Sony 1.4x and 2x Teleconverters. How Good Are They?

/

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"]

Super Zoom Video with the Sony a7RIII

https://youtu.be/1-slnohI_csWhen shooting video with the Sony a7RIII you have two modes you can make use of to more than double your zoom.

  • I have on the 100-400 and at 400 I can turn on aps-c crop which gives me an additional 1.5x crop 400 x 1.5 = 600mm

  • Turn on Clear Image Zoom and you can zoom in an additional 1.5x for a 900mm reach.

There is no quality loss - this is still beautiful 4k footage! 

I mentioned this in my review of the lens - if you have the 1.4x teleconverter you can get some ridiculous reach while still shooting beautiful 4k footage. (1260mm!) Your noise does start to increase and stabilizing your camera at these longer distances can be difficult.What I really like about the a7Riii - you can assign custom buttons for each mode of the camera (stills, video, playback) During video I have assigned C4 to turn on APS-C mode and the AEL button to turn on clear zoom.  Once clear zoom is active you can adjust the amount of zoom with the joystick or the control wheel. There are two modes of clear zoom - stay away from the Digital zoom THAT WILL degrade quality.
