I just finished testing Sony’s new 100-400mm F5.6-8, and this little lens turned out to be more…umm…interesting than I expected.

Sure, it’s incredibly small, light, affordable, and the autofocus is surprisingly snappy. However, there are a few compromises once you start looking closely at sharpness, low-light performance, backgrounds, stabilization, cropping, and that F/8 maximum aperture.

In the video, I compare it directly against Sony’s faster 100-400mm options, test both teleconverters, look at cropping versus the 1.4X, and break down who I think this lens makes sense for, and who should probably skip it.
