Does Canon 24- 105 lens have a half-frame machine? Why does JD.COM Mall charge 7900, while the physical store charges less than 5000?

The only drawback of this lens with a half-width camera is that the wide-angle focal length is slightly not wide enough.

There is nothing to say about the picture quality.

Any lens in efs can't reach it.

If this lens needs a wide angle at the same time, it can be solved with 10-22 or with ultra-wide angle fixed focus. Actually, I think the focal length distribution is better.

And this lens is cost-effective, because 6d 5d2 5d3 uses it as a suit.

It's much cheaper to buy only 7900 detachable sets.

About 5000 yuan, the quality is the same as that of single purchase, even the packaging is the same. There are separate boxes, lens bags and so on, and there are also separate warranty cards.

Generally, the head and sleeves you buy are detachable.
