you need to do some cropping.

FF 100mm f4 = mFT 48mm f1.9 and then crop vertical AOV to get a 3:2

mFT 50mm f2 = FF 92mm f3.7 and then crop horizontal AOV to get 4:3

Horizontal crop factor of mFT is about 2.1 while vertical is about 1.85

Cheers!

I shoot circular format. Sometimes even pear-shaped format. Awful results.

iAPX: I don't understand why this one has not been rebranded Leica, I will die for it with a high-res viewfinder, a better creen on the back, and a better construction (says $2000 for all of that).

Ah and Audi design, and nice finish as the leica C!

>The only real difference is the price.

I bought the Panasonic LX3 for roughly half the price of the Leica D-Lux 4. Wikipedia explains the differences--

The Leica D-Lux 4 is very similar to the LX3, sharing most of the design and the mechanical components. The main difference is the more pronounced grip on the LX3, the firmware which processes the JPG files in warmer hues on the D-Lux4 and the fact that D-Lux4 comes bundled with Capture One image processing software.

This red-dot malarky has got to stop.

Nukunukoo: Whoever does full sensor 4K for low-light performance and at 60P on a fixed aperture with uncompressed HDMI out and better than AVCHD codec on a bridge cam for less than a K gets my money!

4K flat-panels will finally give us the means to view our digital stills in all their glory!

Don't be thinking prints all the time, folks. Think slide-show.

aggressor: Nikon D3300 + Nikon 18-300 f/3.5-6.3, about 1000g total weight and about $1300 total price. Much better option, no?

>Much better option, no?

This is a trenchant question. It really trenches. No, seriously, if the IQ of the 18-300mm f/3.5-6.3 is comparable to that of the FZ1000 or the RX10, then it's a three-way horse race.

>Is there another competetor to these two cameras?
>(Maybe an DSLR/DSLT?) & (i dont need 4K)

Huh? Check out the brick building near the bottom right corner, and a yellow structure near it. There is no question about which one is sharper - of course it is Panasonic. There is not difference in the center, but FZ1000 clearly wins in the corners, at least at wide end.

[Re: photo of facade with classical columns]

>please look at the metal fence in left bottom corner. There is no doubt that Sony is sharper.

Correct! And the Sony is much sharper along the right-hand edge.

Argh! Adjudicate, someone!

Very good review. It has decided me in favor of the FZ1000. Thanks, everybody.

osv: why no testing of the parfocal capabilities of the lenses? i didn't see the word "parfocal" anywhere in this review, did i miss it?

i see rack focusing being attempted, but don't these cameras both have focus-by-wire lenses? you can't set rack focusing marks with that type of lens.

Hmmm. Really good question. In the many reviews of zoom lenses that I've read, this issue never came up. I guess AF could take care of any shortcomings.

But then, I don't read reviews of cine lenses.

In the wide-angle skyline shot, on the right-hand edge, the RX10 is noticeably inferior in IQ to the FZ1000. On the left-hand edge, I can't see a difference. In the lower right-hand corner, the FZ1000 seems to have slightly better IQ. In the lower left-hand corner, it's hard to tell.

I'm overjoyed that this is the worst of my problems.

Marty4650: This might be the perfect compact camera.

The only downside might be the price. I guess $800 just isn't as much money as it used to be.

The daily paper here in New Babylon just skyrocketed from 75 cents to $1.25. Better grab one of these Sonys before the price hits $1333.33.

Ha ha! This is a GREAT shot! I love sea gulls. They hang out in my neighborhood in Brooklyn, 5 miles from the Atlantic. Every now and then I see one standing in the road in the morning. I'll be needing a new superzoom to get some gull grab shots.
