dgdillmanI have both lenses. Here are some notes:
The new STM version definitely focuses faster, not the other way around. It is also quieter, and is less prone to "hunting." One thing to note though is that the old focus ring was mechanically linked, whereas the new one is electronic. This means that the camera must be on to focus manually, and manual focusing still makes noise as it is using the motor.
The build quality is better period, not just the metal mount.

pkconnollyI'm not a Canon user but some of the Sony e mounts have a 49mm filter ring , 55-210mm, 24mm and 35mm I think. Prices seem to be the same for the cheap end ones I've been using and usually 70+mms are more expensive.

New lens (just introduced at the end of May 2015): 7-blade diaphragm Metal mount New STM (stepper) motor Slightly shorter minimum focus distance 49mm filter ring (less standard, more expensive filters)
Old-style lens (the one in this drop): 5-blade diaphragm Plastic mount 52mm filter ring (standard size) Actually focuses slightly faster than the new version
Same: All optics use the same glass design since the 1987 version of this lens! Newer ones are coated better.
Is it worth the extra $45 for the new features (assuming this gets down to $79.99)? Your call. The 7-blade aperture will give slightly different effects in certain uses. The metal mount should be more durable, but I haven't seen reports of the older plastic mount failing a lot. The metal mount makes it a little heavier. The more expensive 49mm filters also add to the price difference, assuming you want to protect your lens with a filter.
