High-quality zoom lenses are expensive, usually running over $2,000, and as such, most of us are always looking to get more mileage out of what we already own. The thought of doubling your zoom’s reach with an affordable 2x teleconverter is definitely appealing, but will it work in practice? This great video review takes a look at the situation for Sony shooters.
Coming to you from Tim – AlphaShooters, this excellent video comparison takes a look at the Sony FE 70-200mm f/2.8 GM OSS II paired with the FE 2x Teleconverter (making it a 140-400mm f/5.6 lens) compared to the FE 100-400mm f/4.5-5.6 GM OSS. In addition to the loss of two stops of aperture, traditionally, you sacrifice autofocus performance and image quality with a teleconverter (especially with a more extreme 2x model). However, in this case, the loss of aperture essentially brings you in line with the 100-400mm lens, and more importantly, the autofocus performance is quite impressive (it certainly surprised me). On the other hand, you also have to consider if the loss of sharpness is acceptable for your work, but overall, I was quite impressed and rather surprised by how well the teleconverter performed. It seems like a viable alternative to another expensive lens if you would like to save a nice chunk of change. Check out the video above for the full rundown.
