I use the Sony 1.4x and 2.0x Teleconverters with the Sony 100-400GM Lens and share results on image quality, focus speed and focus performance while searching the Arctic for polar bears. Tested with the Sony a7RIII and Sony 100-400 GM paired with the 1.4x Tele and 2.0x Tele.https://youtu.be/A6Seehp2imkI found the optical performance of the 1.4x and 2x teleconverters when matched with the Sony 100-400 GM to be absolutely fantastic. Colors, contrast, and clarity all remain excellent. But there are drawbacks - watch the video above for the full story.Buy Links (Your use of these links supports reviews like this)Sony a7RIII: https://bhpho.to/2i7Z3F8Sony 100-400 FE f/4.5-5.6 GM: https://bhpho.to/2JIxM7FSony 70-200 f/2.8 GM: https://bhpho.to/2LfkuoTSony 1.4x FE Tele: https://bhpho.to/2JGWntMSony 2.0x FE Tele: https://bhpho.to/2Lev1APDownload RAW Photos to evaluate (For your personal use only)[gallery td_select_gallery_slide="slide" td_gallery_title_input="Sont Teleconverter Samples" ids="18611,18613,18612"]
