More good news for 645 shooters:

There will be a new SMC-FA 645 Zoom150-300mm f/5.6 lens for the AF 645 introduced in two weeks at PMA. It's less than 8" long (though barely) and weighs only ~32 oz., so it looks to be pretty compact for a medium-format zoom.


There are also some rumours from very credible sources that a new, even smaller version of the 67 is coming - possibly not ready for PMA though...
