At any rate focusing is now very acceptable with the exception that the built in microphone or a shotgun mike mounted on camera picks up the noise of the focus motor. There are some work arounds for this including putting the mike off-camera, but the solution with the least hassle is using Canon STM lenses which were built to give silent operation in video mode. The downside is there are only a few models of these lenses and they do not use premium quality glass or construction. They are available only in the EF-S mount and must be used only on crop-sensor Canons. I acquired used copies of the 18-135mm f 3.5-5.6 IS STM and 55-250mm 4.5-5.6 IS STM lenses this spring from KEH in Atlanta, Georgia.
Both lenses perform very well for video and they do a decent job at still photography. It seems that my copy of the 18-135mm is a bit better built than the 55-250mm, but I really have no complaints about either considering that the 55-250 cost less than $300.00, while the 18-135 was under $350.00. They do not have the stinging sharpness of the L lenses for still photos and I miss the wider maximum f stop of lens like the 70-200mm f 2.8, but of course when needed one can still use the L lenses when needed in video mode and use work-arounds for the sound. The STM lenses were instrumental in causing me to use the old 7D quite a bit more this spring for still photograhy than I usually would have, as it was common to have whichever lens which was not on the 70D mounted on the 7D and lying close at hand.
I take few landscapes, but I used the 18-135mm for many of those that I did take. It compares well with lenses such as the 28-135mm IS in EF mount on a full frame camera, as with the 1.6 sensor crop factor of the 7D--70D, etc. this lens has a focal length equivalent of about 29mm--216m.
