Okay folks, here's a gen-u-ine question with gen-u-ine Pentax content.
In Washington I was able to crack my pile (blecch) and get to grips with
a new lens, the Canon 24-70 2.8 - and immediately I noticed it did one
thing which surprised me.
At 70mm, the lens is compact (LOL) and at it's 'normal'

My Sigma 28-70 f3.5 (KA mount) does this - it also comes with a metal
lens hood that I leave on full-time to protect the zoom mechanism. I
like the feature. :-)
Of course, now that I have an M50 f1.4 and a M28 f3.5, that zoom has
been consigned to the spare-lens drawer :-)
