Ok I need help in identifying lenses that are best suited for the 7D II and it APS-C sensor.
What lenses the best in sharpness, and what lenses are to be avoided.
I love the Canon L series of lenses and have a few for a full frame body, but I now see a new lens offering " STM " and was wondering about those.
It's been a while since I have gone shopping for any lenses but I am looking to two to go in the kit ..... one a " walk around " and the other a longer reach zoom.
In playing with the kit lens (18-135 IS --- NOT the STM variant ) I believe 300mm will suffice on the long end.
As to STM vs Non-STM ..... am I seeing things right that STM may be a better performer in sharpness? I know it has a different, quieter motor that is supposed to be good for videography but that is all I know about them ... at this point.
STM ("stepping motor") was developed to be quiter when autofocusing, which is mainly an advantage when making videos. But around the same time STM lenses came out, Canon improved the optics as well - from competitive pressures, I assume. So many of us look for the STM designation even when we are not interested in video.
Canon doesn't make any L lenses for the crop format. The L series is for full frame only. It is a marketing thing. People who don't know all the details look for L because they want the best. But those L lenses are not a good choice for crop cameras like the 7D2, because full frame lenses are bigger, heavier and more expensive. There are excellent mid-zoom lenses available now for the crop format.
For longer reach, the 55-250mm STM has been well received here at POTN, as Ramon also said. I own that lens and it is very nice.... however, for birding, I prefer the 100-400mm II. Yes, it is an L lens. If there is no crop version, then go for the L lenses. (But as Ken said, they are expensive as L. )
