Tamron 18-200 mm VC for EOS M??

...shoot with 4 different brands of mirrorless cameras - those being Micro 4/3 (both Olympus and Panasonic), Fuji X, Canon EOS M, and Samsung NX.

The sharpest "kit style" zoom lens I've ever experienced that punches far above its weight (regardless of brand) costs anywhere from $249 to $299 on eBay (separated from the kit versions) is the awesome Panasonic 12-60 F3.5-5.6 OIS lens (equivalent to a 24-120 MM lens).

Right now I only keep the standard kit lenses (very good copies of them) on my EOS M cameras (15-45 and 18-55).  As I said, the Tamron 18-200 III is one that I would only attach if the ultimate clarity is not an issue - such as a take-anywhere lens.  So the only other lens I use for most scenarios is that Panasonic 12-60 I mentioned above - attached to either a Olympus E-M5 or an E-M10 Mk II.  I wish Canon would make a similar lens to this.  The Panasonic version is weatherproofed, is constructed well, and it's sharpness levels compete with the big boys for 3-4 times less the price of those higher priced models and gives you a 24 - 120 MM equivalent (where you wind up staying a good 95% of the time).  And it has a metal lens mount.  That would be an ideal take-anywhere lens if Canon were to produce something like that.

I didn't care for the Canon EF-M 18-150 F3.5-6.3 IS because it felt cheap to me and I'm not a fan of plastic lens mounts.  That's the big issue right now with Canon - in that they have a miserably small selection of EF-M lenses.  There have actually been more bodies released (beginning with the M) than there are lenses - go figure.

And I sincerely hope that Canon doesn't now put all of their mirrorless eggs into the Full Frame end of things.  I'd be p-i-s-s-e-d to the max if they went balls to the wall with FF mirrorless releases and then started releasing FF lenses to go with them at a rapid rate.
