Is the leica vario elmar sl 100 400mm f 5 6 3 good on aps c?

Yes, it works well on APS-C, and the site's own numbers make the case. On an L-Mount APS-C body it frames like 150-600mm on full frame, which is a lot of reach for the money and weight. The trade-off is the f/5-6.3 aperture: at the same framing you get depth of field closer to f/7.5-9.4 on full frame, so you'll need decent light or a higher ISO for fast action.

The lens is stabilised and has autofocus. It fits the Leica TL, TL2, CL and T, plus the APS-C-friendly Panasonic bodies listed on its page. If you're shooting birds or wildlife, the wildlife and sport guide explains why an APS-C body with a 100-400mm-class zoom is the best-value reach. For the crop maths, see the focal length converter.
