I am considering a lens for my Canon T6i, the choices are: Tamron 16-300mm f/3.5-6.3 Di II VC PZD MACRO Lens or the Canon EF-S 18-135mm f/3.5-5.6 IS STM MACRO Lens.
Anyone have experience with the two lenses
Thanks
I'd take the Canon lens over that "super range" Tamron zoom any day!
PZD = Piezo focusing motor... same as the "micro motor" focus drive that Canon uses in their cheapest lenses, and the slowest, noisiest form of focus drive systems.
STM = Stepper focusing motor... quieter, smoother, faster. (Although not quite as fast as USM or "Ultrasonic" focusing motor... a new version of the EF-S 18-135mm is available with that for about $50 more.)
There's no guarantee that a Tamron lens made today will work on a Canon camera in the future. A third party lens like that might become an expensive paperweight if you upgrade cameras some time in the future.
"Super range" zooms.... some people love em because they can get by with just one lens to "do it all". Nice for travel, perhaps. But that type of zoom often doesn't do anything particularly well, so I've always avoided them. Apparently some of the ones offered today are better than they've been in the past, but I'd still rather have two or more separate lenses... such as a kit with Canon EF-S 18-135mm, EF-S 10-18mm IS STM, and a telephoto such as EF 70-300mm IS USM, EF 70-200/4 IS USM or EF 100-400mm IS USM II... or even a prime such as EF 300/4 IS USM.
After all, the whole point of buying an interchangeable lens camera is to be able to interchange the lenses to adapt the camera for different situations. Seems silly to me to then buy a single lens and expect it to "do everything". Could have saved money and just bought a non-interchangeable lens camera instead!
Incidentally, if you are interested in shooting video with your T6i, the 18-135mm STM lens is a better choice (smoother and quieter autofocus). Normally, USM lenses are better for sports (faster than STM), but not as good for video. However, the new EF-S 18-135mm IS USM uses a new type of "Nano" USM that makes it the best of both worlds... 2X to 4X faster focusing than STM, so better for sports/action shooting... But also quieter and smoother than most other Canon USM lenses, making it a good choice for video, too.
In addition, videographers might be interested in the "power zoom module" Canon is offering for use with the EF-S 18-135mm IS USM lens (exclusively, so far).
Either type - STM or USM - are faster focusing than non-STM/micro motor or typical Piezo motor lenses.
