Re: 50-200mm NON SWD V's SWD Versions

Physically, the SWD version is actually slightly lighter (not noticeable in reality) but noticeably wider in girth, probably to accommodate its new SWD ring motor. They have the same zoom extension and are about the same length when zoomed back to 50mm. They have the same 67mm filter thread, but the SWD version has a larger hood that incorporates a sliding hatch for access to a filter which may be fitted, like a polariser, so you can rotate it.

One fault that users of the original version sometimes notices was some flexing in the tripod mount collar. This looks like it has been addressed with a beefier looking collar.

Optically they look the same on paper, with 16 elements in 15 groups and the same closest focus, but on physical inspection of the lenses the optics look slightly different. The SWD version appears to have a slightly wider front element and the internals appear slightly different.

SWD focus does make a difference - it's very very fast and quiet, though the old version is also quiet.

As I said, I'll post some samples later.
