| Tamron 18-400mm f/3.5-6.3 Di II VC HLD LConan Mount | No | yes | yes | yes | Image capture area and viewfinder view does not automatically switch to APSC. This means hard vignette is visible in viewfinder. AF-S hunts but does eventually nail focus, accuracy is very high when it does. and the images captured also shows this hard vignette. Vignette is visible at all focal lengths at all apertures. |
