New lens comes with free hernia

Damn–this new Sigma lens (200-500mm, F2.8) is a beast; see details (which omit the key question of weight).  No word on whether this thing ships with its own crew of sherpas.  Of course, it’s still no match for that 500+ lb custom Zeiss monster, but it’s impressive nonetheless.

64 bits are *magic*…

Er, aren’t they?  What’s the real story?

ZDNet’s George Ou suggests that the Photoshop team is deficient in not making Photoshop CS3 a 64-bit app:

x64 allows high performance computing tasks to run extremely fast and efficiently. The free Paint.NET image editing application, for example, is fully optimized for multi-core and x64, yet Adobe can’t get its act together and won’t even release an x64 edition of the upcoming Photoshop CS3… It’s just a crying shame for Adobe to lag behind, because Paint.NET has shown tremendous speed increases using x64 for filtering and layering effects on the order of 50 to 100 percent speed boosts. Adobe should have been supporting x64 two years ago and it won’t even do it next year.

Meanwhile, Paint.NET developer Rick Brewster commented on Photoshop architect Scott Byer’s post "Photoshop: 64 bits… when?", saying that they got speedups in certain routines, but still aren’t matching Photoshop’s

Yup the reason Gaussian Blur shows such a big win in Paint.NET is due
to its use of 64-bit math. Photoshop seems to have some secret sauce
that enables its implementation to be much faster regardless, so props
on that.


I’m not saying that 64-bit computing doesn’t offer some advantages; it does.  I am saying (and have been saying) that the story is a tad more complicated than "Adobe can’t get its act together."  I don’t like the idea that we’ll have to pursue a certain path and accept the consequences (breaking plug-ins, eating more RAM, etc.) just because it would look good on a spec sheet.  We’ll do the right thing because it’s the right thing, not because it’s buzzword-compliant.
