Also as regards their type very well. While it's not quite as wertig like an L-lens, and a distance-adjustment scale you have to do without. I had most of my lenses for my crop camera either, so there was no big change for me at the 6D where I operate the lens. The missing seal I can take personally because not also present at the previous camera and lens Park. When I come in the rain times, the camera is packed into the backpack with rain cover and well-being of Use.
The lens has a Lock switch, so that the glass does not unload unwanted at 24mm. eg. while wearing. In normal use, when I slung the camera on the strap, this lock is not necessary, since it does not unload without activated lock. But if I had the camera in my little Slingbag indoors, it's already happened to me that the objective could not get to the bag walls to the side pockets when removing and export in the withdrawal process. In this case, I like to clean the lock.
What I do not like so much that comes the lens hood and I had to invest it again about 50. I knew that already though, still it's annoying. Lens I bought on Amazon, but the appropriate lens hood was not available. So I had to order from another supplier, who had one of the little aperture deliverable in stock. Do not understand why you are not L lenses just 25 - 35 sold more expensive, but mitliefert a stop! For other manufacturers going too!
Meanwhile, there are some reviews to the lens, and this confirmed my positive visual impression. In sharpness, vignetting and chromatic aberration, as well as a smaller Verzichnung at wide angle and a better stabilizer it even beats the "old" EF 24-105 L. Meanwhile benefits are just in the continuous aperture of F / 4, the seal and the bit wertigeren appearance and equipment (distance scale and lens hood available). But if I have to dim the L corresponding to come nearly to the edge of the STM, the advantage of the continuous aperture of 4 is also lost to me.
Priced enter the two Canon 24-105er not even so much when you buy the kit in the L (for example, with the EOS 6D). Thus, the STM will have a hard time to step out of the huge shadow of his L-brother, the very many users are very satisfied.
For my personal use me enough the simpler 24-105er, and it's fun to work with.
Personally, I'm glad to have IS STM opted for the "new" EF 24-105!
