get two different shots via PP: one should has exposure correction to show unburned sky. Another one should be exposurecorrected to show ground. Then you can blend these two images with exposure fusion. Enfuse - PanoTools.org Wiki
This method (exposure fusion) differs from HDR. HDR methods work with high dynamic range pictures by mapping its tones to narrower range (that can be represented on paper, etc). Unlike them, exposure fusion methods works by weighting each pixel of given images (assuming they are representing exactly the same object) and then combining the result pixel as a weighted sum of pixels. It's not that simple though, artifacts tend to appear at high contrast edges. This issue can be overcomed by different methods, the enfuse tool I put link at uses multiresolution spline technique, which bases on gauss and laplace image decompostions.
IMO the results taken with exposure fusion are usually much better than ones taken with HDR.

Congrats! Both are nice lenses. I regret a little I've sold my 77, it would be a nice combo with NEX-5N.

No, I'm selling my pentax gears.
And I wouldn't prefer FA* 85 to 77Ltd: it's too heavy and boring (although AF speed is excellent).

Like the 31
It's just impossible to see something as wide and sharp and fast with our tiny sensors )

The 77Ltd designed for the FF in mind (film surface actually). So it's not contrast enough wide open on APS-C.

Agree. Both 77Ltd and 31Ltd has fantastic sky rendition. Much better than one of 43 and even Distagon 21.

Soft sun light (it was a slight haze) behind, reflector highlights the man's face :)
The subject placed on about the same line connecting the reflector and the sun.
BTW, great night shots, v5 :)

My advice is to take 31. It's just better.

I made my boat.
Everyone must shoot boat (either with gun or camera). I did one but didn't noticed it until this morning.

That is properly made 31Ltd, as well as 77.
I don't particularly like 43 though.

Nice pano. I like using 31Ltd as super-sharp wide angle lens too :)
thank you!
