[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.

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.

The theft lies in stealing another person's labor.

The stealing of labor is one half of the definition of Capitalism.

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.

Really nice shot. Balanced. Invites close observation. Intriguing.

Those bloated plutocrats should simply give Huff a few million for the lot and have done with it. But no, they want it for nothing.
